As an amateur radio operator, I occasionally use my 2 meter and 70cm hand held radios as the transceiver portion of a packet setup. I wire the audio output from my radio to a dedicated TNC (terminal node controller) which is then interfaced to the PC, but others feed the radio audio output into the audio input on a PC audio card and use software on the PC to handle the modem function and eliminate the TNC.
There are a couple of threads on the internet describing how to use a surplus satellite receiver as the starting point for an ADS-B receiver, tapping into the IF portion of the circuit to capture a usable signal, but it looks like way too much work and technical knowledge required for me if I already have a radio capable of receiving these frequencies.
I was wondering - I have an Icom scanner capable of receiving the 978Mhz and the 1080Mhz frequencies. If this scanner could receive the correct modulation, it seems like one might be able to construct a similar setup to packet described above. I know that software would need to be written, but the data sequence is a public specifation. If you could use a relatively low cost scanner and your existing PC with a graphical depiction on your PC screen to monitor ADS-B traffic in your area, it might be fun and useful.
Has anyone tried to constuct such a critter? Is it even feasible?
