[Elecraft] K3 - modes and band/freq

[Dan Barker]

Just change the frequency first, and then set the desired mode. The radio
(whatever it's make or logic) will do what the programmer (operator) wants.

Kenwood protocol predates the per-band memories that modern radios have, I.e
the radio saves the mode and frequency you were last on, on each band.
If you send a mode, does the radio then have to wait X milliseconds before
acting on it to see if there is a frequency change coming next that also
will change the band ? 
How long should the radio wait?  
How long should X be? Kenwood have never defined it any place..  
Problem with this is that doing it this way slows down considerably the
speed at which the radio can respond to commands, not a good thing if the
application is doing more than simple logging or QSying.
