Hi Gleen,

You mentioned that Windows 10 does not recognize your cable maybe this is the root of the problem, well there is a known bug with the prolific cables (roughly 90% of the cables out there) and Windows updating the driver to the latest version that will render the cable unusable, you have to apply a trick to downgrade the driver version if it's the case.

Please check the miklor site (www.miklor.com/COM/UV_Drivers.php) for instructions on how to do that, here on the wiki there is also a lot of info about it, just search for "prolific driver"

Then you mention two different radios, the QYT KT8900R in the issue subject that is not supported in Chirp by now, we support the QYT KT-8900 not ending in "R" model (we need a serial capture to get your radio supported, see this post about how to do it: http://chirp.danplanet.com/issues/2673#note-38) and you also mention the TYT TH-8900R that is also not supported by chirp (unless you want to say the TYT TH-9800)

73.

Thanks to Mattew Mirabito for the logs, I have a dev version for you to test with support for this particular radio, please test it and report back +any+ issues.

To try it you must follow this steps:

save the "btech.py" file attached to this post to where you keep your chirp radio image files¶

click "Help"¶

enable "Enable Developer Functions"¶

click "File"¶

click "Load Module"¶

find and load the "btech.py" file that was saved in step 1¶

Note: This special test module only temporarily changes your CHIRP. You must load this module every time you load CHIRP.

I need your success or failure story to validate this solution, I will need the debug.log of the failure stories; In this link you will find how to find the debug.log file:

http://chirp.danplanet.com/projects/chirp/wiki/How_To_Report_Issues

Note: The debug.log is configured to full debug power, so it will be huge compared to a normal one, please zip it before uploading.

Developer version of the btech.py posted with the above post was deleted because it contains a bug, please try this one instead.

Sorry for the inconvenience.

Tested, patched and in the daily by now, so this item will be marked as resolved.

And after 2 months with no issues it's Closed now.
