[Elecraft] KXPA100 Antenna Switching

[Dick Dievendorff]

Tap of the TUNE button should start tuning, and the 25 watt LED should blink during tune.  

Another tap while tuning should cancel tuning, and the 25 watt LED should stop blinking.

ANT change is a Hold of the same button.

Antenna change requests (button hold or KXPA Utility) should be ignored while tuning or transmitting.

When I press and hold the Tune (ANT) button, the amp typically sounds as if a relay is chattering and the LED under 25 flashes. Almost like it doesn't recognize the switch command and attempts to go into the tune mode. Regardless of what it is doing, the antenna switching does not take place. I've also tried to switch using the KXPA utility and it will not make the switch either when the amp is acting like this. Now sometimes the switching will all function correctly from the button or utility.
