Constant PROG on screen Kenwood TK-3180 K

[dryfb]

That's when you put it into firmware programming mode via the S + Power on sequence. That would show on the screen as:
PROG 115200

With it only showing PROG, that seems to suggest the firmware is borked.

An unprogrammed/new radio would show as "UNPROGRAMMED" on the screen. Once programmed for the fist time, that's gone unless some reprogrammed it and set up a channel text name as "UNPROGRAMMED".

if you disconnect or turn off the radio while writing it'll say UNPROGRAMMED afterwards and be factory reset. Also think that if you don't have any channels it'll say that as well, at least on the first gen NX radios.

@buddrousa as far as battery drain, my TK-3180 sits on my desk for a week or two between uses without battery drain (Power Products BP5633LI). It has either 1.21 or 1.22 FW (possibly custom for some kind of LTR/scan issue). What kind of battery have you? There are some fake KNB-33 out there in the world that I think I remember won't hold a charge. Old NiMH could do that too. Could be a VHF-only prob, too.

My TK3180 stays charged for a very long time without use on Firmware 1.21
