I use that Crime Radar app as well and have noticed that incorrect label, too. I sent them some feedback along with a screenshot showing the incorrect name, so hopefully it will get fixed.
Edit: I suspect the incorrect label is due to their AI transcription service. It's somewhat accurate but does tend to garble things like street names and place names. They probably didn't realize that Marshall EMS is in an entirely different part of the state.
Also, I'm the one providing the feed to Broadcastify Calls. It's still kind of a work in progress so I haven't posted anything publicly about it yet. Right now it's just audio from FD dispatch channels, BC Fire (fireground) and Medstar EMS. It's also only pulling audio from the Magnolia Springs site, since that's the one with the best signal where I live. Some call activity is sporadic, like Orange Beach FD and 911 North. Sometimes they're on Magnolia Springs, sometimes they aren't, so some calls are getting missed.
I'd eventually like to add Robertsdale and maybe even Seminole AIRS sites but right now both are giving me reception issues so I've held off on adding those. Gulf Shores, Fort Morgan and Orange Beach sites are all way too weak to decode for me so they're not options. A lot of Gulf Shores and Orange Beach city traffic (lifeguards, beach conservation, etc) don't make it to Magnolia Springs or Robertsdale sites.
