I got a hotair soldering station ima try my best :D But i think most of the cheap ones arent bga but look like this one:

I took a look into those “toy” tablets in the 40 bucks price range, most of them seam to have a clearly visible Wireless chipset for wifi/bt, guess ima try to desolder and hope it still boots after.

I am looking for a solution that can run AndFLmsg, sure i could just run Fldigi on a RPi but the solution has to be usable for people who need a simple interface. Using a SBC to emulate Android apps with Waydroid would also be a option but i try to keep the emulation layers to a minimum for power consumption reasons.

U can put apps and data on it via USB otg, that wont be a problem.

Cutting the antennas is far from removing the problem, even without antennas those chips still make a lot of noise in the 2.4ghz band. Id woud have the desolder the whole wireless chipset, i mean i have the soldering equipment for that, but i kinda doubt that a normal android will even boot after the Wireless chipset is gone :/

Audio Modem

Android on PC sounds good, the power consumption would be high tho, and i would prefer a smaller form factor. But a old netbook mainboard + bliss OS could be small enough.

The Librem5 would be perfect, if it wasnt for the price

theatrics, they are already in

Silver should have good reflection over most of the spectrum, guess its the coatings making things strange then :/

Do you have the silver or the golden ones?
