Hello
I did a check on my radio
from repeater 145 kilometers
the radio works correctly and there are no problems
Baofeng DM-X DMR
Привет. Всех с наступающим праздником!) Вопрос: Имеются две dm-x, но у обеих слабая чувствительность микрофонов. Можно, как нибудь программно добавить уровень? Не удобно близко говорить или орать в микрофон. Если делать громкость на максимум, то системные звуки, до инфаркта доведут))) Спасибо)
Hey. All with the upcoming holiday!) Question: There are two dm-x, but both have a weak sensitivity of microphones. Can I add a level programmatically? It is not convenient to talk closely or yell into the microphone. If you make the volume to maximum, then the system sounds will bring to a heart attack))) Thank you)
Hello and Happy New Year. Be healthy and happy!
And what’s the difference between the two microphones? Probably one is built into the radio and the other is on the switch (headphones, handset …) What is the value for better amplification?
The flashlight works if you program it on some of the 3 programmable buttons. But. If you have the gps version of the PCB, the gps antenna is below the circle. There are factory openings on the board under the antenna for soldering the flashlight. With a little reworking, an ordinary LED with appropriate resistance can be mounted. For example: program the upper long-pressed button to activate the LED. Note that the voltage is about 7.4 V

Yes, i saw, thanks! And microusb not comunicate with pc. Cps 2.22 Can’t download audio records or alternate charging battery as seller and other site describes.
I’m not sure what you mean by “microusb not com with pc. 2.22”. Would you specify?
Thanks.
sir can post it again the firmware’
One of this uploader and firmware works for me well:

The CPS was never able to download the recordings. But it should be able to communicate using standard micro USB cable.
If you wish to download the recordings and are familiar with Python (preferably on Linux), you can use my tool ( md1702-rec) which is linked earlier in this thread. But the recordings are stored in native DMR codec format, so you would need to build and use my patched version of DSD to decode them (the official one unfortunately does not).

Folks, how do i download audio records on my pc ? Microusb cable and the Kenwood-plug-cable from my RD-5R working both SAME good (NO Prolific-drivers needed) for programming (read/write to radio) - still can get any audio recorded files in my pc? Any clues? (Connect in radio one OR the another cable, not together in the same time!)
The link and some information is mentioned in post #108, but please note one thing - the communication is really slow (by design of the communication protocol). To read all 16 MiB of the flash memory will take over an hour. So based on the amount of recordings, it may take several minutes or more to download them.

It’s trivial to translate the Chinese parts of the UI in lang_en.lng and replace in the Data directory but since I’ve already done it I might as well share. Unfortunately it doesn’t necessarily make it any more clear 
My radio came with the 2.2.22 firmware and I’m almost done reversing the channel portion of the codeplug data. Maybe we can combine our work and create a new and open-source CPS.
2 things I kind of hate about this radio: 1) the volume control (it’s out of control :P) and 2) the mic gain.
I think I may need to do a hardware mod to tame the volume and I’ve tried the MIC settings in CPS it seems -12 is the loudest but it’s still too quiet in my opinion.

Well, nice you transtlate this. Question: if 1846 is a crystal - mmdvm boards (pistar hotspots) have “14.7456 MHz TCXO” and “12.288 MHz TCXO” values (for data speed %) . What should be the right value here?
And i thing your battery value (in the left side) is wrong. Must be 4 digits!
Why overall “127” values??? Your low/high power is dangerous…
“255” is for “not available/nothing here”. I think should remains “255”.
This are just the default values used by the MD software, not values from my radio. I think you’re focused on the wrong part of the picture
Yes, the “default MD values” are not calibrated values for the radio (to write in).
Do not paste this values, kids are playing arround - kaboum !!!
How can i manually edit frequencies ? Can’t find editable VFO’s…
