[Elecraft] KAT500/KPA500 with Icom 7600 accessory cable

[Ken B]

Thank you Don.  The pin 3 (send) did the trick perfectly. Now it works at 300 to 400 watts out with 20 in. The problem i have now is when i switch bands the kat will not tune unless i remove all AC power from the amp.

Look at your Icom 7600 documentation.  I believe the 'keyword' may be 
"Send" or Keyout or something of that nature (PTT should be an input to 
the transceiver, not an output, but some manufacturers mix them up 
causing confusion - check the documentation).
Connect that output from your transceiver first to the KAT500 AMP KEY 
connector and from the other KAT500 AMP KEY connector to the KPA500.
That allows the KAT500 to disable the amplifier keying if the KAT500 
needs to tune.

You should then be "good to go" with the basic cabling.  When you get 
the proper cable, it will integrate better with your Icom, but the basic 
cabling will get you on the air with your new toys.
