I will fully admit that one of my annoying weaknesses is the intention to take on far too many tasks than I can reasonably handle. Right now I'm knee-deep on trying to make the final revisions to my CC-Series design so that I can get it to market (only about a year late). It's very cool that your daughter is interested in the Code and it would be great to take advantage of that interest. I wish I had some instructions to help you. I can't promise anything, but I'll see if I can't squeeze in some time to write up a simple bit of documentation for the oscillator. If you decide to try to tackle it before I can write up docs, please feel free to ask for help any time you might need it. Thanks and good luck! Jason NT7S Hi Jim,

Just wondering...I was a ham 35 years ago...made it to general class...but have been out of it since then. My 8 year old daughter and I just finished reading a kids spy novel that included morse code as part of the setting. She's very keen to learn. I have my fathers key from when he was a kid as a family heirloom of sorts...would love to build this design for my daughter to use in learning code. I could probably pull it off just from the diagram, but if you have any instructions would be most appreciated. Many thanks for posting it! jim did you get around to creating the instruction kit?

Glad you like it! It's true that nothing beats a clean sine wave sidetone, especially when compared to some of the near square wave tones you see on the simpler CW kits. Thanks for being a reader and bookmarking the blog! 73, Jason NT7S @Tom Dean K7TPD

Added an op amp circuit (LM386) and an 8 ohm speaker, assembled into a nice plastic case and it sounds amazing. I'm gonna turn down the sidetone on my HF rig and keyers and use this thing exclusivley. I turned the trimmer pot (of the twin-t circuit) way down and I use the op amp circuit to adjust the volume.

I just built this circuit last night and was very very pleased! I am gonna add an amp circuit tonight, probably using an LM386 or equivilant. and put it in a nice case with a quality speaker, can't wait to hear it's sound when that is complete. Thank you very much for posting, I have your site bookmarked! 73, Tom K7TPD I have been a CW op for 32 years and I am very picky about the quality of sidetone.

I'm really happy to hear about you and your grandson working together to get your Tech licences. Even better that you guys are going to learn code! It's encouraging that there are still folks who want to do it the "old-fashioned" way. Check back in when you get your licences and also let me know if you build the CPO and if it helps you at all. One of the thinks I hope to do with my new company is to come out with a kit or two for the beginner such as you and your grandson. Check back in a half-year or so and hopefully I'll have something out by then. 73, Jason NT7S @Robert Mendel

I have a renewed interest in electronics from days of old and intend to share this intrest with my grandson so I thought we'd get our tech lic. together and even learn code together.(like the original hams did it :>). Please make sure I have access to your data base I see a wealth of knowledge there and I'd enjoy shareing it with my grandson. Your site popped up when I googled: practice code oscillator.

Thanks, would greatly appreciate it. Hey, a little rusty on my manhattan construction could you possibly send me a step by step construction. Thanks, would greatly appreciate it.
