The symbol shows the location of the Crystal Palace (Greater London, England) transmitter which serves 4,490,000 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.
Are there any planned engineering works or unexpected transmitter faults on the Crystal Palace (Greater London, England) mast?

Technical questions please.
1) When looping the aerial feed through a HDD/DVD recorder to a good quality digibox, does the signal to the digibox get amplified or reduced and by how many dB. I seem to have read somewhere that a + 3 db could occur?.
2) By what % does a 12 dB attenuator reduce the signal . By 90%?
3) With a 2 way passive splitter, is the signal split 50/50 assuming minimal down line coax cable
Tks.

Hi JB38
Thanks for reply.
When on analogue the signal was so poor I fitted a motorised aerial direction box.
At one time it was so bad I had to aim at
Chelmsford, I think, and watch Anglia so unless something remarkable has happened to
improve recption I don't think it can be too strong. My nieghbours at the side and behind
had the same trouble so we seem to be in a dead spot. I took the box back and swopped it
but the new one is the same.Is there any difference between a cheap box and a dearer one.Will try with indoor aerial and let you know
Dave

Hi,
I've lost the band of channels that includes film four, itv 4, yesterday etc. I've tried re-tuning my freeview box but they haven't returned. My signal is from the Crystal Palace transmitted. Can someone help me, in layman's terms, please? I not so good when it comes to technology.
Thanks for any replies,
Pam

David Taylor: Yes, try the set top or wire test, as now you are experiencing the same symptoms with your new box its definitely inclined to suggest instability in the tuner, and that can only really happen when the RF being fed into its tuner is intense to the extent that its causing self oscillation to occur, the audio/visual symptoms you describe being a classic one.
That said though, if it is instability, then what's seen should stop instantly if you pull the aerial out.
By the way, the only boxes that use what could be considered as higher grade tuners are Humax devices, as a huge range of boxes (about 15 or so) seen in places like Argos etc are all based on variations of Vestel (Turkey) chassis, the ironical thing being that its boxes with the more sensitive tuners that are first to suffer from RF overloading, boxes that are on the deaf side generally coping better in this type of situation, that being why some people with more than one box in their house finds that stations can be picked up one box and not the other, all down purely to the differing sensitivities involved.

Pam. Try a manual scan on channel 28 and see what happens.

For pvr's and HD recorders the top brands are humax and Panasonic and it would be wise to stick on these 2 brands only if in doubt as the other brands can be aerial quality /strength specific and may not be suitable at this time under varying condition's

Pam: What's the make and model?
If it's a Grundig GDB2 or GDB3, for example, then I wouldn't expect it to work with these channels from Crystal Palace as there is a known issue.

Pam: Sorry, I meant Goodmans GDB2 and GDB3 rather than Grundig. They both begin with a G!

jb38: My television signal comes from a block of flats across the road, going underground and then fed into the houses opposite!
I have no idea what is there, I just plug the aerial in from a wall socket.
TBH All seems well, but hopefully tomorrow will be the first evening I will be able to check everything since Wednesday.

My admiration increases more and more for guys such as Briantist, jb38, Mike Dimmick and Dave Lindsay. Apart from their technical knowledge, they must have tremendous patience in helping us mortals deal with these switchover issues especially when they have to keep repeating the same answers!
Further to my post yesterday concerning apparent success with my Humax STB and Panasonic PVR, I encountered a few more glitches today. When I retuned the Panny PVR it had lost the HD channels found yesterday. So I bypassed the old booster from the aerial input, retuned again and Robert's your father's brother! Everything is now received, signal strength is around 60 to 70% and quality is 100%, with not a pixel out of place. Previously I had assumed that my signal could not possible be too high as I live near Reading on the western fringes of the reception area (which is why we had the amplifier to get decent analogue reception). I was wrong, since the booster was obviously having an adverse effect. People really close to Crystal Palace must be able to get their signals without an aerial (well almost)!
So thanks guys, your repeated advice on signals being overloaded or too strong have convinced me!
