DSDPlus Why is one of my FMP24 windows painting a red waveform line?

[rolypolyman]

One of my FMP24 windows is painting the wideband waveform line in a red color. This just started today. Any idea if this is indicating an error?

Shown here are my two SDR radios... the top one is the one painting the red (or pink) color. The bottom one is the other radio, showing the standard white color for the same line.

Check the console window.

Your first display is normal and shows a lock on 462.05000. white showing the control channel, green showing the control channel in the IF. The grey bar is the 6.5 Mhz decoding bandpass.
Your second display shows the tuning at 157.30000 and there is no signal there.
A change in your .bat files can do that where -f157.30000 has been entered and no control channel there.
If you click in this active window, this can also 'slide' your frequency off. you can continue to click and search for the white CC spikes, then clicking on one will center that in the decode IF.
You can go up or down in frequency.
I do this changing sites and don't have to restart FMP. This also starts new logging.
Looks like you are 1.4 Mhz high here, click on the left side of the panel until you see your 155.865 CC then click on it to center.
Check your frequencies in you .bat files and frequencies list also.

The 157.300 red line is just the cursor following the mouse around and it remains at that location when the FMP24 window is no longer in focus. Nothing has been tuned at 157.300. Also there is no control channel, 155.865 is acting normally and logging transmissions fine; it's a non-trunked P25 system.

@rolypolyman: If I understand your question correctly, you are asking why the spectrum display is drawn with a pinkish tint instead of white. Slicerwizard very subtly pointed out that it does this when it enables the "extra CPU loading" mode (see the release notes in Notes.txt).
