[Elecraft] KPA500/KAT500 with Icom ic-7300

[ab7r]

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.

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.
