[Elecraft] Kpa500 not playing with my IC-7600

[Tom Ewing]

Good day, and thanks for reading. 

My newly acquired KPA500 doesn’t want to play with my IC-7600. 

In operate mode when I key the radio, the LEDs on the KPA500 display solid into the yellow, and there is no output. The amp is not faulting. 

I’m using an Icom 7 pin DIN cable (two actually from two different vendors) and tried two different radios, both IC-7600s with the same result. 

In the KPA menus, I have set the “radio” option to “analog”. 

Am I missing something else?

Thanks in advance.
