Two local tv test cards on CH 30 on 791 & 792 in readiness for More Bristol, which I imagine will move to No. 8 when on air.

I had no signal on Tuesday or Wednesday this week at BS6 7JP, but it has now returned without me doing anything! Could you suggest a possible reason please?

Can anyone tell me why some transmitters, like this one, don't carry all the HD channels? I've just bought a Freeview+ HD PVR to replace our Virgin Media Tivo and am disappointed to notice we don't get BBC Four HD.

Ben C: The new HD services, which include BBC Four and BBC News, are essentially pre-switchover and introduced so as to encourage take-up of Freeview HD receivers. The lifespan of these multiplexes is likely to be very short, it being at least 5 years. At that point things are likely to change again, including selling more frequencies off to mobile phone operators.

The equipment used is that which was already in existence, and therefore didn't have to be purchased. The objective is to serve as many as possible.

The only thing you can do is consider whether you might be able to receive from Mendip or perhaps Wenvoe, and pick up the quasi-national HD channels from one of those. With Wenvoe you might be able to combine feeds with your Bristol Kings Western aerial so as to give you West regional ITV and BBC. This option may mean forfeiting of Made in Bristol.

Reception problems using Kings Weston transmitter Bristol.

[ LBS excluded ] As all the multiplexes have a common 200W output why is it that the signal power and quality of COM5 arqA frequency C57 programme signals received at my home noticeably [ generally unwatchable ] less than the other multiplexes? On a Humax box the majority have a comparative Strength of 60%+ and Quality of 100% compared to COM5 Strength of 35% and Quality of 80%

JOHN NASH: Because they're not all received at the same strength!

This depends on the signal path; different frequencies being affected in different ways and to different degrees. The only way that all channels would be received "exactly" the same is if there was nothing around the transmitter: no trees, no buildings, no ground, no air, no people. This is physics: as soon as you introduce objects you introduce things that can affect signals and as objects affect different frequencies differently then they may be received differently.

StevensOnln1: Hi - I am experiencing serious dropout on the PSB1/BBCA Mux from the Bristol KingsWeston transmitter.

Wierd thing is that this is in the middle of the Mux frequencies and I don't have problems with the lower & higher frequencies. In fact the lowest frequency is apparently output at 20W but I have a signal strength of 69% but the BBC Mux outputs at 200W but I only have a signal strength of
48%

These are the signal strength readings I am currently seeing

Mux , Channel, MHz, Power, Strength, Quality
LBS, 30, 546.0, 20W, 69%, 100%
PSB2/D3+4, 40, 626.0, 200W, 70%, 100%
PSB1/BBCA, 43, 650.0, 200W, 48%, 100%
PSB3/BBCB, 46, 674.0, 200W, 66%, 100%
C0M4/SDN, 53, 730.0, 200W, 70%, 100%
COM5/ArqA, 57, 762.0, 200W, 50%, 100%
C0M6/ArqB, 60, 785.8, 200W, 55%, 100%

Seems to be weather related, with the big rain-storms we had over the past few days ???

PSB1 is now registering strength of 53% which my receiver seems able to cope with. Not brilliant (Aerial is in the loft, so possibly this degrades the signal) but no breakup of signal so happy again

PSB1/BBCA, 43, 650.0, 200W, 53%, 100%

Geoff Gaunt: Check your system - a frayed wire etc could be the cause of that mux being low (it doesn't always follow that the weakest mux goes first). And the fact that you had lots of rain when the problem occured points to a possible problem with moisture in the system. Even in a loft, rain can get in, etc.

Thanks Mike - cable is fairly new and double-screened (ie copper braid + foil) satellite cable - all internal so has never been exposed to the weather.

This has happened once before - same issue for a couple of days with the SD-BBC channels on PSB1, and that was during a period of extreme weather.

I appreciate that there could be signal attenuation due to the roof, but according to Loft and indoor aerial installations for TV, FM and DAB the attenuation is higher the higher the frequency, so it's strange that the lower freq. PSB1 @ 650MHz is worse than COM4 @ 730MHz

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
