I started having trouble with stations not being able to decode my Olivia transmissions using FLdigi
and the VAC409 cables. Thetis version 2.9.0.6
Lands up my signal is not clean. It has another low freq audio signal superimposed on it. Looks like 60 hz hum possibly.
Is it possible at all that 60 cy hum could get onto the signal due to a ground loop in the AC wiring- in the shack?
I've tried all the obvious things to no avail. Anyone ever see this?
