[Elecraft] K3 band data query

[Don Wilhelm]

Dennis,

Frequency data is available from the RS-232 data, but needs decoding 
which implies that a smart device is needed (computer).  See the K3 
Programmer's Reference Manual for the commands and responses.

I currently do this manually, but am installing vacuum relays for switching remotely. Is there a way the K3, through the data port or whatever, can send a signal when migrating between traditional (or operator defined) phone and CW portions of the band?
