And, for you brave Radioddity GD-77 fans, Jason has a page of GD-77 mods for you to view. You’ll need to update the callsign and User ID with your information before downloading it to your radio.

Remember that codeplugs from someone else are an excellent place to start. To download this file, you may need to right-click on the link and select “Save Link/Target As.” You’ll need to rename this file to SCARSGD-77311.dat. You can either copy your codeplug to the radio after the upgrade or grab our W5NOR Oklahoma Codeplug for the GD-77 Version 3.1.1 and after. You can download the new firmware using the program update.exe.

Power on the radio while holding the bottom two buttons on the radio’s left side to put the radio in firmware download mode. Version 4.3.6 is available to download from the Radioddity website. Radioddity has a new version of software and firmware for its GD-77. These radios will receive either analog FM or DMR signals. However, there are a couple of repeaters on the VHF band. Here is the most recent Tytera v1.37 software used to program the MD-390 and MD-380 radios. This software is free and available from Jerry and the people at Connect Systems. That page lists the radios supported with the current build. It supports many manufacturers and models and provides a way to interface with multiple data sources and formats. This software is a free and open-source tool for programming your amateur radio. Listed below are these programs, with links to that software. Each codeplug title starts with the name of the program that is used to download that plug.

Software programs are used to program these radios.

These are all provided ‘as is,’ and use them at your own risk. These codeplugs are for the Norman, OK area. This page is a repository for codeplugs that you can use with amateur radios.
