Actually, after Katrina, the ARRL made it an initiative to come
up with a mechanism for determining and distributing the
OPERATING frequency of all stations on the air, so that they
could easily be found when needed.  It is called WOTA for "Who
is On the Air".  Since we have always encouraged the addition of
Operating FREQUENCY as a standard field, we tried to make APRS a
big part of that initiative.  But I got little support.  But we
have now formalized a standard for including FREQUENCY in APRS
packets to improve this situation down the road...

What I want to see are PIC processors connected up to Home
stations that will MONITOR the operating frequency of the main
RIG in the hamshack and automatically insert that frequency in
that station's APRS *local* beacon.
I do not want to see these beacons all over the state, but
simply locally, so that if the need arises, that person can be
contacted.

In fact, I think it would make a nice set of Add-on's to many
client software so that that software could monitor the stations
other radios and include their operating frequencies in that
stations beacon.

IN fact, a TinyTracker or OT tracker or any PIC device could be
made for the major CAT interfaces for Kenwood, Icom and Yeasu.
Plug this device into the shack radios and plug it into an
unused HT on the APRS channel, and there you go...
