I remember as a kid, my dad had a police scanner and eventually I realized that the nearby tornado siren had it's Saturday noon test directly preceded by a 4 digit DTMF on the radio. It's probably a good thing I never had a ham radio

- kawfey 9y agoI was 16 when I discovered this (except instead of DTMF it was a special two-tone dispatch alert), but I somehow had enough discipline to not attempt a replay attack. My (now ex) girlfriend's sister was a dispatcher who I mentioned it to, and about three months later they changed the system. In my college town, there was a tornado siren placed very close to the biggest multistory residence hall. I learned (through the ham radio club) that it had a long history of mischief before my time.
