[OZAPRS] APRS HELP

[G T & C A Beagley]

I guess packet must be legal on Aircraft band AM as we have a packet 
data feed to/from the SITA network in the equipment room at the Control 
Tower here in Rotorua. Frequency is 131.55Mhz AM and I think it is a 
world wide Airline Packet data frequency. Aircraft transmit and receive 
on that frequency and the nearest ground receiver feed to/from the SITA 
network. Haven't got round to decoding anything yet as I'm not sure if 
it is 9600 baud or 4800 baud. Sure is short bursts though. The bursts 
get into our computer speakers in the tower if they are switched on, 
probably because they are only a few metres away from the antenna on the 
roof. We also had one installed in the equipment room in the tower at 
Port Vila, Vanuatu when I was there. They seem to go all day and night 
but no idea which aircraft were using them.
