    Entropy. The tendancy for everything in the universe to turn to **** eventually, happening for you at 9 years, bugger.

    Okay, we've mostly gotten there now.

    I managed to bypass the amp and now all the Saorview stations are back. Daithi O'Se in HD not normally something I'm so happy to see.

    But, now when tuning the channels, the Freeview channels aren't being picked up at all. Not even in their scrambled "No signal" form. So I'm guessing bypassing the amp means it can't pick those up. But at the very least I assume the issue is indeed with the amp and a new one should bring them back.

    Cheers for all your help The Cush! If you want to PM some revolut details or anything I'll fire you over enough for a few pints.

    The distribution amp is presumably supplying power to the masthead amp for the Freeview aerial. (The green box under the grid aerial.) There will be no signal from this aerial without this powered, so you'll need to make sure a replacement distribution amp also has line power for masthead amps.

    Faulty masthead amps can be a source of interference too, so it could be the case that taking this out has fixed things for Saorview.



  • Registered Users, Registered Users 2 Posts: 15,911 ✭✭✭✭The Cush


    Can we assume there's separate masthead amp and combiner on the mast?

    If so the distribution amplifier is powering the masthead amp. What is the model no. of the distribution amp.

    @Penn The fault could lie with the masthead amp. This might require an aerial installer to check and replace the masthead amp



  • Registered Users, Registered Users 2 Posts: 497 ✭✭Elvis Hammond


    I'm not assuming anything. The top box is an amplifier, the bottom is the diplexer/combiner/whatever.

    This announcement broke into Radio 1 on 87.8 at 11.47, and two minutes later as I was writing this, the station went off air. Not affecting other stations from Clermont at this time.

    Due to essential engineering work our Clermont Carn transmitter will be subject to complete outages of up to 30 minutes between 11:00 and 16:00 on Monday 25th November 2024.This work will affect all Saorview and FM radio services from this transmitter site.2rn apologise for any inconvenience caused by this necessary work.

    Just to close this out, I got a new distribution amp on Saturday and fit it. Most of the Freeview stations came back fine, some didn't (depending on what channel they were coming in on). It was the same yesterday. However today for whatever reason, all perfect. Maybe it's due to whatever works were going on at Clermont Carn as posted above as that was the transmitter serving me, but not going to question it. All is right with the world again anyway.



  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    Are you now getting the Freeview channels again?



  • Registered Users, Registered Users 2 Posts: 35,109 ✭✭✭✭Penn


    Yeah, all channels back I think (or at least all the main ones). Some channels can be glitchy at random, maybe need to retune the telly or reposition the amp in the attic, but for the most part it's all back to normal.



  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    Glad you got it sorted - sort of !

    Your problem rekindled an interest in why my set up plays up —- I have a new combiner / diplexer arriving tomorrow !

    Might get one myself, or maybe bypass it as I don't use the dish. At least I'll have addressed pretty much everything I can internally at that stage.



  • Registered Users, Registered Users 2 Posts: 15,911 ✭✭✭✭The Cush


    Bypass the combiner if you're not using the dish, it adds loss into the cable. Use an F-joiner to join the cables.



  • Registered Users, Registered Users 2 Posts: 5,473 ✭✭✭SCOOP 64


    Can you still get ITV+1 , couldn't find it last night.



  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    Masthead A/B Combiner - LMD3740P Labgear.

    Arrived and fitted now I don't have to get off my backside to switch aerials .

    Good quality unit and in my case in the dry behind the TV.



  • Registered Users, Registered Users 2 Posts: 22,152 ✭✭✭✭dxhound2005

    Penn

    To avoid any confusion the Masthead A/B Combiner - LMD3740P Labgear would replace the combiner on your aerial mast not the satellite dish one. I'm at a loss to know how your masthead amplifier is powered.

    Anyway - as long as it works for you.



  • Registered Users, Registered Users 2 Posts: 35,109 ✭✭✭✭Penn


    Ah yeah, I meant just replacing the combiner in the attic for the dish & distribution amplifier, but as per other posts above, I'm better off just bypassing it entirely. Not going to do anything to do with the aerial externally unless absolutely necessary.



  • Registered Users, Registered Users 2 Posts: 35,109 ✭✭✭✭Penn


    Huh, just went uop to check and I had already bypassed the combiner. Must have thought to do it when I got the new amp.

    Any news on Castlebar transmitter? not picking up anything on channel 25 RTE1, 22 is fine for RTE2 ?

    Here's something I don't understand . I live about 160 miles from Mt Leinster and under "normal" conditions get a good signal on C23 and C26 receiving everything available.

    As soon as there is a "lift" as in the last few days I can be watching RTE1, for example, with a "high" signal when in the blink of an eye it will disappear with a "no signal" message. This can last for a few seconds or hours. Sometimes if I change to RTE2 which is on a different frequency I get a "high" signal other times there is no signal. Conversely it can happen the other way round RTE2 good RTE1 nothing. I know the Carmel transmitter East of Carmarthen use the same frequencies but I've shielded the aerial from that direction.

    It makes no difference if the lift conditions are East/West or North/South it just when there is a lift. As I'm typing the RTE1 signal has bounced from "high" directly to "no signal" and back up again .RTE2 is rock solid on "high".It can also happen the other way round —- most odd and annoying .

    160 miles is a hell of a long way for UHF, are you in Wales?

    I'm partial to your abracadabra,
    I'm raptured by the joy of it all.



  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    Oops it's 90 odd miles sorry!

    I was looking at the distance to the Isle of Man for Manx Radio.

    Yes - Pembrokeshire on a hill !



  • Registered Users, Registered Users 2 Posts: 36,417 ✭✭✭✭Hotblack Desiato


    It's possible that in lift conditions your unwanted signal is nearly as strong, or as strong, as your wanted one.

    Assuming you already have an aerial as big as practicable, as high as possible, and correctly aligned, there's not much more you can do to get more wanted signal - a phased array maybe?

    VPN and RTE Player 😁 (hard enough to get it to work right from over here!)

    I'm partial to your abracadabra,
    I'm raptured by the joy of it all.

    I’m sure there are other sites down? But if the wider community has no power, it may not be being reported.

    There are no notices on the 2rn site about outages due to the weather. The BBC site has a transmitter checker. I used a Newry postcode to search for Camlough faults.

  • Registered Users, Registered Users 2 Posts: 631 ✭✭✭Oscarziggy


    Thanks for the comments about Mt Leinster signals — I have a feeling it's the signals from Carmel on the same frequencies that are causing the problems.

    No lift conditions these last few days and signals rock solid .



  • Registered Users, Subscribers, Registered Users 2 Posts: 1,368 ✭✭✭mike2084


    Only notice I saw on the 2rn site about outages for the storm:

    2rn - Storm Éowyn - 2rn

    Cnoc An Oir all FM and Saorview services still out for me.



  • Registered Users, Registered Users 2 Posts: 852 ✭✭✭marclt


    not sure if this list is being updated on 2rn



  • Registered Users, Subscribers, Registered Users 2 Posts: 1,368 ✭✭✭mike2084


    These services came back on air around 4pm Saturday in my area.

    Due to maintenance work our Three Rock transmitter will be subject to short outages between 09:30 and 17:00 on Tuesday 4th February 2025. This work will affect all Saorview services from this transmitter site. 2rn apologise for any inconvenience caused by this necessary work.

  • Registered Users, Registered Users 2 Posts: 8,757 ✭✭✭dublinman1990


    Is this work happening today instead?

    I turned on the TV today & got no signal from RTÉ2 on Saorview.

    I didn't have any outages from Three Rock yesterday.



  • Registered Users, Registered Users 2 Posts: 8,757 ✭✭✭dublinman1990


    I've have another update about receiving the Saorview channels from Three Rock this evening.

    Ch.30 is giving me 41% Signal Intensity & 10% Signal Quality. Ch.33 has given me the same data.

    It was raining in Dublin yesterday morning. I'm not sure if that work at Three Rock was delayed until earlier today.

    Another update here. I got my Saorview channels back now.

    I had to switch off my Saorview box to get the signal back again.
