A 40 meter SSB QRP transceiver

 

"This transceiver was conceived as a power-efficient, small, lighweight unit to be carried in the backpack, along with antenna and battery, for use during trekking and mountaineering trips. It had to be reasonably rugged and reliable, and perform well. Furthermore, I wanted it to solve all the problems the old DSB transceivers had, such as frequency instability, distorted modulation, lack of sensitivity and selectivity, and others."
