CHIRP

Not sure how that possibly makes any sense, given that choosing something from the drop-down just fills in a text string. However, without a debug.log I can't/won't investigate any further. Instructions on how to fill out useful bug reports are in the documentation.

Problem: TYT TH-UV3R , cannot read or write memory contents
Reproducible: always

Icom T7H tested first to see if new version of program and USB cable working OK.

Use COM11.
Verified read all memories, save .img file, write all memories to that radio, all OK.

Changed cable to TYT TH-UV3R interface.

Attempt to read existing 44 TYT TH-UV3R radio memory channels.

Program accesses radio, blinks LED red, but resulting file is empty.

Attempt to use Icom image file contents to write to TYT radio.

Program accesses radio, LED blinks green.
Does not program correct contents.

First six TYT memories, previously written, now corrupted.

I realize this was a long time ago. Have you been able to resolve this on your own since you submitted this?
This looks like a cable issue (are you sure you were using the correct COM port?). Please refer to these Wiki articles:
