7.4. RX Subaudio

The RX Subaudio tab defines the CTCSS or DCS tone for the current profile.

7.5. TX Subaudio

The TX Subaudio tab defines the following fields:

• CTCSS Deviation

• DCS Deviation

7.6. RX Mute/RSSI

The Mute/RSSI Tab stores the mute settings for the receiver. The mute state can be

determined either by the signal strength in dBm or the carrier to noise ratio in dB. Typically,

the RSSI Hysteresis will be set in the range 2-4dB, and both C/N and C/N Hysteresis will be

set to zero.

7.7. RX P25

Conventional APCO P25 systems use a Network Access Code (NAC).

The Rx profile (P25 Tab) allows user to specify whether the base station shall accept a P25

call with any NAC or with a user specified NAC, thus restricting radio network access.

Three specific NAC codes are set aside for the following functions:

• 293 – Default NAC

• F7E – The receiver will unmute on any NAC

• F7F – This will cause the transmitter to set its NAC from the received NAC.

7.8. TX P25

The TX C4FM modem can be configured to transmit a STD DEV or STD 1011 patterns for

servicing and testing purposes.

Deviation scale allows user to adjust the deviation in a range from 90% to 110% from the

normal setting of 100%.
