[Elecraft] Solution to KPA500 Problem

[Jim Rhodes]

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

Hi Ora...

I'm confused. You say you removed the tuner and connected the amp directly
to the transceiver?

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. :)
