The symbol shows the location of the Bromsgrove (Worcestershire, England) transmitter which serves 30,000 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 at Hollywood and receive Dig Tv (Freeview) via a 'Communual Ae distribution system. Reception on most channels is 'satisfactory' but suffers ocassional 'sound drop out'. Some channels 'freeze'.'Yesterday Ch 12,disappears completely.
Q... Do all channels eminate from the same Transmitter 'site'?
Thank you

Peter Short: Normally I'd say yes, everything comes from the same site, but in this area three transmitters - The Wrekin, Lark Stoke and Bromsgrove - operate as a so-called Single Frequency Network. Or, at least, the public service multiplexes all do currently. The commercial multiplexes will do from September, but the allocated channels are currently in use at Sutton Coldfield so for now, the signals from Bromsgrove remain on pre-switchover channels and reduced power levels.
A SFN uses the same frequencies at multiple transmitters, and your TV receives a contribution from each of them. The transmission from each transmitter is carefully timed so that the signals are approximately coincident, where they would be strong enough to interfere otherwise.
The power levels at the top of the page, against the channels on each multiplex, show the final situation. Actually, Mux C is still broadcasting at 50W on C34 (inherited Mux 1's configuration) and Mux D/ArqB at 25W on C29, at least according to Ofcom.
If the PSB signal levels are on the high side, you could be suffering from intermodulation, which causes frequency-shifted copies of the signals to be added, causing errors. The transmission contains error-correcting information but there's a limited amount of error that can be corrected - once this amount is exceeded, the picture starts to break up. The copies closest to the original signal are strongest so tend to affect adjacent channels worse. The ArqB mux is adjacent to the new HD mux.
You could ask your landlord or agent to see if it's possible to adjust the levels, to ensure that they're neither too low nor too high. Still, you may have to wait for September.

I live in Droitwich and have had my aerial re-orientated to the Bromsgrove transmitter. I have a Humax PVR box and LG 32" SD TV that pick up all the freeview Channels from Bromsgrove without problems. However MY LG Freeview 32" HD TV is not showing the channels on the Dave MUX. It tunes the channels when I do an Automatic scan. It also tunes in fine when I do a manual scan on CH29 it shows a strength of 60 and a Quality of 100. I can then view all the channels on that MUX but as soon as I view a channel on a different MUX and then try to return to Dave, sky news etc I get the no signal message. When I check CH29 under the Signal test menu it shows Zero Strength Zero Quality. I have moved the TV to a diffent room and even to a different house! Is there something 'special' about that MUX that could be confusing the TV or is it likely to be a fault on my TV? I do pick up some duplicate channels on CH 21, 24 and 25 but I have done manual tune to try to rule out interference from these. Thanks Richard.

Richard Evans: Some TVs or boxes can get confused if they're retuned from one site to another. It might be necessary to do a full reset/factory default/first-time installation on the TV.
If you get really stuck, try doing a full reset with the aerial unplugged, in order to delete all channels, then manually tune the frequencies you actually want.
Do also be aware that the Humax PVR9200T has an RF output, that is, it puts the currently-tuned picture and sound on the RF cable going to the TV, as if it was an analogue TV station. Check that this doesn't clash directly with any multiplex you want to use, isn't immediately above or below one, and that it isn't 5 or 9 channels away either.
My PVR-9200T seems to create a lot of noise on and around C36 no matter what I set the RF output channel to, when it's in standby.
The Humax also has a small amount of gain and noise, so if reception is slightly marginal, you may find that it works better or worse when the box is in standby.
There will be a retune at Bromsgrove on 28 September, which will move the COM muxes to their final channels and power levels.

Mike Dimmick: Thanks for the reply. The Humax is attached to an old CRT and is behaving itself! I have tried the full reset on my troublesome LG 32LD490 but the problem persists. I am starting to think it must be a TV problem. Whats confusing is that the TV will tune to and show me the channels on the Ch29 MUX its only when I view another MUX and then return that it gives the no signal error.

I live in Droitwich and my aerial receives all freeview channels except the HD ones. My TV set is a Toshiba 32BV700B 32 Inch Full HD 1080p Digital LCD TV but it simply will not pick up the HD. Any suggestions?

Thanks Briantist. When I bought this TV set I was told that I wouldn't need another box and that it would automatically tune to all available HD channels as it was "Full HD" rather than just "HD ready". The manufacturer's brochure also claimed that as well, so I'm very confused... I suppose I'll just have to get another one that does what it's supposed to. What should I ask for to make sure it will get HD?
