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.

Use --dmrconfig-template to specify an exported codeplug config to use as a template for radio type, messages, DMR ID, and startup text. The output directory will contain a dmrconfig config per template specified.

Anytone CPS

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

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

Versions Supported

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
  • To specify a Private call, suffix the talkgroup number with a "P"
• 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

See example: src/dzcb/data/repeaterbook_proximity_zones.csv

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!)

Simplex, GMRS, etc

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

Customization

The channels, zones, and contacts present and the ordering of such in the final generated codeplug is controlled by one or more CSV files passed as parameters.

The column headers correspond to the codeplug objects (zones, contacts, channels, etc) and may appear in any order or be omitted (if no change is requested to that type of codeplug object).

The names used in include, exclude, and order are python regular expressions that match from the beginning of the object name. They are prefix match by default. To opt-out of prefix match, add a $ at the end. All regular expression special characters should be escaped (\).

--include

If the CSV file is passed as a --include parameter, then any objects not explicitly mentioned in the file will be removed.

--exclude

If the CSV file is passed as an --exclude parameter, then any objects mentioned will be removed.

See example: codeplug/default-tyt-md380/exclude.csv (for radios with lower channel/zone capacity)

--order

The remaining objects are sorted alphabetically after processing removals.

Any remaining objects are sorted according to the order specified in the file passed to --order. Similarly, a file may be specified as --reverse-order which will sort in reverse, starting from the end of the list.

See example: codeplug/default/order.csv

--replacements

The replacements CSV column headers are like object_pattern,object_repl and correspond exactly to the arguments passed to python's re.sub. Similar to the ordering csv, object would refer to zones, contacts, channels, etc.

The replacements will be applied to the name of each object of the given type in the listed order. Subsequent patterns will affect previous replacements. Unlike the previous group, these regular expressions are case sensitive, support capturing groups, and indexed replacement.

See example: codeplug/default/replacements.csv

--repeaterbook-name-format

Python format string used to generate channel names from repeaterbook.

The format string will be passed the Repeaterbook API response dictionary for the repeater, so all valid fields are usable in the format string.

The default name format is: "{Callsign} {Nearest City} {Landmark}"

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.
