Tenner – a 500mW CW transceiver for 10m
This was a rig I built and used a few years ago for 10m CW. As you can see, the design is simple but it worked across the Atlantic many times. Pull the crystal too much and the RX-TX offset becomes too great. Ideal as a simple rig for 10m CW.
CW transceiver by 10 m, from L1 to L5 which wire diameter it takes (and SBL1 DBM) what is a filter for the CW from many Hz or KHz, for audio output HI-Z and a piezoelectric
This seems to be a cheep but good little circuit for cw
