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 - edit now answered
- what change would have blocked this later on - edit now answered
- any historic info on the period it was left open, or personal accounts - still pending, trying other social media too for this

Cool! The same thing happened in #Sweden in 1982, when people discovered some vacant numbers acting like conference calls. They became popularly known as "hot lines". The national phone company subsequently provided some official numbers for the purpose, until 1995.

People would arrange to meet, like your parents did, and there was even a group of more than 1000 youth that congregated in a park in Stockholm, leading to a clash with the police.

@leffe This sounds much nicer than the UK’s approach (recently privatised in 1984), which was to introduce premium rate phone numbers so people could run these at a profit ☹️
