[Elecraft] KPA500 attenutes TS2000 receive.

[Jerry]

Thanks for the help in this solution. That was exactly the problem. I have
disconnected my Ameritron Model ARB-704 from the KPA500 and substituted it
with a homemade connector using the remote connector pins 2 & 4. Before this
TS-2000 was pushed into duty as the replacement for the ailing K3, it was
being used as a MARS station connected to  Collins 30L1 amp which exhibits a
high negative voltage (-120VCD) for the keying circuit, hence the Ameritron.


 

Jerry's world is now at peace!

 

Best regards,
