Baofeng DM-X DMR

Hi
I bought last september at JARL Ham Fair in Tokyo, a baofeng dm1702 gps ver 02.02.023 and cps 1.00.66 . Unlike some post that I have read, the gps works very well and the aprs is possible to configure from the moment you have the right to use it (which is not yet the case for me ). I have, however, two small problems with:

  • The microphone modulation level was far too low. So I changed in the parameters of the talkie, going from -12dB to 0. From now on, I’m better heard.
  • I have an unsolved problem however … When I put myself on the frequency of a DMR relay (good frequency, good cc and ts), I receive absolutely nothing and the LED flashes green faster than when the scan is operational. What setting should I change to be able to listen properly? I saw in the setup that you could choose the bandwidth and the “dual capacity” but I don’t know yet what that means at baofeng.
    Thank you for your help.
    Jeff … and sorry for my poor English

HEllo
who will tell you how to enable the auto-detection function
contacts
for example in the list

I do not understand what you are asking about. If you mean so that contact number for a single person is displayed, you must change the Call type from Group Call to Private Call. Did you ask about that?

Hello .
If the ID and its subscriber name is inserted into the directory of the receiving radio, they will be displayed to the recipient, whether it is a personal or group conversation. It also matters if the transmitting subscriber has entered his radio in addition to his ID and name. When there is a group QSO, the ID is displayed immediately and the name is delayed (2-3 seconds). In my opinion, this delay is due to the time of signal processing and data visualization. Recently, I learned that character encoding is also important - whether they are manually entered into the radio or with software under win. 7 or win. 10.

Hi
I just want to ask. Do you know what the offer is? When you turn on a station while holding down the Ptt button and the button SK2 below it. What is this setting?

Hello.
This can be said by someone who knows Chinese. But as far as I know, this is test mode. It is probably the same (functionality) as in the MD> Program> Online Test menu. Clarification: You must use CPS2_extra_menus.exe to access this menu.

Hello
Does anyone know if the Baofeng DM-X is in fact the same radio as Retevis RT72?

It seems to be the same design menu (viewed from pictures on the Internet). The software it works with is similar. For the idea, I installed and tried to connect my walkie talkie. It just blinked and restarted. Couldn’t connect.

You should probably use English here, e.g. nip does not speak Czech.
BTW, the secret menu, its code and what it generally does is mentioned earlier in this thread.

CZ: Dobrý den pane Jícho, v tomto fóru by bylo vhodné použít angličtinu, jinak Vám uživatelé nebudou rozumět. To tajné menu se používá na testování zařízení, a nastavení výstupního výkonu, korekce frekvence CTCSS apod. Je to zmíněno (anglicky) zhruba v první 1/3 diskuze.

Hello .
Sorry, that was a mistake …Google translate

Hello everyone finally found problem in the GPS in this Radio, 1 year later to try to work, not need none settings for work, only need open you radio and found GPS antena located under the circle and remove clean disconnect and Connect again and finaly work Take position after two minutes. Open you radio with carefull, first step is remove the circle metal around volume and antena, open slowly

New DM-X owner. I wonder if anyone else has this issue. If I leave the radio monitoring my hotspot for any length of time, eventually it will get stuck on a call. Screen frozen, green light on, no audio. If I hit channel up for down, or either of the menu buttons, it responds fine and resumes receiving. Firmware 2.02.22

Hello everyone!
I have a few problems with my radio DM1702.

  1. GPS is not working (от слова совсем).
  2. Bug with receiving analog signal (LED indicates that the signal is receiving, but speaker is silent; when I open the squelch by key and then close again - receiving is started; after rebooting problem repeats).
    On main board I see “DM-1702-V1.3”

Hi Folks! Coluld you give me a passwords to “Test” and “Online test”? I tried to use PIN 374612 from “Embedded Message” but didn’t work. Thx

Hi you :grinning:, Look here post 18 Baofeng DM-X DMR - #19 by pm_cz For others…

Thanks Buddy. I am not an IT specialist but I found it :wink: 66660501.

Hi sq4q. I’m not an IT specialist either. With the help of pm_cz and my knowledge of Linux OS, I was able to cope with password extraction.

Thanks again pm_cz :handshake:

Hi everyone, i just carrefully read this entire thread, very interesting.
It seem my DM-X had a new firmware (v1.4) :

Also TYT380/390 Seem to have a very close hardware …

@pm_cz have already make à great work with his toolset !
I guess we need to find a solution or réuse 380’s solutions to upload customized firmwares.

Hello, no it is standard 2.02.022 version, the existing firmware (actually you may enter anything you want to into serial number and other fields in extended CPS settings).

Concerning the customized firmwares, I am quite sceptical to that. I spent quite a lot of time with Ghidra tool last summer trying to identify the individual functions, but a lot of things is different from older MD380 radios in the code (the memory layout, GUI calls, etc.) so the patches would not be applicable. Plus I had to start from scratch for 2.02.019 again and I would have for 2.02.022 as well (although some functions were easy to identify). On the other hand, many things have been integrated to the firmware, like the possibility to turn off the Call/Group matching. The most pressing would probably be the CSV contacts instead of some space used for recordings and I would probably not be able to implement that.

Edit: to clarify why, besides all other programming issues, the communication protocol with the radio is EXTREMELY slow, so the upload of CSV contacts would take about an hour each time.

Hi

I have DM-X with firmware 2.02.019 and I would like to upgrade. I have following:

  • File from 1702_02_v22-encrypted-CPS-1.0.78.zip - 1702_02_v22.bin* - New CPS 1.0.78
  • File from fw_2.2.22-decrypted.zip - 1702_v02.02.022.bin* - Old CPS 1.0.66, Python DFU tool

What version 2.02.022 is recommended to load “encrypted” or “decrypted”?

I will be grateful for suggestions
