VORs and SDRs Part 1 & 2 Supplemental materials

Part 1

Part 2

I want to share some supplemental materials to go along with this video. In the attached zip file, I've included the raw samples (32k/sec sample rate, roughly centered carrier) and the GNU Radio Companion file for basic processing. I'd be very interested to see if others can squeeze out a little better performance.

Also, this is the path that I took. It may help understand the angles. I need to make clear that I'm not at all certain that the absolute angles are representative to compass points. I'm only looking at relative angles at this point. Eventually I'll calibrate the system using a known VOR calibration location (there is one at the Corvallis airport).

This is the path I took while collecting the VOR data. Ignore the drive time
