Update: New and improved airplane stuff

A few new features have been pushed in the last two days. Most significant is rtl_adsb, a fast and simple ADS-B decoder. It is not the most sensitive decoder (Prog's and rtl-1090 pick up a few more planes) but it works fairly well. Of course it lacks the interactive maps of other software, however the output can be piped into fancier programs or across the network with netcat. To use it, just run "rtl_adsb". It does not need any options and can pick up plenty of signals with only the stock antenna. Here is a snippet if you plan to use rtl_adsb over the network: while true; do rtl_adsb -R | nc -lp 8080; done Where -R enables raw mode, 8080 is the port of choice, and the while loop restarts netcat after network disconnections. Rtl_fm also got a few tweaks to make it work better with AM voice airband. Rtl_fm could always do scanning but it needed every frequency listed out explicitly. Kind of awkward with hundreds of airband channels. So now you can use ranges: rtl_fm -M -f 118M:137M:25k -s 12k -l 280 | .... That will scan every voice channel. Adjust squelch level for local conditions. Also of note are two little convenience features in rtl_fm. If the output filename is omitted, stdout is assumed. And the use of k/M/G in addition to e3/e6/e9. -Kyle http://kmkeen.com
