[Elecraft] Strange Occurences

[wayne burdick]

Morris,

An LM380N-8 is a darn rugged part, so I'd look elsewhere. Next time 
this happens, I'd suggest opening up the case and taking some DC 
voltage readings to help isolate the problem. If just touching the case 
causes it, the likely culprit is a loose connection, possibly 
associated with a CMOS control line or the gate of a JFET.

Also make sure you don't have squelch turned on (in the secondary menu).


I'm sure Gary would have additional suggestions.

73,
