pyrepeater

a software controller for radio repeaters on raspberry pi

tested with:

• Raspberry GNU/Linux 11 (bullseye)
• serial interface board from www.gmrstwowayradio.com
• FTDI USB -> Serial cable
• Retevis 97S

installation

1. clone the repository
2. install Python 3.11
3. install pipenv
4. cd to pyrepeater/pyrepeater/
5. run pipenv install

configuration

1. replace the files in the "sounds" directory with wav files crafted for your repeater.
2. copy pyrepeater/.env.example to pyrepeater/.env and edit the settings to reflect your preferences. (see settings below)

usage

1. cd to pyrepeater/pyrepeater
2. run pipenv shell
3. run python __init__.py

settings

the following ENV variables should be set in the .env file prior to entering the pipenv virtual environment

• SERIAL_PORT=/dev/ttyUSB0

  • the location of your serial device

• PRE_TX_DELAY=1.0

  • the number of seconds (float) to wait between enabling the serial pins and beginning the transmission audio

• POST_TX_DELAY=1.0

  • the number of seconds (float) to wait between ending the transmission and disabling the serial pins

• FCC_ID=WRXC682

  • currently unused. (future: cw id generation)

• SCHEDULE_TOH=False

  • currently unused. (future: timed periods relative to top of hour or start time)

• ID_MINS=15

  • period of CW ID annoucements in minutes (int)

• RPT_INFO_MINS=60

  • period of repeater info annoucements in minutes (int)

• ID_WHEN_ASLEEP=False

  • send CW IDs when repeater is idle for a prolonged period

• RPT_INFO_WHEN_ASLEEP=False

  • send repeater info messages when repeater is idle for a prolonged period

• SLEEP_AFTER_MINS=10

  • after this many minutes of inactivity, put the repeater in sleep mode

• WAKE_AFTER_SEC=2

  • if repeater is asleep and becomes busy, wait this many seconds (int) before transitioning back to active state (prevents short key ups from disrupting sleep)

• MIN_REC_SEC=2

  • minimum seconds for a valid recording (wav file will be deleted if it does not exceed this length)

roadmap

• repeater modes (day/night/net)
• ansible
  • systemd service
  • blacklist headphone jack modules
• single command install (ie. homebrew/ohmyzsh curl .....)
