Good Evening everyone,
As some of you might know; Battle Creek Michigan performs siren tests on the First Saturday of the month at 1pm. Since most of these sirens don't have the newer Federal Signal radios, they are can not transmit test results back to central dispatch since those radios are can only receive. They ensure all sirens work, a big group of volunteers so each siren and report the test results over their radios. That means for us enthusiasts is that we can tune into that frequency they use to communicate to see what sirens have been working. FAN DUDE has been going to battle creek pretty much every month and we have started a spreadsheet of test results based on what the volunteers said.
HERE is the link to the spreadsheet. This month (Nov 2020) was a big surprise to us. Only three sirens in the whole system went off. Interesting.
