Terri: Have you checked for any loose or damaged cables or connections? Are all of your TVs fed from the same aerial?

During the summer we can and do get what is called "lift" radio conditions, during these summer periods associated with high pressure VHF FM, DRAB and UHF TV aka "digital TV" may be lost for hours on end, other stations may be seen French TV can be seen, only to disappear hours later. This is normal occasional behaviour of Radio and TV signals. There is now't you can do apart from using freesat. Apart from ensuring you are tuned to the local appropriate transmitter site. Retuning of course under these conditions will achieve nothing apart from un-tuning the stations when normal conditions return.

colin1951uk:
Well, if you are getting 45% at Eastleigh, I'm not so surprised that by Alresford it gets down to 0%. However, there is something seriously amiss with COM7 (ch 55) from Rowridge. Com8 (ch 56) comes in here at a signal strength of 90% with a 0 BER and all the other multiplexes are up around the 98% mark. Before the switch, Com7 (ch 31)was always the worst at 74%, but never so bad as to be unavailable.

Pre-switchover, the signal strength of COM7 was meant to 24.4K with Com8 down at 18K. To get this bad, they must have reduced the signal strength down to sweet FA. Even before digital switchover we got all the multiplexes at often low power levels.

Maybe the transmitter output mask has been configured wrongly. That seems to be the only way COM7 could have got so bad compared with Com8.

Dave Watson:
I had a similar problem and it turned out to be the aerial was oriented for Rowridge's Vertical Polarisation transmissions. Rowridge broadcast this to reduce co-channel interference from the continent.

The recent retune didn't just shift COM7 and COM8 out of Group A, which probably includes most aerials in its catchment since it has been a Group A transmitter for 50 odd years. It also stopped transmitting them in VP completely which is why, like you, I couldn't get anything of channel 55.

If so then you have a choice:
1: Change the aerial orientation from VP to HP and risk loss of signal quality on some Muxes in good weather or
2: Keep the VP alignment and watch BBCNews24 and the other COM7 & 8 channels on SD/fuzzyvision - less inclination to fork out for that new 4K HDR TV.

I took Option 1, but the Bank Holiday weather saw Mux D3+4 quality going all over the place despite a strong signal, which I assume to be the DTV effect of co-channel problems.

A number of people here in Ferndown have lost at least the BBC HD News channel that was 107. Now if we try to use 107 the TV almost immediately re-tunes to whatever channel you're watching.

I see above that the March/May re-tune included a switch that included Channels to 55 & 56 and that we may have to have a new aerial to tune into this. This hardly seems fair?

Kind regards,


Martin

Ken: COM7 & COM8 were never broadcast with vertical polarity from Rowridge, they were only ever horizontal before the recent frequency changes. Perhaps your aerial was just less effective at rejecting the horizontally polarized signal on the old lower frequencies when mounted with the elements vertical.

Martin G Nash: If you don't have satellite or cable you may be eligible to have a replacement wideband aerial fitted free of charge if the missing channels cannot be restored by manual tuning. This can be arranged by contacting the Freeview Advice Line (see link below).

I have lost channels 106 to 201 and retuned several times including complete retune by Freeview staff i.e. Removing aerial etc. Tv is only 12 months old and new aerial installed in loft with no effect. Please advise if I need a wide and aerial. Regards

Colin Hobbs: You are missing the com7 and com8 multiplexes. This page still shows these as on UHF channels 31 and 37 respectively but they have moved to UHF channels 55 and 56.

This change means a wideband aerial is now needed.

If you look at the top right of this page you will see an envelope icon, and next to it a link with the postcode of the Rowridge transmitter.

Clicking that link will take you to a coverage checker page where you can enter your own postcode by clicking "Change address" and see the predicted coverage for your location.

The message above yours from StevensOnln1 details how you might qualify for a free aerial.

Hey StevensOnln1,

Do you know if anyone has been successful getting a replacement aerial / engineer visit from freeview?

I have tried phoning twice and both times (oddly I seem to have got the same guy) was told the same story about low power and there's no way I would be able to get COM7/8.

I feel like I'm being fobbed off. I asked directly about an aerial upgrade last time and was told it wouldn't help.

Thanks,
Tim.

Hey Mike,

Thanks for your reply,. I'm in SO40 8DZ. Always used to get excellent signal from com7 and 8 before they moved.

I'm definitely on rowridge, also my aerial is pointing towards the Isle of Wight so it's s definite yes,.

If you think I should get good coverage for channels 55 and 56 from here, I'll be more direct with freeview.

Thanks,
Tim.

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.
