the trikes and drifters and Jabiru's and Savannah's can power a small radio, and can also power the ADSB out unit.
Fair enough. You'll have to convince Frank though!
A radio and a transponder would suffice though IMO.
I have had a fair amount of experience at Broome with it's Unicom oops CAGRO. I think they work well provided the operator doesn't go overboard. Good stepping stone from a CTAF R to a tower. Oh yes, now I remember, I also had a lot of experience with AFIZs, both local and remote, until they got dicked by someone... They also worked well.
