Midland MXT275 15W MicroMobile GMRS Two-Way Radio

D0 No Radio — No radio at all. It cannot phone home.

The unplug test

There is nothing to unplug. The MXT275 is a vehicle-mounted GMRS two-way radio: turn the knob, pick a channel, press the microphone's push-to-talk button. It has a wired control microphone (RJ45 connector, not wireless), no Wi-Fi, no Bluetooth, no app, and no account of any kind. Every function documented in Midland's own user guide — channel scan, NOAA weather alerts, repeater channels, privacy codes — runs entirely inside the radio. Nothing about it can be revoked, updated against your will, or tied to a vendor server, because it was never connected to one.

Why this tier: Midland's own full user guide documents every control on the unit (channel/volume knob, wired RJ45 microphone, menu button, PTT) and every function (GMRS channels, NOAA weather, repeater channels, privacy codes, squelch) with no mention anywhere of Wi-Fi, Bluetooth, an app, or an account. The only FCC grant found for this model (MMAMXT275, 'MOBILE GMRS TRANSCEIVER') covers only the licensed GMRS/repeater frequencies (462.55-462.725 MHz and 467.55-467.725 MHz) used for the radio's actual transmissions, not a Wi-Fi/Bluetooth band. Per the FCC heuristic, a licensed-service transceiver grant is expected for a radio and is not itself evidence of a cloud connection; there is no cloud connection here at all.
