I have the same problem with some of our local 2m repeaters -- even when
I enable the 10-band rx equalizer and minimize everything from 250Hz down.

There is a 300 Hz High pass filter in the audio path. Tones below 150 Hz
should be attenuated
by over 40 dB.
Where are you getting the audio from? Are you using the audio output jack
on the radio?

Hi Graham,
Thank you for the speedy reply. My Neighbor and I have tried all sorts of
AGC settings to no avail as far as the hum is concerned.
If we turn off the tone the hum goes away and audio is fine. My repeater
sends out 127.3 at about 350 Hz level for PL most receivers of course strip
it off
so you don't hear it.
If we go to simplex on 6 FM and use the tone the hum is there, turn off the
tone and hum is gone. Playing with AGC settings has
not even reduced the hum as long as a tone is present.
My humble thought is the low end needs to be filtered out then all will be
well.
