Looks like you have a very narrow filter width defined in the radio? Can you open that up?

Alright, making progress left and right today.
Turns out my input audio levels are too low. I get to decode some signals, but not all of what is out there. I'm currently getting about 2 or 3 signals per cycle.
I followed the steps in Brian's video (https://www.youtube.com/watch?v=RxWiDYMcRn4) where he uses alsamixer to set levels. LO is at -6.0 and PCM is at -11 and that is where my ALC starts to move.
The signals coming in are not great and my waterfall looks like its been truncated:
I called Yaesu tech support and they actually didn't have a reference for this input (-1 for Yaesu!). But they told me no more than .5 volt and the recommended setting is 100mV
Using Brian's spreadsheet I get
for .5 volts I get -3
for .1 volts I get -17
Neither of them improve the results or the waterfall.
For reference when I have the rig set to "USB" this is what the waterfall looks like and I get lots of signals in:
