one of the early, pioneering #phonephreaks

Yea, I heard the #offthehook #2600oth radio #wbai and podcast folks talk about him over they years, since the 1980s.

Thx for the reminder about the doc at #sundancefilmfestival

"Josef Carl Engressia Jr., aka: Whistler, later known as Joybubbles...He could whistle a perfect 2600 Hz tone"

One clarification gathered this weekend- Capital Radio was broadly 24h so this would have been available on the shows without phone call-in. I originally assumed it was happening while it was off air.

I’m honestly dreading asking my dad, despite him (still) being a telecoms engineer. My mother has clarified that this was before he had any knowledge in the area - once he did he was merrily installing what the American phreakers would call black boxes (which he called ERIC) into phones for friends, family, and plod from the local pub…

Oh my goodness. I think this is the only place on the internet nerdy enough to help me locate this info.

My parents met on a what was effectively an unofficial chat room hosted by capital radio (London). In the 1980s, Capital Radio used to leave their switchboard open at night (unintentionally, they didn’t realise it was happening) and people would call the regular radio phone and just end up in what was effectively a giant group call for Londoners late at night. (I say Londoners due to the reach of the radio rather than the phone line itself, people wouldn’t know the number unless they listened in).

I understand they changed how the phone system worked later in the 80s and closed this loophole off.

So what I’m after is…
- the nature of the switchboard that allowed this to happen
- what change would have blocked this later on
- any historic info on the period it was left open, or personal accounts.

My mother would like to clarify for the record that a friend got her onto the phone line, she was “too cool” for the fully licensed and legal capital radio and listened to mainly pirate radio, notably Horizon Radio #radio #capitalradio #phreaking #VintagePhoning #1980s #retrochatroom

You might be amused to know that my mother is now deeply bored of the phone kit and phone system details I am showing her (please don’t stop sharing it, I’m loving it) but I suspect my dad would be bored instead about the radio and human interest aspect of this (and would also be deeply squeamish to talk in detail about meeting my mother, someone he broke up with over 30 years ago) so it balances out l reckon #radio #capitalradio #phreaking #VintagePhoning #1980s #retrochatroom

Long before the internet, some phone networks were hackable by playing a single tone at 2600Hz.

Whistled into a phone, it could grant you unrestricted access. Do you have the vocal chops to be an old-school phone phreak?

I built a web app to test your ability to produce the legendary frequency. You won't get free long distance calls but you will get some honor in the knowledge that you could have been a cool hacker. 😎

I am sad to say that I can only whistle up to 1100Hz... But my wife (a long time woodwind player) is able to consistently get it.
