Neat idea, need to investigate how targeted the disruption is. You can do a lot with very little power and noise by doing targeted disruption. EG target the sync window.

The 30m range to me indicates they might just be trying to blast noise on all 2.4 given the called out applications.

I could see this being useful to test the resiliency of RC control links. Some modern links operate below the noise floor, but can dynamically scale up power to 2w. They might be able to punch through just overpowering the jammer.

Could be useful to simulate a very high noise floor environment or flying around something that has a lot of spurious emissions.

Recently was flying a drone around an oil rig in Ohio. Now using a loRa based RC control link. This is the first time I didn't have any issues with dropped connection compared to previous control link systems.

I would love to test it out in the lab first to have higher confidence in the field.

This would be quite useful for taking out people who use Bluetooth speakers on hiking trails :)

Projects like this often refer to them being "For educational purposes." I presume the "education" is the user learning how the legal system works, the laws that get applied when they are caught and the typical fines imposed.

Sure that could be part of it, learning the laws is certainly part of getting your ham ticket. But let's step back from a less snoody POV, and view it from another angle. In your own home,…
