Aircraft enhanced 2m SSB
There’s a bunch of early morning 2m SSB enthusiasts on the eastern Australian seaboard who make long distance contacts on a daily basis by reflecting their signals off aircraft. Regular contact is made between Brisbane and Sydney (and points in between) a distance in the order of 600 km.
At the midway point of the morning session, those in Sydney (plus/minus a few 100 km) turn their beams to the south-west and do the same in the direction of Melbourne. I don’t know how successful that component of the process is; Melbourne is 1000 km from me as the crow flies.
I used to participate a few years ago, but don’t have time these days.
They can be found on 144.200 Mhz between 7 and 9 am (give or take). At other times of the day, the 2m SSB calling channel is 144.100 Mhz.
