Autochart shows very low freq sonar in recording
I have a Solix 12 Mega. I recorded a trip a week ago, and was reviewing on AutoChart on PC. I can choose any of five sources. Two side-scan, one 'mega/high' down scan, one 'med/high' down scan, and something that has a very wide coverage range. This last one shows triple the arches that the the med/high down scan shows - but I cannot show this when replaying the recording on the Solix. I can't find this freq when I create a new view (3 panes: side scan, mega down, and med/hi down).I just realized that I didn't try a single view panel, maybe I can show this low freq there...?In the settings, chirp section, there's a band for 50-100 khz, 2d, and mega. I'm sure I'm seeing the 50 khz range in AutoChart. So I need to figure out why I can't access it in a view.I am on the latest firmware, as of July-ish, 2023.Thanks, guys!

I figured it out.83 khz is one recorded channel. Then 200, then DI, then SI has two.I had to turn contrast down to 1, and sensitivity down to single digits, to see the very weak arches far from the center of the beam, during head unit replay. I had been running sens at 20, and contrast medium high, which only showed the strongest echoes in 2D.

B000- 83 KHz, B001 200 KHz, B002-003- SI, B004 DI. Major channel is B001, it's future map source.
