I used my Tektronix RSA306 SA to tune into Heathrow Airport
airport to amuse my 4yo son who is a plane fanatic. All while watching on FlightRadar24. Huge success.
over Christmas. It could have been done by a SDR but I did not have one at hand
The RSA306 does 8kHz AM and 8-200 KHz FM demodulation - and the RSA306 is actually very capable with 40 MHz realtime analysis bandwidth. You can pick them up on eBay for $1300-$1600 now. That is a bargain for 9kHz - 6.2 GHz SA.
Software is a bit stupid in the UI - but I don't think I can mention a single manufacture of Measurement devices who are any good at writing software. Fluke, Keysight, Extech etc all make crap PC software IMHO - either looking like Windows 3.1 (Fluke) or like nothing (Keysight) or like designed in Asia outskirts (Extech)
