How to use DragonOS LTS, gr-iridium, Iridium toolkit, antenna, and the RTL-SDR to extract Iridium frames from the air.

I also explain how to add the osmo-ir77 codec in order to decode voice. I'll make sure to add the codec in the next build of DragonOS LTS, for now it's a quick procedure to add. Pay special attention to exporting the path as shown in the video.

This module provides blocks to build an Iridium burst detector and demodulator.
