Chirp doesn't work with Retevis RT24
Just bought a pair of these radios and tried using Chirp. I receive the cannot download block 0008 error message. Prolific drivers ok and Retevis's own software works ok, just wondering why Chirp doesn't.
Using Win 11 in case this may be an issue.
Debug file and 2 pics attached.
Thank you for adding the debug.log file. Unfortunately it doesn't provide any more information that you already explained in your original description of the problem.
The RT24 was never directly reversed engineered by a CHIRP developer. Someone opened a ticket about 2 years ago saying the the Radioddity R2 Vendor/Model selection worked as-is for the RT24 so the RT24 was added to CHIRP as an alias or the Radioddity R2. I have sent a note to Retevis to see if they would donate an RT24, RT24V or its close cousin the H777S in a hope that having the radio would help with diagnosing the problem.
So you do have already have the older Prolific v22.214.171.124 driver installed in your Windows 11 computer? The latest driver provided to Microsoft and automatically installed when a Prolific chip is detected by Win11 now refuses to work with the more recent PL2303TA chip like it has been doing for the last decade with older PL2303XA chip. It has become so stubborn that it won't even assign a COM port any more. It now takes a driver version 126.96.36.199 or older to work properly (v188.8.131.52 recommended).

Thanks for the reply. I know about the Prolific issues and have 3.8.39 installed, previously .25 and they work fine with my Yaesu FTM-100. Windows did update to 3.9.3 which of course doesn't work. This is a well known issue due to Chinese knock offs of the chipset.
I tried Radioddity R2, doesn't work.
I hope you receive a response from Retevis.

Yes, the v184.108.40.206 driver works with the newer PL232TA chip but not the PL232XA chip that has been end-of-life (EOL) for over 10 years. But recently the PL232TA chip also went EOL. So the v220.127.116.11 and newer drivers have dropped support for the PL232TA as well. I just use the v18.104.22.168 driver because it works with both versions of the EOL Prolific chips. If I only used CHIRP I could use the v22.214.171.124 or v126.96.36.199 drivers, but they have issues with some of the OEM programming software from around 10 years ago.
I did get a reply from Retevis. We are still negotiating the details, but it looks like I will be getting the RT24 (PMR), RT24V (FreeNet) and H777S (FRS) radio models to use for troubleshooting this issue.
