Which companies have run the Channel 3 services in the Sandy Heath transmitter area
Coach: 90% signal is too high. We really need a full postcode (just put into a reply and all the links will come up automatically), but if your getting that with an internal aerial (inside the roof or a portable one?), then your getting a very strong signal (do you have a booster?), since your about 30 miles from the transmitter.
You havn't given a make/model for the TV either - that helps, because some tuners are more sensitive than others. However, just becuase a TV is the same brand, its doesn't mean that the tuner will be exactly the same. And if the signal is slightly too high, remember that the level can slightly change from day to day, something I've found out myself with my HD box.
I suspect an attenuator is a good bet. Really cheap, and just brings the strength down so that there is no breakup. maplin do them, and a variable one kight be fine, and just bring things down so that the TV can cope. have a loom again at the page I linked to.

Coach: Some useful comments from MikeP.
For reception problems encountered by relations at NN1 5BT, I took notes of which channels ran OK, which pixellated/dropped out and which didn't load on re-tune at all.
I put that info into a spreadsheet, and pasted in Briantist's info on which MUX each channel was transmitted in, the frequency (MHz) and power (W).
I'd recommend anyone do that.
In the case of NN1 5BT, when I reordered by wattage, they received everything transmitted at 180,000 W on PSB1/2/3 but everything at lower power had problems.
However COM5 is not that much lower in wattage at 170,000 W.
When I reordered by MHz it became clear there were issues with COM5 on 722.0 MHz suggesting a 4G 800 MHz problem.
Solution: low signal strength, probable 4G interference, masthead booster with 4G filter required.

MikeB: Thanks MikeB. My post code is CB25 0PA and the tv is Samsung. Bought a attenuator and all ok for now. Find it hard to believe i have high signal considering distance and internal aerial. I do have a booster however which acts as a distribution box. Thanks for your assistance. By the way Maplins don't sell too many out of Cambridge shop which suggests strong signal not an issue in the area.

I've noticed a drop in signal power over the last few weeks. All MUXs which used to be about 70/80 power are now down at about 25. The quality is still at 100 and have no problem with the channels but the real issue is that MUX channel 32 which includes BBC4 is now at zero and won't pick up.
Postcode CB22 5DT External aerial on roof/chimney breast. Booster/splitter in loft then leading to a Humax in the living room.
External ground view of aerial seems to be fine. The only idea I have is that we have had some wood fires recently, would this cause an issue with tar coating?
Any other ideas?
