If you have any of these devices, you will need to work out which of these is blocking the reception of a Freeview multiplex by turning off the suspect device and then rescanning for channels on the Freeview box.
You can find a list of the frequencies that are not in use at your location by putting your postcode into the My Freeview reception and looking under the "Free RF channels" section.
Non-wideband aerial in some areas
In some places you will need a wideband aerial to receive all the Freeview multiplexes. For example in Central Birmingham, the Sutton Coldfield has multiplex D on an 'out of group', so you cannot view Film4 or ITV2+1 without an aerial upgrade.

I live in IP postcode and have just installe a digitalaerial. Some times I get up to 72 tv stations sometimes only 25. Sometimes up to 7 carriers sometimes only 1 or two. Sometime I lose all radio sometimes all are OK Once received, most pictures either break up or disappear altogether. Some days everything is fine. Why such intermittent quality?
I am experiencing reception interferance of signal quality from Winter Hill. The BBC channels are normal but the signal quality varies on all the other channels from as low as 40%. Is work being carried out and can I expect the interferance to stop at some stage?
Sorry, forgot to mention that this is happening to quite a lot of people, and not just me. Also, we are getting interference on the analoguesignal side of things as well.
Is this really just going to be the aerial/cable/connector?

I live in the BS40 area, and our local transitter in not yet capable of transitting digital TV, however wwe can get MUX1 from venvoe, if it rotate the aerial 180* we can get all MUX's transmitted from wenvoe but we lose local broadcasts (ie we only get welsh news). the mendip transitted is obstucted by the mendip hills, i have tried a new masthead amp, and screen coax downlead along with better a high gain 16dB aerial and longer mast, but still cannot receive any digital broadcasts from mendip. my only option seems to be 2 aerials, one local, and on towards wales, and a combiner/diplexer.
this may have to be done sooner than expected as the whole street has lost BBC2 analogue, as i'm the only one without SKy, then i'm the only one who has noticed!
Peter Thomas: You're not in a good position for Mendip reception. Perhaps you would be OK using Wenvoe Freeview for two TVs and have Freesat for the main TV, so you can have the right BBC and ITV regions?
Living at NN14 4UZ. Got a Philex SLX 32DW loft mounted ariel pointing at Sandy Heath. Up until two weeks we got all Mux's fine but then Mux 2, A, B & D dissappeared. Then yesterday everything else went. Now can't pick up any digital channel. People have said that it is a new very large industrial unit being built @ 1km from house in the general direction of Sandy Heath though not in direct line. Basic fabrication is up but not side walls. Channels started to go when the unit skeleton was fully erected. Any help please ?
can you help - just moved into a new build. Have fitted a widebandaerial (cat 2) in the loft, but have not been able to view any of the ITV & ch4 programmes, plus radio stations are missing. Iam currently using a portable tv with built in vcr.Do i need to mount the aerial outside as advised in others' enquiries on this site, or is it the tv knocking out the signal?
Im using the sandy heath transmitter from CB4 5GX. thanks
Follow up from previous request - I moved the digibox and portable tv into the loft and tried re-tuning with the aerialcable directly into the digibox. After moving the aerial a little, I received the full listing of channels(65) at full power. I then connected the aerial cable back into the two-way splitter ( 2 cables feed the aerial sockets in the house.) When I connected everything to the aerial socket in the house , I have lost all itv & ch 4 channels etc. Do I now need a booster at the digibox end because i'm losing signal through the cabling or is it the splittter thats the problem?
I'm in PR4 which uses Winter Hill. I got a digital tv recorder yesterday, and after doing the automatic scan I got all the channels except those on Mux2. I've tried rescanning to no avail, and manual scanning shows that I'm getting no signal on channel 66.
However, I get a good signal on channel 68 (MuxA) which is also using 64QAM.
Why is there so much difference between the MuxA and Mux2 channels? Is this likely to be an aerial problem, or something else?
I would be grateful for an explanation concerning signal breakup and pixelation of some channels coming via Rowridge ( Isle of Wight) transmitter. The digital signal quality at the moment is appalling. It is OK one minute then breaks up on some channels and reads "This channel is scrambled or unavailable."

since the beginning of the year all c4 and itv channels either broken up or missing virgin 1 and the hits also now breaking up badly.i have the same equipment as before so rf interference not an issue as they used to work fine. the ariel is wideband,i ve tried rescanning and using friends digi boxes to no avail.now other people in my area market harborough reporting same problems what is going on?
I have a TN4 postcode, and loft-mounted group B vertically-oriented aerial pointed NE at the Tunbridge Wellstransmitter. We get Mux 1,2, B and C fine, despite 1 & 2 being "out of group" (presumably because we're less than 3 mi from the transmitter.)
Changing the aerial would presumably give us Mux D as well, but Mux A should be fine with a group B aerial and yet we get nothing. There are no local devices using C42, so could it be interference from the analog C5 signal from Reigate, which is also vertically polarized? Would a higher-gain aerial (which would presumably have a narrower acceptance angle) help? I'm hoping to avoid installing a roof-top mounting if I can help it (scared of heights!)..
SteveD: Even if you are right next to the transmitter, you will not receive channels that are "out of group". Rooftop aerial will give you better reception than a loft one. The larger (the more elements) on an aerial, the more directional they are.

Thank you for this useful site. I thought my problem - and its solution - might be helpful to others. I live quite close to the Rowridge transmitter and should not have any reception problems. However all channels were missing on Mux 2 (ITV) with one of my receivers - a PCI computer card. I tried the solutions suggested for "single frequency interference" on this page but no joy. It turned out that the PC Card - a cheap one - was not very accurate as to frequency. It claimed to scan Mux 2 at 530 MHz, finding nothing. Fortunately the bundled software also offered a manual scan at user-specified frequency - not very well documented. After much experimentation I found it also accepted decimal input - an undocumented feature - and that scanning at 530.1 MHz made it locate and tune all Mux 2 channels loud and clear. I also noticed there was an optimal setting at which it found all channels, and other settings at which it found some but not others. So it is worth trying different frequencies to ensure the very best reception results e.g. in my case I tried 529.9 530.05, 530.1, 530.15 and so on. This may be helpful to other users who have not been able to solve their problem after trying other advice on this page. You will need the means to force a scan at a particular frequency - I believe many set top boxes and bundled software with computer cards will allow this but clearly not always well documented. And you need to know roughly the frequencies you are looking for - documented on the web. Rob White
Based on my own experience of digital reception (postcode: PL27 7HH) and judging by the problems described by others on these pages, there seems to be little "rhyme or reason" behind the most common problems. Such as:
1) Why do I get a worse reception on BBC1 & BBC2 than from any other channel, when they are transmitted at MAX power (and on the supposedly "more relaible mode") and the others are not?
2) Why can't I get any of the (channel) five programmes, even tho' they are transmitted in the same mode and at the same power as programmes that I can receive (albeit from a different MUX)?
The proposed solutions (usually, "get a new aerial") seem unnecessary, given that if the channels I cannot currently receive were transmitted from the same source as those I CAN receive, ditto those that "spit and click" particularly frequently (i.e. BBC channels) then new aerials (and the expense their purchase and fitting entail) would not be needed. Could it be, therefore, that the principal reason I and so many others are suffering these problems stems not from technological difficulties, but from a lack of communication between us, the customers, and the decision-makers? Do the people who run the transmitters know about these apparent inconsistencies? Who can we contact? Your thoughts, and any contact details you may know of, would be appreciated.
I could not pick up any of the freeview channels in mux D after multiple days of trying and rescanning (Rowridge, Isle of Wight live in Poole), what i did to get it working was remove the normal tv ariel link between the freeviewbox and the tv, i.e. leaving only the scart lead between the tv and the freeview box. After re-scanning, bingo had the MUX D channels. Repeated this a few times and seemed to confirm. Hope this help to anyone.

Hi, We have just purchased a new Toshiba lcd tv and dvd recorder, both have freeview receivers built in. On scanning for channels all available channels were found on both units but Dave and E4+1 register as a poor signal and watching them is impossible. With our Nokia freeview box both these channels were fine, and are still so if we reconnect it. Can you advise of any solutions to the problem. We have a Wii attached to the tv, a directional aerial located in the loft. My post code is TS17 5AP.
Grahame Lees: It seems likely that your DVD recorder might have an RF output. If it does, make sure it is not connected to anything else, or is powered off. If you can't get it to use one of the "free RF" channels listed here <a href="http://www.ukfree.tv/transmitters.php?P=TS175AP&G=NZ437141">Find out how to receive Freeview at postcode TS175AP | ukfree.tv - independent digital television and switchover advice, since 2002</a> - does the Wii use an RF output? Loft aerials never provide good Freeview signals, I'm afraid. <a href="http://www.ukfree.tv/fullstory.php?storyid=1107051194">Loft aerials | ukfree.tv - independent digital television and switchover advice, since 2002</a>
I've recently bought a Panasonic home cinema DVD player, and after connecting it I lost the ITV/CH4 multiplex from my freeview (I'm using BT Vision, but the TV's built in freeview has lost them too). After reading this page I realised the DVD player must be causing local analogue interference, however as there is no RF output I'm at a loss as to what to do (other than continually disconnecting and re-connecting the player each time!)
paul: I would check in the new box doesn't have an RF configuration option SOMEWHERE and change it to one of the values that the "My Freeview" page gives you. Another option, if there is no RF output change (as there is no RF output) might be a mains filter, can you explain a little more about what is connected to what via which cables?
Hi l live in Hemel Hempstead in a block of 50 flats, we had our TV aerial etc upgraded for digital by a competent Aerial contractor 2 years ago have had perfect Digital TV reception for 2 years but for last 3 months reception has been terrible, sometimes it is perfect, and we get all channels then suddenly we lose most chanels, it comes and goes like this all the time now, and affects all 50 of us in flats same, Aerials etc have been checked by contractors and are ok. Any suggestions ?
ps it drives you mad.
Ray: Sounds like you need another aerial contractor! Do they not visit when there is a problem? I would guess from your description that you have some form of induction interference leaking into the signal distribution system, or that the power is being disconnected from the distribution system. I would get another aerial company out for a second opinion - when the problem is happening. Sounds like the current aerial contractor is simply saying "it's not me, gov.".
Hello, I was directed to this page following my question re. losing Freeview channel 5. To be honest, NOTHING changed here - I didn't connect anything different, no new games consoles etc. It was simply there one day, gone the next. I'm certainly NO expert of Freeview and don't know how to put this right...
When I lost the channels 5, 5 life etc early this week, I tried re-installing the stations. I didn't work. I've just tried again to re-install and low-and-behold, all of them are reinstated. I still don't think it was a problem this end, rather something happening at Belmont Transmitter.
I lost a couple of channels earlier this week and other channels are freezing. I have tried all the tips on reinstalling mentioned here but still no joy. The stations have been working fine until now so is this a transmiter problem - Mendip area?
Wonder if you can help. Live in Norwich and recieve signal (digital) from Tacolston. Just recently have been receiving poor picture - especially ITV - digital pixilation. The menu shows high Bit interference - what would cause this?
Hi there,i bought a samsung 46" hdtv with built freeview back in january and have had no problems with the channels (have a rooftop aerial) until now.
We have lost the itv multiplex completely and bbc multiplex keeps pixilating and skipping. There is an xbox console only connected to it. I've tried rescanning channels but to no avail.Tried everything ,its only problematic from 2 weeks ago can u help?
Channel 56 is always poor in the Ipswich area I understand that this is due to low power output from Sudbury, however why can't the shopping channels/ community channels be broadcast on channel 56 rather than more popular channel 4/ITV offering.
I have been receiving MUX1 channels from Emley Moor using a loft aerial for at least a year with no problem whatsoever until two days ago when I lost all channels on MUX1. All other digital reception is fine and "Film4" is even more reliable than before. Nothing has changed in the house that I am aware of and I have tried re-setting the Freeviewbox and re-scanning several times to no avail.
