No earth-shattering news to report on the blog, but a few little things to mention (hence the "junkbox" title). The CC-20 Beta 1 test is proceeding pretty much as planned. As of tonight, AA7EE has his receiver up and running now and a couple of the others are close behind. I'm eagerly awaiting the results [...]
I'll admit there were times when I thought I might never get this thing working, but dogged persistence in the face of frustration will sometimes get the job done. Failure to accept the mushy and hum-ridden audio finally led me to crack the tough nut. Today, I finally slew the new CC-20 beta dragon. Without getting into [...]
As I've previously noted, the VRX-1 is a nifty little basic direct conversion receiver, but it has some shortcomings that could be problematic under certain circumstances. Here's a story of one of those issues and the cure that was found. Dave AA7EE purchased and built a VRX-1 kit a while ago but was never fully [...]
Update Here's a quote from Wes describing the equipment that he was using on his end: I hope that my signal was OK when we worked. I was in the midst of wrapping up a frequency synthesizer project and had it running on the rig for the first time. When I heard you [...]

As you can imagine, between having a near-toddler cruising around the house, doing a major redesign of a QRP transceiver, and trying to bootstrap a new small business, free time is at a premium (and my wife and kid owns what little there [...]
As you may recall in a previous post last December, I made a QSO with, then received a cool e-mail from Bob KE7GKM about his quest to make 100 QSOs using a lashup of a VRX-1 and a homebrew QRP transmitter. Bob kindly sent me an update on his progress: Hi Jason, This is just [...]
Things have been a bit quiet on the blog front as I work to get the CC-40 beta up and running. Last month, I had an initial set of beta PCBs manufactured, but I made a really big mistake. Somehow I bungled the footprint of the ATmega168 microcontroller, and it ended up much smaller than [...]
I'm pleased to announce that I've filed the appropriate paperwork, and that my new open source amateur radio company is born! The logo links to the new domain, but there's nothing on the web yet. I've also given "Project X" a proper name. It's now going to be known as the CC-series of transceivers (with [...]
