tfurrows and solderpunk recently phlogged about the storm system that
passed through the USA and caused a bunch of tornadoes. The worst of
that thankfully messed our little town, but things were still dicey
even just a little bit outside of town and in nearby smaller towns,
townships/counties/villages/etc... That day I happened to have my new
p25 radio setup going, slurping in all of the radio traffic from all
of the talkgroups on multiple trunked radio systems in parallel, and
that radio traffic actually turned out a lot more interesting than it
usually is.
There is a lot of preparedness and people getting busy as these types
of storms come in happening that most people don't know about. All of
the counties surrounding a particular NWS office have their own 'EOC'
(Emergency Operations Center) - All of the spotters report to their
EOC's and the EOC's in turn report back to the local NWS office over
the radio. I managed to capture all of this traffic, which was neat.
Not so neat are some of the reports you start hearing pretty soon in,
first about hail, damage, but soon forming funnel clouds and actual
tornadoes touching down left and right, which I must admit was a bit
unnerving to listen to as the storm got closer.
At one point, a tornado formed near the town just north of ours and
for a moment things were looking like the town was about to get hit,
but thankfully instead it went just north of the town; but not before
first crossing the interstate, and knocking over a tour bus and a few
semi's, and a bunch of powerlines. You could hear the frustration of
emergency responders as they could not get near the bus due to downed
powerlines on the interstate.
Anyway, I zipped up all of the audio of that day and uploaded it here
so you can listen to it too!

The filenames start with the talkgroup id followed by the timestamp
of the recording. For example:
9021-1680324909_855162500-call_4036.m4a
would be tgid: 9021 and timestamp: 1680324909
Standard unix timestamp, you should be able to convert it to human-
readable text with the date command, eg:
> date -d @1680324909
Fri Mar 31 11:55:09 PM CDT 2023
(note the @ prefix)
Anyway, the talk group for the local NWS (in Lincoln IL) is 30324, so
if you just want to listen to only those, assuming mpv as your audio
player, you could just do:
mpv 30324-*
If you want to get a more complete picture and listen to >EVERYTHING<
in order, then you will have to strip the talkgroup id prefixes off
of the filenames first and then just run `mpv *.m4a` - I kept all the
chatter in of various police departments, local gas company, EMS, DOT
and so on, so you can get a complete idea of the storm impact, but
obviously there's also going to be a lot of non-storm irrelevant chat
going on if you listen this way, although it'd give a more realistic
overview.
Anyway, it kind of sounds like that the way things are looking, we're
about to get more similar weather here soonish.
