I've heard that you put the call out for a Sky Harbor feed.
My dad listens in on my flights when I'm at work and its a shame he can't hear when I'm taking off or landing at my home base (KPHX).
I tried to make it happen. I am 5 miles north of KPHX with a direct view of the airport, but as I said, my building has problems with radio waves (and I'm not entirely sure that the KPHX transmitters are on the airport or south mountain). I bought the AirBlade to try to make things work, but no-go.
So hopefully someone sees this and buys my gear.
