[Elecraft] K2 digital mode questions

[Hank Blackwood]

Joe…
Thanks for info!  The complete mic switch is a little more involved than I can maybe do, but just a simple switch using an old DB9 switch box with the MH4 in one position and the Navigator in the other should be ok. 

Thanks again - I’m loving this little rig!!
