Radioddity posts a response to some of the questions about the DM-5R and it's DMR capabilities:
Rumor 1: The BaoFeng DM-5R is not compatible with MOTOTRBO TIER 2.
FALSE. While the BaoFeng
DM-5R comes out of the box only supporting Tier 1, it can be easily
upgraded to support Tier 2 online. The upgrade will be available at
Radioddity.com as well as BaoFeng’s official website (under
construction). This upgrade costs less than $10.
Rumor 2: The BaoFeng DM-5R is a dPMR, not a DMR.
FALSE. The standards for a DMR are as follows:
TS 102 361-1: Air interface protocol
TS 102 361-2: Voice and generic services and facilities
TS 102 361-3: Data protocol
TS 102 361-4: Trunking protocol
The DM-5R meets each of the ETSI Standards listed above. A true DMR, not a dPMR.
Rumor 3: The BaoFeng DM-5R is not FCC or IC certified.
FALSE. The BaoFeng DM-5R has
met FCC and IC standards in its testing. The documents may not be
visible online, as it takes about 4 weeks for the documents to be
available.
They still don't give specifics on how to get Tier II - only mentioning the $10 upgrade.
