For anyone with a k3 who needs to activate something based on the band in use, I recommend you take a look at using the DIGOUT1 connection on pin 11 of the accessory output.
It can be programmed in the menu to turn on or off based on the band and antenna in use. I just built a coax switch that switches between my Steppir and my auto tuner. On 20 meters up it turns on the coax switch and connects my Alpha to the Steppir. On 30 meters and below it turns off and lets the switch default to the auto tuner which handles all my wire antennas. I use a transistor switch keyed by pin 11 to a low 220 ohms to key the vacuum relay which switches the antennas. Works great. Might also be useful to someone using remote operation. Thanks to Wayne at Elecraft for his help and advice.
