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.

Is the transmitter output the same in all directions?

Bruce Manning: If you provide a full postcode I can advise. Also, you can also fit Freesat, where you can watch ALL of the BBC regions. Which BBC regions are on satellite? | ukfree.tv - independent free digital TV advice .

Hi Briantist my postcode is GL19 3JS (Redmarley, Glos).

Bruce Manning: Whilst you CAN currently move your aerial to Mendip, the service from there will, due to changes elsewhere in the network as part of switchover, deteriorate over the next few years.
You do, however, get the ITV1 West service from Ridge Hill. It's probably on channel 803 on your box.

Bruce Manning: The DUK predictor is showing poorer performance on Mendip PSB muxes from August, because they use the same channel as Waltham's will when it switches over.
I would think your aerial is likely to have better directional properties than the model used for the calculations, so you could certainly try it and see.
The aerial would need to be aimed fairly accurately, as the Carmel transmitter in south-west Wales also uses these frequencies.

Thanks Briantist and Mike Dimmick for your help - I'll give it a blast. The aerial was upgraded approx. 2006 to cope with Freeview. Channel 802 seems to be another ITV option though haven't had a chance to watch it long enough yet to catch the local news/weather (to see if it is West).

Does Ridge Hill transmitter give HD channels?

It's very frustrating: after years of snowy anogue and a handful of digital channels at this admittedly marginal postcode for Ridge Hill, HR8 1RR, on 20th April we had a full suite of digital channels, but on 28th April, we started to lose them and now don't have BBC1, 2, 3 or 4 any more, for example. Is this the inversion layer effect in action (although I thought it didn't affect digital)? I am pretty sure that on 20th April some RH muxs were at 20000 watts and the rest at 15000: now the ones that aren't at 20000 are only at 10000. Are they fiddling about to.see if anyone complains, and if do, how do I complain? Thanks for any advice. John

John Haigh: Atmospheric propogation affects all radio signals. Actually, if there is another digital signal on the same channel, it has a greater effect than analogue signals with a higher quoted power. A lot of the power of an analogue signal is wasted in the carrier, which only knocks out a small portion of a digital signal.
Your fundamental problem is that the hill to your west blocks line-of-sight to the Ridge Hill transmitter, which means that you have a much lower signal level than you otherwise would. Inversion affects are likely to increase the signal levels received from Ridge Hill at night, but also increase distant interference.
It's possible that the signal levels were good due to the high pressure around the 20th, and they've now dropped back to normal, insufficient, levels. The prediction is still for a good chance of getting a reliable service, at least at the moment, so you may want to get some professional advice as to why it's not working.
Because you're relying on indirect reception, your results are likely to be affected when Rowridge switches over next year - it will use the same channels as Ridge Hill for all services. Obviously, as it's beyond the horizon, this will depend heavily on weather conditions.
The maximum permitted signal level for the commercial multiplexes is 10 kW and has always been 10 kW in Ofcom documentation, at least since the commercial multiplexes were put in-group. (I have a document from 2007 that shows them at different channels.).

I appreciate your trouble in explaining all this, Mike.
It looks like I was fooled by the weather into thinking things had been improved by the switchover, when in fact they are substantially worse for us. At least we had all the BBC services before, one way or another, whereas we now only have access to the two HD channels on appropriate equipment. Ironic when you look at where the licence fee goes.
I obviously don't understand what you mean by "commercial multiplexes" as the RH mux which carries ITV1 etc is shown above as being at 20Kw. Not that this is a clear factor in my problem, as the BBC mux is at 20Kw also.
Yes there is a (heavily wooded) hill between my house and the transmitter. I am told I have the best antenna possible, but I am going to look into having it raised higher, though no doubt there will be a good reason why not.
It seems I am going to stay frustrated, then.
Thanks again for your help.
John
