I’ll be dropping support for the original GD-77 Firmware and instead will target my codeplugs for use with the most excellent OpenGD-77 Software, developed by Roger Clark – See

For direct downloads, please head over to which is the Tier2 branch with daily firmware builds.

Although in alpha stage, it works like a charm. One flashes his GD-77 with the GD-77 firmware update tool from the original firmware package. Once you install Roger’s “Community CPS” – you get access to an extra menu for the OpenGD-77.

I’ve made a Belgian Codeplug for the OpenGD-77. You can download the codeplug here. (Version 1.1 – 31 oct 2019)

OpenGD-77 Community Tools

There’s two tools that need a place here – they’re the Community CPS created by Roger Clark and the Contact Manager by Colin Durbridge.

Note that for the OpenGD-77 you’ll want to install the COM port driver as well before use. It should be included in the CPS – but if you have issues, you can find the COM driver here.

Note: The section below will not be maintained anymore.
Please support the OpenGD-77 project as much as possible.

Belgian Codeplug

To facilitate use in Belgium – here’s a generic codeplug for firmware 3.1.1 and up (3.2.2 at the moment). I prefer the Community CPS – see below (Version: 5.7 Date: 20190630 – Full BeNeLux Support Changelog). Don’t forget to change your DMR ID under “General Settings – Radio ID”.

BeNeLux DMR ID Database

The following link generates BeNeLuxFr DMR ID lists for the Radioddity GD-77 on-the-fly. It uses data from Ham-Digital (GDPR Proof). Data is cached 2 hours max, as not to put load on the Ham-Digital servers. Needless to say: it’s always up-to-date.

To read or write DMR ID data on the GD-77: Press ” SK2 + Menu (green button) + # “-keys at the same time while turning on the radio. The unit will seem to start normally, but it will accept the connection for the DB upload. Then use the tool supplied with firmware 3.1.1 and up. (Only start the tool AFTER powering on the radio – name of the tool is ActiveClient.exe).

Belgian Online Repeater List

For those wanting to create their own codeplug – the following link serves you a CSV-file with all active Belgian repeaters that have been online in the last 48 hours. Handy to check for new repeaters, or clean up older codeplugs. The list contains location, callsign and input / output frequencies.
