As you adjust this control you will see the red mode width change on the waterfall scale. You can also adjust this value by pointing the mouse to the waterfall. Hold down the Control key and rotate the mouse wheel. The search routine which finds the psk signal operates on a s/n threshold detector as well as recognizing the Psk phase modulation. You can adjust the acquisition signal to ratio threshold for the search routine.<br><br>The PSK decoder estimates the signal to noise ratio, S/N, and the intermodulation distortion, IMD, of the received signal. This measurement is valid during periods when the other station is transmitting the idle signal. The estimates are displayed on the status bar. You can control how these values are displayed; <span style="font-weight: bold;">clear</span> or <span style="font-weight: bold;">dim</span> after NN seconds. Setting the seconds to 0 disables the clear/dim action.<br><br><div style="text-align: center;"><img style="width: 510px; height: 429px;" alt="" src="images/config-pskviewer.png"><br><br></div>Fldigi has a multi channel psk viewer that operates in all of the psk baud rates. You control the look and behavior of the viewer with these settings. The number of channels to be monitored can be set from 5 to 30, spaced by 100 Hz increments. You specify where to start the monitoring with the <span style="font-style: italic;">Start frequency</span> which has a range of 200 to 1000 Hz. Each monitored signal is represented by horizontally scrolling text. Select <span style="font-style: italic;">Continuous scrolling</span> for a marquee format. The text line will extinguish after the <span style="font-style: italic;">Inactivity timeout</span> value in seconds is reached. <br><br>The Psk Viewer operation is described here: <a href="PskViewer.html">Psk Viewer</a><br> <br><h4 style="text-align: center;"><a href="file:///home/dave/dev/dev.FLDIGI/FldigiHelp.working/index.html">Contents</a></h4><br> </div></div></body></html>
