    Folks are there problems with RTE1
    Was working ok up until the other day
    Now I get 100% on RTE2 but signal varying wildly on RTE1 every couple of seconds it goes from 20% to 100 and back

    Were in Wicklow town & used to get our picture from the Greystones transmitter but after a rescan I can no longer seem to get any signal from there
    And instead are only picking up RTE 1 on channel 25 which appears to be the transmitter up near the M11 at the back of the rugby club

    Is this a glitch or do I need to get up on the roof and point the Aerial somewhere else

    Thanks for any replies

    Not sure if you've tried already. Put your details in here to get the optimum transmitter and freqs to tune to.

    Delete whatever Saorview you have, & try a manual scan of chs. 42 (642 MHz) & 45 (666 MHz).

    Yeah if I try that is shows the new transmitter up near the m11 which is 3km
    And was not there when the Aerial went up

    Which means I would have to get up on the roof and possibly move the Aerial round to the other side of the Chimney as the chimney is between the aerial and the transmitter

    Did that last night deleted saorview channels and scanned the Wicklow / Greystones channels 42 - 45
    Found no Channels even though this was working up til about Monday

    Don't understand though how I can be getting 100% solid on Rte2 and intermittent 20 to 100% on RTE 1 channel 22 - 25 picture breakup when I am close enough to throw a rock at it

    I just get the feeling there is something not working right and I could get up and move the Aerial round to the other side of the chimney and still only get intermittent signal on RTE 1

    We're on Tara Hill Gorey, on aerials to BBC in Wales and RTE in Forth Mountain. We're in the shadow of the hill from Mt.Leinster.
    Yes, we're losing RTE1 a lot. I thought it was weather related as we sometimes get drop outs of BBC Wales too.
    Sometimes RTE1 is No Signal but RTE Now works - is that because New Now is SD and less influenced by weak reception than RTE1 HD?

    No installer is going to call to us during this emergency so we're stuck with what we have. Currently I get RTE1 on their web site on my phone and Miracast it to our non-smart telly for which we have a Miracast HDMI dongle.
    We have an old Sky dish out of subscription but Sky only offers UK channels for free, not RTE.
    No point in online ordering an extra booster I suppose, it can't amplify what isn't there.

    Thanks for the info. Do you know when it was installed and where it is exactly? I can check with my installer about redirecting it there although that may not now happen until all this lockdown is over. Is there any online map that shows its coverage? We might just scrape a line of sight along the southeast of the hill to Gorey town.

    For what it's worth I have similar problems with Mt Leinster here in West Wales .
    The signal on RTE 1 can go from "high" on my Sony TV to nothing in the blink of an eye .
    It's been bad the last few days with the high pressure over the UK -- was even getting RTE DAB on a portable radio in the garden yesterday.
    Before starting to type this I was receiving all signals from Mt Leinster at "high" signal -- I've just checked again and nothing being received.
    I have an aerial at 90 degrees to the Mt Leinster aerial pointing at Presli using a combiner into the TV .
    Fairly recently the Carmel transmitter near Swansea changed to CH23 and CH26 - the same as Mt Leinster (bad idea) and I thought I was getting that transmitter off the back of the Mt Leinster aerial -- I now have my doubts.

    I'm sure it's high pressure related -- I've just checked again and RTE2 is rock steady at high signal whereas RTE1 is bouncing between high and good .
    I really don't know the answer.

    How does that happen? Aren't both stations coming from the same transmitter? Wouldn't they both be transmitted at the same level? I'm curious about the physics here.

    It could be the positioning of my aerial - it's the correct group but maybe it needs to be higher / lower .
    RTE1 is on ch23 RTE 2 on ch 26 -- or visa versa - can't find the info at present.

    Mux 1 with RTE2 is on 23, Mux 2 with RTE1 is on 26 from Mount Leinster.

    @sysmod. The maximum effective radiated power (ERP) is the relevant bit. They do not have to operate at the full maximum. A lot of queries here are from people who can get one frequency but not the other from a transmitter site, and it could be down to lower power on one of them.

    Because it's a low powered directional setup, whose coverage is in the opposite direction to where it's needed here?

    There's nothing 'wrong' with RTE1, from any transmitter site. If anyone thinks they're seeing some kind of pattern in replies here, you're not really; it's just coincidence. It's just inadequate receiving setups (again), some of which may have been undone by the frequency changes.

    Line of sight to me from Mt Leinster is 90 miles - when the warmer weather comes along I may change the aerial .
    Mt Leinster didn't change frequencies as far as I'm aware -- I've always used ch23 and ch26.

    It wasn't so much yourself I was referring to, as you're outside the Saorview service area, & I suppose would be more subject to quirks in wanted tx coverage, as well as interference from unwanted sites.

    And yes, Mt. L. has had Saorview on 23 & 26 since analogue was switched off.

    It was all fine until last week. And I've been retuning every day I lose RTE (BBC1 takes its first place on my set).
    Here's how it looks
    https://twitter.com/PatrickROBeirne/status/1243673074005872640

    And now even the online RTE player goes blank after a couple of minutes.

    We're sorry. SAORVIEW coverage is a challenge in your area. Please consult a reputable aerial installer for further information and advice. Although SAORVIEW cannot reach all locations, viewers in the Republic of Ireland are likely to be covered by the SAORSAT satellite in-fill solution. For up to date information please check www.saorsat.ie "

    Saorsat.ie:
    For an average two-storey house or bungalow, 40 km round trip and 1 year warranty, an installation by a competent system installer would cost around €200 fully installed (dish, LNBF, chimney / wall bracket, cable-surface clipped, and installation).

    So I guess we'll face that bill next autumn when the installers are able to work again.

    Find it hard to Believe that there is not something gone to pot at Saorview end
    As my set up that's been working away for years has also gone in the last week with the exact same result as yours
    full rock solid 100% signal on RTE 2
    Intermittent 20 to 100% every couple of seconds on RTE1 with breakup and freezing but seems to work ok in the evening

    I have clear line of sight to the Greystones transmitter prob 20 k ( don't quote me on that )

    No Challenge there
    Box is VU+ Duo2
    Have tried Retune to Greystones but finds no channels

    The RTE 2 that i'm picking up is on ch 22 iI think it was and would appear to be coming from the new transmitter up behind the rugby club 3 km away

    My mate who we put in an Arriva box for lives down near the Gaol has no problems getting RTE from Greystones but he is down below Ballyguile hill and would not get any signal from the new transmitter

    So my guess is Bleedover / over spill interfering

    Might have get up today and move the Aerial round to the other side of chimney for clear line of sight of the new transmitter

    It's possible you'd get Forth Mtn. back with an aerial adjustment or change. Kippure might even come in on its new frequencies, depending on just where you are in relation to the hill.

    Does the chimney totally screen the aerial from the new transmitter? Is there amplification in your setup?

    That Wicklow transmitter is the same power as Greystones & it's a lot closer to you, but I don't see why it would have started causing problems only in the last week.

    There is no amplifier

    I put this up a good few years ago when I first got an Amiko Alien

    I used to work for a crowd called Cable and Utilities and we used to install the MMDS service in Wicklow a long time ago

    The new transmitter would be partly obscured by the chimney
    I would imagine half of the aerial would be sticking out enough to be caught

    Installed by someone competent, who ensured there was a decent signal at the TV?

    If that's the case, the installation has likely deteriorated since then, & there's no margin for little variations in signal that shouldn't be noticed at all.

    Finally got off my rear and re positioned the aerial for a clear line of sight to the transmitter up the back o the rugby club
    at the mo the signal is 100 % for both RTE 1 and 2
    Usually started to act up mid afternoon so I will see how it goes

    I have Saorview with an indoor aerial as a standby in the kitchen. I am in Dublin 24 and reception from Three Rock was ok until yesterday (not great but sufficient for news, etc). It has suddenly saying "No Signal" no matter where I place the aerial. I have checked with Saorview and the recent change should not be affecting me. Has anyone had a similar problem? Thanks.

    Yes, we get it from Forth Mt. We're on the opposite side of the hill to Kippure. Now that lockdown has eased we called our local installer who said that RTE had changed its frequencies (shouldn't they announce that to the viewers somewhere to save us all this uncertainty?) so he installed a new amplifier, replaced the splitter by a diplexer - BBC and RTE aerials come down the same cable - and we got RTE back. €150. It still went off briefly the other evening so it's not perfect but then BBC dropped out too although we've a great height to get it directly from Wales. We haven't had to retune again.

    Most of those indoor aerials are rubbish

    Of course the best option is an outdoor aerial, but if you can't do that then something like this could be used indoors:

    https://www.freetv.ie/red-group-a-uhf-aerial/

    I've got a similar Blakes aerial looking out through a dormer attic window in D22, it's passively split in two and then one leg of that is passively split in four :eek: , no amplification, but I still get very high strength and quality at all receivers even with about 1/8th of the original signal (oh and it's not even grouped, it's a wideband.) D24 should also be a strong signal area unless you have local obstructions maybe.

    It'll need to be aimed roughly in the direction of the transmitter, but you may be able to hide it on top of the kitchen presses. Even if you have to hacksaw a bit off the end it'd still work better than the usual indoor aerial...

    Scrap the cap!

    I have been using an old PC running LibreElec with a DVB-S2 card as a PVR on and off for some years. I bought a Realtek RTL2832 based DVB-T USB tuner to add Saorview channels some time ago but couldn't get the two EPG displays working simultaneously. I parked Saorview / DVB-T at the time.

    I've just reinstalled LibreElec (v9.3.2) thinking that things might work ok now. However, I can get no channels at all on DVB-T, selecting Kippure as my mast, as before (using dvb-usb-dib0700-1.20.fw firmware). I'm wondering if this is because the frequencies changed and the info loaded by TVHeadend is out of date or if this USB DVB-T tuner is no longer usable. I have seen a suggestion a kernel update may have broken it, another that I need to renumber a "frontend", advice that I shouldn't select "auto" when scanning etc. I haven't yet hit on the right combination of tweaks. Would like to just have this work. TV works fine; there's a good signal on the cable.

    Advice?

    (I might be interested in a single PCI board with both tuners or a guaranteed working with Linux DVB-T board)

    I suspect it is out of date mux frequencies if your local transmitter changed frequency.
    That should be easy to check in TVH - Configuration - DVB Inputs - Muxes.

    Empty placeholders mostly ...... with a few test channels thrown in.

    You only need to map the actual channels you wish to view in TVH, and only those will show in the channel list.

    Yes, we get it from Forth Mt. We're on the opposite side of the hill to Kippure. It still went off briefly the other evening so it's not perfect but then BBC dropped out too although we've a great height to get it directly from Wales. We haven't had to retune again.

    The difficulty is that Forth Mt. and Mt. Leinster share frequencies with Carmel in West Wales. The same frequencies (33 and 36) are also used by the Haverfordwest transmitter (although different polarity). As a test, if you lose Forth Mtn again, see if there is anything on Ch.29 as this is Freeview HD from Carmel.

    There are a lot of empty channel IDs broadcast on Saorview, and only 2RN know why.

    My setup just ignores them as far as the EPG is concerned, I didn't have to do anything.

    Using LibreELEC on a Raspberrry Pi 3 with Tvheadend, clients are more Pis with LibreELEC, computers/tablets/phones with Kodi

    You'll need two DVB-T tuner sticks if you want to record a channel on one mux while watching or recording a channel on the other mux.

    I got a lot of good info on this thread : https://www.boards.ie/vbulletin/showpost.php?p=104172148&postcount=44

    Scrap the cap!

    OK.

    Don't know if this still counts as lost channels but seem to be doing something wrong in getting all the channels I want mapped as services and showing up in the EPG. Currently getting just the terrestrial channels.

    I first got the DVB-T sorted out by removing the DVB-S tuner card and manually editing the Kippure muxes, then enabling the channels I wanted and mapping the selected channels. I then added the satellite tuner back, and tried to repeat this but neither mapping selected channels nor all channels appeared to work.

    The mapping stopped right away (too quick?). However,

    Configuration, DVB inputs, Networks

    shows mapped services as follows

    DVB-S 823
    DVB-T 22


    It's so long since I last did this I can't recall the proper sequence of steps! and searching for help yields all kinds of irrelevant information. Seems I have a separate step to take in enabling the channels via

    Configuration, Channel / EPG

    Currently, this is only showing terrestrial channels as enabled and this is, indeed, all I've got in the EPG, but the mapped services count is 921, not 845 (sum of 823 + 22 above); not sure why. Presumably I can just enable the channels I want now but the list of available channels includes things I didn't want (because I hit map all services? /eyeroll, /bad language).

    What I intended to do was

    1. Scan muxes to get list of available channels
    2. Exclude encrypted channels, and others I know in advance I definitely don't want (shopping, adult etc)
    3. Map them to services
    4. Get EPG working for selected channels
    5. Disable any I subsequently decide I don't want

    Correct approach?

    For someone who only futzes with this reluctantly every few years this is a slightly tedious rediscovery process every time. I haven't yet encountered a straightforward step by step guide directed at setting up both terrestrial and satellite tuners with an integrated EPG; IPTV seems to be where the eyeballs are!

    Haven't added a DVB-S stick to my headend Pi, so I don't know.

    @PJtharsaile

    The scanning of muxes on Satellite can take a very long time, particularly if only one Sat tuner is present.

    You can watch progress in TVH - Status - Subscriptions

    I would be inclined to set up the scan over night when nothing else is accessing the tuner.

    I show some 90 muxes with 1200+ channels.

    After such a scan finishes you can select the channels you want to map and they will appear on the Channel List.

    From there I generate a list of all the channels I have mapped, and manually arrange that list in my preferred order in a text editor.

    From then on I can use that list to auto map only those channels (having deleted the manual mapping done earlier).

    From time to time the list needs editing as channels become available or are dropped or move mux.

    This kind of stuff is more delt with in the HTPC section I think

    Thanks. Yes, I realize this should now really be in HTPC.

    Observation: I had a quick look at the TVheadend.org site and github and related places and didn't see anywhere I could post the updated frequencies for Kippure. (I did tell Google that it's first result for "Kippure frequencies" was useless, as it offered an opportunity to do so, and gave them the correct info. 2rn's most prominent result was also out of date)

    I was unaware of the possibility of making a list of channels and editing it with a text editor. Thanks for the tip. I found this now that I know of this https://docs.tvheadend.org/Appendices/faqs/

    I'm not clear on whether the resulting file is just for reference (deciding on channel nrs) or if it can be loaded back into LE. I'll revert on the HTPC section if I need help. In the first instance I just want to get selected terrestrial and satellite channels in the same EPG.

    This thread is one where this list is mentioned so should provide some info for you.
    https://www.boards.ie/vbulletin/showthread.php?t=2058075201

    This is the Linux command I used to generate my list from my mapped channels.
    I then arranged those entries in the sequence I wanted them to appear, and saved the file on my PC for safe keeping.

    I am then able to use that file as my own bouquet file in tvheadend (all other bouquets disabled) and TVH passes the list to Kodi on the clients along with 7 day EPG for each channel.
    curl http://192.168.1.12:9981/api/channel/grid?limit=999 | sed 's|},{|}\n\n{|g' | sed 's|"name":|#DESCRIPTION |g' | sed 's|"icon":"picon://|#SERVICE |g' | cut -d ',' -f4,5,6 | sort -n -k2 -t :| sed '/./,$!d' | sed 's|.png||g' | sed 's|"||g' | sed 's|_|:|g' | awk -F, '{print $1" "$3}' | sed 's|#|\n#|g'   >> MyBouquet.tv

    No problems on either mux from Three Rock anyway. What were your signal strength/quality readings like when you did the scan? If marginal then a change in the weather could be enough to throw your signal off the "digital cliff". Pretty much anywhere in Dublin should have a strong signal so check out aerial/cabling/plugs.

    I think its the cable ive running from the VU tuner to TV... its a male out connection from the VU tuner and ive a male to male adapter. I think id be better with a female to male cable

    Those "cable joiners" aren't ideal but not usually a problem either.
    You said the VU had lost channels so the problem has to be upstream of that.

    No they were actually fine on the Vu.. we did have thunder and lightning so maybe that effected.. how can I measure signal strength?
