John,
it is the same with all transceivers. In standby everything is OK and
input power is shown on the KPA screen. But in operating mode the signal
blocks somewhere. The RF of the TS590S doesn 't even switch the band
filters of the KPA while it does switch them in standby mode. I suspect
the input relay or circuit. There may have been DC in the coax line
caused by a remote beverage switch.
The amp shows 0.5 Ampere current when PTT is applied. Not very much so
there may be more trouble.
CU all in the PACC, starting within a few hours!

Are you using a K3(s)? Are you sure the rig isn't switched to ANT2 by
mistake?

Hi,
since this afternoon my KPA500 has a very high input SWR on all
bands and there is no output. What might be the problem? I can 't
find the schematics.
