Allstar® and P25 on Quantar

This is a set of wildcard programing for the Quantar which enables Allstarlink and P25nx linking with mode switching controlled by local traffic. This is possible via some enhanced wildcard programing, and may be applicable for other users using different controllers.

Features

• Support for analog and digital P25 modes with linking

• Asterisk controller has an audio delay of 10ms to 500ms via ARS digital delay board.
  • ID is done by analog controller in this mode
  • PL is output to controller for it to make the decision if it’s needed to repeat.
  • In COS mode P25 will be detected and no repeated.

• PL tail on wire line when on controller (chicken burst)
• When controller unkeys the transmitter stays keyed for 2 second with PL then drops it and stays Keyed for another 5 seconds. This will squelch even the worst baofeng’s receiver.

• Failsoft mode if the controller fails/asterisk dies
  • Turns on in cabinet repeat and ID on that channel in analog mode (digital still works)
  • Requires PL on receive as defined in the channel.
  • Repeater has 4 alarm beeps on it in this mode.
  • Loose the analog repeater delay.

• Mode lock which follows local users keyup after 10 seconds, and locks to that mode (blocks the other) for 5.5 minutes.
  • This currently has a brief clip of audio at 10 seconds as it changes channels.
  • A short call (under 10s) will not cause the system to lock
    • This allows for a short call to not lock the system for the full lockout period.
  • Blocks repeat or wireline of opposite mode.
  • If no received signal of given mode, it goes back to mixed mode.

• Analog mode lock if external input 1 goes low, works on controller and failsoft modes.
  • Blocks P25 repeat
  • Alarm output on station alarm.

• Raspberry Pi controller running both P25nx and Allstarlink DIAL software.
  • This is behind the cisco 1811 router
  • Nat rules allow the asterisk port open to the outside.
