Patience is the best cure! Many areas of the UK have been subject to high pressure which tends to cause TV signals to travel further than intended so causing interference. Many have reported such and waited patiently without retuning - and their programmes returned. So wait a while and DO NOT RETUNE. All that would achieve would be thwe loss of some programmes.

You are some 20 km from the Rosemarkie transmitter and there are no hills shown as being between your location and the transmitter. Therefore it is likely that a good aerial in the loft should work for you. I use a log36 type in my loft and I am some 30 km from our 'local' transmitter. That works perfectly for us so I'd expect you would get similarly good results as long as it is correctly fitted. You would probably not need any aerial amplifier either.

BBC channels keep pixelating. Aerial is in loft. Any suggestions?

Mike P.

Thank you for your speedy reply. Sorry I missed it initially, the "Email me Updates" setting appears inoperative.

I've managed to fix the issues after some research (via Google) about "Signal vs Quality". Turns out that our Signal is pretty much steady but Quality varies unpredictably. Given that it is predominantly Quality that counts (the receiver's ability to 'read' the encoded data stream from within a given signal), I viewed the booster/splitter amp in loft with renewed suspicion. If that rather antiquated beastie is introducing more noise than expected, the quality would be poor. I secured a replacement device, which also included a 4G filter as a bonus. Installation meant switching the cable-ends to F-plugs. As none of the Midhurst channels fall into the 800MHz range, I figure the 4G filter isn't (yet) needed, so I guess the old amp had just failed in some way.

In any case, after a re-tune, the Humax now reports Quality readings at 100% for all channels.

Thanks again for taking time to reply.

Stef Neumann:

Glad that sanity has returned to your household.

When dealing with signal reception problems both the strength and quality are important. Too much signal strength is as bad as not enough, or sometimes worse. Quality will always vary but the critical issue is whether it falls below a required level so that the 'decoder' can sort out what all the digits mean.

'F' connectors are becoming the preferred method of connection aerial leads. They are reliable if fitted correctly.

The frequency range used by 4G is in the bands 800 MHz, 1800 MHz (1.8 GHz) and 2600 MHz (2.6 GHz). So any transmission that is close to those frequencies could be affected by interference. In your case PSB3 on ch58 and COM5 on ch59 could be affected, so a filter may be beneficial if the 4G transmitters are close by.

MikeP: My (split leads) were put together by a rigger using F fittings, simply because they are less likely to come apart and are a more reliable signal.

BTW - have you noticed just how many people are reporting problems that sound exactly like problems with their aerial system such as loose connections, cables, etc - and yet the transmitters are always to blame!

Yes, I'd noticed that too. Just responded to one such for Malvern and another for Rowridge.

All BBC has gone TV and radio and has been this way since 18:30. I use an outdoor aerial which gives me !0 as signal quality on all the commercial channels. No transmitter news on the freeview page for Tunbridge Wells.

Peter: The transmitter has no reported faults. So logically, the fault lies with you - check your aerial system.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

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.
