Join us for a quick 'how to' demo. Learn how to use an RTL-SDR device to pick up data from radio waves using open source software. Find weather reports, decode radio packet data, scan frequency ranges for local activity and much more! You'll be surprised at what's out there!
As always, join us in Matrix room #opensource:glasgow.social if you have any questions or want me to cover something specific.

To generate the heatmaps of what's happening in the radio spectrum in your area, use the
rtl_power (in the rtl-sdr debian package) with heatmap.py. For more information see http://kmkeen.com/rtl-power/
Run this for 24 hours (you can also just try an hour or so and repeat to test different aerials):
rtl_power -f 24M:1700M:1M -i 100 -g 50 -e 24h data.csv python heatmap.py data.csv
