Programming the channels in the GD-
In fact getting the Code Plug the way I wanted it took me about two weeks, one week to work out how to get it to the point where I could actually use the radio, and the second week to add and adjust all kinds of things to make it easier to use.
Of course this is an ongoing process, I am still finding things which need to be adjusted or tweaked by watching YouTube videos and reading pages online about DMR.
Below are a couple of images of digital and analogue channels being edited.
As can be seen from the images different options are greyed out depending whether an analogue or digital channel is being edited although there are obviously some things you need to enter which are the same on both screens such as the name of the Channel, Tx and Rx frequencies, Power levels, Tx Time Out and Rekey Delay.
Note: If you set a TOT time the Rekey Delay is set to 255s by default so make sure you you change the Rekey Delay to a sensible time after setting the TOT otherwise you will be waiting a very long time before you can transmit again after a Time Out.
On both types of channel you will also find the Scan List selection box below the Admit Criteria selection top right where you can select the previously created Scan List to match the Zone the channel will be in.
To be considerate to other users it’s best to set the Admit Criteria to ‘Channel Free’ (or ‘Colour’ on digital channels) on repeater channels.
On the digital channels you have to correctly select the Rx Group List, Colour Code, default Contact (TG) and the Repeater Slot in the lower right side of the window.
On analogue channels you just need to set the Bandwidth to 12.5kHz on VHF or 25kHz on UHF and the CTCSS tone frequencies for repeaters.
