I was looking for ideas for super-regenerative receivers and I came across this website showing a circuit similar to mine:
http://jap.hu/electronic/sregrcvr.html
I attached the circuit for reference.
I accidently forgot to include a low-pass filter in my circuit, but this circuit has one (via R3 and C6). I used the calculator at http://sim.okawa-denshi.jp/en/CRtool.php and it states the cut-off frequency is about 1Khz.
Why is 1Khz chosen? If I wanted to receive audio on this thing, wouldn't 1Khz cut most of the wanted sounds instead of the super low deep voices? I don't get it? and if I wanted to receive data, wouldn't 1Khz cut-off affect data transmission speed?
