Programming Cables for Motorola Radios

Motorola Compatible Programming LeadsHere at Radiotronics, we’ve had our own collection of Motorola two way radio USB programming leads made – all compatible with Windows 7 and Windows 10. We’ve put together this handy reference chart which outlines the Motorola part number and our alternative.

Historically, prior to the MOTOTRBO (DP) range, most Motorola programming cables were serial. All of our “compatible” programming cables are USB cables.

We now have a USB multi-cable that is designed to be a replacement for almost all of our previous comaptible cables: Universal Motorola USB Analogue Radio Programming Cable. The cables shown below will be phased out in favour of our Universal Motorola USB Analogue Radio Programming Cable.

Using Licence-free Radios with Licensed Radios

Here’s the thing. You have a number of PMR446 licence-free radios and a number of licensed radios. You want them to work together and your local radio dealer has told you that it’s impossible.

That’s not strictly true. You could program your licensed radios to work on PMR446. But if you do, you risk a £10,000 fine and up to a year in prison. So don’t do that.

The Solution

The good news is there is a viable technical alternative to risking prison time. And it’s by using the SR-628 cross-band repeater control box by Surecom. Introducing the Surecom SR628. See this diagram.

How It Works

You connect Surecom SR628 allows you to connect a radio to either side creating a 2-way duplex repeater. When you talk on the PMR446 radio, this will be rebroadcast on the Licensed radio, and vice-versa. You need to use one of the radios from each system, but this solution allows you to talk between the two sets of radios legally.
