I think he means the control cable. KAT500 comes before KPA500 there and three tunes has the ability to interpret PTT to the amp.

My transceiver is connected directly to the amp at all times. The tuner is between the antenna and the amp. Removing the tuner would connect the antenna directly to the amp (ok if a good, resonant antenna I think). The tuner should not be placed between the transceiver and the amp. Did I misread your post maybe? In my mind, it is still very early in the morning. :) 73, Kev K4VD On Mon, May 1, 2017 at 10:47 AM, Ora Smith <[email protected]> wrote: > I recently encountered an odd problem which I thought I would share in > case anyone else experiences it.
