You’ve got it mostly right aside from a few Hz. The ESC-2020 originally shipped with 450Hz, however after a silent test or even upon installation it would set itself at 435Hz. A revision was made later in its life to correct it to 560Hz, however some would drift down to 530Hz, and some came like that or are permanently stuck there.

Does anybody know what the pitch the SONGS model 120 is? As it’s kind of hard to tell because you’ve got both overtones and undertones, plus on duderocks5353’s YouTube channel, the model 120 he filmed with the makeshift blower sounds like it has a similar frequency to a sentry 3v8 Which would create a minor third with a federal signal STL – 10
