Hi,

Anyone here have the MotoTRBO ETSI specs handy?

Particularly, ETSI TS 102 361-2? For some reason, the link is broken at the ETSI website.

Thanks in advance!

Did you try Google for ETSI?
Also, RR has a site, which is:

Tom,

Thank you for the quick response. Yep, I been there already.
Actually, I had been Googling the ETSI specs for a few hours already.
I had already been to China and back -- I saw the pdf's there, but I could not read the Chinese writing.. haha

Any help will be GREAT!

Thank you all in advance for trying! :)

I've been asked to weigh in on this, as I have access to the MotoTRBO specs at work.

The way the ETSI TS 102 361-* relate to MotoTRBO is that MotoTRBO is compliant to the ETSI spec.

However, the ETSI spec for DMR does not fully specify things - you can have 2 radios that completely and correctly comply with the ESTI spec and they may still not be able to talk to each other, because the ETSI spec leaves out things like "What vocoder to use?" "What bits map to what vocoder inputs?" and so on.

MotoTRBO represents ONE possible implementation of ETSI TS 102 361, with the unspecified areas defined in a certain way by Motorola.

However, with just the ETSI specs you aren't going to be able to make a MotoTRBO compatible radio - you'll have to have some way to work out the unspecified areas, either by reverse engineering or by getting the specs from Motorola.
