Hhhmmm... I'm coming late to this thread, as I wasn't paying attention before.
Please forgive me if I have missed something but - I have, in the past, used both a K3S AND an old Yaesu FT-101ZD with my KPA/KAT 500 power combo. I *THINK* that is similar to what Jim is trying to do. Here is what I found, if it helps. When the K3S is on, it communicates with the KAT/KPA. However, when it is turned off, it leaves the KPA/KAT in a state where they are not prepared to accept input. I forget the specifics, because I have since provided the 101ZD with it's own amp. Try this - Turn off the K3S. Turn off the KPA. Turn the KPA back on, with the other radio connected to the RF input and at least an RCA keyline connected for the PTT. See if it works. IIRC, this was what I had to do. If anyone needs the specifics as to WHY it works that way, I can try to dig out the old emails with Elecraft. And, it's been a while so I may be mis-remembering the details. But, I know it worked. I hope this helps... 73 de Chuck, WS1L chandler...@gmail.com On Fri, Apr 1, 2022 at 11:01 AM James Bennett via Elecraft < elecraft@mailman.qth.net> wrote: > Well, it looks like there is no simple solution to this dilemma.
