Jack Owens: Hi, Jack. If it's channel 59, the most likely issue is 4G interference. Do you have a 4G filter fitted? A filter is free from at800, the organisation set up to make sure viewers who rely only on Freeview for TV continue to receive it when 4G services arrive in their area. Its web address is:-

at800 | 4G & Freeview | 4G interference | 4G Filters | 800 MHz

Hope this may help, Richard, Norwich.

Hi Mike, Thanks for your response, actually the problem is with the channels on the Com 5 group above, ie PICK,Dave, Sky News etc but I guess the suggested solution should apply equally to this group so I'll check out cabling and leads further. What I don't fully understand is why this particular group should suffer poor reception if all other aspects are equal with other COM groups especially if the transmitting power is the same. Rather odd that Dave cannot be received but Dave ja vu on the other COM can! Have to watch Dave an hour after everyone else! Don't know much about technical aspects but is it possible that transmissions are "spread" and a physical barrier ie a tree, could block only one COM's channels?
Thanks for your comment and I'll look at the aeria
lead etc again

Hi Richard, thanks for your comment. I have checked with the 4G people at the 800 site and they confirmed that 4g interference at my location is not an issue but they were helpful in pointing me back to this site for further investigation.
Cheers Jack

Jack Owens: Hi again, Jack. I'm sorry that it wasn't as simple as a 4G issue! Looks like it's back to the suggestions made by Mike B. Remember that something as simple as a small group of frayed strands of wire in the braiding of the outer copper of the aerial lead or fly-lead can prevent just one multiplex from being received properly! Good Luck! Richard, Norwich. PS High pressure could be the other option, which means waiting a day or so for it to lower!

Jack Owens:

When signals are affected by temparature inversions, such as could be prevalent currently in some areas of the UK, the effects vary dependant on the frequncies of the signals. The COMs are transmitted on different frequencies, as shown at the top of this page, so some are more likely to suffer than others - hence the selective effect on programmes. There is no way of predicting what signals are likely to be affected and it can vary throughout the day too.

Richard Cooper:
Richard/Mike, I hardly dare to believe it but having taken your advice and after deleting all stations on my Humax box and re tuning on automatic search, all the previously unusable stations now seem to be watchable.
Your advice re the cabling seems to be the answer after months of frustration. Having previously only done a cursory inspection of cabling, I took the co axial plug off the lead and ruffled up the screen wire on the cable and tightened and replaced the plug and hey presto, new channels from the previously errant MUX!.
However, The weather conditions today are very Muggy and I only hope that it's not just freak atmospheric conditions that are allowing only a temporary respite!
The stations captured appear to be from a variety of transmitters : London / Oxford and Sandy Heath which does not matter - BBC and ITV now have alternative news channels to select.
So, steady as she goes and I will report back if things are proved to be only temporary.
Meantime, thanks for your advice - very much appreciated.

Hi Mike, I took the liberty to combine an answer to You and Richard Cooper on the same reply which I posted earlier this evening.
Thanks again.

Jack Owens: Glad it seemed to work. Its always worth swapping out the old coax lead - they are really cheap, even for a decently shielded one, and it can sometimes make a surprising difference.
