Of course, I love it. MOSFETS! NE602's! 10.7 Mc IF cans! Cycles, not hertz! And a Tayloe Quadrature Sampling Detector made from junkbox parts from the Reagan administration. FB Keith. And the frequency display is icing on the cake.
I thought the group might find my new Franken-SDR interesting.
It is an SDR with a superhet front end.
I wanted to play with an SDR but I didn't want to get a kit or buy
parts, so I scrounged through he drawers and found a mux chip
cd-4016 circa-1980 some old 7400 logic that is probably per-1980.
This could make a QSD but only very low frequencies. Well I thought
how about at IF frequencies?
The frontend is a MOSFET mixer (1975) , the 10.7 IF is a dual gate MOSFET
(1975), the second mixer is a NE602, the IF cans are all stagger tuned to
give a bandwidth of 50kcs.
The only thing modern is the DDS but I old-time-ifyed it with BCD switches.
VK6FTH did something similar: http://www.vk6fh.com/vk6fh/SDRradio.htm
