I have a similar issue. Rig is on, Amp is on, all good, been working fine. Shut off Amp, rx signals drop drastically. Amp still off, key exciter, 10 watts or so, just a 'dit' is enough, sigs pick back up in receiver, all normal. Not a 'show stopper", but curious why it is happening. Amp is a month old and other than this, working fine, working fine. Never been run above 1 kw out. Bob - K2RU

There is still the ambient hiss from the K3 speaker." Isn't that exactly what you would expect to hear if the amplifier was spuriously keyed but the K3 was not keyed? All it would take is a faulty keying cable.
