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…
