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/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.

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.

It is likely to be due to the hot weather atmospherics. Do NOT retune your equipment, at least not until the cooler weather arrives.

For the passed 2/3 weeks the reception on all ITV station has been very poor and the stations have been unwatchable due to breaking up of the signal. We have purchased a signal booster this has made no difference what so ever. What's going on?
