As promised, I went out in the pleasant 20-degree weather this morning to gather a much anticipated recording of a RSH-10/Thunderbeam.
This particular siren unit is one of many roof-mounted units in the TippCo early warning system. I'd like to point out several things, beginning with the location. It's horrible. I'm not sure what the county was thinking when they installed the unit, but the building it resides upon is level with, if not shorter, than all the buildings around it. I recorded this siren from a parking garage attached to the building, and was about 200 feet away. To make matters worse, this siren seems to be having some major health issues. I am in the process of contacting TEMA about this, however I think that they may already know, seeing as this siren is less than a block away from them. Hopefully it will get fixed or replaced soon.

The siren starts out in alert, but then decides to do its own version of an attack/fast wail signal. Everything about this unit sucks.
