The R820T dongles usually have a low frequency limit about 54~60 Mhz, for receiving signals below that limit you need a up converter like this:

I have a program on my computer called PC-HFDL that captures the packets from my HF rig and displays them via google earth. There are programs such as Plane Plotter also displays this info. Instead of using 1090, there are various frequencies used between 5Mhz up to 28Mhz or thereabouts.

I'll see if I can make a short video of it in action for you.

Two questions:
1. How do the FAA track planes mid ocean (satellite, buoys, other)?
2. Why does the FAA data plot 'avoid' the t- plots from Ireland (do the FAA not capture the data, do they not share the data or does FR24 avoid plotting the FAA data)?

FAA's ADS - B Installation Guidance
http://www.aea.net/Training/courses/...20Guidance.pdf
I've been trying to find out what antenna on the aircraft is used for the ADS-B Out. From what this says, the same S Mode transponder antenna can be used. It also recommends the use of 2 antenna, one on top and one on the bottom of the aircraft. The top mounted antenna is not mandatory, however in my opinion it should be, if they have plans to track aircraft by ADS-B satellites.Tags: None
