Description
A complete three-piece mobile install pulled from fleet service. It powers on. It is NOT programmed, and I do not program radios. Read that before you buy.
Bench report
- Functional
- Powers on. Both the deck and the control head come up when power is applied, and the display lights. The control head was photographed powered up so you can see the screen for yourself. No transmit, receive, audio, or alignment testing was performed beyond that power-on check.
- Cosmetic
- Used fleet-vehicle condition, and honestly on the rougher side cosmetically. The deck housing carries visible scuffs and scratches, which you can see in the photos. Nothing is cracked or bent, all rear connectors and the antenna jack are present and undamaged, and the nameplate is fully legible. The control head and speaker are in better shape than the deck.
- Tested
- Deck powered on 2026-08-27. Comes up with power applied · Control head powered on a bench supply and photographed. The display lights and every character is legible. The screen reads "WARNING! Lost MRU", which is simply the head reporting that no radio deck is attached: it was powered on its own for that photo, not wired to the deck. That is the expected message for a control head running standalone, not a fault. · Power cable present, intact, and mated to the deck · Harris hand mic attached on an intact coiled cord · Deck nameplate photographed and fully legible. Model, serial, FCC ID, IC all readable · Rear I/O inspected: antenna jack, DB25, DB9 and power connector all present and undamaged · All three pieces photographed individually plus a full bundle shot
- Not tested
- NOT PROGRAMMED. No codeplug loaded, and no programming service is offered with this sale · Transmit power and deviation NOT measured · Receive sensitivity NOT tested · Audio quality through the mic or speaker NOT tested · Alignment NOT checked and NOT performed · P25 or trunked operation NOT verified on any system · Speaker NOT audio-tested, though its cable is terminated in a 2-pin connector rather than bare leads
