The Radioddity DB25-G is not a CHIRP supported radio model. Only the DB25 (no G) is. What error message do you get? Attach a debug.log file.

Hello Jim,
Thank you for the response. Using as some suggested for the DB-25 Vendor : QYT Model: KT8900D , The radio says cloning , the radio clicks and turns off and then turns back on and gives an error message stating the program was unsuccessful. I've been out of the Ham business for quite sometime, as I talked on the radio all day in my former career. Now that I'm retired, I'm pretty much starting over. I was just trying to help some friends with their new radio ; add some extra listening rx and features. I appreciate your time. A Rio W7DGM

Open CHIRP (starts a new debug.log file)
Attempt the download using KT8900D (to cause the error)
Close CHIRP (to close the debug.log file)
Attach the debug.log file to this issue. Maybe I can see what the difference is.

Thank you for the debug.log file. Now some progress can be made!
As I was hoping, the DB25-G has an MCU version that CHIRP doesn't know about. I have created a test driver module to see if you can successfully download from your radio. Here is how you use it.
- Download the db25-g_test_#1.py test driver module and save it to a convenient location.
Note: Be sure to left-click the link and then click the download link near the top of the page that loads. Right-clicking the link to download the test driver module will not work.
- Load CHIRP
- Click Help in the menu bar and enable Enable Developer Functions
- Click File -> Load Module to locate and load the test driver module that was saved in step 1
At this point CHIRP will have a red background to indicate that it is running with an external driver module loaded. With any luck, you should now be able to download from your radio. If successful, please save the newly created tab, unedited, to a CHIRP Radio Images (*.img) file and attach it to this issue so I can use it for further development. If the download fails, close CHIRP and add the debug.log file for me to examine.

Whoops! I put the test code under KT7900D, instead of KT8900D (which would work for this initial testing). Here is a replacement test driver module with the test code moved to KT8900D.

Jim,
Attached are the two files requested.
Mic Gain is a numeric value between 0 and 127. Thus the two file names.
Mic Gain is function menu #4 within the radio itself.

Yes. I realized my "ON"/"OFF" mistake once I added my reply. I was hoping you would realize the mistake and get me what I needed anyway. You did. Thanks.
Hope this helps.
Yes.
Now I have some questions.
The OEM software shows channels 8-14 as being blank. Did you add channels 8-14 yourself or were they already present in the radio when you got it?
If channels 8-14 were already present, do they transmit or are they receive only?
Do the channels 190-199 (NOAA WX Radio) transmit or are they receive only?
Do the channels that you added above 30 transmit or are they receive only?
The factory DB25-G software doesn't include a setting for Menu 4 (M-GAIN). It also doesn't include a setting for Menu 57 (PONYEY). Would you include a pair of "images" with this setting set to OFF/ON?
Thanks,

Either... add 3 images with the only difference being the TXP setting on a single channel
or... add a single image with 3 adjacent channels that are identical except for the TXP setting.

Actually, get images requested above using this latest test driver module: db25-g_test_#3.py. This should provide a CHIRP Radio Images (@@.img) file with the *Radioddity DB25-G metadata that I will require for further testing.
It is selected using Vendor: Radioddity / Model: DB25-G.

Ron,
Thank you for the feedback and the files. They are most helpful.
The attached temporary test driver module (db25-d_test_#4.py) includes the Mic gain and Auto power-on settings.
Also note that I have gained enough confidence in the settings that I have decided to enable the ability to upload back to the radio.
I have not done anything to support the 3 TX power levels yet. Is there any way that you can...
- verify that the radio actually supports 3 TX power levels (measure with a watt meter or at a minimum key up on all 3 power levels to see if the radio puts out RF on all 3 choices)?
- provide the measured TX power levels (or at least a guesstimate)? The manual shows 5W/25W. So it could be {something}W/5W/25W or 5W/{something}W/25W, etc.
Also would you check to see if you were to copy 1 or more of the 22 original GMRS channels to any of the other channels (31-189), will a valid GMRS frequency on other than the original 22 channels TX or is TX disabled on all but the original channels 1-7 and 15-30? I've got a Retevis radio that you can program a valid GMRS frequency on any of the 99 channels and it will transmit. But any other frequency and it will be TX disabled. Handy for having duplicate repeater frequencies with different PL and DPL tones.
On the UV-5G (a Baofeng handheld GMRS radio sold by Radioddity), I programmed CHIRP to automatically set Duplex = "off" to show TX disabled on the channel to match how it behaves in the radio. I think it should be done the same on the DB25-G. What are your thoughts?

Jim,
I did some testing with my digital wattmeter into my external antenna with a SWR of about 1.3:1
Low = 7.1 watts
Medium = 12.9 watts
High = 18.4 watts
Yes, if you copy a GMRS frequency to ANY of the other memories, it will TX on that channel. I have done this with several local repeaters on the same frequency but with different tones.
The radio will not TX on anything other than GMRS frequencies. And it will not TX on the low-power GMRS channels 8 thru 14.
I believe Duplex should be set to ON. This is how the radio behaves with most GMRS frequencies. I am using the radio for purposes it was not intended. I need to monitor some frequencies other than GMRS ones. The radio lets me monitor four channels at the same time.
Hope this helps.

Jim,
Another interesting observation...
On the limited-power GMRS channels 1 thru 7, the radio puts out 7.2 watts regardless of the power settings. All three power settings put out 7.2 watts. This complies with the regulations on power output.

Jim,
More testing...
I was able to download the radio into CHIRP. I then modified several parameters and channels. I then uploaded from CHIRP to the radio.
The upload was very slow but was successful.
Interestingly, any channel with Power=Low in CHIRP uploaded to the radio as Power=Medium.
Hope some of this helps.

Perfect. Just what I was looking for.

Nice.

All as it should be.

Right. Any channel using the same frequencies as channels 1-7 and 15-22 would be Duplex = "(None)" {which in CHIRP means simplex}, any channels using the same frequencies as channels 23-30 would be Duplex = "+" and Offset = "5.000000" {repeaters} and any channels using the same channel 8-14 frequencies and frequencies other than GMRS frequencies would be Duplex = "off" {which in CHIRP means TX disabled}. Nothing about how the radio behaves would be changed. The memory editor would just be updated to have what it displays match the way the radio already behaves.
Hope this helps.
Very much so.
Thank you,

Unfortunately this is how this driver behaves.

Yes. Until I can come up with updated code it is...
High in radio is High in CHIRP
Medium in radio is Low in CHIRP
Low in radio is unavailable in CHIRP
This will be the next thing I try to figure out.
Hope some of this helps.
Yes. It all does. Thanks!

Please check out these updates and provide feedback.
db25-g_test_#5.py
Adds support for 3 transmit power levels (High/Mid/Low).
Note: I called the middle power level "Mid" only because most drivers with 3 power levels call it that. I believe you used "Med" above, so what are the choices in the menu of your radio? Do you have a preference (Mid vs. Med)?
db25-g_test_#6.py
Adds validation to GMRS channels 1-30 so CHIRP displays the per channel values that match how the radio behaves.
- 1-7: Duplex = "(None)" (simplex only), Power = Low (low power only)
- 8-14: Duplex = "off" (TX disabled, RX only)
- 15-22: Duplex = "(None)" (simplex only)
- 23-30: Duplex = "+", Offset = "5.000000" (repeater only)
Adds validation to channels 0 and 31-199 so CHIRP displays the per channel values that match how the radio behaves.
- GMRS frequencies follow the rules above
- All other frequencies: Duplex = "off" (TX disabled, RX only)

Jim,
Both of these updates seem to work just fine. I did experience one glitch where the power settings for memory 190-199 were written to memory 50-59. It was a one time thing that I can not get to repeat.
I am impressed at how well the software works. And it uploaded to the radio faster today than yesterday. You are my hero.
I will let you know if I run across anything else.

I'm watching this case and have great interest in this. Where can I get the latest update that has this functionality for the DB25-G in it? I have a friend that just ordered this device and will be helping him configure it. I see the IMG files and the PY files, I loaded the IMG file in the current version of CHIRP to poke around in the config but not sure what radio profile to use to get it to upload. I have several other radios that I'm currently using with CHIRP.

There is no CHIRP daily build with this functionality. This is a work in process. Nothing has been submitted for inclusion to CHIRP yet.

You don't choose a "radio profile" when uploading. The radio Vendor/Model that was used when the "image" was created is embedded into the image's metadata. When uploading, these parameters are automatically selected and cannot be changed.
Also, none of the Radioddity DB25-G images attached to this issue will load into the "current version of CHIRP" without first loading one of the test driver modules (@#3-#6@). At this point you should be using db25-g_test_#5.py or db25-g_test_#6.py and images beginning with "Radioddity_DB25-G" for testing.
Instructions for how to do this is in comment @#5@ above (just substitute the current test driver module for "db25-g_test_#1.py" in the instructions.

You already have it. It is called db25-g_test_#6.py
db25-g_test_#5.py takes db25-g_test_#4.py and adds support for 3 TX power levels
db25-g_test_#6.py takes db25-g_test_#5.py and adds validation for GMRS channels and frequencies
It wouldn't make sense to support only 2 TX power levels since you have conclusively proven that the radio supports 3 TX power levels.

If you have any BTech, QYT or other supported variants, make sure I didn't break anything adding the DB25-G support. Otherwise, just let me know if anything doesn't work as expected. I don't have a DB25-G so I have had to work solely from downloaded "images" and very helpful feedback from users.

Jim,
Sorry, I do not have any of those other radios so I can not confirm if those were affected.
Just tried it out. Was able to download from the radio, make changes and upload to the radio.
Power level setting shows low, mid and high.
Repeaters have duplex at "+" and offset is "5.00000".
So far, so good. It does take a few minutes to upload to the radio. Not sure if that's normal with this family of radios but uploading is faster with the programning software from Radioddity.
If there's anything else you want me to check, let me know.
