I'm seeing a lot of stuff from motorola pushing these MOTOTRBO radios.
How do they work? They're NOT p25 are they?

No good
I worked at a hockey arena a few weeks ago and all of the staff got new turbo's. I asked them how they are and they all hate them. They use to have old traditional radios and they want them back, but...to late...and all they do is work inside the arena.

Hi Mark,
They seem to use a 2 slot TDMA platform. And here I thought TDMA was on it's way out. Here read this:

MotoTrbo is two slot TDMA.
It is not trunked.
It is targeted at the business user.
It is not P25
It is a ETSI standard,
It does not appear to have a second source (yet).
Think of it like an improved 2 channel community repeater system running on one channel.
TDMA is not "on the way out".

We got to test them for a week when our dealer got their demo units in. Over all we were pretty impressed. They sounded good in both analog and digital modes.

Second source is ICOM. Check out the F3061 (VHF) / F4061 (UHF) portables. ICOM in the UK also has a PMR446 version over there.

ICOM's digital is NOT the same as Motorola's MOTOTRBO!n1das said:

OK, then what is specifically different between the two? Both use the same ETSI TS-102 361-1 standard.
Note that I'm NOT referring to Icom's P25 portables and mobiles.

From what I have seen the ICOM digital is 6.25 kHz FDMA not 12.5 kHz TDMA.

Is the Icom scheme for the F3061 / F4061 radios the same than as D-Star on the amateur rigs?

It may be similar, but I doubt it is the SAME.
