Tenner 10m CW transceiver

Click for bigger image.

The Tenner is a very simple CW rig for 10m. It produces about 500mW output and has worked across the Atlantic on many occasions. Offset RX-TX seems to work out at about right, although no special circuitry is employed. This simple circuit just works. Although I used an “at hand” SBL1, any double balanced mixer is likely to be OK. Although I did not try it, a homebrew DBM would be fine.
