[ham-ninux] mi sono fatto una ICOM ID-31E

Mon Apr 28 15:54:49 UTC 2014

DMR is the two-timeslot TDMA standard using a whole 12.5kHz channel 50%
(e.g.MotoTRBO) and Tier 1 is for licence free digital PMR446.
dPMR/NXDN is the 100% duty cycle FDMA standard (e.g. Icom IDAS) where dPMR
is 6.25 and NXDN is either 12.5 or 6.25

DMR: http://en.wikipedia.org/wiki/Digital_mobile_radio
dPMR: http://en.wikipedia.org/wiki/DPMR
NXDN: http://en.wikipedia.org/wiki/NXDN

Yaesu is “12.5 kHz C4FM/FDMA” then that suggests it’s NXDN.

It isn’t that simple anymore. While technically correct, Wikipedia is not
up-to-date. There are now many DMR products which do not support 2 time
slots, but aren’t compatible with dPMR either (other vocoder).

Best known examples are the Kirisun hand helds and the Hora mobiles.
