Not sure, Ken... we probably did, possibly dependent on weather. I do remember one occasion c.1975 that my uncle (a St. Lucian immigrant to the United Kingdom of Great Britain and Northern Ireland) was over on vacation and was watching a game of cricket when the (ITV) service suddenly switched from HTV to UTV. As UTV weren't showing the cricket he was extremely perplexed as the system was explained to him - in those days the service was relayed by RTE Relays and that happened quite randomly with the weather being blamed. I'd say if we had remote controls back then he'd take some convincing that nobody had turned it over!
