1st Dual Band DMR HT.

[EricCottrell]

Hello,

The Baofeng DM-5R working with each other, and not other DMR radios seem to point to Baofeng misreading the standard. This can be easy to do with some standards. The software update that fixes the vocoder problem seems to point to this and to the lack of interoperability testing with other DMR radios.

The Baofeng marketing maybe directed to companies that only buy DM-5R for their communications needs, so working with other vendor's DMR radios is not considered very important.

"The DM-5R can't be upgraded to Tier 2, as the hardware (HR-C3000, RDA1846) does not support it.

Well, I got a DM-5r PLUS today as well and was playing around with it. When I connected it to the programming software, I got the name of the device displayed as "HR-C5000". As the programming software is a pain anyway, I would like to know, if that system name has already been this "HR-C5000" on the first models or not? If it really would be a HR-C5000, there would be hope for a real TIER-II operation ....
I tried to make some simplex communication possible between the BAOFENG and my RETEVIS RT3, both on TS1 and TS2, but the BAOFENG stayed mute. On the RT3 I always could hear the voice from the DM-5R plus ...

Also, using the DM-5R on a hotspot with a DV4MINI the same behavior was shown: My transmissions with the DM-5R could be heard, but I did not hear anything ... Should I also update the firmware with the "TIER-II" update of radiodiddy (what is just a codec upgrade, I know) or is there something else wrong ?

In the menu of the DM-5R plus the CP. ver. is shown as 102016, and within the CP programmer, on the page DMR Info, the firmware is shown as 1101 of 2016-09-21 ...

tnx es 73 de df5zx

Mine shows the same name, version number, and firmware # and date.

The problem is that there is no AMBE+2™ Vocoder in this radio!

Hmm, after some experimentation and filling up the lists with more entries, my DM-5R+ started to work with my DV4MINI hotspot, both connected to DMR-PLUS and BRANDMEISTER. I most probably had forgotten to set some data to the right values. It works out of the box without the "TIER-2" upgrade from Radioddidy...

Regarding the Vocoder chips, I am really wondering. When I was searching for some info about the hr-c3000 system, what was meantioned often before, I got to some info sheet in chinese, what also mentioned the hr-c5000. There it was written, that it is able to do tier-2 ...So, you think it has only a soft-codec for AMBE2+ ?

As soon as I am home again I will check this DM-5R+ for the known problem that it does send always on TS1+TS2.

At least for hotspot with dv4mini and simplex operation, I can confirm that it works.

I have a couple questions about this dm5r first can you scan analog and digital at the same time, also i wont be using it to transmit just recieve local dmr traffic, will it recieve standard simplex dmr if i have ts and cc programmed?

Just run away from this POS quickly and avoid getting sucked into the Big Black Hole. :wink:

Absolutely. Unless you want to use them as an Echolink simplex node. Sooner or later Radiooddity will clearance them out to cover their losses. I'll grab some for that purpose. Maybe they offer an extreme discount now, to buy customer returns.

Radiooddity says "they can communicate with any Motorola radio" Big whoop. All my radios can too...in analog mode.

Means nothing.

Finally, after two requests for a refund, I opened a PayPal dispute. Radioddity replied for me to email support@radioddity.com and request an RMA. I did and just this morning finally received an RMA so I can return this POS to them. I note that the return address is in Lenexa, Kansas so there's no problem with having to send it back to China!

I also note that their sales page for the DM-5R now clearly states "Tier II, Slot 1 only..."

They promise a refund within two days of receiving a tracking number of the package being shipped back.

There's a word for that. If it's tier 2, it does 2 time slots. If it only does 1 time slot, it's tier 1. Can't have your cake, & eat it too. Too bad there's not a Gov't agency that can go after these people for false advertising, or importing JUNK.

It used to be the FTC (Federal Trade Commission), but I'm not certain that they really care that much about false advertising these days, especially when the (monetary) stakes are low.
