I know there are a few on the list that like watching balloon flights
so I thought I would point out Jerry Gables auto alerts system.

I have messaged Lynn to see if this can be linked to the ANSRVR BALLON group.

The auto detect website is http://www.s3research.com/flightdata/

And the group for email alerts http://groups.yahoo.com/group/ARHABLaunchNotifier

Seems to work very well

Now 5 APRS Channels!

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.

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.

-- ------ ------- -------- --------- ----------------------------------
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.
