Aloha All,
I have a Ameritron AL-572 that goes instantly into Transmit as soon as I
turn it to Operate and the LED lights up But there is no output and no RX
Input SWR is Very High and the relay is fine. I need to turn off the amp to
get RX back. Any suguestions?
Thanks
Roland AH6RR

Aloha all thanks for the reply's I found the problem it was a diode that
is in the keying line and it was shorted. It did not matter if there was
anything plugged into the Rely jack it would key. Replaced dioed and it is
working fine now.

Yes, Virginia, there certainly was a Hunter
"Bandit" sold to hams. I saw one, but
never operated one. It was a bargain
in its day--- based on price, anyway.

I have used them in many hf, vhf, and 432 amps for years. Just buy the
correct ones.
