[chirp_devel] Support for older Kenwood TM-2x1a (was Re: Kenwood TM-281a works, too)
Anyone know how far back serial programming capability goes in the Kenwood TM-2x1a line?
I'm winding up with an old TM-231a as a backup rig. It looks like there are serial pins on the mic connector but I don't see much info about it. I don't have the radio yet.
From some probing/fuzzing N9XLC was doing it looks like at least the TM-241a has a bit of an async. serial interface as well as possibly a synchronous serial mode to work with the remote controls kenwood made at the time. The TM-231a manuals mentions the availability of the remotes too.

Cool, thanks. The way kenwoods are designed, I'm not at all surprised that it works. I've added it to the list!

Oh, the good 'ol days when solid monobanders were cool and not just for newbies :)

Looks like there's some sort of functionality expected, based on the accessories available:

I have (access to) a TM-251 and it's so (damn) simple I have a hard time imagining it being PC-programmable, and it's two generations newer. We don't even have things stored in it -- we just use the VFO.
I'm not exactly sure what the contemporary commercial equivalent was, but I know that the TK-705 is programmable by computer via some sane serial interface and it looks darn similar to the TM-231,241,251-era devices.
