To help collect info on the use of 144.99 for an alternate
APRS input channel, I have prepared a file that lists
all reported uses of 144.99 across the country.


Please consider checking on the frequency in your area
and reporting.  QSY your packet system there overnight
for several days and see if you collect any existing packet 

 You might also consider transmitting a "Is this frequency in 
use" packet say once every 2 minutes for a day or so (less 
than 1% of channel capacity).  Include your Email address
in case anyone see's you...

In the future, so you can find my links to this 144.99 stuff, 
I have added it to the usual APRS errata web page:
