DMR Zone Channel Builder

dzcb

DMR Zone Channel Builder

• Fetch - fetch input files from local directories or urls
• Assemble - combine information from multiple sources
• Filter - rename, exclude, reorder zones, and talkgroups
• Format - output to common export formats

See Releases for Default Codeplugs

Output Formats

Farnsworth JSON

For import into editcp, with theoretical support for:

• TYT
  • MD-380, MD-390
  • MD-UV380 (tested), MD-UV390
  • MD-2017,
• Alinco DJ-MD40,
• Retevis RT3, RT3-G, RT3S, and RT82 radios

Use --farnsworth-template-json to specify an exported codeplug to use as the template for settings and radio capabilities.

dzcb includes basic template files for MD380/390 and MD-UV380/390.

Anytone CPS

For import into the official Anytone CPS (windows-only).

dzcb generates Channels.CSV, Talkgroups.CSV, ScanList.CSV, and Zone.CSV

Versions Supported

• AT-D578UV CPS 1.11
  • Bridgecom Support
• AT-D868UV CPS 1.39
  • Bridgecom Support
• AT-D878UV CPS 1.21
  • Bridgecom Support

GB3GF OpenGD77 CSV

For import into GB3GF CSV tool. Currently only supporting OpenGD77 target. Tool is "windows-only" but runs decently under wine.

A subdirectory gb3gf_opengd77 is created under the output directory containing the 4 CSV files used by the program:

• Channels.csv
• Contacts.csv
• TG_Lists.csv
• Zones.csv

Note: these files are actually semicolon separated.

Input Format

K7ABD style

A directory of inter-related CSV files describing the common settings needed to program all radios. This is a common format used by K7ABD's original anytone-config-builder and N7EKB's cps-import-builder.

An arbitrary number of files and folders will be combined. At this time duplicate zone names in different files may be problematic. Keep zone names unique. Particularly be wary of trucated names.

• Analog__ZoneName.csv
  • Zone, Channel Name, Bandwidth, Power, RX Freq, TX Freq, CTCSS Decode, CTCSS Encode, TX Prohibit
• Talkgroups__ZoneName.csv
  • No Header Row tuples of: talkgroup_name,talkgroup_number
• Digital-Other__ZoneName.csv -- only really useful for digital simplex channels or private call
  • Zone, Channel Name, Power, RX Freq, TX Freq, Color Code, Talk Group, TimeSlot, Call Type, TX Permit
• Digital-Repeaters__ZoneName.csv -- each line is a digital channel with static talkgroup timeslot assignments
  • Zone Name, Comment, Power, RX Freq, TX Freq, Color Code, talkgroup1, talkgroup2, talkgroup3, ...
  • Typically the Zone Name field is semicolon separated: "Longer Name;LNM"
  • The value for the talkgroup column should be "-", "1", or "2"
  • The talkgroup names must exist in the talkgroups file.
  • Some codeplug targets will create a zone for each frequency with channels for each static talkgroup.

Data Sources

PNWdigital.net

Before using this network, please read the quick start

When building a codeplug with the --pnwdigital switch, data is downloaded from PNWDigital.net/files/acb. The files are updated regularly from the cBridge, so there could be test data or repeaters that are not yet active.

The data is cached by dzcb.pnwdigital

SeattleDMR

Before using these repeaters, please read the website

When building a codeplug with the --seattledmr switch, data is downloaded from seattledmr.org/ConfigBuilder/Digital-Repeaters-Seattle-addon.csv and cleaned up a bit in dzcb.seattledmr

Repeaterbook Proximity

Repeaterbook account is required to access this endpoint

Download live analog repeaterbook data within distance of point of interest.

--repeaterbook-proximity-csv references a csv file with the fields:

• Zone Name,Lat,Lon,Distance,Unit(m),Band(14 - 2m, 4 - 70cm)

This corresponds directly to the repeaterbook csv download "prox" http endpoint, which requires authentication. See dzcb.repeaterbook.

When using this option, be sure to set REPEATERBOOK_USER and REPEATERBOOK_PASSWD in the environment.

Example Format

Longview WA VHF 35mi,46.13819885,-122.93800354,35,m,14,
Longview WA UHF 35mi,46.13819885,-122.93800354,35,m,4,

(it's easy to search on repeaterbook and copy the info from the URL!)

Local

Information on these Western Washington standalone DMR repeaters was retrieved from Repeaterbook and respective websites in 2020 October.

Simplex, GMRS, etc

Some common Digital and Analog simplex frequencies, and GMRS/FRS and MURS channels are included if --default-k7abd is specified.

Bonus: Trim the Contact List

Download the usersDB.bin with Farnsworth editcp.

python -m dzcb.contact_trim \
    < "~/.cache/codeplug/Codeplug Editor/usersDB.bin" \
    > "~/.cache/codeplug/Codeplug Editor/usersDB-trimmed.bin"

Development Usage

Installation

pip install -e ./dzcb

Basic Usage

Download live pnwdigital and seattledmr networks and generate a codeplug in /tmp/my-codeplug with local simplex zones included.

python -m dzcb \
    --pnwdigital \
    --seattledmr \
    --default-k7abd /tmp/my-codeplug

See above and --help for more usage details.
