Stuff 'n Things

As a mild winter turns into an unusually nice spring here in Beaverton (last week we had multiple days with clear skies and highs in the upper 70s °F), a young ham's thoughts turn to portable activations, Field Day, SOTA, and the like. I've been looking forward to this summer for the opportunity to take the CC1 out in the field, but I may not get to be quite as adventurous as I hoped. Last winter, I slipped in a wet patch on the concrete in the garage and hurt my knee. As a typical guy, I didn't go to the doctor to have it checked out, I decided to "walk it off". It did heal, but not completely. So I finally gave in and saw my doctor about it a few weeks ago. She strongly suspects a torn meniscus, and ordered an MRI to confirm it. Unsurprisingly, my insurance company denied coverage on the MRI, instead expecting me to do a bunch of physical therapy based on at best a guess on what the problem is. Coming from a technical background such as mine, this boggles my mind. When you have a problem and you have the tools to make a measurement, you make the measurement to see what's wrong, not just take a course of action based on a guess! I understand that money is the driving factor behind this decision, but it still seems like a waste of resources for both myself and the insurance company. Not to mention that I don't have the faith in the efficacy of physical therapy that consensus medicine does.

So now I have to decide whether to shell out beaucoup bucks on physical therapy that probably won't do anything other than siphon money from our family to their coffers. And if that fails to miraculously heal the non-specific "knee pain" referred to by the insurance company, then I guess I get the privilege of paying for the MRI that I should have had in the first place.

I'm completely fed up with politics, so I have no desire for a political battle in my comments. I'm quite aware of the history of employer-provided health insurance in the US, and the effect of government distortions in the medical marketplace. There's plenty of blame to be handed out all around, so let's just leave it at that.

Anyway, I may not get to do any SOTA summits this year (except for perhaps a super-easy one such as Cooper Mountain right on the outskirts of Beaverton), but hopefully I can at least get out with the CC1 for portable ops to the park or while camping.

Speaking of the CC1, it's at a bit of a lull in its development right now. I'm waiting for all of the beta builders to complete their construction so I can be sure that I have all of the major hardware bugs worked out (which looks tentatively promising right now). I still have quite a bit of firmware coding to work on, then I'll be ready for the next (and hopefully last) PCB spin. With any luck, that should come in about 8-10 weeks.

In the meantime, I want to work on some side projects, and perhaps some opportunities to raise more capital to fund CC1 development. In that regard, I've been looking at a neat part recently. It's a MEMS VCXO from SiTime called the SiT3808. What's cool about this part is that it has linear voltage tuning, so that you don't have the uneven tuning response like you would from a varactor-tuned VCXO. The phase noise on the spec sheet also looks very good. I ordered some samples for 7.030 MHz and 28.060 MHz and breadboarded them to test the frequency stability. It was nothing short of amazing. The 7.030 MHz part had a long term drift of 5 Hz in 1.5 hours. The 28.060 MHz part drifted only about 20 Hz in 2 hours. That's pretty spectacular for CW use.

Since the 28 MHz part was so stable, I created a QRP transmitter for it by adding on a keying circuit and a couple of BD139 amplifiers. It outputs a very clean and stable 2 watt signal and has a tuning range of about 20 kHz. I also was fairly easily able to create a TX offset circuit, so that the transmitter can be paired with a direct conversion receiver (which I plan to do soon). Since tuning is linear, the offset is the same anywhere in the tuning range, unlike a typical varactor-tuned crystal oscillator.

I've been thinking about a way to introduce these parts to the ham community, since I don't believe that I've seen them mentioned by any homebrewers or used in any kits. Last week on the qrp-tech listserv, K7QO proposed a group build of the venerable NE602/LM386 direct conversion receiver (this one from chapter 1 in Experimental Methods in RF Design). Since this design is so well known, it seems like a "remix" of this design using the SiT3808 as the local oscillator might be a fun way to spread the word about the product. I breadboarded a version with the 7.030 MHz SiT3808 sample, which you can see below (the SiT3808 is in the upper-right corner, and it obscured by the tuning pot wiring).

NE602/LM386 Prototype Receiver with SiT3808

NE602/LM386 Prototype Receiver with SiT3808

It works exactly as expected. Wide open band signals directly dumped down to baseband, and a nice, stable LO. This particular SiT3808 part number only tunes about 4 kHz, but I will be able to get parts with a greater tuning range. I'm consulting with SiTime right now about bulk pricing, and hopefully I'll be able to do a kit run of at least 100 of these bad boys in the near future. Let me know in the comments if this is something that may interest you.

So that's my big rant for the day. Stay tuned for further updates on all of these projects in the near future.

PJ2/K8ND

The Thrill of QRP DX

Last night after the rest of the family was in bed, I was hacking on the CC1 firmware to add the BFO calibration routine so that I could get an accurate readout of my receive frequency. After successfully completing that task at the late hour of 0130, I decided to cruise 40 meters to see what was going on. Normally the best time for 40 meter DX at my QTH seems to be from about 0200 or so until sunrise, so I thought I might catch something.

Scanning below 7.030 MHz, I came across a very loud station. I figured it was somebody in CONUS, but decided to listen for an ID just in case. It actually turned out to be PJ2/K8ND in Curaçao. Not exactly rare DX, but it's still quite a ways from my QTH and it's a new one for me. So I figured I would take a crack at it with the CC1. Long story short, I set the CC1 in XIT mode and after an hour of trying, my 3 watt signal finally managed to crack the JA-wall. I was pretty excited! Not exactly a heroic snag in the annals of DXing, but it was a good one for me. My single HF antenna is a ZS6BKW only up about 30 feet, so busting a 40 meter pileup to a station 6000 km away made my night. My first DX contact on the CC1! Even better, I woke up to find that the FB op uploaded his log to LoTW immediately, and I've got +1 to my DXCC count.

QRP is fun!

Inflection Point

Hello there. Yes, there is still life at this blog, although whether it is intelligent is still indeterminate. I feel awfully guilty about the lack of content for the blog in the last year, but I've been in a horrible time crunch since getting Etherkit off the ground. When it comes to making the choice between moving your small business forward so you can feed your family or writing a vanity blog post, I'm sure you know which will win pretty much every time. I have no intention for the blog to fade away, so I hope that you all will keep me in the feed reader so that when the time crunch eases up a bit, I can get back to blogging more often and can share some interesting stuff with you.

Anyway, on to the main point. For a fair bit of time now, I've had a vague impression that something was going a bit sour in the online QRP/homebrewer community. It never really surfaced consciously all that often, but I distinctly recall there being a general aura of discontent around my feelings about the state of the community. It has dawned on me that even though we have more communication channels available to us than ever before, we are becoming increasingly insular and fragmented, even within our own little sub-hobby. I don't think it's a coincidence that this has happened while our choices of online communication channels has exploded.

I'm going to attempt to put some substance to this impression, with the hope that if I'm right about it, that maybe I've planted a seed for a way forward in one of my readers. This is probably going to come across as a bit of an Airing of Grievances, but that is not the point of this post at all. I will give you supporting data for my point of view, but I also intend to take a critical look at myself as well, as I'm sure that I've also made plenty of my own mistakes.

I believe that I got my first wake-up call a few months ago, when I learned that one of the most esteemed members of our group, Wes W7ZOI was hanging it up on his online amateur radio technical activities. Not only that, but whatever his motivation for withdrawing, it was also strong enough to make him pull all of his previous content off the web. This hit me like a punch in the gut. Wes has always been a most gracious virtual Elmer to many of us out here. He always seemed eager to pass on his enormous breadth of knowedge to those who asked for help. I have no knowledge of what transpired to change his mind about our community. The only public clue seems to be this quotation left behind on what's left of his technical web page:

I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely, in your thoughts, advanced to the stage of science, whatever the matter may be.

Whatever the catalyst was, Wes seems to be leaving us based on some negative experience. I can't begin to tell you how much this troubles me. People like Wes are an extremely rare treasure in any community, not to mention one as small as ours. I can't draw any firm conclusions based on the very limited information that we have, but it is not a good statement on the health of our community when such a luminary finds it worthwhile to withdraw, instead of continuing to engage.

The next data point I present is a blog post from John AE5X, published earlier this month. It's a succinct entry, so I suggest that you click over and read it for yourself. In the case that you don't, the Cliff's Notes version of the post is a reflection on the changes in the QRP community in the last decade. Some of the relevant ideas that I'd like to point out are:

QRP-L was alive with real content. People were talking about the latest kit they built and what they were doing with it. The QRP contests and events were well attended, providing further topics for discussion on QRP-L. Norcal 40A’s, SST’s, great rigs from Small Wonder Labs and Oak Hills Research could be heard, worked and talked about.

There was diversity among QRPers too – the hang-a-wire-in-a-tree gang and the QRP DXers all rubbed shoulders on QRP-L. As a result, all QRPers were exposed to various aspects of the 5-watt realm.

and

On the negative side, QRP-L is little more than a small circle of the same dozen people making 90% of the posts that occur there with the real meat of QRP technical discussion taking place on a specific rig’s dedicated YahooGroup. Ditto for the operational aspects of QRP: SOTA and IOTA have their own forums, leaving QRP-L relegated to sharing space in the dusty bins with newsgroups.

and

I am more thankful than I can describe at the exposure I received to ideas, techniques and equipment on the old QRP-L. That doesn’t happen anymore with the real brain power having been sucked away to specific forums.

John hits the nail on the head. I started being active in QRP a bit more a decade ago, right at the same time about which John is writing. And my memory is exactly the same as his. There was an excitement, vitality, and cross-pollination that made QRP-L nearly indispensable to both the QRP operator and the QRP homebrewer. QRP-L was pretty much the only game in town, at least on the online frontier. Today, it's a pale shadow of its former self. Nothing new is happening. Hardly any new blood is joining (or if they are, they are not speaking up). At least that was my last impression of it, because I rarely even look at it any more. I'm still subscribed to QRP-L (and a handful of other listservs), but I admit that I hardly even open up the Mailing List folder in my mail application any more. The amount of worthwhile content just doesn't seem worth it any more in exchange for the time spent sifting through the flame wars, pissing contests, and endlessly regurgitated arguments.

I don't mean to pick on QRP-L, but I think it's very illustrative of the issues we face. Almost all of the best and brightest has left, for one reason or another. And yes, people have been bemoaning the death of QRP-L for years. I bring it up because I think it's a leading indicator of the state of our online community. One of the most important statements in John's post is where he identifies the brain drain to all of the tiny little niche forums in our already-small sub-hobby. The QRP-L exodus happened in earnest years ago, but I think we are now starting to see the second order effects of this phenomena. We have scores of Yahoo Groups, forums, and social networks for our specific little area of interest within QRP or homebrewing or for our favorite rigs or vendors, but we don't come together under the larger banner of QRP any longer, in any way. I suspect that this gets us a bit locked in to our little corners of the 'net. I don't know about you, but I'm finding myself having an increasingly harder time managing all of my different communities of interest. Which tends to make me just throw my hands up and ignore large swathes of those communities at times.

This brings us to the new kid on the block: social media. The big dogs on the block are of course Facebook and Twitter, with smaller networks like Google+ also getting some play in the ham communities. I've never used Facebook for a variety of reasons, but I've been on Twitter for a few years now and did dabble in Google+ for a bit, so I can speak from experience on those two. The nice thing about the social media networks is that you do break free from that self-imposed ghetto mentioned above. Once you get a well established network, you tend to have connections to all kinds of different hams.

But that blessing can also be a curse. The reason for this is the different expectations that different hams tend to have with each other on these networks. A fair number of people expect that if you have a Twitter account with ham radio as your primary focus, you should only talk about ham radio. Likewise, I found that a number of hams on Google+ did not like it if you posted anything non-ham related to all of your "circles" ("circles" are your self-defined groupings for the people in your network). It's a fair point of view, but it isn't the one that I have subscribed to. I am person with different interests and I just don't have it in me to manage different social media accounts for each of my interests. Nor do I expect others to curate their output to cater to my desires.

The problem is that as much as I try to be tolerant of the diversity of other people's interests and ideas on the social networks, I'm not always successful. Admittedly, I unfollowed a few dozen Twitter accounts (not all hams, but definitely some) right after the last election due to either incessant gloating or whining. Probably not my finest moment, but I guess election fatigue got to me. On the flip side, while I don't think I have been a flaming partisan most of the time, I didn't leave my feed politics-free either. I have no doubt that I have annoyed my share of followers and drove them away due to my politics (especially since I'm a devotee of a political ideal that is not very popular).

My point in bringing this up is not to whine, but to contrast the social networks with the "old-school" communities such as QRP-L and web forums. It seems that you have two different extremes, neither of which lend themselves very well to the type of online QRP community which would be nice to have (at least in my view): knowledgeable, open, free-flowing, fun, and mostly on-topic but not on lockdown.

One other point I'd like to bring up that applies to all of us, regardless of what communication medium we use, is our etiquette. I'm sorry, I'm not trying to be a nanny, I know we're all grown adults. But I would also bet that the majority of us are on the left side of the bell curve when it comes to emotional intelligence (me included), which means that we are more apt to give and receive offense at times when we should not. For example, in my "career" in the QRP world, I can think of at least three different times when I've deeply offended very prominent people in the QRP world. And I can say that each time that I was notified of this offense, I was completely taken by surprise. Without getting into details, I've done and said some incredibly boneheaded things. Not because I was trying to troll the QRP stars, but just because I didn't think through the consequences of my words or actions, or didn't clearly enough communicate my intentions. Likewise, I've been wounded by the words of others, who meant no harm, but I didn't realize that until later. (We'll leave aside the issue of the intentional jerk, for whom this essay would mean nothing anyway)

All of this butthurt really damages our relations and breaks down the community, perhaps more than anything else. Again, I'm not trying to be your mommy, but I do ask that you sleep on the stridently-worded rebuttal to the post which offends you, or that you forgive the newbie question that might seem stupid or obvious. I don't know for certain, but there's a decent chance that something like this is what caused a number of our best QRPers to leave the online QRP world. Let's not shoot ourselves in the foot any longer, eh?

If, after I depart this vale, you ever remember me and have thought to please my ghost, forgive some sinner and wink your eye at some homely girl.

—H.L. Mencken

Why have I rambled on for so long about all of this? I'd like to see some of that old magic recaptured. When I designed the Willamette DC transceiver and organized the group build on the now-defunct qrp-l.org listserv, I had one of the best experiences of my ham career. I'd love to do something like that again. But I don't know where or how. I'm pretty sure that the current QRP-L would not be the place, and definitely not on a web forum like QRZ.com or eHam.com. I have the capacity to host my own forum (I could even stick it under my Etherkit forums), but it would be too insulated, as mentioned above. I have some ideas for some simpler group project builds that I'm itching to get out there, but I'm honestly at a loss of where to present them. I'd love to reach a wide audience of QRPers. Where would that be?

So if you're still around, you're probably thinking "wrap it up already!" OK, I appreciate that you had the fortitude to stick around to the end of this diatribe, so I'll get to the point. I think I've outlined an issue that needs to be addressed, but I don't have a solution. But I think I may know some elements that will be part of the solution. We need some common meeting ground like that has the same "melting pot" formula of the old QRP-L. With the withdrawal of some of our sharpest minds (and the loss of others as silent keys), we seem to be a bit adrift of leadership. The old guard is departing. Not that we need people trying to take charge and give orders. But we do need new thought leaders and innovators; people to inspire by example and by word.

I am quite fond of QRPARCI and all that they do for our community (especially QQ and FDIM), but I think it could also use a bit of a kick in the pants. A rejuvenation effort brought about via ARCI could be very effective, if done correctly. I'd hate to see it get stagnant and not take advantage of the great resource that it has: it's large number of QRPer members.

Hopefully I've given you some serious ideas to chew on, and with any luck, just might inspire one or two of you to make a positive change to help our community. I'm not one who will be any good in trying to rally others to a QRP renewal, but I hope that I can at least reach out to one who is.

Now on a much lighter note, my next blog post will be back to my normal fare! I'll give you a peek at the little group project idea that I've been working on. Who knows, maybe we can get this going somehow.

SSB In A Box

Unnamed SSB QRP Rig

For the first time in quite a while, I've taken a project from start to a complete finish in an enclosure. I wanted to have my prototype SSB QRP rig ready to take with me to Salmoncon, so I busted a move this weekend to tweak the last bits of the circuitry to my liking, build an enclosure, and get it properly mounted. You can see the results to the left. I have an assortment of Ten Tec enclosures on hand, but none of them were large enough to accommodate the bulky circuit board that I used, so I had to fabricate my own out of copper clad based on the WA4MNT instructions (such as AA7EE did with his wonderful CC-20 beta build). I would say that my mechanical construction skills are average at best, so it's not the nicest looking enclosure, but I guess it's OK for a first try (the perfectionist in me sees lots of flaws). The two-tone blue and grey doesn't look too bad from a distance. Regardless of the aesthetics, the final enclosure is quite sturdy and will work well to keep the radio safe.

SSB Rig Guts

Here to the right, you can see the insides of the radio (sorry for the crummy photo, it was taken with my phone). The mainboard is the one laying horizontally and filling most of the room in the enclosure. To the left of the mainboard is the microcontroller/DDS board, standing vertically. Crammed in right in front of that, is the 4-digit LED frequency display and all of the other controls. Unseen and in the top cover, is a 1 watt, 8 ohm speaker. The LM380 AF amplifier can easily drive it to room-filling audio.

Here are some preliminary specs so you can get some idea of the performance:

  • Tuning range: 14.000 to 14.350 MHz (DDS)
  • IF BW: 2.3 kHz (3 dB), 6 crystal ladder filter
  • Current consumption: ~150 mA RX (not optimized for current yet)
  • TX Power: ~8 watts @ +13.7 VDC
  • MDS, IP3, etc.: not measured yet, see below

I haven't measured any of the important RX specifications yet, but I'll give you some subjective operating impressions. Compared to my IC-718, the sensitivity is very close. Maybe a few dB down but not much. Noise seems pretty good, a bit better than the IC-718. A rough guess of dynamic range and intermod distortion is that it is decent as well. Haven't heard much in the way of distortion products or "crunching" in the pileups that I've tuned through. There's no AGC, so you can listen to some pretty weak DX signals, then have the local guy replying really blast through but sound relatively clean. Since the architecture is based on ADE-1 mixers and low-noise MMIC IF amplifiers, it's what you would expect. There's no preamp, but that doesn't seem to be much of a handicap on 20 meters. In fact, I think it would probably be counterproductive, especially since you probably aren't working any stations that far into the mud that you need a preamp to hear them.

As I previously alluded to, my mechanical skills are a bit suspect at times, so I needed to have a test QSO with the radio once it was all buttoned up to make sure that it was working correctly. So I did a bit of tuning around at about 9 PM local and heard K2L, the South Carolina station for the Original 13 Colonies special event station, thumping my speaker off at well over S9. He was working stations at an easy clip with fairly short exchanges, so it was perfect for a quick test. I snagged him on the first call with an honest 59 report (at least I think it was honest...I heard him giving other stations lower reports so I assume I was really a 59) with approximately 8 watts PEP into my ZS6BKW at 30 feet. Mission accomplished!

It will be fun to take this rig to Salmoncon for some camping portable operation. I've never attended a Salmoncon before, but I think any of the attendees can use the special K7S callsign, so maybe I can do some CQing on 20 meters SSB with the short call and attract some stations. We won't be up there until Friday evening, so I think we'll miss the SOTA runs, but hopefully I can also get the radio out to a SOTA peak near here when I return. It might be too ambitious, but before Salmoncon I would also like to finish a 40 meter CW rig based on my Clackamas design that I entered into the 2010 FDIM contest. We'll see if I can actually pull that off.

Stay tuned for more news on Salmoncon as it gets closer and hopefully I can get a video of the SSB rig on YouTube so that you can see it in action for yourself soon.

Two Watts Across the Pacific

I don't know exactly why, but I've had a bit of an obsession with the T32C DXpedition to Kiritimati since they got started a few weeks ago. Maybe because I found them easier to work than many of the DXpeditions that I've tried before. The fact that they are a very well-run operation has something to do with it, I'm sure. Whatever the reason, once I got a few contacts under my belt, I became driven to try to work them on all band slots practical for CW and SSB. I have a ZS6BKW antenna, so I can load it up from 10 to 80 meters. I figured 10 — 80 was a reasonable goal, but I knew the lower bands were going to be tougher since my antenna is only up at about 30 feet.

With the bands being as hot as they have been in the last month or so, it hasn't been a great challenge to fill up the band slot chart for the most part. Almost all of the QSOs made over the last few days have been snagged within one or two calls (I also thank W9KNI's book The Complete DXer for teaching me very valuable basic DXing skills). I will admit that I've been running 100 W output for these QSOs — with one important exception.

20 meters CW was one of the slots that I had not yet filled as of this morning (oddly enough, since that's THE DX band). Over the last few weekends, I've been hacking away on the firmware to the CC-Series, trying to get the last major features up and working bug-free. Thanks to a request from AA7EE, I just implemented XIT on top of the RIT that was already in the firmware (speaking of Dave, go check out his even more impressive T32C QRP story). The nice thing about XIT is that it allows you to relatively easily work split stations like DX, even though there is no "official" dual-VFO capability in the rig. Since the XIT capability seemed to be mostly working correctly, I wanted to put the CC-20 on the air to try it out and be certain. The first station that I worked today with the CC-20 was K6JSS/KL7, operated by well-known Alaskan QRPer AL7FS. It was a simplex QSO, but it was nice to bust the mini-pileup with my first call. While continuing to work on CC-20 development, I monitored the DX cluster to see when T32C would show up on 20 meters. Sure enough, I ended up seeing him pop up on the cluster at about 0200 UTC. Time to put the CC-20 to the test.

I don't have a valiant battle to describe. It took me about 10 calls to finally get him, although there weren't a lot of people calling him. I suspect that the majority of my trouble in getting him was in zero-beating him with the unpackaged encoder knob. While in RIT or XIT mode, pressing in the tune knob toggles between the TX and RX VFOs. Trying to do that quickly when it's not mounted on a chassis is tricky! Regardless, it didn't take long until I heard the sweet sound of my callsign coming back to me across the vast Pacific Ocean. Two watts spanning 3600 miles to a tropical island in the middle of a huge ocean is pretty neat. This doesn't rank in the annals of great QRP achievements, but it will always be a memorable QSO for me.

QRP ARCI Golden Jubilee

You QRP guys probably already know this, but I'm hoping that some of my non-QRP readers will check this out as well. QRP ARCI, perhaps the world's largest QRP club, is celebrating its 50th anniversary this year. As part of its golden anniversary celebrations, the organization is running a special event throughout the year. Each week, member volunteers will be activating K6JSS (callsign of QRP ARCI #1 Harry Blomquist and the current club call) from a different state in the Union, as well as DC and Puerto Rico.

ARCI will be offering some special awards in connection with the event. Rather than try to rehash them, allow me to requote the messages sent to QRP-L. First, details on certificates and QSLs from W4DU:

We recently announced that the club will mark its' 50th anniversary by
activating the club call (K6JSS) in all 50 states throughout 2011 (see
http://www.qrparci.org/content/view/8371/118/ ). A special "Worked All
States" certificate will be issued to all that qualify.  QSL cards will be
sent via SASE.  We are off to a good start as Connecticut and Hawaii were on
during the first two weeks of the year.  Currently, Georgia operators are
activating K6JSS.  Our thanks to the operators in these three states in
getting us off to a great start!  A schedule for this event along with other
helpful details is available at the link above. Here are a few items that
warrant clarification:

1.  A valid contact is considered an exchange of signal reports - QRP ARCI
numbers are not required nor are QTH/Name/etc. But we suggest RST + QRP ARCI
number or power out if not a member.

2. You can "claim" the K6JSS QRP ARCI number even if it is not exchanged.
We all will know pretty quickly, if not previously, that it is QRP ARCI #1.
If you don't know your QRP ARCI number, go to http://qrparci.org/ and click
on "Member Lookup".  Enter you call and your number will be displayed. If
you are not a member, you can exchange power out in lieu of a number.  Of
course you can also join at http://www.qrparci.org and receive a number!

3. Requests for QSLs go to the address listed at qrz.com for K6JSS. Please
send an SASE.  All requests for QSLs with an SASE will be honored.  However,
to control the costs and the work of our volunteers, we ask that you not
request a K6JSS QSL for each and every state you work during the year. Of
course if you require a QSL for an award, then we'll be happy to QSL with an
SASE of course.  Again, all requests for QSLs will be honored.  Just use
your discretion as to help us control the load.  The QSL card design is
complete; we are just tweaking it. We will not have cards to mail to you
until approximately February 1.  We will NOT be doing LoTW which we have
considered because it is very complicated for this event

4. At the end of the year, special certificates (different from the QRP All
States award) will be issued to any amateur confirming QSOs with K6JSS in 20
or more of the 50 states of the USA while running QRP. Endorsement
certificates are issued at 30, 40 and 50 states confirmed. QRP ARCI awards
do not require QSLs with the application for an award.  Just a list that you
prepare certifying that you worked the stations listed for the award and GCR
- General Class Review of 2 General Class or higher amateur friends of
yours.  You can down load the GCR form on the qrparci.org site.  This
approach will be used for the Golden Jubilee Award.

5. If you miss a few states and are desirous of getting all fifty, we will
present some opportunities at the year's end to pick up a few states that
you may have missed.  So if you find yourself getting a late start, jump in
and work what is on now.

We are encouraging K6JSS operators to work as many modes and bands as
possible.  Check QRP Spots (http://qrpspots.com/ ) often to determine who is
on.

Since I am in Georgia, I am one of the ops activating the call this week.
Two nights on 60 meters have yielded 24 contacts in 2 countries and 15
states.   Ill be trying RTTY and 17 meter SSB later in the week.

Enjoy the year!

Next, a bit on extra prizes from ARRL courtesy of W1RFI:

<snip>

I also sweetened the pot with some 2012 ARRL Handbooks to be given out
as prizes.  They will be defaced with signatures from the ARRL Lab
staff, so they will have no monetary worth, but are much like plaques
and other prizes for various on-the-air contests.

The first Handbook will go to the first person to work all 50 states, so
out of the ones that have 49 states near the end, one will be first.

Nine others will be given to the persons who work all 50 states with the
least amount of total time spent on the air, starting at 0001 Z after
each state is active. Honor system on logs and just total the time.  If
there are not enough 50-state people, we will start counting back to 49,
48. etc., with the least amount of time for each having priority.

One other Handbook will be saved for whoever works K6JSS on the largest
comibnation of bands and modes, so go get 'em on different modes.

If you miss a state, don't worry, as there will be a few ways announced
later on how you can make up the state later. It will be quite hard to
work all 50 states, especially KL7, where propagation can make QSOs
pretty tough. The ICEPAC software does a better job than VOACAP to
predict propagation at high latitudes, so when the KL7 operation is
firmed up, I will post a link to a prop chart for KL7 to the mainland
that may help the KL7 and mainland ops plan their operating.

So everybody will have a shot at a prize here if they manage a good
showing and there are certificates going to be issued for working 20 or
more states.  And although the makeup plans aren't finalized yet (sorry,
we ARCI BoD folks are all volunteers), it should easy to manage to get
credited for all 50 states.

There is a real shot that a few may manage to work all 50 states with
K6JSS and I think that would be a hoot to see a WAS award issues for
contact with one call sign!

For some stupid reason, I didn't really think about this event until the first week had passed, which was the state of Connecticut. However, I've made a 2-way QRP QSO with every state after CT, and hope to get as many more as I can this year. It would be great to get QRP WAS (I don't even have regular old WAS confirmed); which seems like a daunting task, but I really only have to successfully make one QSO a week. I'm pretty sure that I can hit most states from here with my current antenna system. One good thing going for me is the ease of contacting the states that are difficult for many other hams out east: Alaska and Hawaii. I've already bagged HI, and AK contacts are rarely a problem for me (unless the solar winds wipe out the path).

I'd like to operate K6JSS/7 for the State of Oregon, but I'm a bit leery of committing myself to that right now, given how hard it is for me to get more than a few minutes of operating time while my son naps. Hopefully, things will settle down enough to let me do a little bit of operating when the time comes.

Even if you are not a QRP op, I hope you will try to make some QSOs with the special event stations. Even if you don't work CW, there are ops that are using SSB...so you have no excuse. Check QRPSPOTS for information on where to find the current K6JSS operations.

Last Chance Hammin'

Perhaps that's a bit melodramatic, but my time for operating and homebrewing is going to be severely curtailed very soon. Baby Boy Milldrum will be arriving any day now (the estimated due date is July 22) and we're in full-blown panic mode as we finish the last minute preparations to get the baby's room ready, make sure we have all of the assorted baby stuff that's needed, and take care of those homeowner chores that need to be done for the summer. So I figured that I should take some free moments to enjoy the hobby while I can. Sometimes I feel like every blog post here should have some really meaty and meaningful content, but perhaps that inhibits me from posting more than a few times a month. So prepare for this post and many of my future posts to cater a bit more to the short attention span crowd. I'll have to get my ham radio in small doses whenever I can, so expect a bit of ADD to set into the blog for a while.

Anyway, my inbox has been blowing up with DX Sherlock alerts telling me that 6 meters has been open most evenings over the last few weeks. I finally broke down and dug out the Buddipole components on Friday so I could try to snag a few QSOs on 50 MHz. I managed to grab a few SSB QRP QSOs with the FT-817 into VE4 and VE6-land on Friday night using the Buddipole in a simple dipole configuration. The band was in great shape that night, as I could hear a lot of East Coast stations coming in quite strong via multihop Es. On Saturday, I tried to work CW QRP on 50.096 MHz but had zero success even after calling CQ many, many times. The band was open and there was still plenty of activity on the SSB portion of the band, but CW was a bust. Come on CW ops, we've got to do better than this.

I still managed to make it a interesting ham radio night. After packing in the gear from the back deck, I went into the shack, flipped on the HF rig, and checked 20 meters (just around sunset local time). Very soon I stumbled upon the legendary Martti, OH2BH calling US West Coast stations. After a quick tune-up, I was able to snag him within about 4 calls. He was absolutely booming into Beaverton (by the sounds of it, he was booming into the entire western portion of the US). This was my first QSO with Martti and was memorable to be sure.

Moving on to a more unpleasant topic, am I the only one who things that most of the ham mailing lists are dying of a creeping mediocrity and groupthink mentality? The big two QRP-Ls are mostly a joke as far as getting an interesting, topical discussion going. On the other hand, start bitching about computers or some other off-topic old fart rant, and you'll get 30 messages a day. The SKCC group made me sick with its virtual pitchforks-and-torches assault on the new owner of Vibroplex because he had the audacity to replace the stamped brass identification plates with a silkscreened version. The way that a few prominent members of that group (including one who is affiliated with a competing key manufacturer I might add) character assassinated the owner was quite disgusting.

This provides a nice segue into another topic people love to hate: Twitter. I quit tweeting a few months ago due to the large jackass/decent person ratio that I was experiencing. I thought I would miss it quite a bit, but once I got over the DTs in a few days I didn't really miss it much at all. I still debate whether I should go active on Twitter again, because I see some utility in it; but even when you remove the jerk factor, it still feels like drinking from a firehose most of the time. Not to mention that huge time sink that results from checking your account all of the time make sure you are up-to-the-minute on the latest crap. What to do?

Finally, a plea. Some of you may know of qrpedia.com, which I tried (and failed miserably) to turn into a QRP/homebrewer aggregated blog and knowledge repository. It's already in sad shape, but with the new kid coming, I know I'll have no time to devote to it, so I need to let it go. I don't want to nuke the site because there are a handful of people who put a lot of hard work into posting content there. I would like to sell the site for a nominal price and have it go to someone who could give it another chance. Please contact me if this interests you at all. Prices and terms are very negotiable.

Dayton/FDIM 2010 - Days 2 and 3

Hans Summers Presenting at FDIM 2010

Please accept my apologies for the long delay in posting my impressions of Hamvention and FDIM. I was literally on the move every waking hour of my time in Dayton on Thursday, Friday, Saturday, and Sunday. Up about 6 AM to shower, at Hamvention all day, then FDIM at night. Back to N8ZM's house around 11 PM to crash in the easy chair. I've never worked so hard to have fun. My writeup is going to focus mostly on FDIM, since that was the main reason that I was in Dayton. I probably can't give you much information about Hamvention that you haven't already heard thousands of times from other hams. Besides, the muse has taken leave from me again, so I don't want to butcher this recap any more than is necessary.

My adventure in Dayton got off to a proper start on Thursday, which was seminar day at FDIM in Fairborn. I arrived around 7 AM, which was a bit early, but I got a chance to get a seat pretty close to the front of the room. By the start of festivities at 8 AM, the room was pretty much full. There had to be more than 200 attendees (I unofficially heard that this was the best attendance at FDIM in a few years).

There were a total of six presentations for the day. I'll give you a brief rundown of my impressions of each one.

  • K8ZT - The morning started off with a presentation by Anthony Luscre, K8ZT about strategies for being successfull in QRP contesting. The PowerPoint deck for this talk came in a over 140 slides, which meant that Anthony had to rip though the slides at a lightning pace. He gave some good inspiration to those of us who have not yet taken the QRP contesting plunge.
  • G0UPL - Next up was world-class homebrewer Hans Summers, G0UPL. His presentation was about his QRSS efforts. About half of his talk covered information that is already on his website, but he did get into some areas that I haven't seen him cover before. I especially enjoyed seeing his natural power battery experiments. At the end of his talk he announced the sale of a kit version of his latest QRSS transmitter, which I'll cover later on. He came with the stereotypical dry British humour (LOL), which I enjoyed immensely.
  • G3RJV - My favorite talk of the day was given by the legendary Rev. George Dobbs, G3RJV. He did a masterful job of combining a grand tour of simple receiver designs with more philosophical aspects of our hobby. You can tell that Rev. Dobbs has honed his public speaking skills quite well from his years in church.
  • NE1RD - After lunch break we were treated to a great talk by B. Scott Andersen, NE1RD on the topic of his 100 Pound DXpedition. While the 100 Pound DXpedition is not a QRP-specific topic, NE1RD put a QRP spin on the talk by focusing on his recent CQ WPX QRP efforts on St. Thomas.
  • K8IKE & K4ZLE - Jim Everly, K8IKE, and Jay Slough, K4ZLE brought a power-packed presentation about  acquiring a set of "good enough" test gear for the homebrewer and how to use this gear to perform a useful subset of the ARRL lab procedures for RX and TX performance. We also had a bit of good-natured sarcastic side commentary from Ed Hare, W1RFI from the League's lab. This was extremely useful stuff and I wish that they had a little more time to delve into this topic.
  • K9AY - The final talk of the day was from prolific FDIM speaker Gary Breed, K9AY. He covered low band QRP operating; mostly focusing on the challenges of deploying a useful DX antenna on these bands. Gary brought some good information, but unfortunately he had to compress the end of his speech quite a bit because he ran long in the first half. Fortunately, the proceedings had all of the information that was skimmed over.
FDIM 2010 Thursday Vendor Night

FDIM 2010 Thursday Vendor Night

After a long day of sitting and listening to speakers all day long, we had a few hours to get up, grab some dinner, and stretch our legs. By 8:00, the main ballroom was reconfigured for QRP vendor night. The room was not 100% filled with vendors (as you can see in the photo to the right, most of the tables in the middle of the room were empty), but there was still quite a bit to see. Hendricks QRP Kits had the largest display, but Diz from kitsandparts.com was probably a close second with his huge stock of 'roids, components, and RF Toolkits. As I mentioned earlier, Hans Summers announced the sale of his latest QRSS transmitter as a kit with a PCB and a microcontroller that he would custom program with your callsign. This was the most popular item of the night. For nearly the entire two hours of Vendor Night, there was a large line of people waiting to purchase a kit and have it customized by G0UPL. I hope this sparks a lot more QRSS activity here in the States.

K3PG Sonic Tray Chassis Willamette

K3PG Sonic Tray Chassis Willamette

One very neat aspect of the night was getting to meet a bunch of the QRPers that I've known for years via the mailing lists but have never seen in person. Some of the highlights that stand out for me were my introductions to WA0ITP, K3PG, K8IQY, NM0S, KC2UHB, W8DIZ, and WB8ICN (sorry if I missed anyone!). It was a pleasure to finally be able to shake hands with my peers and mentors. I'd like to give a special shout-out to Diz for his salty greeting! That's the way to make a guy feel like a part of the gang from the first minute! I loved it! It was also a treat to have a good, long conversation with K3PG, whose enthusiasm for the Willamette was truly humbling, as well as infectious. Chatting with WA0ITP seemed like two old friends talking. I've collaborated with him so much via e-mail that it seemed perfectly natural to pick up where the electronic communications left off.

I hate playing favorites, but I think the true highlight of the night was meeting Mikey, WB8ICN. I was sitting in the lobby of the Holiday Inn, working on my laptop and waiting for the Vendor Night festivities to start. I wasn't paying much attention when a couple set down in the chairs opposite from me. They were having a lively conversation for quite a while, but I was engrossed in reading the FDIM Proceedings CD that I purchased earlier in the day. After a while, the gentleman sitting there was getting more and more animated in his conversation. At that point, my curiosity got the best of me so I had to check out what was going on. Something seemed vaguely familiar, but it took me a few moments before I saw the shirt with "WB8ICN" embroidered on the chest. Of course, I got up and introduced myself to Mikey and his wife Marybeth, which seemed to take him by surprise a bit! We had an awesome conversation and were probably getting a bit louder than we should have been. That was the only time we got to talk at Dayton and I wish I had more time to BS.

I'm only going to skim over Friday, since it was a bust regarding FDIM. Hamvention was as large and as crazy as everyone had said it would be, especially the flea market. Sometimes I get a bit overwhelmed in such huge venues, so I wasn't really acclimated to what was going on until Saturday. I imagine that I looked like a lost puppy dog wandering around. Hara is pretty old and decrepit, but that certainly didn't slow down any of the activity. The only thing that was really "offensive" to me about the place was the bathrooms. I never used them at Hara, but just walking within 30 feet of the entrance was enough to make me want to gag. I think I still have nightmares about the smell alone. God help anyone who actually had to use them

Due to a bit of a communication error on my part, I didn't make it to Friday's FDIM activities until the event was almost over for the night. So I'll just skip right on past that and get to the good stuff about the Saturday night banquet in my next post.

The Clackamas QRP Transceiver

Clackamas Schematic

Since FDIM 2010 is in the history books, it is my pleasure to finally publicly release my entry into the FDIM 2010 QRP Challenge: The Clackamas 40 Meter Transceiver.

The rig is a VXO-tuned superhet that operates around 7.030 MHz. The heart of the design is the BF998 dual-gate MOSFET (which was popularized by W7ZOI on his website and in EMRFD). The BF998 is used as the front-end mixer and as a combination product detector/BFO. My new favorite AF amp, the TDA7052, is my choice for the single allowed IC. The VXO signal is mixed with a carrier oscillator in a JFET mixer, which is then bandpass filtered and fed to a BS170 power amplifier.

Please download my contest writeup for full details of the design. I'll dissect the design in further detail in future posts.

More Willamette Pix

I recently received a couple of excellent photos of completed Willamette transceivers, and I just can't help but brag on these wonderful creations.

W8BH Willamette with Digital Dial

W8BH completed his rig quite a while ago but recently upgraded it by adding a KD1JV digital dial. Looks very sharp, Bruce!

K3PG Willamette in Sonic Tray Chassis

I'm really getting a kick out of this one. K3PG, appropriated an old Sonic drive-in tray to create a chassis for his Willamette. I really enjoy seeing the more mechanically inclined hams build cool enclosures out of interesting scraps. He did a great job with the shielding between the VFO and mainboard. FB work Paul!
