Counterfeit Prolific programming cables and the Baofeng UV-B5 and UV-B6

Miklor has an excellent tutorial which explains the situation with counterfeit Prolific cables, and how to get the correct driver installed and working.

In short, it’s simply a matter of installing the correct cable driver (the older Prolific driver), plugging in the cable, and then choosing the correct driver in Device Manager. In Linux, the cables seem to work fine with no issues.

There are a couple of additional things to keep in mind:

1) After installing the working driver, make sure you continue to plug the cable into that same USB port. Plugging it in to a different port will cause the Windows driver to reload. If you do, just update it with the working driver again.

2) Windows Update may offer an update to your “outdated” Prolific driver. Just block or hide this update.

3) If you plug the Prolific cable into your radio with the wrong driver installed, the LED will turn red. You ARE transmitting a carrier. Keep that in mind. Make sure your radio is tuned to an in-band, unused frequency before plugging the cable into your radio if you’re not sure of the driver situation, or just check Device Manager, as the wrong driver will show a yellow exclamation mark.

Here’s a photo of the led gone red from the wrong drivers installed:

Baofeng UV-B6 frequency issues above 499Mhz

The Baofeng UV-B6 (and B5 too, I’m assuming) are factory programmed to operate UHF up to 480Mhz. You can easily unlock this to 520Mhz through either the Baofeng software or CHIRP.

However, the radio exhibits some really strange display issues when you tune above 499Mhz. Take a look at the two videos below for a demonstration.

It’s also worth noting that the UV-B6 antenna that mine came with was only indicated for use up to 480Mhz. Yours may be the same.
