Today was a full test day for Rochester, so off I went this morning to record a siren there. Rather than go to another 2001, I decided to give a Modulator a try, just to shake things up a bit. I believe there are four in the city, three 3012s and one 6024 (this one). This was the second of the four installed, and was put in to cover a large nature reserve to the east of downtown. As far as I know, there was nothing here prior to the Modulator. The city EOC was late with testing as usual, and did not start toning the quadrants out until I had emailed them. The test started out with a pre-test announcement on all of the electronic sirens, followed by the full alert. You might be able to hear faint sirens from other zones before this one starts the cycle. My Vixia really did not like the sound of the Modulator (which I have had problems with in the past), so I apologize for the harshness of the sound. There is nothing I can do about it. When the Modulator turns off and finishes the post-test announcements, you can hear the sirens in the neighboring zone to the south keep going for awhile before turning off. If you listen carefully, you can even hear the nearby Modulator doing the post-test announcement. Thank you for watching, and enjoy!
Sirens in the City of Rochester are tested on the first and third Wednesday of every month at 10AM April-September, weather permitting. From October-March, they are tested on only the first Wednesday for a shortened 1 minute test.
