Buy a low reading watt meter.
Using a foot switch can make hot switching possible, If you get out of sync.
I normally blame it on the alcohol.
Well I have thoroughly examined inside the Amplifier . . . and there is no sign of anything having arced over.
Also checked the resistors that feed the bias voltage around the zener, and they're spot on. Can't see any faulty components anywhere either.
So, I'm just thinking this loud bang may have been the safety spark gap arcing . . .
Anyway, I have cleaned the relays, in case that was the cause of the problem . . . and will start using it again, watching everything carefully !
Not possible, as the footswitch switches both the Transceiver and the Amplifier to transmit !
The footswitch could be suspect. Loose connections, or something?
Or, the footswitch could have been drunk.
I recommend a Linemaster 636-S dual stage switch. Completely drunk proof.
Well, if it keeps happening, you could pretend it's 100 years ago and just operate "spark."
No need for filters in the receiver, the signals are everywhere.
Is that spoken as a true drunk, or just a pretender?
I don't think I'm a true drunk but I do like good scotch....and beer...and wine.
The key is no drinkin' before 5:
