: SDN remains on - until 27th at 2kW (according to DUK).

It has never used + which is what used before and up to 27th. The other five muxes are a SFN with TW now. SDN's SFN doesn't start until 27th.

Thanks Dave, am using Promax 4C on here. Would I expect to see Ch48 about 10dB down on other mux's?
Absolutely nothing on Ch48, just noise floor :-(

All seemed to be up and running OK this morning.
There were a couple of apparent momentary dropouts on D3&4 just before lunch.
SDN is OK on Ch48.

Tony: Yes, -10dB is the difference.

Micky: This is an independent site, thus information listed is sourced from elsewhere. Mistakes can happen and I have pointed this out to who is the site's owner.

One of the problems you may have is that and are high and therefore strong signals, and relatively speaking, in the middle is weak. This marked difference could be the source of the problem as the high power signals could be acting to desensitise your . That is it is "looking" at 48 with high power signals on adjacent .

This could be likened to your eyes densitising at night when bright light is shone in your direction. Car headlights coming towards you, for example, may reduce your ability to see the surroundings.

You "may" be able to reduce the level of all signals by using an attenuator inline with your aerial lead in order to increase the sensitivity of the receiver. I say "may" because in so doing you will be reducing C48, but at 2kW at only four or five miles away is still powerful so you may be able to find a sweet spot where it all works.

If you get a variable one (20dB) you can then adjust it whilst viewing the strength on C48. Give it a few seconds to adjust to any change you make. Then find where it is at its maximum.

Attenuators can be picked up from online sources such as eBay or Amazon for £3 or £4.

Micky: Generally speaking, most people shouldn't need a at such close proximity to the . I say generally speaking because I don't know whether there are local obstructions.

This was true before when a set-top may well have been sensitive enough at your location.

The main reason I would expect you to be using a booster is so as to distribute the signal to different outlets, although even then you may well have sufficient signal to split it.

As a matter of principle, I suggest that you only use a booster if it doesn't work without it and not the other way around. With digital , too high a signal level gives the same sort of effect as too little signal. That is the signal strength gets lower and when it is really high, the becomes overwhelmed and shows "".

So long as the is good at all times (no break-up) then you have the best you can get. If the strength is at 75% (for example) with good quality, then there is nothing to be from trying to push for 100% strength; only quality to be lost.

I'm not familiar with the Humaxes but I do know that some receivers have in-built boosters. Make sure that this is set to off.

If, having removed the booster, you find that is still unavailable, then the solution "may" be attenuation, as I suggested above.

A set-top aerial should pick up less signal than your -top or fixed aerial (if you're using one). Or try a piece of wire about 12 to 18 inches long inserted into the inner part of the aerial socket. These may be temporary fixes to restore Quest etc until 27th, if nothing better can be found.
