I continually have problems with BBC4 HD reception from Rowridge, presumably because COM7 is broadcast at half the power of other channels. It seems pointless for BBC to take great care with the production values of wildlife films and dramas and then compromise at the transmitter.

R Murchie: The BBC don't decide the transmitter power levels, the maximum levels are set by Ofcom and has to be lower for COM7 & COM8 on most transmitters because the same frequencies are being reused more than the frequencies of PSB1-3 & COM4-6 so using higher power levels would cause more interference and reduce the number of households who can receive COM7&8.

Haven't checked here for a while, but looking now at the channel list, it appears that Rowridge VP Com mux have been reduced in power from 200,000W to only 50,000W.

Is this a mistake?
I use VP as all the mux were originally 200,000W, which is why I use it. I only came to check on a mux today that was giving me some low quality problems last night, so if there has been a reduction in power, then that might be why.

Surely having VP the same power as HP on the Com mux is pointless and goes against the reason we got VP in the first place.

Mike T: There have been now power reductions at any transmitters (other than temporarily due to faults or engineering work) so it appears that an error has crept in to the data for Rowridge VP somewhere.

I thought as much Steven, as the whole point of VP was to give us full power on all 6 muxes. Hopefully Brian will rectify the mistake.
Cheers.

R Murchie: We also have the same problems in the outer reaches of Rowridge coverage in Dorset - BBC4 HD present sometimes and then not. Fortunately we only use Freeview as a reserve with the great majority of our viewing by satellite using either a Manhattan HD Freesat box or our Technomate HD generic receiver fed from a second motorised dish. Also, interestingly and not really anticipated by me, our broadband streaming activity is steadily increasing.

Tony Hill: Understood, but I find that Freesat is subject to adverse weather conditions, and the BBC iPlayer picture does not really compare with an HD broadcast. I will see what Ofcom have to say about disadvantaging a PBS broadcaster that we have to pay for.

R Murchie:

If your satellite reception is seriously affected by weather then you either have the wrong size dish (too small) or an alignment fault. The oft fitted 35 cm dish is far too small for most parts of the UK in my extensive experience. The smallest for your area should be at least a 50 cm or maybe a 60 cm one. (I use a 60 cm in Trowbridge and have no weather problems.) So with a decent size dish your Freesat reception should be very good and uninterrupted unless we have a blizzard of polar proportions!

Your TV licence is to allow you to operate TV receiving equipment to watch live broadcasts or catch-up on the BBC iPlayer. So Ofcom will probably not respond to your suggested enquiry.

MikeP: And to add that since Iplayer is at 720p and HD broadcast is at 1080i, if you take into account the sets own upscaling, there shouldn't be a vast amount of difference between the two, at least after a minute or two.

OK I have thatched property so each time I have the thatcher in I have a new aerial. 38km from Rowridge 160 degrees

The new aerial is VP old HP I have lost signals cannot easily receive e.g.Vintage TV.

From your correspondence it would seem I need to go back to HP

What do you think
