Most definitely

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

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.
