Which companies have run the Channel 3 services in the Sudbury transmitter area
I have made what I think is an interesting discovery today testing several aerials at only 6ft from the ground. They all have good reception but they ALL are very poor with regard to signal quality, 33%, on channel 37, right in the middle of the range of channels used by Sudbury. This is presumably why 37 is the first to go on my rooftop aerial. if 47 were poor, or 29 were poor, I could understand it was an aerial problem, but this is a mystery. Any ideas please?

Hi there. I assume you are obviously pointing them at Sudbury.
1) Try a different spot and see if the Quality figure gets better or worse. If it gets worse, you may possibly be getting near some source of interference
2) Try rotating the aerial to different compass bearings and see if you can identify/receive and other signal on C37. You may have to move tyo another spot if buildings get in the way.
3) Try all the above with the aerial polarisation vertical
4) Try with different "in between" polarisations.
Obviously with a number of those, I'd expect the Sudbury signal to reduce in both Strength and Quality, but there may be cases where there's little drop in Signal but significant drop in Quality.
There will be points where the Quality is sufficiently low, the Signal will become zero (it's become just noise or possibly interference).

Chris SE, thanks. I follow your reasoning here. This must be some form of interference, and I suspect from your notes, that it must be that Holland has a troublesome transmitter on this channel.
It is almost impossible to locate my test aerials elsewhere, but I have made further discoveries. Signal quality on 37 improves after dark.
Some of my aerials, during the day, show the quality jumps up from 30 to 90, but then within a second jumps back down..
I have tested several aerials, and the log is second best. The only one that defeats this problem during the day is home made and produces a steady 70 plus quality. Basically it is the old fashioned 18 element group B, but with two parallel groups of 16 directors and a circular dipole about 8 ins diameter. which markedly improves the bandwidth. The directivity may be keeping out the intruder.

Interesting, but I'm not sure I'd jump to the conclusion that it's Holland at present.
Two things of particular interest about the Quality figures.
1) the brief jump to 90% - does this occur at regular/particular times of day or is it totally random?
2) You mention it improves after dark, by how much, what figures? (This may be related to a bit of temperature inversion of course).
