[aprssig] Now 5 APRS Channels!

[Bob Bruninga]

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.
