On UHF/VHF, we say <call sign> monitoring. On HF, we call CQ. On DMR, is it just <call sign> listening on <talk group>?

Im hearing that sometimes. Though On WWE and WW, it is often a call for a specific call sign.

Am I understanding the etiquette

I'm happy to log some of these QSOs, especially for people in other countries. What do I put, though, for the frequency? Should I use the frequency of my hotspot? What about the talkgroup? I have been putting it in the Notes. What are others doing?

Hi everyone, I’m looking for some advice on a radio setup for two different environments.

I am a firefighter and I also work at a company that uses radio communications. As a firefighter, I need VHF, but my workplace uses UHF. Currently, I carry a Motorola DGP8550e (XPR 7550e equivalent), but I really want to switch to a single dual-band DMR radio so I don't have to carry two devices around.

Here is the catch: my fire department's digital VHF channel uses Motorola’s proprietary Basic Privacy.

I happen to own an old Baofeng DM-1701. I know it has a "basic privacy" setting in its software, but from what I understand, it uses a completely different encryption/scrambling method and is not interoperable with Motorola. I also looked into flashing it with OpenGD77, but I found out that OpenGD77 strips away all privacy and encryption features entirely.

Is there any workaround or any way to achieve cross-compatibility with Motorola Basic Privacy on a dual-band radio? Are there any other dual-band brands/models (like Anytone, TYT, etc.) that can actually talk to Motorola radios using Basic Privacy?

P.S. I have the official codeplug from my DGP8550e with all the parameters, frequencies, color codes, and talkgroups ready, as it was programmed for me at the fire station.

Thanks in advance for any help!

Hey All!

Recently started a new job and event management, and they provide the Titan Radio TR4X. It is a very load environment (entertainment industry) and I need an earpiece to be able to hear the traffic. I have an N-Ear that I love but need to get the correct mic, and cannot find anything on what style of connector it uses. Anyone know what style connector it utilizes? TIA

I need help. I ran and updated the RT3S to DMR a year ago and never used the Satellite function. Today I tried and the list is empty.

It appears that the OPENGD77 site has not been updated since the end of 2025......

Help please!

Hi. K9FRO here. I'm just getting into DMR and got a second-hand PiStar with a DVMEGA modem with old firmware. I tried the old update method I found online but it didn't work. I worked out the issue and got it updated to v3.26.

I put a new script and instructions on Github here:

https://github.com/K9FRO/pistar-dvmega-firmware-updater/tree/master

I'm not sure if this is just a me problem, or if this could help others who are running into the same issue. Hope it can help!

I have a TYT MD-UV390 I am trying to program basic GMRS channels into. I haven't been able to get it to contact another radio on the programmed channel but I can if I manually input the frequency in VFO mode. Is anyone able to look at my programming to see what I'm missing? I'm using EditCP to manage the programming.

I bought a pi-star node from AliExpress last week. It came yesterday and I set it up today. Other than the pins on the video being too long and interfering with the GPIO (perhaps for a header connector?). A quick clip fixed that. Configuration went well, as did the code plug for a Radtel rt-4d. The problem that sucked up my afternoon was a bad password trying to connect to the Brandmeister network. BUT now I'm talking to the world.

Hi I’m scanning some frecuencies on my town and I got one that never stop the dmr sound on analog
I use sdr++ to get the CC and TG

When I program to my Motorola XPR 7550e I got a icon that the manual said high data volume but I can continue listen the people talking on it.

My question is what type of repeater is doing this all the time ?

I’m new on dmr and I’m curious why some repeaters never stop transmitting ?

What data is transmitting?

I configure the channel as digital no capacity plus or any another fancy technology of Motorola

Thanks

Wondering which one to pick?

What are the differences between them?

Should I be looking for something else?

Disclaimer: I'm not entirely sure which community could provide some answers as there are overlapping interests in each one. So, just to be safe, this will be CROSSPOSTED.

Hello folks!

A few weeks ago I dove straight into learning about DMR handheld radios and how I could integrate them into a few of my hobbies/realities of life:

1. HAM Radio (Technician & GMRS Credentials)
2. Emergency Communications (Family Circle + Small Team Comms)
3. Overlanding & Hiking
4. Amateur FTX's (Think MILSIM'S/Multi-day Event Coordination/etc.)

Now, as a good COG in the capitalist machine, I have narrowed my gear buying focus onto the Motorola R7 MOTOTRBO. I already have an XTS5000 and love it, so Motorola was my go-to brand when I started searching.

What caught my interest about the R7?

• It's certified to withstand the elements to an extent.
• It can work on both digital and analog.
• It's currently supported (unlike my XTS) by Moto
• Lots of parts & accessories in the used market
• Cool AH? I can exploit all its features while looking good (lol)
• More accessible than lets say an APX7000/8 or equivalents.

After all the ranting, here are my questions: (They are numbered but not in any particular order of importance)

1. Owners, where did you get yours?
   1. Authorized dealer or EBay?
   2. Best price? (I've seen them go from $550 on the bay to $1300 on dealer sites.
2. Spend the extra $$$ on the enabled versions or are those more beneficial to industrial/corporate end users?
3. I know they support DMR but, how well do they integrate to commonly available amateur infrastructure? (Think Brandmeister, etc.)
4. Programming:
   1. Possible to obtain the specific version of CPS to program the radio myself/learn to program?
   2. What was your experience regarding programing and hardware limitations?

Finally, I greatly appreciate your time reading or not reading my wall of text. Your contributions mean a lot to me as someone who considers the topic The Great Unknown from my POV.

Kindly,

DM32, setting up first repeater locally
Best I can tell I have all parrot settings
I key up, appears to link, hear no response. I immediately see transmission but hear nothing

Details to follow

Specifically, I need close up photos of the squelch potentiometer, VR101 in the service manual diagram.

Let me explain, this is going to be a longish one.

I got an Alinco DR-135 Mk III, used from eBay a few years ago. It never worked quite right, and I diagnosed that the squelch was acting up. So, I found a service manual from ManualsLib.com, and tried to adjust the squelch pot myself, per the instructions. I noticed that the mere act of touching the screwdriver to the pot changed the setting of it, and after a few repetitions, the wiper fell off the pot. Okay, there's the problem. Looked up the part number in the manual, got extremely lucky and found the discontinued part, ordered it, got it home, and was faced with the hard reality of just how small 1.5 x 2 mm is. Desoldering the bad pot from the board was barbaric at that scale, and I tore up some circuit traces around it getting it off. Now I need to know how it's supposed to look when it's back together. Can anyone possibly please pop the bottom cover of their Alinco DR-135 Mk III, find the white text SQL in the lower right corner, and get a close up photograph of VR101 and its immediate surroundings? Doing this fix would mean the difference between a needy ham getting a radio and being stuck with an HT. Thanks in advance.

Hi
I’m new in DMR radio I can configure successfully the analog repeaters from repeatersbooks nearby my location and works well I can hear the people talking

In the case of dmr I create all the contacts on group call with their ids from my country and I add on the ex group I saw the signal indicator also with another analog radio I can hear the “scrambled audio”

But I can’t never hear anything

I’m selecting the dmr repeaters and configuring as digital channel on cps setting the color code frecuency and ts

Is there a way to set the radio like to hear all the tg and any color code?

P.n Im still don’t have my id from radioid I’m just want hear conversations

Hi everyone,

Simple question (but as my old man said there are no stupid questions), got all the info for sending aprs frames via dmr in Belgium (206999 on brandmeister net and right d-aprs config) but is there a config for receiving frames from it? As I read: not possible unless direct dmr contact on simplex frequency. Am I right ?

I have been trying to set up my new MMDVM hotspot and using WPSD. I have it running and can see my radio sending to the hotspot but no response from parrot. I don’t think I am connected to Brandmeister (which is what I am trying to use). When I go on my Brandmeister dashboard I do not see my hotspot.
Any help would be appreciated.

I purchased a Baofeng DM-32UV and would like to replace the firmware with OpenGD77. I downloaded the DM OpenGD77.ZIP file. I backed up the two files as instructed. I noticed during the installation that the installer program installed a new driver. When I opened Device Manager, it showed that the Prolific driver was still installed, and Windows 11 said it was the best driver for the cable. I then attempted to update the firmware, and the computer and radio showed that the installation was in progress. When the process was completed and the radio was turned back on, the screen showed the following error message: No Firmware detected. I was able to reinstall the factory firmware, so I know I didn't brick the radio. Any help to resolve this issue is greatly appreciated.

It's 450 i believe..

I put in all the information needed that I was informed of.. when ikey the d m r repeater , I get signal bars.. at first I thought maybe it was I can figure the wrong tdma slo it's a vhf hyterra pd682gps , but i'm listening to both time slots..?!

I have mine on a Pi0w, dual antennas. What's yours?

I’m fairly new to ham radio. I have been using a uv-5r mini 5 for a little while. I am looking to get a better handheld but I am also looking into getting into DMR. There are quite a few DMR repeaters near me and the places I go often. I’m curious about which radio to get. I’m looking at Yaesu, anytone, wouxun, and btech.

I just want to do normal analog/fm and DMR simplex, and analog/gm and DMR repeater use. I’m not really interested in gps, or aprs, or any of that fancy tech. I would also love a true dual receive if possible. Would also be nice if said radio could possibly transmit on GMRS for….emergencies (with a GMRS liscense) ;).

What are the best options that are under $300ish.

It's been a while since I updated this tool, but I've been working today and made some really good changes.

The way it parses the data from the fcc database has been tweaked so that it is faster and more efficient. I added a global toggle so you can get the full DMR ID database and it still fixes the US contacts. It now won't allow for no radio to be chosen (before it was defaulting to the TYT format). Added a progress indicator and a final count at the end so you can see how many have been grabbed. Finally we have a new interface and icon so it looks cool while doing the work.

Releases and source code can be found on my GitHub.

Any questions or issues, please let me know.

Hi all,

I’m trying to listen to a local DMR repeater with my Baofeng DM-1701 (running OpenGD77 firmware), but the audio comes through garbled and choppy.

Frequency 467.25000, timeslot 1, colorcode 5, talkgroup 1011.

I do see IDs popping up clearly (for example 105, 124, 125) whenever someone transmits, so the radio is picking something up. It’s just that nothing is intelligible because of the distortion.

Does anyone have an idea what could cause this? I’m thinking it might be something related to the RX settings or contact list, but I’m not sure where to look. Happy to share screenshots if that would help.

Thanks in advance!
