Aircraft transponders 1090 MHz
« on: June 07, 2017, 2117 UTC »
Some time ago I wrote Cocoa 1090, which decodes aircraft transponders using an RTL dongle. I've been playing around with the app today, and now have it decoding from a netSDR, which is connected to the 10.7 MHz IF output of an R-7000 tuned to 1090 MHz. It's a bit of a kludge, but seems to be working.
