APRS for trains. Boats and ships are next. UAIS.
http://www.navcen.uscg.gov/marcomms/ais.htm
By the way I read the regulations/trends EVERY boat (including private
craft) over 26 feet or with more than 600 HP will require a AIS transponder
by 2010 if operating in coastal waters or waterways that can easily access
coastal waters.
Although the theoretical limit is 2250 slots per minute, has anyone looked
at how many boats are in, say, Mission Bay or Chula Vista at any one
time? Imagine how crowded that display screen is gonna be... (even boats
at anchor are required to transpond).
Furthermore is this really gonna stop terrorists and drug/people smugglers?
And couldn't someone so inclined really create havoc by jamming the 162 Mhz
frequencies? I recall being told that certain middle eastern groups have
already engaged in VOR spoofing in North America. And wasn't there an
incident in Seattle where every RF-based entry system for cars quit working
for several hours one day?

If you believe that PropNET is APRS reconfigured for propagation study
(which it is), then the following are in use for 1200 baud AX.25, too:
147.585 FM
50.620 FM
28.128 USB

Not the mention the non-intentional GPS jamming caused by a oscillating
TV antenna preamp on a boat that took out GPS all around the Monterey
Bay area. [ Story I posted here about 6 months ago. ]

Gents,
I want to decode POCSAG THD7A audio out is not working.
Should I proceed to use the DISC out on the D700 ?
Has anyone had any success with a sound card.

I had no luck with DSC decoding with either AGWPE or a PK-12.
Is there a way to receive it besides another marine VHF?
Thanks,

One of the DOS based ham radio programs claims to decode DSC via data
slicer. RadioRaft? I think there were some restrictions as to what it
decodes.
Can't verify that it works, with living in South Dakota and all... :)
