General Description

 

CTCSS application opens the noise squelch when some of the CTCSS tones is detected and the tone power exceeds the given threshold value. When the CTCSS tone power is again below the threshold the squelch is then closed.

 

CTCSS tones are (Hz):

67.0, 71.9, 74.4, 77.0, 79.7, 82.5, 85.4, 88.5, 91.5, 94.8, 97.4, 100.0, 103.5, 107.2, 110.9, 114.8, 118.8, 123.0, 127.3, 131.8, 136.5, 141.3, 146.2, 151.4, 156.7, 162.2, 167.9, 173.8, 179.9, 186.2, 192.8, 203.5, 210.7, 218.1, 225.7, 233.6, 241.8, 250.3

 

 

 

 

Parameters

 

Enabled

This enables the CTCSS functionality. If not enabled, signal is just passed through.

Enable Filter

If activated the filter removes all the CTCSS tones from the audio signal.

Threshold

When the CTCSS tone power exceeds this value the noise squelch will be opened

Power

This is the display of current CTCSS tone power.

All Tones

If this is selected the squelch, will be opened if ANY of the CTCSS tones is detected.

Tone

When this is set. The squelch will be opened only when this tone is detected.

Detected Tone

This dialog shows the frequency of the most recently detected CTCSS tone.

Log File

The detected tones can be saved to the log file.
