CHIRP

Mark provided the following insight for folks who bought a cable elsewhere and now are having problems getting the radio connected:

The connector for Motorola radio and the Baofeng BF-82WP is what I would call a defacto standard; however, the Baofeng pinout is unique to their radios. For some inexplicable reason, the UV-9R and UV-9RPlus shape of the connector on the radio interferes with the defacto standard cable connector pins touching the radio's connector contacts. The solution is to trim the wedging flange, opposite the screw, by 1 or 2 mm. This "mod" does not appear to adversely affect the BF-82WP.

Based on personal experience, I'd always suggest to buy cables from reputed vendors such as BlueMax49ers in the first place. You will much less likely run into problems, but if there is any, you will also get good customer support.

Except in this case. If you will recall from the original post, Mark is BlueMax49ers.

To solve this issue, I purchased a UV-9R radio and Mark sent me a pair of his BlueMax49ers programming cables. Out-of-the-box, neither the BlueMax49ers or the "official" Baofeng labeled programming cable would work to program the UV-9R. My same type programming cable from Retevis for their RT6, which has a different shell on the connector, worked fine.

After closer inspection, I could see that the way the radio and BlueMax49ers and Baofeng programming cables mated up to the radio, the pins of the programming cable were not properly lined up with the contacts of the radio. Studying which direction the pins were off and by how much, I modified the connector of one BlueMax49ers programming cable with a file until the pins lined up properly. Once this was done, the programming cable worked reliably every time.

In the mean time, I have ordered a Baofeng labeled programming cable which has the same shell as the Retevis programming cable to see if it has the WCH CH340 chip or the Prolific PL2303HXA type chip.

Hmm. Did you contact Mark? I'm certain he would have helped you to resolve the issue. His customer support is very good.
