I wanted to thank everyone for their replies. This really helped me understand the technical and infrastructure issues of 1200 vs 9600.

Someone should try making adsb for ham radio
The only thing is the bandwidth
ADSB is just pulse position modulation.
Except its at 1MB /s
I think it's about 7 MHz
Could be ok on 1200 MHz ?
It is awesome to hear a 'click' like static that translates to a position report

Are there any components of ADS-B that might be transferable to a totally "new", UHF APRS system. We recognised years ago that ax25 has severe limitations and that better systems exist. Whilst we'll never change ax25 and 1k2 aprs it should be possible to devise an alternative network using new protocols to which users can migrate over a period of time.

Been thinking about this for a while
I thought 9k6 was less reliable.
Wouldnt you be better off going like FL-DIGI ?
