The symbol shows the location of the Darvel (East Ayrshire, Scotland) transmitter which serves 150,000 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 Darvel (East Ayrshire, Scotland) mast?

david c: Without wishing to go on about it but just to clarify a point I was attempting to make, reception of any signals across an expanse of water can cause them to suffer from considerable levels of multipath reflections, and although in many cases this type of situation can actually be a plus point to the level of signal received, however signals received this way can also be dramatically affected by tide level variations.
RF signals can vary considerably during a 24 hour period, and as previously aforementioned not that noticeable on analogue reception, and although you report having periods of good reception the actual levels involved at the time "might" not be that terribly much above the cut off threshold, albeit what is received being of a reasonably stable nature.
The problem is that non line-of-site installations all rely up to a point on varying elements of reflections, and in your case I feel that its likely the combination of tidal effects coupled to normal minor seasonal atmospheric changes taking place that's the root cause of your problem, needless to say both being totally out of your control.

David C, jb38: Considering that the signal levels from Darvel have increased greatly in the last couple of weeks, I suspect that the nightly variation is causing you to have, overall, too much signal at night.
I realise that sounds like my default answer to everything, but it's not a commonly-understood problem!
If you have a booster or amplifier, remove it or turn it down. If not, or that doesn't help, try adding an attenuator.
Signal levels as reported by your TV or box could be substantially lower than 100%, and yet have too much signal, for two reasons. Firstly, the box's strength meter could be calibrated for test lab conditions rather than real-world conditions. Secondly, some boxes are known to display a low signal level when they actually have a high one. I conjecture that this is because they're reading off the gain setting from the automatic gain control, but the AGC is automatically turned up when it can't decode the signal, so it's assuming lots of gain = low signal.

Mike Dimmick: Yes, and speaking as a long (very) term RF communications service engineer I did consider that factor, although I felt that conditions would have to really be good for that to apply at approximately 34 miles away from a 20Kw transmitter, still one never knows! as signals being received over water can sometimes have the effect as though having been boosted as well as the reverse.
By the way KA27 8AA (Arran post office) used for checking purposes, and so will possibly represent in excess of david c's actual mileage from Darvel.

my 2 freeview tv's have stopped working since the change over, I was on Darvel, I stay in Springburn Glasgow, and Blackhill did not give a good signal.
What can I do to get my freeview working again, Iv'e set up the digital tune but to no avail.
Please help
thanks

why do I not receive the same channels as most of the UK ? I live in Ayrshire and am dissapointed at the meagre amount of channels, as usual for this area we are forgotten about, I pay my TV licence so why do I not get the same as everyone else?
