Richard:

It might depend on which log periodic you have, but they all tend to have slightly less gain at the lower end of the band. You might just be too far away, check the predicted reception putting your postcode into http://www.digitaluk.co.uk/coveragechecker/main/index/dummy/NA/yes

It's always worth checking that you don't have any extra loss in your system due to cable or connection deterioration, unplug your coax plugs, check all connections are clean and reconnect.

Channel 64 from Mendip is all over the place. Signal strength and quality is wavering between 10 and 6 with periods of block interference. All other channels solid at 10. Address BS22 area. Any ideas...

Alan Alder:

Your partial post code is insufficient for us to find out what the expected reception is like at your location, only a full post code is accepted by the Digital UK Coverage Checker.

As I use Mendip, I have checked all my channels and there are no problems at all. Freesports on LCN 64 is fine.

So you may have too much signal, indicated by all other channels showing a strength of 10, or else you have a poor connection in your aerial cables that is affecting just one frequency - it does happen. So please check all your aerial connections and ensure that your signal strength is between 60% and 85% on all multiplexes.

Ch.64 is on the COM8 mux, see http://www.digitaluk.co.uk/channels/channel_listings
Check to see is you are having similar problems with any other channels on the COM8 mux. If so, you may be suffering a touch of interference from Wenvoe.
Also check that your aerial is still intact and hasn't moved in the recent high winds.
