Name of specific trunked radio system for the talkgroup may be entered across fields normally used for
channel information.

RX Tone/NAC- CTCSS tone or Network Access Code for the received frequency.

TX Freq, N or W- Transmit frequency as the mobile or portable unit would be programmed for using nnn.nnnn followed by a
“N” for narrowband or “W” for wideband.

TX Tone/NAC- CTCSS tone or Network Access Code for the transmitted frequency.

Mode- “A” for analog, “D” for digital, or “M” for mixed mode operations.
