As you can see from the graphic, the 11800 has a decent db (-40db) which in comparison to 11480 that has about -45db and I'm able to tune that frequency but the 11800 I can't.
sounds like VCM.
Sure is.. actually ACM. It's vertical polarity too unless there is supposed to be one on horizontal as well. I'm up in Canada so the list might look different farther south.:

According to that pdf file, there's two 11800 (Horizontal) frequencies, one for NAFTA and the other one is for South America, so that means why I'm getting high power (about -40db) because I'm getting some signal from both.
Once ago I did a blind scan and as far as I remember was able to get sr = 32727, instead of the sr = 1000 that many guys in this thread were getting, so that means I'm getting more power the South America beam (that I initially tough), but I'm also getting power from the NAFTA frequency, that's why I got lots of noise.
The 6922 doesn't decode ACM or VCM. I also understand that it doesn't do 16 or 32 psk. Need a different TBS card to support these formats.I doubt you're getting the South America beam because it's supposed to end more or less near the Panama/Colombia border according to the coverage maps

so quite far from your location.
Also SatSignature.com shows a wide signal on 11800H (something that looks like it could be a SR of 30000 or more). That is from the US Southwest. So my guess is that it's using some modulation that even the TBS cards can't properly detect
