Is it normal for Lymington not to receive any of the Five channels?
My girlfriend needs her Home & Away fix :/

Stu Seddon: You should be able to receive the full set of Freeview channels. If you have ITV1 and C4 you should also have Channel Five as this is on the same mux, available from all UK TV transmitter sites after DSO, Additionally, if you can receive QVC you should have the remaining Channel Five group channels. Try a manual tune on C27 for D3+4, and C25 for SDN from Rowridge. If you have a non functioning Channel Five in the channel list, do a factory reset to clear the old data before retuning.

I guess the Rowridge engineering works are affecting Film4? It's disappeared off channel 15 and reappeared on channel 810 with a really weak signal.

Snarf: What do you now have stored in position fifteen of the channel list? I would suspect that the inversion effect could have been at work delivering out of area signals, unless an automatic retune took place which coincided with Rowridge being off the air, resulting in an alternative frequency being stored for ArqB.

Can anyone tell me whether it would be possible to broadcast a digital TV channel from the satellite or repeater station on St Boniface Down, Ventnor, Isle of Wight? OFCOM is a bit vague on this.

Hi,
I've lost the COM6 mux completely, I'm in the bh23 area.
itv4 seemed to be choppy and in the last week or so it went completely.
Is it worth doing a swap from horizontal polarization to vertical ?

I live in BN12 6QA with a roof top aerial pointing to Rowridge. I am experiencing occasional picture break up of varying severity on sky sports and other commercial channels through my BT Vision box. I was wondering if I should switch the aerial to vertical polarization or would this cause other problems with interference from France, or possibly the Midhurst Transmitter ? Many Thanks.

If you have a red tipped aerial which is grouped for rowridge, then you should not be getting interference from midhurst, only if you have a black tipped aerial which is wideband, would you receive interference from other transmitters.
Changing to VP for the aerial could cure your problems, however this is not always the case, although you need enough power for the signal to work correctly, you also need the quality of that signal to be good.
As an aerial installer I usually fit aerials now on VP, but have found the odd job that requires HP install.
So I would say give it a try and see if it helps.

Keith: If your aerial is still mounted horizontally then please note that the commercials only transmit on 50Kw on that mode whereas the vertically polarised transmissions are radiating on 200Kw.
By the way Midhurst cannot cause interference to signals from Rowridge as the latter spans channels from 21 - 28 whereas in the case of Midhurst its 50 - 62, and so if you do get interference at any time it has to be from somewhere else or possibly even from continental stations, your reception of commercials being much more susceptible to being interfered with as you are predicted as only being able to receive them with the status of variable even although they are radiating on 200Kw.
