Description

I installed the new 4/2/16 build and tried it with my QYT KT8900. It took many, many tries to download from the radio - 20 tries, 1 download. At no point could I upload to the radio. When connecting, the radio would reboot and then Chirp would show an error after the identifying blue bar.
Windows 7
Windows XP
Prolific drivers 1.3 to current
Tried changing port bits/sec
Uninstalled, rebooted, installed, etc. Both with Chirp and the drivers. Verified driver version each try.
Prolific cable that works with the original QYT software every time I tried it.

[PATCH][KT8900] Comment about old versions of KT8900 in the UI, fixes #3539

All points that the QYT KT8900 is the main OEM model, and there are two
variants of it, from the prespective of the communication dance:

  • One is with just the ID and right to the down/up process (clone of WACCOM
    Mini8900)
  • The other (is the default now) with a second id read & a extra step on the
    upload process.

As both uses different communications steps we can't put them both under the
same case, fortunately the "older" model has a clone in the WACCOM Mini8900.

We put here a notice on the failure to read a KT8900 to warn the users to try
the WACCOM Mini8900 instead.

Hi Bob,

Thanks for the report, I need more data to try to know what's going on, check you email for instructions to make some tests for me.

Updated by Pavel Milanes about 3 years ago

There is any chance that your QYT radio is a QYT KT8900*R*?

If so it's not supported, but with your help we can make it happen.

Hi Bob,

Today I sent some patches to the devel queue that must address the problems you are describing here, please test the next build of chirp and repport back.

i downloaded the newest version of chirp and its still showing "radio identification failed" and it restarts radio. I was hoping this new version would fix this. Radio is a kt-8900 and not the "r" model.

ok…. from my end of things it still does not work as a qyt kt8900…. but it does work if I download from radio as a sainsonic GT-890. also uploads. It did crash when I tried to copy and past 20 channels from another file but did work doing them one at a time.

Updated by Pavel Milanes about 3 years ago

Hi Shelby,

The changes in that alpha driver are already on the Chirp daily, interesting the thing you mentions about the KT8900 working as a GT-890, that can mean that we have more than one version of the KT8900, I'm very interested on a serial capture from your radios with the OEM software.

You can find a tutorial about how to do that here: http://chirp.danplanet.com/attachments/2257/how%20to%20portmon.doc

If you want right support for your radio I need that serial captures to make it happen, and in the process you can help others with the same problem.

Sorry, I have been trying for 1.5 hours and I can get no readings at all on portmon. I am using a Windows 7 and XP 32 bit machines. The factory software is working fine, downloading, uploading, etc. I followed your directions to the letter and nothing is happening on portmon, no text, no response. I hope someone else has better luck.

Updated by Bob Belbeck about 3 years ago

Thanks for the help Pavel! Attached are the requested portmon files for my new radio which won't work with Chirp. I have zipped all 3 files: Download, upload, and the data file in qyt.zip

Hi to all,

Attached is the development version of the btech driver for you to test before I include it on the main Chirp repository, so I'm greatly interested on feedback about it.

Thanks to the users input I got over the weekend about 4 serial logs, I had identified 3 new variants of the QYT KT8900

One is a development of the QYT with it's own particular ID
Other is a clone of the Sainsonic GT-890 (or vice versa, who knows it for shure?)
And the other is a clone of the Waccom Mini-8900.

This attached driver know the default and the first two, the last one has a slightly different comm protocol and the driver has now a warning for the users about if this is not working "please use the Waccom Mini-8900 instead and it may work..."

How to use it:
  • save the "btech.py" file 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 up on the failure stories...

PS: This driver has transparent support for the the second version of the Sainsonic GT-890 also.

73 and enjoy, Pavel CO7WT.

Pavel, Loaded the btech.py module. Radio successfully programs both of my radios as a SainSonic GT-890.

Tried reading from the radio after loading the btech.py modue. As a QYT KT8900 it tells me it can't go into clone mode, this time with the longer message suggesting I try the Waccom driver. The Waccom gives me the "error reading data from radio" again.
I should mention that it will work using the factory software (UV_CPS v1.02 from Miklor.com), so that at least verifies my cable and connections are OK :)

Updated by Michael Dodds about 3 years ago

Also, if it's any help, the factory software restarts the radio on program startup, then restarts it again when it is done reading data. Chirp (in the Waccom setting) causes no reaction from the radio until I try to read, then it immediately restarts and gives me the error message.
Chirp set for the QYT causes no reaction at all, I just get the clone mode error.

Updated by Pavel Milanes about 3 years ago

Maybe you have a unknown variant.

I need a debug.log file (search the wiki to find how to find it) to have a clue about your particular problem.

Please fire Chirp, load the file and try to download (it will give you an error, I known) and look for the debug.log and upload it to this issue.

Here ya go.

Updated by Pavel Milanes about 3 years ago

Hi Michael.

Your KT8900 is a Waccom Mini-8900 clone and it's positively identified by the driver as such, but...

The Waccom Mini-8900 radios (and it's clones) has a unknown problem under Linux, please try it under windows until we can figure out how to fix the bug of the waccom in linux.

Updated by Michael Dodds about 3 years ago

OK. However I get the same error in Windows also. Want me to send the debug log from there?

Hi,
Just got Btech 2501 and get the "radio can't be identified" thing on Windows 7. Also, I can't load btech.py, says line 1 invalid text. Tried every radio as suggested. Thanks.

Hi Joe, this is not the issue for the Btech 2501 (that will be the issue #3015)

FYI there is a patch for the new wave of BTECHs (Gen3) in the devel queue, you may have one of those newer units.

Sorry, not line 1 invalid text says "invalid syntax line 1

  • Status changed from In Progress to Feedback

You can't be downloading the btech.py file properly. DO NOT right-click on it and choose "Save link as...". This will save the HTML of a web page that displays the file to a file called btech.py. Since it isn't a Python file, syntax errors would be expected.

Instead, (left) click on the btech.py hypertext link then follow the prompts to download it.

  • Status changed from Feedback to Resolved

The main issue on this thread is resolved, then a side issue was identified: the problem with the waccom mini and it's clones in linux, that issue was solved later on issue #3993.

So I will mark this as solved and close it.
