There is no LRPT decoder flowgraph in satnogs by default. There is a thread… somewhere on here about adding a custom one to decode it. Your station is probably using the default FM flowgraph, which results in a waterfall with a narrower bandwidth (48 kHz) than the LRPT signal (~80 kHz).
However, I’m not sure if Meteor M-2 is functional at the moment? I know there was some issue with loss of attitude control a few weeks ago, unsure if it’s been resolved.
As for signal, from the bit that I can see on that waterfall, you are receiving it, but there is a lot of fading, which could be the attitude control issue.
