  • Define “communicate”.

    With who?

    Over what distance?

    Also for what kind of scenario?

    There’s probably some more things to define first, which will help guide a solution.

    In a nutshell, over short/local distances (1/4 mile to perhaps 5 miles under ideal conditions, which never happen), GMRS can be used. It’s easy to learn. But it’s very range limited in general.

    You could setup your own repeater on something high, and get miles of range then (I regularly pickup folks 10+ miles away because there’s a repeater half way between us on a tall building).

    Long distance, HAM/HF. But that’s very complex, you really have to learn quite a bit to make that happen, and whoever’s on the other end would need similar skilset.

    CB can do significant distance too.

    With any radio, the higher the antenna, the farther the reach - that’s the primary driver.

    Radio is a helluva rabbit hole, but I’d recommend starting with GMRS - radios are fairly inexpensive, you can get started for about $100 if you find a deal on a radio 2 pack (and not the cheap blister pack crap, something like TidRadio or better).

    Cell phones are just radios that link to a repeater nearby - the cell tower. That tower then links to the phone network, typically via cable.




  • Lol, I get it, I often start doing the math and realize “someone has already done this”.

    Cool, thanks for the link. I already knew the little 12v batteries suck (though they work fine for the intended purpose, like impact driver or work light). I kill them with any other tool.

    Yea, I was just thinking is the runtime reasonable enough that having spare batteries is a sufficient approach. Like you said, long runtime isn’t required, 15 minutes total runtime is probably more than enough (though that would be hell on battery life cycle).

    Since I already have a slew of Milwaukee batteries, I’m trying to avoid things with 18650, except where form factor matters (like my flashlights). A Single Battery to Rule Them All (or at least most things).



  • Without being able to root, it’s a challenge.

    I’ve had Verizon Samsungs for years and dealt with this.

    Start with the Universal Debloat Utility. . Note what it says about disabling some things isn’t advisable. The recommended list is safe - I’ve used it extensively on Samsung.

    After that, yea, something like RethinkDNS will help. I’d use it, but chose to run No Root Firewall to control network access (there are others, this is the one I’m familiar with). It acts as a VPN to provide the firewall functionality. You could then use another DNS provider that blocks ads and such (since ReThink also needs to run as a VPN).

    I’ve disabled most factory apps, and several Google apps. You can disable Play Store and it’ll work OK. If you disable Play Services you’ll get error pop-ups frequently.

    This is about the best you can do without being able to unlock the bootloader.

    I’d start with a reset. Then setup the phone without a Google account, then run the debloater.

    After that, do what you like.
