That is inaccurate. You will NOT be able to jam a satellite outside local areas, the amount of power to do is monstrous and likely to cause cancer for anyone around.

In a real scenario these things work. Please don't fall into "what if's" which are exotic and confused as things bigger than what they are.

Well, from the comments, here, this sounds like a passionate topic, for folks.

I've always been interested in helping folks that help folks.

I started looking at Meshtastic, some years ago, but found the ecosystem to be a bit overly-complex, as is often the case, with "Swiss Army Knife" approaches.

> You will NOT be able to jam a satellite outside local areas

It is true that you will not be able to jam the _downlink_ frequency outside local areas.

But due to the FM capture effect, anyone else in the same hemisphere with a basic 100w transmitter (and appropriate antenna) on the _uplink_ frequency will be able to deny the satellite service to all the 5W Baofeng radios that preppers are stockpiling.
