Can't program a Retevis RT27V MURS handheld

[poltergeisty]

Got a programming cable and installed the universal USB driver. Went to the programming software and nothing. In device manager it says I need a driver. I tried the other USB drivers they have and I can't even install them. Even right clicking the inf file to install I get an error. You'd think the universal USB driver would be what I need.

Things I tried:

Turned the radio on, installed the driver, rebooted the computer. Nothing.

Tried in VMware. Same thing.

Tried on a laptop. Same issue.

It's like I don't have the right USB driver for the cable. Cable says Retevis on it so I'm assuming it's correct. Should be.

Running Windows 7 64. Here's the download link: Resources Center

This main problem is that your radio ONLY operates on MURS channels. It cannot be programed for anything else.

And that IS part of the FCC certification for MURS.

That's not my question at all. I specifically stated I could not get the USB driver to work and as a consequence I can't use their provided software to change tones and an apparent DCS encrypt option I wanted to test to see what that was. You can download the software for this radio right there in the link.


Anyone here use the software for these radios?

You have an FTDI cable/driver incompatibility problem.

Lots of CCRs have this problem.

If your programming cable has a counterfeit Prolific chip and are using the device driver automatically installed by Windows, this device driver is intentionally incompatible with unauthorized copies of the Prolific chip.

For a further info on this problem, go to:

Thanks! That was a huge help. The Prolific driver on that website worked. Yet the version they give on the Retevis website doesn't. Does this mean the cable I bought on eBay is a counterfeit? Here's a picture of the cable.

Also note that these radios default to low power unless you use the programming software and set high power for the full 2 watts. So if anyone buys these there you go.

YES... that cable contains a fake Prolific chip. A lot of people buy FTDI chipped cables now. Me, I fitted out all my cables with cp-2102 chip kits and also eliminated issues.

How did you do that?

How did you do that?

Cut off the chip-end of the cable, soldered on the cp-2102 assembly. The assembly contains the cp-2102 chip and a USB plug

Connecting the radio, turning on the radio and then installing the driver last may be your problem. I have at least 10 different programs for my radios, and they all required installing the driver and then connecting the radio and turning it on. Uninstall everythng for the radio, restart the computer, and reinstall in the correct order and you should be able to make you adjustments.

I tried both methods. Once on my desktop, then in VMware, then on a laptop.
