Off the mendip transmitter trying to watch on freeview ch 24 the tour de france but have continual picture/audio breakup - assume this to be [i] atmospheric & [ii] low power tramsmission - nothing can be done about [i] but hopefully this will improve when full power transmission begins next year!!!

Bath repeater is not transmitting freeview ch24 amongst others are there plans for repeaters to become fully functional or will user in this and similar areas always be the poor relations?

Freeview reception in clevedon, Somerset.

in recent weeks picture on channels 10, 12, 14 has been at times unwatchable - picture breaking up. other channels are usually OK. have three aerials, one recently installed for digital changeover on roof, others in loft. same problems on all three aerials. some neighbours have similar problems.

are there issues with low power on mendip transmitter and some receivers ?

I have at last solved the problems tuning my Panasonic HDD Recorder. After months of frustration i finally got around to retuning the HDD via the aerial feed in my bedroom, which runs off of a seperate aerial and lead. The HDD tuned in perfectly. I re-connected the HDD downstairs and again had very bad reception/loss of signal. It wasn't until i wiggled the aerial coax input that i found the picture got bad then better. To cut a long story short, i cut about a foot off of my lead, attached a new coax plug and hey presto all channels are now tuned and functioning correctly. Thanks for all your advice!

The BBC multiplex (62) on Mendip has suddenly started breaking up for me, and judging by the variations in signal strength and signal qality mI am seeing, it is co-channel interference from a distant station.

Can anyone help by pointing me to a schedule which lists the dates of each of the changeovers and the channels on which the main transmitters transmit? I could then track down what might be the intefering station.

I could do it the long way (enterring postcodes appropriate to each main transmitter in the postcode checker) but I would have expected there was a listing somewhere.

Sorry for the typo.
"The BBC multiplex (62) on Mendip" should of course be "The BBC multiplex (61) on Mendip"

I have discovered your link Transmitters has Find Freeview by frequency, and when I enter 61, I get shown all the transmitters transmitting on 61, and their (planned? actual?) changeopver dates.

The Workington relay in Scotland started transmitting its BBC multiplex on C61 on 22 July 2011, so it could be a candidate for causing the inteference with my Mendip signal.

But it broadcasts on only 10Watts. Is it feasible that a 10W signal from Scotland could cause co-channel inteference with a 100kWatt signal from Mendip? I normally receive Mendip 61 at 60% strength and 100% quality but I am now seeing it drop to as low as 40% strength and 10% quality.
All other Mendip multiplexes are OK so it is unlikely it is my aerial etc.

There is no transmitter work reported on Mendip.

Any thoughts will be appreciated!
