What You Need To Program GP340/GP344/GM340 Series Radios

Programming the Motorola GP340 (or GP300 Professional) series radios is relatively straighforward. But there are some things you will need to do so.

1. GP300 Professional Series Programming Software

The Motorola GP300 Professional Series Programming Software can be found on your website here. It's a simple instant download (if you pay by credit card or Paypal) and you can install it straight away.

2. Programming Lead Kit

Here's where it gets a little more complicated. The GGP300 Professional Series were first created when computers still typically had RS232 serial ports. These days however, most computers only have USB ports. The Motorola RIB box, the box that sits between the computer and the radio, is still RS232, not serial. The table below gives a quick and easy reference for which cables work for which radio.


The RIB (radio interface) box is a box that stis in between the computer's serial RS232 port and the radio. Whilst we now offer some RIB-less cables, most cables do not work without a RIB box. This is because in the very old days, a 9V supply of power needed to be injected into the serial connection. Therefore all GP300 series professional series cables require a RIB box.

How to Download After Purchase

After you purchase and have completed checkout you can download this software from Your Downloadable Products area of our website.

Two Way Radio Programming Service

Radiotronics offers two way programming at our service centre. If you would prefer, we can program your radio for you. Programming fees start at £6 (+VAT) per radio with a minimum charge of £20 (+VAT) excluding postage. If you'd like to enquire about programming, please email us on sales@radiotronics.co.uk. Please do not contact us about support for self-programming radios or programming software - see below.

Software Support Unavailable

Unfortunately, we cannot offer technical support for self-programming two way radios. If you choose to program your own radio, we urge that you allow plenty of time to self-learn about your radio and the programming process - it's not always straightforward. We offer a programming service at our service centre - see above.

Obsolete Operating Systems Tip

Some programming software may require an obsolete operating system such as M.S. DOS, Windows 3.1x, Windows 95/98, or Windows XP for example. You can usually run obsolete operating systems inside virtualisation software such as VirtualBox virtualisation software. The obsolete operating systems can usually be legally obtained from WinWorld.

Software Ownership & Download Disclaimer

For convenience, we offer software for download instead of physical CD delivery. Software provided by Radiotronics is supplied free of charge. Any fee you pay to us in the process of obtaining software should be regarded as a "download and administration fee", which simply covers the cost of data file storage and the bandwidth used when downloading the software. The "download and administration fee" can range from £20+VAT to £99+VAT and is directly proportional to the size of the files and the quantity of files available for download. Any software Radiotronics provides will remain the property of the manufacturer and, whilst you are free to use it to configure your radio or device, you will NOT own the software.
