[WT-support] Elecraft K3/K3S slow bandmap

[gt-i at gmx.net]

Bob, Stefan,
I just checked, here is my result:
K3 (FW 5.6)
set AutoInfo to 1: K3 sends out IF-msgs while moving the VFO knob, even 
on 10Hz changes.
    admittedly, the time between the messages does not exactly 
correspond to how fast you turn the knob

set AutoInfo to 2: K3 sends out FA/FB messages, WT does not react to them

KX3: (FW 2.9)
same as K3

K2: (FW 2.04)
same as K3, except it only sends messages after the VFO knob stops with 
a delay of about 1-2 seconds.
