Amateur Radio Station Remote Closedown Controller

Simple tool used to kill transmission from a remote amateur radio station, gateway or repeater.

Or a very over-engineered means of complying with licence terms for remote stations, gateways and repeaters.

Features

• Allows controlling the following via MQTT:
  • TX/radio/PA power
  • PTT/transmit enable
• Provides feedback of the following via MQTT:
  • TX/radio/PA power state
  • Transmit state
• Can automatically (attempt to) disable transmission if the radio has been transmitting for too long (e.g. PTT becoming latched for whatever reason)

Configuration

See the example.

tx_guard_time is specified in milliseconds. IO pin numbers are expected as per their appearance in sysfs (for the Raspberry Pi, this means the "Broadcom"/"chip" numbering).

Usage

See remote-closedown --help.
