The symbol shows the location of the BlaenPlwyf (Ceredigion, Wales) transmitter which serves 17,000 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 BlaenPlwyf (Ceredigion, Wales) mast?

Sorry to be cynical but I do not think we are being told the truth. The signal strength from Baenplwyf is definitely down but we are told there is no engineering work! I believe that to improve the capability of freeview this is being achieved by reducing the power level of signals. No promblem with ITV and S4C but BBC &SKY channels a waste of time. Don't blame aerials or weather you'll be like BR

Funny or not funny! The power at Blaenplwyf has gone up after my message and all channels are there without Pixellation. (BR) British Rail and leaves on the track syndrome. Freeview you have a long way to go but be honest with TV public!

Mr Edwards: This is a SELF HELP website with volunteers who put their own time in to help people. The broadcasters do not routinely monitor this website (as far as we know). If you are currently having a problem and you think it's down to transmission (though usually it isn't), contact the broadcasters. There's a list of contact numbers etc at Broadcaster complaints details | ukfree.tv - independent free digital TV advice .
The BBC track fault reports, but mostly they and the other broadcasters rely on telemetry from the transmitters. If the fault occurs anywhere before the transmitting antenna, on a major station, they know about it and, if it affects the BBC, it should be recorded at BBC - Reception problems . This site scrapes that BBC site periodically and puts the result here as a 'Transmitter Engineering' post.
Signal levels do vary with weather conditions - just as you get red skies with dust in the atmosphere and 'heat haze', limited visibility due to fog and rain, and indeed even mirages. These are all changes to the way electromagnetic waves travel - radio and TV have much longer wavelengths than light but many of the principles are the same. Digital UK's predictor takes account of the expected variation and still reckons that better than 90% of locations in your grid square should have reliable reception for more than 99% of the time (for some services, the prediction is ALL locations in the square). That prediction is based on a good quality high-gain aerial and a fairly short downlead (cabling).
Given that, I think it's likely that it's been raining and that water has got into your aerial system. That makes it much harder for the signals to travel down the cables (coaxial cables at high frequencies are waveguides with the signal travelling on the surface of the conductors, it's very different from power cables). The improvement is likely because it's dried out. Different frequencies are affected by different amounts - usually the highest frequencies are worst affected.
You should check that any connection boxes are mounted so that the lid is facing downward, to avoid water getting in and ensure that any water that does get in can drain out. You should also check that all cables are properly secured, so they cannot rub against roof tiles or brickwork, and check that the insulation is fully intact. Also check that the cable insulation is still flexible: the insulation is damaged by UV light and eventually becomes brittle and porous, again allowing water to get in.

Dear Mike,
I no longer have a problem (Post 2 refers). As if by magic it was corrected after my first post but recieved a Email from the BBC later apologizing for my problems. Thanks for time.
