[Elecraft] KAT500 set up

[Mike Baird]

Just received my KAT500 and got it all hooked up.  Works perfect with my K3
and KPA500.  However, when I try to use it with other radios on the desk,  I
have a problem.  All works OK when the amp isn't inline.  But, when using
another radio (other than the K3), and you put the amp in the operate
position, I get almost a muting of the RX.  This is before actually keying
the amp with my footswitch.  I've fiddled with the keying cables with no
success.  Didn't have any trouble when using the previous tuner (Palstar).
I must be missing something rather obvious.

 

Thanks for any help.
