KPA500/KAT500 with Icom ic-7300

[shfoster]

Has anyone successfully run this combination? I have tried rf sensing
and get a fault on the amp,or the tuner locks up.  tried using the Icom
band data to the amp, using the elecraft aux cable between the tuner and
the amp, and any combination of the above. It appears not to be mode
dependant. I am driving the icom with 30% power. The power level does
not appear to matter. The tuner/amp combination has been working
successfully with my previous radio (brand Y).  There appears to me to
be an issue of the amp keying at the same time the tuner is switching
bands.
Both amp And tuner have latest firmware. Cables are from the elecraft
manuals, or Elecraft.
  Any help greatly appreciated.

A little more background....   with the Rf sensing the problem only presented itself when a band change required the tuner to change antennas.  so during a very quick keydown on the new band the amp keys before the tuner switches antennas and therefore faults due to high SWR.  if im not mistaken the PTT line between the tuner and amp stays high during a tune but not during an antenna change?  otherwise the amp would not key until the tuner changed antennas.

Hi,

You need the keying line to go from the Icom first to the tuner and then back to the amplifier.

Cheers,
