Hi. I live in the Republic and can get most of the . When I re-tuned this afternoon I had ITV3 ITV2+1 5USA and some others. However around 5 P.M. this evening the channels on COM4/SDN disappeared. Does anyone know why this might have happened?

After a day of retuning quite a number of TVs I noticed the following on EPGs

TVs with put the NIMM RTE from at 51 52 and 53.

Those with aerials for Claremont Cairn RTE, they appear between 800 to 807.

The four Northern Hd appear high up the as well so do check your full EPG or channel guide.

From checking the Claremont Cairn today a amp is still required at least in the Antrim area.

Thanks for your comments..
I can receive the multiplexes from both local relays here in without a problem so
the exercise (more of a technical bit of fun really) was to see if I could receive
more by receiving the multiplexes which are not on my local relays directly from a main site. However yesterday after switch-over the levels on the SDN, ARQA and ARQB multiplexes from are much, much lower(as I had feared due to the lower transmitter power ) than the BBC and D3+4 multiplexes so it's not really practical unless I use a huge high- .
I have as well so can get them that way.
Thanks

Hi,

I live in Newtownabbey and my TV is picking up BBC HD, BBC One HD and UTV HD. I haven't seen any of the RTs just yet but I'll do a bit more checking some other time.

I had to retune some elderly relatives' TVs and last night. One set was in , which we got 21 TV channels and 14 radio. This was on 2 TVs. From the looks of the EPG, it looks like PSB1 and PSB2 channels mainly. The other relatives in Ballyclare however were getting a full 120+ channels it would appear.

I also checked with my brother if he rescanned my dad's TVs, who lives just south of the Border in Louth. He said that he also has 21 channels.

Why would this occur? Incorrect aerials and/or wrong direction?
