#2600Hz
something redeeming to me, at least;

the recordings on the answering machine in wayne tower have 2600Hz chirps at the end of each message

Cap’n Crunch wasn’t blind but popularized the whistle, Joybubbles was and he could hit a 2600hz tone perfectly without the cereal box whistle, he could dial by whistling himself

Born blind in 1949, a 7-year-old bypassed the AT&T network to make unlimited free calls for 14 years just by whistling a 2600Hz tone with zero devices. It took engineers nearly two decades to catch him before he became a Buddhist monk named Joybubbles.

2600hz is E7 minus 24 cents so could a trombone feasibly act as a Blue Box?

The notorious Captain Crunch whistle. A prize included in Cap'n Crunch cereal boxes in the mid to late-1960s. The cereal company didn't realise the whistles emitted a 2600hz tone, a sound that could trick telephone routing equipment into giving people free long-distance telephone calls.

heck, I half-expected it to be tuned to 2600Hz ;)

Bonus: this BE-9000 wasn't outfitted with MF signalling, but I can send a 2600Hz wink down the line in tone output mode on demand

here's the Sage 930A setup in Far End Responder mode acknowledging the wink and responding to it with its reply tones

You know you’ve met The One™ when something like this inspires a fabulous conversation.

Where my 2600hz peeps at?

The phone to me was the closest thing to God on earth

If you’re noticing a similarity between Engressia and the character Whistler in Sneakers, that’s not a coincidence

#Joybubbles was curiosity given human form
