I am cuurently working on an all-band all-digital HF receiver. It uses 150
CK-722 transistors to make a home-brew DDS LO, and another 275 CK-722, 33
1N34A, and a flourescent digital readout from an old DMM as the control
logic. Direct frequency entry can be input from a rotary phone dial. I was
messing with the 2N21, but found that the beta was a little low at 10
The audio driver is a 2N107, 2N170 push-pull pair. I know it's more modern,
but I was trying to keep at the leading edge. Sounds real good when driving
an Edison speaker.
I can bring it to tacos, but someone else will have to bring the 24V @ 50amp
battery. Two car batteries will do.
