.....I think we had RTE Relays up above in Dublin in '78, Ken. Six channels in total IIRC, well more if you take account of the fact that UTV often switched to HTV and BBC NI to BBC Wales for no particular reason. I remember my uncle watching the cricket on a visit from the mainland when it just switched to something else. Even being before the days of remote controls he took some convincing that nobody had touched the set.
We only had RTE 1 up till 1978 and then RTE 2 also till the mid to late Eighties (
and No remote control either).
Then Cork multi channel came along and every Mog in the city tapped in to the exposed lines to get the service fer free.
Then Multichannel changed to a analog box system;
and of course every mog in the city had their box 'Doctored' to also recieve all the premium channels fer free.
