The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 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.

I live in North Dorset where the strongest signals are from the Mendip transmitter. We are shadowed by hills from the Winterborne Stickland transmitter.
We can however receive from Rowridge down the Stour valley, but ITV stations are only occasionally available on freeview. Having read this site, I think I understand that only BBC channels are currently transmitted at full beans from Rowridge, which would account for this. Will the ITV channels' signal strength be boosted after switchover in March 2012?

Whiskeymac: All multiplexes from Rowridge currently broadcast at the same power level, although multiplexes 2 and A use a different mode that requires greater signal quality for reliable reception. Mux 2 carries ITV1, ITV1 +1 and ITV2, while A carries ITV3, ITV2 +1 and CITV. ITV4 is on Mux D.
Mux 1 got the best frequency allocation, then 2, A, B, C and D, but due to the mode differences, B C and D can sometimes be better than 2 and A.
On 7 March 2012, Mux 1 and BBC Two analogue close down, and high-power BBC A starts at 10x current power level.
On 21 March 2012, Mux 2 and B and the remaining analogue channels close down. High-power D3&4 (replacing Mux 2) and BBC B/HD (replacing Mux B) start up at 10x current power level.
Because the allocated channels clash with various relays in London, the commercial multiplexes cannot go full power until 18 April 2012.
Rowridge will transmit on both horizontal and vertical polarization - for aerials oriented horizontally (elements going side-to-side) and vertically (elements going up-and-down). On horizontal polarization, the polarization used currently, the PSB multiplexes will be full power but the COM multiplexes will only be one-quarter of that power (50 kW). On the new vertical polarization, COM power levels will be the same as PSB power levels, both 200 kW.
Digital UK predict that your reception of Mendip should be better than that from Rowridge, even with a vertically-polarized aerial. Rowridge COM multiplexes will be poor, both on VP but especially HP, because Stockland Hill has been assigned the same frequencies for its COM multiplexes.

Hi
I live in southampton city centre and my digital reception for mux 2 channels are getting worse and worse, either cutting out or freezing. With the signal being made stronger in 2012 would this be improved, or could it be an issue with the aerial? I had no problems until early last year, but they are now impossible to watch, non mux2 channels are all perfect

Thanks Mike for that very comprehensive reply.
This sounds like very good news as I use a vertically orientated antenna pointed at Rowridge. We are 50/50 around here, choosing according to what local news seems more relevant. BBC South and Meridian cover our area and all points East and South. West of here there is no crime and news consists of how well the cider apples are growing!
I don't see Stockland Hill as a problem as we have the ridge line of the Wessex Way immediately behind us which is a total barrier to transmissions from that direction.
So I will look forward to 10x current power output all round which should sort out my Freeview reception at a stroke.

I live in Brighton BN1 and yesterday had a full complement of Freeview channels. Today i could not access most of the Digital and Analogue channels available yesterday.
i retuned my TV and now can only access 1 Analogue channel and 10 Digital channels.
Does anyone know if there are transmitter problems or advise me what I can do to regain the normal service?
