Short answer is: not a good idea. The K3 front panel PC board has top-surface gold-plated "landing pads" for each of the pushbutton switches. It might be possible to find appropriate vias (holes) at which to attach discrete wires to activate the switches externally. But this could introduce noise into the A-to- D switch read channels, and also cause radiated noise (RFI) to increase into the receiver.
A better approach would be to use an external pad of some kind to send commands via RS232 to the K3. Better yet: An Elecraft accessory keypad that plugs into the front- panel jack under the VFO B and RIT controls. That's certainly something we're considering. 73, Wayne N6KR ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
