Software Defined Radio: See the Waves, Sniff the Air

Note: All I have is 2 weeks of experience with SDRs.

I want to share about this cool technology that all Set-Top Boxes technically have i.e. the ability to tune into certain frequencies.

The talk will include the following topics:

1. How to get yourself an SDR (Licensing Aspects)
2. What is an SDR?
3. Scanning FM Bands
4. Shortwave Radio Listening (global stations, weather stations, etc.. )
5. Police and Emergency Communications
6. Listening to Air Traffic Control (ATC) --> a legal grey area.
7. Live Tracking of Ships using AIS --> (https://x.com/arunmathaisk/status/1843734089045852467)
8. Tracking Satellites ( Downloading Earth Images)
9. GSM Traffic (Passive Interception) --> 2G is phased out in India

I would ideally like to show the live demos of all the above, but depending on antenna posting availability at the venue, the demo scope may vary :)
