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

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 and crappy!!!
# Fetch an appropriate tarball from https://go.dev/dl/
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
Arch-based distros (Arch Linux, 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
macOS, on x86 and ARM:
brew install go git 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/.

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.
