Waterfall Issue


George Stein - NJ3H
 

Greetings,

Hopefully someone can offer some help to me on the issue I will describe.  Please see the attached picture.

I am using FLDigi (two instances) to copy two tty feeds from rtty.com.

The top decode's waterfall is a normal width, while the bottom decode's waterfall is stretched almost the entire window width.  I am using separate Virtual Audio Cables to connect each stream with FLDigi.

This is something new and I cannot figure out why this is happening. Any ideas from those reading this message?

Thanks and regards,

George,

My first guess is that the volume into fldigi in the one with the full waterfall is higher than the other one. To verify that click the WF buttom, bottom - left below the waterfall. the FFT trace in the one with the full waterfall will be higher up the scale. Check the Windows mixer to adjust the volume. It doesn't hurt anything, but I suspect that is why the difference.

It could also just be that the full waterfall image is a stronger signal. That also would show a higher FFT trace.
