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

The walkthrough uses mycodeplug/example-codeplug [input files]

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

(links fetched 2021/01/24)

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

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

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

  • Zone Name,Lat,Long,Distance,Unit,Band(2m;1.25m;70cm),Use,Operational Status,etc

The fields after Band are optional and correspond directly to the field names and values in the Repeaterbook API (see examples).

--repeaterbook-state is a space-separated list of US states or Canadian provinces that should be included in the proximity search. Including more states will increase the time required to generate the codeplug.

Repeaterbook API data is downloaded and cached in a user and platform-specific cache directory. Data will be refreshed if it is older than 12 hours. When downloading from Repeaterbook, a delay of 30 seconds is introduced between requests to reduce load on the repeaterbook servers.

Please respect their servers and submit changes requests to repeaterbook directly.

See dzcb.repeaterbook.

Example Format

Zone Name,Lat,Long,Distance,Unit,Band(2m;1.25m;70cm),Use,Operational Status
Longview WA 35mi,46.13819885,-122.93800354,35,miles,2m;70cm,OPEN,On-air
Longview WA VHF 35mi,46.13819885,-122.93800354,35,miles,2m,open,On-air
Longview WA UHF 35mi,46.13819885,-122.93800354,35,miles,70cm,OPEN,On-Air

(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.
