Simple 80m rig (not tested on-air yet)

This is the schematic of a little experimental 80m CW transceiver. It puts out about 60mW and is only moderately sensitive, although I have not managed to accurately measure it yet. Offset between RX and TX is about 400Hz but more can be obtained by closing S1. It should be used with a low pass filter really.
