In a hypothetical revolution who would secure the resistances comms?

Carrying a GPS tracker wouldn't be the smartest thing to do, wouldn't we need someone like Europe or Canada who control their own satellites to assist?
Would this spark the beginning of a space war?
Use radios: Gmrs or Ham
Do not transmit from your base, travel somewhere further away, then broadcast. Change location of broadcast every time.
Use encryption.
One method is using my Rattlegram + SSE method (both open source)
Rattlegram is a mobile app that converts text into audio
You play this audio over the radio, and the other side can use this to decode and get back the text.
All you have to do is encrypt the text using any open source program. I like to use SSE (Secure Space Encryptor / aka: Paranoia Text Encryption on iOS). You could also use PGP, but it would take longer to transmit the message since asymmetric encryption results in longer ciphertext.
Copy-paste the ciphertext into Rattlegram and voila! (Just reverse the process on the other side to get the plain text)
Obviously you shouldn't use any iOS or Googled Android. Use Graphene OS or something like that. Physically disable the antennas on the phones, you need them airgapped.
Alternatively, you can use One Time Pads, although it would be slightly harder to generate, distribute, and store OTPs, but if you use OTP, you wouldn't need to rely on digital encryption, and its more secure, but it'd be much slower to manually encrypt your text.
For resistance radio stations: Shortwave - although there aren't really any interesting stations right now, but if a civil war starts, I could see someone in Canada or Mexico start broadcasting to give the US revolutionaries info. Shorwaves can travel long distances.
I'm going to point out, for the technologically illiterate, that GPS satellites do not in any way track people.
GPS satellites go "beep" and by listening to the timing of those "beeps" from different satellites, a GPS receiver on earth can determine it's own location via triangulation. It's a bit more complicated than that, but that's the basic idea.
The only way you can be "tracked via gps" is if your GPS tracking device is also transmitting information using some other method (cell phone, radio signals, non-gps satellite connection, etc.)
This is correct, but that said if you're doing anything Donnie don't like, especially something you'll likely be investigated for, your position can be actively tracked via cell towers, and software backdoors will happily record and transmit your GPS position over the internet, even disabling all this stuff you can never really know for sure, so keep that phone off.
GPS devices only receive GPS signals; they do not broadcast any data. So carrying a basic handheld GPS device won't give away your position to anyone else. However, a smarter device like a phone or InReach emergency locating device can relay your location to others.
For communications, lots of people would suddenly get really interested in VPNs and encryption (for using the existing Internet), private wireless mesh networks (for city- and region-level communication), and even amateur radio. Owners of mesh nodes or radios would need to limit their broadcasting time and/or do a lot of moving around to avoid being located.
The same supplies of the current communications. Eriksson, Nokia, Samsung.
Look no further then central American drug cartels who built their own mobile network to avoid lawful interception.
NVIS is hard to locate without flyovers. It bounces the signal of the ionosphere kind of like a water hose shooting water straight up . Transmit and reposition. Range is up to 800km's .
Alt flood of meshtastic nodes, without GPS data provide encrypted rebroadcast capability.
