[aprssig] The East will Rise again! (at 9600?) Freq LOG?

[Robert Bruninga]

Those within 100 miles of the Appalachians, lets do a FREQsurvey.  That is,
every night put your radio on a different packet freq and run 24 hours and
see what you capture.  This time, lets really tabulate the results and we
can even make an APRS object map for every packet  freq from Maine to
Georgia.

Then we can pick the best freq for our 9600 baud backbone.

These are the frequencies to monitor:
144.91, 93, 95, 97, 99
145.01, 03, 05, 07, 09
145.51, 53, 55, 57, 59
145.61, 63, 65, 67, 69
145.71, 73, 75, 77  (79 is guard band for ISS)

When we find things, we will create APRS objects for them of the form:
PKTFFSSxx
> where PKT* makes them searchable on APRS maps
> where FF is the two digit frequency above,
> where SS is the state
> where xx is a UNIQUE identifier when more than one

That is the 9 digit object name, then you add your best guess of location,
and PHG data.  If that is unknown, then put it in the form of a DFS signal
strength report and that will plot a hearing circle around your location.

We could each just beacon these, ourselves or if you dont know how, send
them to one of us that can keep them in the system?

Every few years, I ask this kind of info, but we dont egt anywhere or I
loose the feedback.  SO this time, lets make a concerted effort.
