The symbol shows the location of the Hannington (Hampshire, England) transmitter which serves 470,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Hannington (Hampshire, England) mast?

Appreciate the reply Dave. That information gives channel numbers, not frequencies. For example. BBC4 HD has a channel number of 106, and on my media center (the box having the problem), it has selected 561.833Mhz (quality 33%) as the 'best'. It has alternatives of 562Mhz (but shows 0% quality on that), and 562.167Mhz, also with 0% quality). When I select the channel, I can see it trying to lock on, and there is something there (briefly), but then I just get a 'weak or no signal' message. As I said, all other channels/muxes are rock solid.

For the HD channels I'm interested in on COM7, this is what I see;

BBC News HD (C 107) 561.833Mhz
C4 + 1 HD (C 110) 561.833Mhz
4Seven HD (C 111) 561.833Mhz

I do have locator info for each channel as well if this is of use.

Other working HD channels on different muxes seem to lock onto the other side of the frequency, for example BBC 1 HD locks onto 618.167Mhz, and the picture is fine. I've tried manually changing the frequencies (media center allows that), but it didn't make any difference - infact, there was no signal at all reported there.

I had an engineer in earlier in the week to resolve a different problem, and he verified signals received from all muxes (via the masthead amp) are good (about 65db or up), and gave the aerial/amp a clean bill of health (once we'd replaced the PSU, which had bust).

Tony: I don't know then. The UHF channel numbers and frequencies are given above, in the light green box with the text in slightly darker green.

The frequency of COM7 is 562MHz. The frequency of PSB3 (BBC One HD etc) is 618.2MHz, the +0.2MHz owing to the positive offset on the channel.

Things like HDMI leads and USB leads can interfere with RF signals carried in cables when they are run together. Try removing HDMI, USB, ethernet and other digital communications cables from the mix, if possible, in order to test this possibility. See if things improve. If it turns out to be the issue then use an aerial lead that is better screened, using the solid core stuff if necessary.

I had a new aerial cable from the main socket that feeds the masthead amp made up by the engineer, so that is all fine. Signal levels are good over the downlevel cable from the amp. I split the feed from this connection - one to the TV, the other to the media center. The TV reception of COM7 HD channels is perfect, it's just the media center. I really just wanted to check the exact frequencies I should be expecting, as the TV doesn't give that type of diagnostic information. Knowing that COM7 should be on 562Mhz (not above or below) is useful.

It's a strange one - not a deal breaker, but one of those frustrating 'why isn't it working type problems'. I did notice from the chart that the COM7 (and soon to be COM8) require a 'W' type aerial group, but as I said, other TV's in the house receive COM7 channels fine, so I don't think it can be that. The aerial checks out anyway.

Guess I'll have to keep digging then.

Tony: Judging by what you have said would suggest that the best policy would be to concentrate on making sure that the tuner fitted in your media centre has the latest software installed, as the nature of your problem is very similar to that experienced on a number of Freeview boxes whereby they were unable to receive HD channels from two separate HD multiplexes at the same time, the BBC being aware of the problem albeit being unable to do anything about it, as the fault was with the Freeview boxes tuners and not anything concerned with the composition of the signal.

I am not saying that your box is afflicted with this problem, but purely for a test you should blank out "all" channels stored in the tuner followed by tuning in the COM7 mux on C32 / 562.0Mhz, if by any chance this works, see if you can add the main BBC1 HD / ITV1 HD Mux on C39+ / 618.2Mhz.

By the way, what brand of media box is being referred to? and does this have some form of built in tuner or are you using a dongle?

Tony : In addition to that said, should you still not be able to receive COM7 on the single tune test procedure referred to, what strength and quality is COM7 (C32 / 562.0 Mhz) being received at on your TV?

Six months ago I installed a second aerial on the roof to pick up local news from Hannington as an alternative to Crystal Palace. The aerials are routed through a Triax 3537 combiner. 2-3 months ago the signal for BBC South (Channel 45) deteriorated. I have only recently checked this out and find that it is only channel 45 that is causing problems. Channel 42, ITV Meridian, continues with a good quality steady signal (strength 70% and quality 100%- measured by the Samsung TV diagnostic) but on channel 45 the signal strength and quality leaps up and down between 0 - 50% . A separate TV at the other end of the house suffers even worse refusing to display any picture most of the time. I have bypassed the combiner and this does not solve the problem. I suspect some local interference but can not isolate what might be causing the problem. I would be grateful for any suggestions on what I should check next?

Your comment please
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.
