[SignalOne] Anyone on this list?

[ni6q at aol.com]

Hello, Folks

I am new to this list. I have a question about the CX7A.? The speaker produces an annoying hum only when in transmit.. (but none in receive.)? The 34 Volt supply is fine.? looks like some inductive coupling.? Anyon had this problem?

Also, the IF shift drifts over an hour and the zero is between 10 o'clock at startup to 1 o'clock after a couple of hours..

Any info will be valuable.

Thanks,

Brian,? NI6Q.
