K8IQY SS-40 Stable and Sensitive 40M Receiver The SS-40 high performance receiver is the latest design effort from Jim Kortge, K8IQY. SS stands for "Stable and Sensitive". It exhibits the signature IQY extremely quiet amplifier chain. Disconnect the antenna and the receiver's noise floor is almost undetectable. A matched crystal IF filter provides a steep sided 500 cycle bandpass and outstanding opposite sideband rejection. Covering the 40M QRP "watering holes", a Super VXO provides 25-30 kHZ of smooth stable tuning, with NO PERCEPTIBLE DRIFT, even from a cold start! (Available now)
NMØS Ham Can Minimalist Regen Transceiver The HAM CAN Transceiver is the latest offering in minimalist amateur radio from the Four State QRP Group! The HAM CAN is a crystal-controlled CW transceiver, delivering 1/2 to 1W transmit power, with enough sensitivity and selectivity to receive plenty of signals. It does all this with only TWO transistors! This kit is not difficult to build. All parts are thru hole parts, there are NO SMT parts, and all connectors are board mounted which eliminates point to point wiring. After all the parts are installed it's ready to try out.
