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 operate a vertical antenna for 80 & 160M where the bandwidth is such that I
need to switch in reactance between the phone and CW portions of each band. 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?
Antenna matched points on 160 are at 1825 and 1855; 80M are 3520 and 3800.
I had considered sensing the K3 mode, but that’s not an acceptable solution.
The 160M CW contests can often extend into the traditional phone area and
FT8/WSPR often use USB mode in the CW portion.
