[FADCA] 144.99 MHz

Chuck...

I doubt the Wormhole group is on that frequency.  However, 144.99 MHz 
is being used in many parts of the country as an alternate input 
frequency for APRS.  Some folks have figured out you can run full 
duplex is you uplink on 144.99 while receiving return packets on 
144.39.  It is something that is being discussed here in West Central 
Florida and other areas where there is a concentration of APRS Weather 
Stations.
