Doug,
On the BPF/Front End Board of the Omni 6 (81593) you can take the signal for
each band near connector 85.
I 've routed this to a small home made board with 13 diodes in a matrix to
produce bcd-code for each band.
The four wires with the bcd-code coming off this small board are routed to
the db-25 connector on the TX Audio Board (81597)
where they are connected to four unused pins.
I use the bcd-coded band signals for automatic bandfilter-, and antenna
switching.
Works fine here for years now, I can draw up a schematic an e-mail it to you
if you like.

Doug -
There are RS232 commands that return the frequency of VFO A and VFO B.
Usually these are interpreted by software which translates the hex
numbers into something readable. The same type of information is
available on the Icom compatible port. That way you can use the RS232
for computer logging and the Icom port to control your switch.
The commands are in the back of the manual.
You will need to program a chip to send the query command, to receive
the hex data, to translate the hex data from frequency to band, and to
throw the band switch. A daunting task.
Some computer logging/rig control programs will do most of the heavy
lifting if you can tolerate having the bandswitch work only when the
logging program is working.
Hope that helps.

I'm building a remote antenna switch (2006 Handbook, pg 19-37). I'd
like to pull band data from the RS-232 port for auto band
switching. The Omni 6 presents band data on pins 10 (160m), 15 (10/12m),
17
(15/17m), 21 (20m), 24 (40/30m) as +10v on each of these pins on a
DB-25. It was done this way originally for auto band switching with
I believe the Hercules amplifier.
The problem as you can see is the multiple bands on some of the pins,
which makes it really hard to automate the antenna selection process
when using separate antennas for each band
.
So here's the question, is there another way to get this info out of
either RS-232 or the separate serial port connector that I can
decode in the context of the antenna switch in the handbook.
I think there is a way as no logging software I've run across has a
problem decoding band, I'm just not enough of a tech to be able to
figure it out.
