Basically, anyone served by a relay transmitter - that's anyone in Kintyre who gets Scottish programmes - will only get what's known in the industry as Freeview Light. That's been known since at least 2005.
Freeview Light currently means all the BBC channels (including the additional digital services), STV, STV+1, ITV2, C4, C5, C4+1, More 4 and E4. People with Freeview HD equipment will also be able to receive BBC1 HD, the BBC HD Channel, STV HD and C4 HD.
There are two reasons why the full Freeview service won't be available on relays. The main one is that the other parts of Freeview are a purely commercial operation. It simply doesn't make economic sense for these businesses to invest millions in building a national transmitter network - several hundred transmitters to reach about 10% of the population. This is especially true as the vast bulk of people in "Freeview Light" areas already have satellite tv so can pick up these channels anyway - they'd be spending good money for little or no return. There's also a shortage of frequencies in some areas.
Some people have argued that everybody pays the same tv licence so everybody should get the same level of Freeview service. Well, the tv licence pays for the BBC and has also been used to support digital switchover for other broadcasters with public service commitments. It doesn't exist to allow shopping channels to get extra customers.
The best option for anyone in Kintyre who doesn't want to subscribe to Sky but who feels Freeview Light would be inadequate is to buy Freesat. Basically that means getting a satellite dish and a set top box installed for a one off payment of £150 or so.
http://www.freesat.co.uk. That's what I've got at my place in the town.
The leaflet I've seen from Digital UK makes it clear that some services aren't available on relays so I hope there's no local confusion. I've also heard a few people in the town say that they think they NEED to get satellite by May as "aerials will stop working". That's completely inaccurate so I hope nobody's been giving out delberately false information.
Here's exactly what happens.
MAY 11 - BBC2 analogue will be switched off for good overnight. At this point, Freeview boxes will start to work in Campbeltown for the first time and all the BBC's digital channels will be available. If you want Freeview, it might be an idea to buy your box just now ready to install then. Most decent tvs made in the past 5 years or so will have Freeview built into them so will just need to be reset.
MAY 25 - BBC1, STV and C4 analogue will be switched off for good overnight. At this point, the rest of the Freeview Light channels will become available and boxes or tvs with built-in Freeview will need to be rescanned.
Existing aerials should work fine as long as you get a good analogue reception. I think some of the relays in North Kintyre may be switching a month later than Ctown as they are linked to the Blackhill transmitter rather than Darvel. Analogue tv from Northern Ireland will still be available for another year or so...
How many people in Ctown still watch analogue on their main set? I reckon 80-85% of people have Sky or Freesat now judging by the number of dishes. Switchover is increasingly an issue for portable sets. Oddly, though, I know people who still watch, say, BBC1 on analogue and only put on their Sky box when they want one of the other channels. This is madness as the picture on satellite is far superior to the one on analogue. If you have satellite, you'd be better off using it all the time.
