Den: Could you get Freeview before switchover?
I see that the Bembridge area is quite well served by the Brading relay transmitter which does not carry the Commercial channels such as Yesterday. I wonder if this is a general indication of difficulty receiving directly from Rowridge in some parts of that area.

g.baseley: This could be caused by you receiving a signal at a level that's verging on being excessively powerful, so if you use any form of booster then it has to be by-passed, if though you do not use a booster then for a test try using a set top aerial, giving an update on results.

I would like to concur with MJ I have lost all freeview hd channels and when I try a manual retune of channel 21 it shows a very low to nothing signal strength and the same again for quality, every other station/channel is fine. Used to have 94 stations now 89. Location Portsmouth

What is the reasoning behind this transmitter broadcasting on two polarities? If people have reception problems, can they have two aerials at different polarities to give a super signal?
Is this an experiment, for other transmitters to follow?
What effect would you get putting the aerial on the slant? Best of both worlds?

Ray H: If you are referring to Rowridges HD service on channel 21 then as I have also said to g.baseley you will have to try a test by reducing the signal level received as HD will always cut off before SD if the signal received is excessively powerful and giving exactly the type of signal indications as you have mentioned, as the signal blocks the tuner and that why it either indicates low or nothing at all.

jb38 I appreciate your reply and advice, just went to remove amp, checked signal strength and quality on 21 and both on 90% with amp still connected and have retuned all hd, I am now puzzled!

Ray H: Well one very possible reason springs to mind, being that when you had previously made the check the normally occurring variations in signal strength that occurs most of the time dependant on time of day as well as weather conditions, had allowed the signal to be just that tad stronger to the point that it was partially blocking the tuner, whereas when checked the second time it had dropped just enough to allow the tuner to operate as normal, as the difference in levels between these two situations occurring is very small.
This is a peculiar effect associated with digital reception that mystifies many, as if a persons reception is being blocked because of an excessive level of signal and they fit a variable attenuator, its generally always found that if the attenuator is fully in operation (max attenuation) then the signal is OK at maybe about 70 or 80%, but if they slowly advance (kill) the attenuation and observe the signal strength / quality rising until the max indication of 10 (or 100%) and is not stopped at that level, then any further advancing will result in the signal suddenly crashing and accompanied by low strength and zero quality reading being seen again.
