[R-390] Newbie needs help

[Norman Ryan]

Hi, Mike,

Try reconnecting the 40' antenna and tune in a signal that distorts as you mentioned earlier.  Then switch FUNCTION to MGC and gradually reduce RF GAIN to where distortion clears up.  If it does, I'd suspect a leaky cap in the AGC circuit.  It doesn't take very much leakage to throw the AGC off kilter.

The R-390 AGC is very robust, and thus very difficult to overload with strong signals.

Best of luck and keep us posted,
Norman, KG4SWM
