Hi,
After increasing my vast knowledge with study, I am ready to up my game and reattempt some AM and FM receiver circuits. This time, on PTH protoboard for noise reduction.
I have scoured the internet for circuits and have tried many of them on the breadboard. I don't have any of the special components radio circuits call for such as ferrite bead inductors, so I have had limited success.
I am asking the community for circuits they have tried that are:
1) Relatively simple in concept
2) Modest component count as soldering together a big circuit takes considerable skill and troubleshooting ability
The primary issues I had with the (regenerative) receivers I tried was:
- frequency drift
- significant noise as volume is increased, unable to increase gain beyond some limit
I'm willing to shop for specialized components as well as, if I know what I'm looking for, salvage from old radio equipment as people are always giving stuff away around here on the local classifieds.
Thanks for your time and please do not suggest to Google circuits otherwise I'll be forced to throw my multimeter at you.
Regards,
Mark
