This information is intended purely for educational purposes. It is your responsibility to ensure that you and your equipment are behaving themselves properly.

Requirements

You must have the following tools installed:

  • (REQUIRED) Python 3.10.x or newer; for using the "multi_outputter.py" script for processing the input data files
  • (REQUIRED) gojq; for working with JSON payloads
  • (REQUIRED) dmrRadio binary 1.0.23 or newer; for exporting/importing codeplugs to/from JSON and generating blank codeplugs
  • (SUGGESTED) editcp 1.0.23 or newer; for further editing codeplugs
  • (SUGGESTED) LibreOffice; for creating PDF handouts to accompany the programmed data

There are some really good programming tutorials at https://youtu.be/VExx628R0DM and https://youtu.be/Lw0Y-jQZMZ0 which are useful for learning about the digital side of things.

Running Things

# Initial setup
make && source .venv/bin/activate

# Create and upload new codeplugs
./scripts/generate_rdt.sh     # create generic codeplugs for anybody
./scripts/personalize_rdt.sh  # create specific codeplugs for my radios
dmrRadio writeCodeplug tmp/foo.rdt          # upload a single codeplug

# Fetch and upload new contacts
./scripts/fetch_db.sh         # download a bunch of fresh contacts
dmrRadio writeMD2017Users tmp/filtered.csv  # if radio is Retevis RT90
dmrRadio writeUV380Users tmp/filtered.csv   # if radio is Retevis RT3S

# Produce data in a format useful for analog radios
./scripts/generate_csv.sh  # create programming data for analog radios

Radio Programming Kiosks

Arch-based distros (Arch Linux, EndeavourOS, etc.), on x86 and ARM:

sudo pacman --no-confirm --sync gcc git go libusb pkgconf
git clone https://github.com/dalefarnsworth-dmr/dmrRadio && cd dmrRadio
go build

Debian-based distros (Debian, Ubuntu, Raspberry Pi OS, etc.), on x86 and ARM:

# Don't use the go provided by the OS as it is super old
# Fetch an appropriate tarball from https://go.dev/dl/
# Install the contents of the tarball somewhere convenient
sudo tar -C /usr/local -xvfz ${GO_TARBALL}

sudo apt-get --yes install git libusb-1.0-0-dev
git clone https://github.com/dalefarnsworth-dmr/dmrRadio && cd dmrRadio
go build

macOS, on x86 and ARM:

brew install git go libusb
git clone https://github.com/dalefarnsworth-dmr/dmrRadio && cd dmrRadio
go build

Windows users should probably just go fetch the pre-built (x86) binaries directly from https://www.farnsworth.org/dale/codeplug/dmrRadio/downloads/windows/ and https://www.farnsworth.org/dale/codeplug/editcp/downloads/windows/.

Converting Existing Codeplugs To Templates

# Export the binary codeplug as JSON and fix some values
dmrRadio codeplugToJSON codeplug.rdt before.json
gojq --from-file Retevis_RT3S.jq before.json > after.json

Generating Codeplugs From Templates

# ========
# WARNING:  Don't put spaces in the intro screen lines
# ========

# Create a data file containing your specific values
cat << EOF > VA3DGN.conf
{
  "GeneralSettings": {
    "IntroScreenLine1": "VA3DGN",
    "IntroScreenLine2": "3023396",
    "RadioID": "3023396",
    "RadioID1": "3021794",
    "RadioID2": "3023706",
    "RadioID3": "3021795",
    "RadioName": "VA3DGN"
  }
}
EOF

Starting a New Codeplug

# Create a brand new, empty codeplug
dmrRadio newCodeplug -model RT3S -freq "400-480_136-174" new.rdt

# Make it even emptier still
dmrRadio codeplugToJSON new.rdt new.json
cat new.json \
    | gojq 'del(.Contacts[])' \
    | gojq 'del(.Channels[])' \
    | gojq 'del(.GroupLists[])' \
    | gojq 'del(.ScanLists[])' \
    | gojq 'del(.Zones[])' > empty.json

DFU Mode

Retevis RT90 DFU mode uses orange emergency button + P1 + plug-in "hard" power (ignore "soft" power button).

Retevis RT3S DFU mode uses top side key + PTT + twist power knob.

Admit Criteria determines when your radio is allowed to transmit. The recommended setting for repeater channels is Color Code Free; this configures your radio to be polite to your own digital system. You should configure your In Call Criteria to Follow Admit Criteria. Simplex channels should be configured as Always for both Admit Criteria and Always or Follow TX for In Call Criteria.
