Hi Liam!

Dave Lindsay is correct about receiving RTE from Blackmountain but if you are trying to receive you need an (elements vertical) pointing towards Newry direction to receive Saorview as the is located at near Omeath. This transmitter transmits on UHF Channel 52 and carries RTE1, RTE2, TV3, TG4, RTE News (from 7pm), 3e and during the daytime RTE Jr. (children's programming until 7pm) and RTE1+1. There are a selection of Radio : RTE Radio 1, RTE 2FM, RTE Lyric FM, RTE Radio na Gaeltachta, RTE Radio 1 Extra, RTE Pulse, RTE 2XM, RTE Gold and RTE Jr. Radio.

Now Channels are going to come at a later time on Channel 57 - no date as yet.

Let me know how you get on.

Regards

Kieran

Mux II should be on 56 Kieran, not 57.

It's rumoured on Boards.ie that some could start in the new year i.e. start of 2014. RTE One HD for example.

PJH: Will it use DVB-T2, or will it be DVB-T so as to be compatible with current devices?

Hi PJH!

I know there was some discussion about the second being on UHF 56 but current information from this site indicates UHF Channel 57 (https://ukfree.tv/txdetail.php?a=SB173735)

Things may change in the next few months but I haven't heard anything at this time.

Thanks Brian.

According to boards.ie it does fire up periodically, but I haven't seen anything since January.

There's speculation it may start in the new year with RTE One HD etc.

Hello,
Can anyone please tell me how to manually find Dave, Dave Ja Vu and possibly GOLD? Would really appreciate it. I have a / combi box and live in the south in Dundalk, Co.Louth, relatively close to the border.

Regards,

Anto: If you scroll up to the list of multiplexes you will see Dave is on the ArqA mux - try a manual for UHF channel 26. Although, the commercial from are broadcast at half the of the public service ones, so you may not be able to pick them up.
