[Premium-Rx] Cubic R-2411 (aka 3030A) Low receive volume

[Tim Kass]

I have several of this fine units, today the left receiver volume dropped significantly to a very low level, could still hear signals, etc... checked modules, no fault lights lit .. was wondering perhaps since I was driving a small  8 ohm speaker with it and since its 600 ohms.. could the mismatch have caused some stress on the audio circuits ... any ideas would be greatly appreciated.. have not started swapping out modules as yet.. 73,  Tim K8WBL
