Back to repeater controller main page

The BATC repeater controller uses an onboard DTMF detector which detects DTMF from the mic input on a USB audio dongle (using a standard Portsdown white USB dongle). This can be fed from the main input audion, 144.750 rxr or a separate control rxr.

The DTMF decoder enables off-air control of some repeater functions.

DTMF commands

The command sequence is in the format *xx# but the length of the sequence is variable so a command could be *123456# if required.

Configuration file

The actual DTMF command for each function is entirely flexible and is set in the config file.

It is recommended that some command sequences such as shut down are not publicly available.

See this page for a typical config file listing where the DTMF commands have been grouped as keeper commands - Repeater Controller configuration.

Functions controlled by DTMF

The repeater functions which can be commanded by DTMF are set in the controller software and listed below - these cannot be changed.
