Hi guys,
I have given up trying to use an SDR to feed my scanner. I have reverted to the "normal" method of using a scanner and a USB soundcard dongle. The problem I am struggling with now is noise when there is no traffic. There is a constant hum. I have tried installing ferrites and a ground loop isolator, but no change. The USB dongle is very basic, with just a mic input and headphone output. No line-in. There are no settings in alsamixer that I can adjust, such as turning off ACG. Does anyone have any ideas?
Walled Lake and Commerce Township Fire Dispatch Live Audio Feed is my feed to hear for yourself.
Thanks!
Mike
