I like Bob's idea of using different channels. That and the options
below are interesting to consider with our alt-frequencies.
Unfortunately we can't use the D700 (D710?) with split baud rates..
That would be interesting to transmit on the 9k6 channel and receive
on stock 144.39.

Subject: [aprssig] Now 5 APRS Channels!
To: TAPR APRS Mailing List <aprssig@tapr.org>
Here is an updated recommendation for APRS channels in your APRS radio. The
purpose of all these channels is to allow you to configure the A side of
your radio without ever turning down the radio volume on that side. This
makes sure you are always listening for voice alert calls, but can mute the
packets temporarily or change to any of these other functions without having
to touch any menus or function buttons.
Ch FREQCY OFFSETS CH NAMES TONES USAGE
-- ------ ------- -------- --------- ----------------------------------
1) 144.39 simplex APRS raw No tone for troubleshooting
2) 144.39 simplex APRSnorm CTCSS 100 with Voice Alert
3) 144.39 simplex APRSmute DCS xxx for quiet or selcall at APRS events
4) 144.39 + 600 APRSevnt CTCSS 100 for special event with lots of HT's
5) 144.99 - 600 APRSdigi no tone to be a WIDE1-1 offset digi
Notice, the change in channel 3. The reason is, that unless you program the
actual CHANNEL NAMES shown above, then looking at the radio, you cannot tell
the difference between channel 2 and channel 3 operation. Both show as
144.39 with CT. But if you make the "mute" channel use an unknown DCS code,
then that channel will appear as 144.39 DC which is distinguishable from
144.39 CT.
