[Elecraft] 2nd RX antenna switching

[Torsten Clay]

Is it possible to make the 2nd RX option switched by a SINGLE button
press?

1) is it possible (in principle) with a firmware change?

2) How about this: re-route the relay line for the ANT1/2 function to
the 2nd RX relay, and somehow fool the K2 into thinking the antenna
tuner option is installed? 

3) Could I buy the internal AT option, give up the 2-antenna switching
and reroute the ANT1/2 relay line to activate the RX antenna relay?
(needs to work with KPA100 installed)

I've loved using my K2 (finished in January) on 80/160, but switching
back and forth between the TX antenna (inverted L) and RX antenna
(beverage) is VERY cumbersome, (3 button presses) especially for use
in a contest situation.
