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

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.
