I had assumed that they would have had dedicated telegraph lines from IRN with a "rip and read" service, similar to the BBC?
Did Channel not have a telex connection - or did IRN not have the ability to send the bulletin via telex every hour?
I think what Tony's suggesting, is what I suspected a few weeks back up thread, the NUJ probably weren't over happy about changing any work practice at IRN to additionally feed Channel ? How did sending multiple telexs work BTW, or was each ILR station sent the script in rotation ?
I guess there were telegraph lines rather than telex lines used for sending normal feeds - maybe a mirror of the IRN audio lines?
LBC -> BRMB -> Piccadilly -> Metro -> Clyde with spurs off where required possibly. It would need someone who worked in ILR to confirm.
Oooh, now, in one of the later IBA Tech Reviews there's a diagram showing the IRN dist and cont networks.
I can't remember which one, and my collection is in deep storage at present (long story).
From memory BRMB, Piccadilly, Clyde, and I think Radio West (Bristol) were hub sites. There were also daisy chains, LBC>210 Reading> Victory Portsmouth > 2CR Bournemouth. It'll be on that NTL/IBA memorabilia site somewhere
