ADSB# has the ability to stream data to sdrsharp.com, but I don't know what they do with it.

ADS-B won't be awesome in the US for another 5 years, though. My office is at one of the busiest regional airports in the country. Very rarely do I see any aircraft that provide more identifier and altitude using my RTL-SDR and homemade antenna with ADSB#.

Very true if 5 years even makes it popular. Most regional carriers and even legacy carriers do not have ADS-B out in them. The adoption rate in general aviation is dismal. I believe under 5% is what AOPA is saying, my personal experience is 1 guy out of 30 owners I know has installed it. The benefits just aren't there yet.

Your antenna is probably bad. I live in the middle of nowhere USA and get planes all the time. (Using rtl_adsb.)

The ones I do see are typically freight carriers (FedEx, etc), or international airlines (Virgin). AFAIK, most of the flights into and out of this airport aren't those types. So, of the air traffic I do see, the majority don't identify with more than identifier and altitude. Lat lon is few and far between.

Regardless, his statement is true that ADS-B is not sufficient for full coverage in the US right now. I've seen estimates as low as 25% for the proportion of US carrier aircraft currently ADS-B. FlightAware in particular uses far more than just ADS-B.

Can you share how many and how far away? Are you near an ADS-B ground station (which will rebroadcast all traffic if a single ADS-B squitter/output is near) or only receiving active output from airplanes?
