Introduction
============

This is my fourth version of a codeplug for DMRplus and BrandMeister, the second
optimised version for OpenGD77. It is completely revised and extended with over 100 "new"
repeater channels. 4v0a is a fixed version of 4v0 where a problem with "phantom" zones
(residual activated but empty zones from the stock CPS) exists (thanks to Colin G4EML
for investigating and fixing).

The source for the repeater data was:

http://spacesupport.de/repeater-liste.php
https://www.spacesupport.de/digitalfunk/dmr-dmr/deutsche-brandmeister-repeater/deutsche-bm-repeater-small-page/
https://ham-digital.org/dmr-rptrreg.php#DEU
https://repeatermap.de/

It took me several weeks to go through the data, merge it, (cross)check it an
hack all the stuff into the CPS and go through every channel and configure it.
And you can be almost sure, that the DMR landscape changed while you're uploading
the codeplug to your radio :-)

Feel free to use my codeplug and change it for your needs. I would appreciate to get
feedback or maybe improved versions of the codeplug.

Don't forget to change the "Radio ID" to your personal DMR ID.

Because OpenGD77 supports several radios with the same codeplug format, I will stop working on
the codeplug for the original Radioddity CPS for the RD-5R. The workflow to maintain this
codeplug is complicated and extensive.
In theory a codeplug can be build from the OpenGD77 codeplug using the tools described below
at "The CSV files".

Codeplug_OpenGD77_by_DL9SEC_4v0a.g77
===================================

"Codeplug_OpenGD77_by_DL9SEC_4v0a.g77" is a codeplug for OpenGD77 covering Germany from north
to south, from east to west. It should work on all OpenGD77 supported devices (GD-77 -> tested,
GD-77S, RD-5R -> tested and DM-1801).
The codeplug contains BrandMeister and DMRplus repeaters known in January 2021, as well as
VHF/UHF repeater channels, PMR channels (RX only), Freenet channels (RX only), home repeater
and FM/DMR call frequencies.

The VHF repeater channels are named <channel number>:<RX freq - 140MHz>. TX offset is -0,6 MHz.
The UHF repeater channels are named <channel number>:<RX freq - 430MHz>. TX offset is -7,6 MHz.

Naming convention for BrandMeister repeaters:

   <call>-BM for UHF and <call>-VBM for VHF
   <call>-<repeater number>BM for repeaters with more than one channel
   <call>-BMS for UHF simplex repeaters and <call>-VBMS for VHF simplex repeaters
   
Naming convention for DMRplus repeaters:
  
   <call>-D+ for UHF and <call>-VD+ for VHF
   <call>-<repeater number>D+ for repeaters with more than one channel
   <call>-D+S for UHF simplex repeaters and <call>-VD+S for VHF simplex repeaters
   
The timeslot of a channel can be changed by pressing * on the keypad.

The zones are created using a north part and south part after regions or administrative districts.

Additionally there are two channels prepared for a local BrandMeister hotspot:

A channel for a UHF duplex hotspot:
 
   HOTSPOT-BM
   
A channel for a UHF simplex hotspot;
   
   HOTSPOT-BMS
   
The output power is limited to 50mW for these channels.


The CSV files
=============

There are four CSV files existing:

   Channels.csv
   Contacts.csv
   TG_Lists.csv
   Zones.csv
   
These files are exported from the g77-codeplug with Colin G4EML's great codeplug utility
'OpenGD77-CSV.exe' and can be modified very easy with e.g. LibreOffice and converted back
to a g77-codeplug.
The tool can be found at http://www.gb3gf.co.uk/downloads.html where you will find further
tools to convert codeplugs exports maybe to other formats on the base of the CSV files.
