Users can set up built-in encoders and decoders for CTCSS, DCS, DTMF, 2-Tone, and 5-Tone signaling. This allows for selective calling to specific stations or the remote control of repeaters.

The software provides deep configuration for CTCSS/DCS, DTMF, 2-Tone, and 5-Tone signaling. These are not just for filtering noise; they enable selective calling, allowing a dispatcher to ping a specific vehicle or a small subgroup without broadcasting to the entire fleet.

Software is useless without a hardware bridge. The PT8100 uses a standard . However, not all cables are equal.
