[aprssig] Fw: ADS-B to APRS Server

Andrew,

Just back home.

That rx is a bit pricey and I don't have any wealthy relatives, healthy 
or about to croak!

Do you know anything about the data transmission - data rate, modulation 
type etc? I guess what I'm getting at here is, is the rx technology 
beyond homebrew? A reasonably priced rx might be the road to some sort 
of network for increased coverage.

Somebody else mentioned tracking a plane going into Brisbane and losing 
it at 150ft. I observed the same thing. Is that the height of Brisbane 
airport, or do you lose the radio path when they get to that altitude?
