Hi Galen,
Does the BF-T20 work with the factory BF-888S programming software? I would suggest that you try the factory programming software first. If that works, then that would rule out many programming cable issues. If it doesn't work, then you most likely have a programming cable/driver/connection issue.
Also, the BF-T20 looks more like a Retevis RT22 style radio (with many variants such as WLN KD-C1) than a BF-888. Assuming that you don't have a programming cable issue, I would try Retevis RT22 or similar model.
After a little googling, I download the "factory" BF-T20 programming software from the "ABREE website's Download area":https://www.abbree.cn/download/. I see that the installer says "Welcome to the installer for KD-C1 1.0", so my guess above should be correct. You would program the Baofeng BF-T20 using the WLN / KD-C1 vendor/model selections. Confirm this and I will add the BF-T20 to the CHIRP Supported Radio Models list on the CHIRP home page.

Thank you,
I got rid of my last windows install this morning,
Only Linux now.
On chirp I did try all BF & Retevis download options, no luck
Cable has worked recently.

The same settings also apply to the W31, could we perhaps get those notes added to the supported radios list?

There appears to be at least 2 versions of the Baofeng BF-T20.
1 A 16-channel UHF model (full-band TX/RX)
2 A 22-channel FRS model (with FCC ID and limited to only FRS frequencies by firmware)
I have developed test drivers for each and have attached them to this issue. Actually the second test driver ( radtel_t18 - t20_frs.py ) supports both radio models. Please test and report back your results. Here is how: LoadingTestModules

I am working with a Jucjet F-20 (from Amazon) which appears to be a clone of the BF-T20FRS, with 22 channels. It works fine with T20_FRS module.
With tiny modification of the driver (change 22 to 32), I can access and load data into the radio for 32 channels. However, the radio will still only annunciate 22 channels, so the extra 10 channels can't be used (yet).
I am working on figuring out how to activate those last ten channels. I was able to do this with the Retevis RT22S, but this change was done via the factory software and a modification to its setting.ini file. Now I have to figure out (a) what changed and (b) how to change it.
