Hello Power People,
I have an Alpha 86 where something has failed resulting in a fault.
Since this failure mode began very shortly after the amp received the
newer and stouter PIN diodes, and the amp was not subjected to
excessive abuse, I believe the control circuitry itself may be wonky.
I would like to take my chances, bypass the internal TR circuitry and
also the control circuitry, and use an external TR switch I have on
the shelf (Ameritron QSK-5).
Unfortunately 100% of the time at the first dit the control circuitry
bounces the amp out of transmit mode rendering it unusable. I would
like it to stop doing that. I fully understand the risks and am
willing to take them.
Suggestions?
