I don't know what works were done in Limavady over the past several weeks but I had been hoping that the reception would improve afterwards. Now .. I can only get the BBC mux without breakup. Even the Channel4 mux is unwatchable, despite it being the "same" signal strength. All other muxes are breakup up to the point of being unwatchable... Looks like either the signal was shielded more and more or the signal had neen turned down post-works...

Francis Byrne: According to the post above yours, there is still transmitter work taking place this week. I would fully expect the signal to be restored to the same level as normal once the works have been completed, but it looks like they haven't finished yet.

Hi Steven,

Thanks for your reply. Yes, the reception did improve at the weekend but last night, Channel 4 was unwatchable again. I didn't see any further work mentioned in the mast, so am fearing the worst on what tuning has been done on the signal... I just had my aerial tested in August by a local TV aerial man, so I guess I might just have to rely on the nearer Freeview lite transmitter at some point soon.

What really gets me is that the signal used to be perfect back pre switchover - the 800w of power was enough for here .. but the boosted 10kW (COM) and 20kW (PSB) are hard to tune in. Pop (channel) and those on that mux have only occasionally been strong enough over the last 2 years or so.

Thanks again for your reply - the website is a regular visit for me!

There was some quite variable "Tropospheric Ducting" around over the previous couple of days which could well have been responsible for some disruption to reception. That should have now cleared and your reception should hopefully be back to normal.

Hi Chris,

Thanks for your reply. Do you know if there are any weather conditions that might be affecting reception at the moment? Even BBC is breaking up for me today .. and it's the only mux even partially coming in.

Thanks and regards

Francis Byrne:

Hi Francis.
Some predictions were showing the possibility of some weak ducting, but one showing possible unstable air masses earlier in the evening when heavy and/or scattered rain can disrupt signal paths with rapid variations in signal strength, it can be more pronounced at night and also ahead of warm fronts. A warm front was forecast with the rain that's moving through but the front should now have passed.

Whilst I know you are in a marginal reception area, I'm slightly surprised that things are so variable and, for example, using your paper shredder causes the signals to break-up!
I'm trying to think of anything that's not been mentioned as well as the best way of trying to eliminate any other possibilities however unlikely they might be.

Let's check the obvious silly first, at any point when you've retuned, have you checked you're still tuned to Limavady's UHF channels and not inadvertently picked up a weaker signal from another transmitter. They are ( as I'm sure you know) C41,C44,C47,C40,C43,C46 in the order PSBs1-3, COMs4-6.

I know one thing i don't see mentioned anytime previously, especially as you've mentioned a Freesat box, do you have anything connected with HDMI cables? HDMI has been know to cause interference in some cases and the leads should be kept well away from any aerial or flyleads especially if those aren't high quality double screened coax.

Do you still have a DAB aerial diplexed into your aerial lead? If so where is the diplexer, is it out on the roof or is it internal ( or anywhere you could easily disconnect the DAB aerial to see what effect (if any) it has on your Freeview signal strength and errors.

You mentioned about the possibility of maybe having to rely on a nearer Freeview Light transmitter. Which one would that be, would it be Strabane by any chance? Albeit a very low power relay (400W) it supposedly has some coverage into your area, it's also vertical polarisation not horizontal as Limavady. It's also on Planned Engineering this week!! The only reason I mention it is that aerials can be funny things, they have reception side lobes and are capable of receiving different polarisation in some situations. If it is Strabane you could out of curiosity (without moving your aerial of course) try a manual tune for it's PSBs1-3 on UHF C32, C34, C35. If nothing, try again next week if it's no longer on Planned Engineering, just to see.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
