Spike on 120.000 mHz
Posted: Tue Feb 13, 2018 7:59 pm
Not a real problem, but just curiosity really.
On both SDR's that I'm currently using - An SDRplay RSP2 and a Chinese RTL, there is a permanent , strong carrier centered on 120.000 mHz.
I'm getting old, but am I remebering correctly that this was produced internally on "old-fashioned" receivers as well? - or m I, as they say "just blowing smoke?"
This may well seem a stipod question, but did it have something to do with the local oscilator?
Another display of ignorance...
