over the last few days we have regularly lost ALL multiplexes on all tvs on all aerials. This is doubtless due to the Dutchmen who have been blotting out Sudbury for decades. Do those who constantly advertize the 'benefits' of freeview not take this on board?

nick: Hi, Nick. The main advantage of Freeview is that it is less expensive and easier than the other options for watching live television. The number of channels on offer is acceptable to the majority of tv viewers in the UK. The Freeview transmitter network as well as the Freeview digital tv systems in use were both planned as carefully as possible so as to minimise the effects of tropospheric scatter, 'lift', atmospheric or European interference, whatever you want to call it, so, 'Yes', the proponents of Freeview did take this on board! Out of interest, two questions for you for starters: (1). How far are you from the Sudbury transmitter? ( Your postcode would be a bonus) and (2). What is your Freeview equipment? i.e. is it a cheap or more expensive setup? The cheapest Freeview boxes have a poor reputation because they use poor quality electronic components, resulting in poor performance, poor signal sensitivity and poor signal quality. Assuming you've read this post. I'd appreciate your reply to ascertain whether we can advise you further. Richard, Norwich, Thurs. 9th. June, 2016 at 09:20 a.m.

Paul: Hi, Paul. Quoting from the official Digital UK website, "Latest News: Viewers in some parts of the UK may experience temporary disruption to their TV signal today due to high atmospheric pressure. We advise that you do not retune - reception will return to normal once this weather system passes." Should have passed us by by Saturday, all being well! Richard, Norwich.

Hi Richard,
Humax! But have cheaper ones which are no worse.
IP15 5HF
Use Sudbury with super aerial as local xmitter is 'light.'
Near 100% signal/quality, all muxes, but gets knocked out entirely at the slightest cause, Dutchmen, rain, fog.
Not impressed, used to get interference on analogue, but never 'no signal.'

nick: Maybe you are one of those who simply gets 'too much' signal, which can cause freeze-ups due to overloading! 85% is the max signal strength recommended for HD. Richard, Norwich.

thanks, Richard, but would think if that were so it would be all the time, whereas my problem is weather related, and the signal and quality drop to zero.

nick: Having too much signal can cause the tuner to become overloaded and appear to have no signal. If you are seeing 100% during normal conditions then you already have the maximum amount of signal the tuner can handle. Try fitting an attenuator such as one from the link below to reduce the amount of signal reaching the tuner. There are also 6db, 9db and 12db versions which can be connected together in any combination to reduce the signal further if required. I have a 3db connected to my main TV which has successfully stopped breakup I was experiencing on some of the HD channels.
