Hi

We receive from rowridge, aerial is horizontal postcode is po34 in the last week we've been experiencing problems on Quest (https://ukfree.tv/mapsofsignal.php?c=25) and other channels on this c25.

We had full strength signal on all before the last 'new channels found' retune last week.

We have good sight of the transmitter but before I start climbing the roof and checking the cable I thought I'd check on here and I see someone else saying the same so I'm wondering could it be interference due to the Isle of Wight festival - stages, funfairs and additional mobile masts brought in ?

Or could it be 4g ? I don't really want to go buying filters if they're not needed.

Similar issue to you Damian. Receive from rowridge to PO3. Last week all was well, not receiving the BBC channels and ITV3.

MikeB: Just a note to say I tried a dvd player and the problem persisted and as I haven't got a spare scart lead I finally managed to borrow one from a friend. On using it hey presto the shadows have gone! So I'll have to get a decent quality lead off of Ebay (where I live all we have is Argos and their leads are rubbish) and that should be an end to the matter.

Cheers and thanks for the tip.

Colin1951uk: Try your local Poundland. I got a 2m 'Belkin ProAV 1000' (!) for a pound. Scarts are really cheap because they are going out of fashion. As long as its decently shielded, it should be fine.

When we get a flat screen, it will want to use HDMI, which are less prone to this sort of thing. Its strange how its often the small things which cause the most hassle - glad you got it sorted.

Hi there,

Do you know why the Rowridge transmitter channel 31 (BBC News HD, BBC4 HD etc) is polarised horizontally and only 10kW as opposed to the majority which are vertical and 200kW?

Regards,

Ken Peck: Officially the COM7 mux is intended to encourage viewers to equip themselves with receivers that support DVB-T2 ready for a possible transfer of some or all services to DVB-T2 transmission from possibly as early as 2018. It is a low cost network which re-uses equipment taken out of service at DSO. The power of the transmitters at each site, I suspect, is somewhat experimental, but is set to cover the largest section of the population served by the chosen transmitters, whilst causing the minimum level of interference to other areas using the same frequency. In the case of Rowridge, most viewers living reasonably close to the mast will still be using horizontal polarisation, so it was decided to use horizontal polarisation only, thus saving the considerable extra cost that would have been incured by transmitting an additional vertically polarised signal. The lower power of C31 is necessary as Oxford shares this frequency for Com7.

My Sister who has recently moved to Bournemouth rang me today (I live in Berkshire) to say that all of her BBC channels have disappeared !!!!

Further telephone investigation including appropriate retuning shows that it is only channel 23 channels that seem to be missing, all others from the Rowridge transmitter are working correctly with good (85%) signal strength. Whereas channel 23 has on 5% signal strength.

Does anyone have any clue what might be the problem please.

Regards

Mike

I live in SO40, receiving from the Rowridge transmitter. At some point on Tuesday (26th August) I lost signal from all channels in COM7 and when I retuned my digibox (Panasonic DMR-BWT720) the channels were removed from the guide entirely.

I was pretty annoyed because I had a timer set to record a programme on BBC Four HD in the early hours of Wednesday morning. When I turned the box on last night, however, I found that the programme *had* recorded! If someone could explain to me how this is possible when the tuner is showing no live information from those channels *at all*, I'd be very grateful.

I'd also appreciate any advice on how to reinstate those channels because as they don't appear in the tv guide I am unable to watch them live or set any new timers.

Update to previous post....

Seems the issue was 4G interferance blocking out random channels. Used a 4G filter and problem has now been solved.
