Lesser Chirpy

When I was fitter, I enjoyed designing and building. Sadly this is much harder now. Like all of my circuits, I am sure they can be improved. I make no claims for originality and take inspiration from many sources. My wish is that you use my circuits as the starting point for your own ideas. 

Looking back many years, I designed the Lesser Chirpy for 10m CW. Originally I started with the Chirpy, but it chirped too much! The Lesser Chirpy more or less stopped the chirp. This was a "for fun" rig. It does work, but I was concerned about calling CQ over weaker stations as the RX sensitivity was not as good as modern rigs. My recommendation is ensure that calls are not made over other stations. Fine to call others, but be very mindful of other stations.

The original name was the XBM10-2, but Lesser Chirpy was more meaningful!
