I don't know individual model numbers, but I notice that few commercial radios are supported in Chirp right now. DMR is becoming popular and may soon surpass D-STAR (for many reasons) as the preferred VHF/UHF digital voice mode, and the MotoTRBO system seems to be the favorite. Is there any particular reason why these commercial radios can't be supported?

Modern Motorolas' memory, at least according to my simple test, are encrypted and therefore cannot be reverse engineered. I only checked my HT1250, but I suspect this applies to the DMR radios too. Since discovering this, my conslusion has been to stop buying Motorola.

Just to echo what Tom has said, the reason for not touching Moto with a ten-foot pole is around possible legal repercussions.
Moto is known in certain radio programming communities to aggressively assert it's legal weight around RSS.

This is an interesting read:

I would recommend that more Moto patrons provide feedback to them that they desire more open radio programming choices.
Moto's attitude might soften to enough customer pressure - you never know ;)

OMG, I heard they were cranky, but this is just ridiculous--I thought I had read most of Repeater Builder's pages in years past, but missed that one completely. This is just insane...

As for encrypting the memory, that is very strange, but I doubt it's really that hard consider all the other things being broken nowadays. Hell, 25-30 years ago I was breaking copy protects and such. I don't buy that ANYTHING is impossible to reverse engineer: difficult, yes, but...

Still, if things are this bad, I'd be afraid of being sued, too. :(
