John, GM1YME, has produced a codeplug which he has made available as stated in the message he sent me below: – Feel free to share my GD-77 codeplug which has all UK Analogue and DMR repeaters in it plus other useful frequencies. It’s optimised for Scotland but can easily be changed. http://www.gm1yme.uk
James, G7MLO, has kindly made available a codeplug for the Radioddity GD-77 dual band DMR radio. It is customised for the East Anglia region. You must use CPS version 2.05 and radio software version 3.00.06. Both are available to download from the Radioddity website. You can download a copy from HERE.
