I want to build a simple 40 meter CW transmitter and Receiver pair. What should I do to get started into home-brew HF RF devices?

  • $\begingroup$ Are you looking for suggestions on how to find a ready-made kit, or are you looking for suggestions on how to get started making your own from scratch? $\endgroup$

I built a BitX 20a, which was fairly complex, but a really neat kit. If your soldering skills are ok, and you can wind small wire through tiny donut shaped cores, you will have a lot of fun.

The SMK-2 40m kit might meet your needs (40 meter CW), but it's surface mount. Don't be afraid of that, with a good magnifying glass, and some inexpensive chinese made soldering tools and some solder paste, it's easy.

I also built a Sudden Storm from KF5OBS. They have several simpler, small kits that might be a good fit.

I've found kits a great way to learn. I learned a lot trying to get my BitX to work, I found a few errors I made, but I learned a lot about the theory in the process. Don't be afraid to learn as you go!
