As a pilot with an amateur radio license (though an inexperienced ham) this sounds really interesting. Could you elaborate more on building the VOR receiver?

- mikewarot 2y agoThe transmitter has an electronically switched antenna that virtually moves in a circle at 3600 rpm, causing FM modulation phased with direction. The carrier is also AM modulated with a reference phase signal. I built a gnu radio flowgraph to receive both and display heading to the VOR.
- mikewarot 2y agoSorry I was working from memory yesterday... It's 1800 rpm / 30 Hz, not 60. https://en.wikipedia.org/wiki/VHF_omnidirectional_range https://en.wikipedia.org/wiki/VHF_omnidirectional_range
- pyinstallwoes 2y agoWoah coming from a dsp / synth background that’s wild to hear.
