Hank,
I fail to see why he would have to worry about the Ameritron amps,
since they (Al-1200, AL-1500, AL-80B at least) only have 12 VDC on the
relay jack, and require sinking 100ma max. The specs listed for the
K2 say 1A and 200V. Am I missing something??
Thanks,
Don, WB5HAK
The K2/100 can handle the voltage/current requirements ..... But he
relay in the Ameritron amps is not the fastest relay to pick -- it
takes at least 50ms or more.
During that time the K2/100 sees a high SWR during this time and shuts
down the amp, so you start sending and the amp has no output - and you
never know if you aren't watching the meters. K6XX has a "relay
accelerator" circuit on his web site that works great in speeding up the
relay - my AL-1200 with this circuit built on a terminal strip has not
failed since I put it in place.
Doesn't happen with other radios and the Ameritron amps .... Just the
K2/100's.
