[Elecraft] Help: K3 - 2 Mic (VFOA and VFOB) 2 Computers N1MM

[David Gilbert]

I haven't investigated this completely, but I think I might have a 
suggestion that would accomplish the same thing using a single desktop 
computer (or a single laptop with an external monitor port):

a.  Connect two USB keyboards to your computer.  I've tried it and N1MM 
will respond equally to either one.

b.  Connect two monitors to your computer (requires a dual monitor video 
card).  Position the N1MM call entry and bandmap windows for VFO A in 
monitor 1 and the N1MM windows for VFO B in monitor 2.

c.  Operator B uses the pause/break key to switch N1MM windows, which 
also puts the K3 into SPLIT mode for transmit on VFO .   Operator B can 
then change frequency on VFO B using UP/DOWN keys or Up/Down Arrow keys 
(or, of course, by spinning the VFO B knob on the K3), and transmit from 
VFO B using N1MM macro keys.  Either operator can hit the pause/break 
key on their own keyboard to change the active window back to VFO A and 
take the K3 out of SPLIT.

d.  You'd have several choices for audio depending on cabling and how 
L-MIX-R has been set in the K3 config menu.  Options (b) and (c) allow 
better teamwork.

       a.  Operator A hears only VFO A in both ears and operator B hears 
only VFO B in both ears.
       b.  Operator A and Operator B both hear VFO A in their left ear 
and VFO B in their right ear with equal volume
       c.  Using an inexpensive external audio mixer (less than 50 USD), 
Operator A hears VFO A in both ears at normal volume and VFO B in right 
ear at reduced volume, while Operator B hears VFO B in both ears at 
normal volume and VFO A in left ear at reduced volume.

I don't have the DVR for my K3 so I'm not sure how to integrate it into 
this suggestion, but I'd be surprised if it wasn't possible.
