In fact the SDRPlay website has a search tool that you can use for finding both YouTube videos and, sometimes, PDF documents that will give you a lot of help with SDRPlay devices. https://www.sdrplay.com/apps-catalogue/ Be sure to click the 'Include third part content' and 'Search all Categories' boxes.
SDRPlay even has its own reflector on groups.io here....https://groups.io/g/SDRPlayUsers
Something specific to ACARS- there is a short beep that precedes each transmission. If the software doesn't hear the beep, no decoding will likely occur. Leave your squelch wide open - most consumer radios simply don't open up fast enough. Now how about what modes are readable? It's easy to get overwhelmed when there are so many modes from which to choose. When we get to HF (and LW) there are tons of modes that are simply unreadable. However there are 2 generalities you can make;
a. Amateur radio data modes are ALWAYS readable. MultiPSK doesn't - and likely couldn't - cover them all. What frequencies and modes are used are, to a certain extent, regulated by whatever national law (for example, US and UK hams are allowed operations on the 5 Mhz band - many other countries don't have that allocation). There are tons of modes hams can use, and there are some places where you can look up specific bandplans...
b. When we get outside the ham bands, things get a little murky. There are lots of unreadable modes but but there are those that can be read with the right sofrware. These are outlined here...https://wiki.radioreference.com/index.php/Testing_Your_New_Setup
