Ahh, that explains it. Thanks.

IIRC, one function that was at least handled locally* by Westcountry itself was the four-way split for local news opts? (and that didn't begin until some months after launch?)

Yes it didn't launch till later in but that was one of the reasons they needed a new network to carry the channel to the transmitters.

I remember seeing a thing showing how it was done. The news gallery triggered the sub opts from a panel on their desk, I think they had 4 buttons so each could be opted seperately if need be.

I don't know how it worked technically, I assume the 3 studio outputs went back to Plympton and then out to the appropriate transmitters. Because it was all purpose built it could be that there was some reconfiguration of the distribution every opt out
