Yet again, I am indebted to Steve G1KQH for the following:

Lesser Chirpy - a VERY simple 10m transceiver

This design is a couple of years old and evolved from Chirpy. Unlike the original design, chirp on 10m is negligible. This design really works and gives credible results on 10m with just a handful of parts. Sensitivity could be better  with a few more parts, but not this simple!
