I read the instructions above:


I just purchased a QYT KT-8900D from amazon, and using current Windows 10 and the OEM programming cable.
This behavior is consistent between 3 different (Windows 10) computers.

When I attempt to Download from Radio, setting to the COM port showing a prolific chipset in Device Manager, and setting QYT and KT-8900D in the model selection, and then powering up the unit when indicated by the dialog, after a very short window saying "Identifying the radio...", my radio powers off and a dialog pops up saying "Radio identification failed"

Oh shoot, I missed the Model affected field. This appears to only affect this radio (QYT KT-8900D) ;
my BTech and Baofengs have always worked flawlessly with CHIRP

Hi Josh,

Your radio has an MCU version that CHIRP is not aware of yet. I have attached a test driver module that includes the new MCU version. The following explains you to load the test driver module for testing.

1 save the attached "" test driver module to a convenient location

Important: left click the file name and then click the "download" link on the page that loads.

2 open CHIRP
3 click "Help" in the menu bar and enable "Enable Developer Functions"
4 click "File" in the menu bar and select "Load Module" in the list of selections
5 locate and load the file that was saved in step 1

The CHIRP background should now be red. Attempt to download from your radio. If it works (it should), attached the downloaded CHIRP Radio Images (*.img) file to this issue.

Note: This test driver module does not permanently change your CHIRP installation. If you close CHIRP and later on need to access your radio, you will have to load this test driver first.

I will develop and submit a formal patch once I see that the test driver module is working for you.

Perfect, thanks!

After loading the module, I was able to read from and write to my new radio.

Thanks a bunch and have a great day!
