Freeview Light on the Newhaven (East Sussex, England) transmitter

H. Gravett: Which is the directed to?

Have you been able to receive on the main TV before last Wednesday?

Have you tried taking the two TVs to the main room and tuning them in?

Which have and have not been picked up? In particular, I ask the question in relation to BBC One, ITV1, , TV and .

Are there any channels numbered from 800 onwards?

H. Gravett: In answer to your question of why some receivers may up some and not others are:

- differing sensitivities of the tuners, particularly affected where signals are near borderline.

- differing leads from the point of distribution.

Do these totals include radio channels as well as TV ones?

I would be more concerned with whether you are receiving all channels that are being broadcast by the to which the faces. You've said that they all use the same aerial, so where is it pointing? Is it to the transmitter which is at 134 degrees with the aerial vertical? Or maybe it's at 37 degrees with the aerial horizontal?

With any, you should certainly be receiving all BBC definition TV and radio channels as they are now on full ; i.e. they have "switched".

For a full list of post- , see here:

DMOL Post-DSO Multiplex Channel Allocations

You should have all those in the PSB1 (BBC) table where there is a bullet in the "E" (England) column.

Thanks , I think you may have answered my issue. Although the points to , one of the TV's is using a higher grade . Just done another re-tune, and it's back to 11 TV & 11 Radio on CH50. I think it was then picking up CH 25 & CH 27/8 as well at the time.
However, do I need to all the coax cable to receive all on all TV's, as main TV only seeing 7 TV & 11 radio. I'm only 2 miles from NH & is visible. Will NH be the best transmitter to use once 13th comes?

H. Gravett: Whilst will probably be your best from a strength point of view, it will not provide the full range of as it will only carry Public Service Broadcaster (PSB) multiplexes.

Refer to DMOL Post-DSO Multiplex Channel Allocations for the three PSB multiplexes ("muxes"). The Commercial muxes, known as the COMs, are only broadcast from the bigger transmitters. The COMs are shown below the PSBs on that page.

For this reason, you will probably wish to attempt from a transmitter that carries the COMs. You "may" find that the needs to be outside above level in order get enough signal from one of these other transmitters. There is probably little to be lost by experimenting in the .

I think that will probably be the first one to try. As Newhaven is a of Heathfield, you will get the same regional programming.

If your neighbour's property adjoins yours in the direction of Heathfield, then this will probably rule out reception in the loft. That is, if the aerial is to be pointed through your neighbour's loft space, then I think that there is little of success.

If your Newhaven aerial is a Group B one, Heathfield is Group B as well (or it will be once has completed). For Heathfield you will need to switch the aerial from vertical to horizontal. Heathfield's full- post- BBC mux is on (this is what Newhaven is rebroadcasting on ). All other digital channels from Heathfield are still on their pre-DSO low power and so may be unavailable.

There isn't forced to be a need to replace the lower grade . With digital, there is signal strength and signal . The strength needs to be above the threshold at which the will resolve a . Signal strength can vary a little, e.g. with the weather. With analogue, a slight variation would have some direct impact on the picture, maybe slightly more grain. With digital, there will be no impact unless it puts the level below the threshold, at which point the picture will be lost or perhaps intermittent break-up will occur.

From what you've said, the channels for which some receivers pick up and some don't are those from another transmitter (for which the aerial wasn't installed for and for which you aren't likely to watch). So they may be marginal strength anyway plus the fact that different receivers have differing sensitivity to (presumably) such small signals.

As you're using one aerial for more than one set, then there should be a proper method of splitting the signal. A distribution will ensure that equal levels of signal are given to each feed. An unpowered splitter may be sufficient where there is sufficient signal going in.

The downleads should not be connected under the aerial terminals or connected using a terminal block or twisted and taped together; a proper splitter should be used.

If you are looking at DIYing, or just wish to be briefed before getting in a professional, then have a look at www.aerialsandtv.com which has a page with guidance on selection of aerial for the transmitter: Heathfield Transmitter

David,
It's day so that's why. At 6.45 I checked and found the other 3 analogue signals have gone, but no new digital ones.

As this site has pointed out, a full rescan done after 9am should get the full 'Freeview Light' package.

... and at8:30 50 is . What chaos it must have caused for people who returned while 50 was off.

Just retuned and all on up and running!

As engineers have to commute to relays, they can take longer to get back up and running, particularly if there's many of them.

UK published the times at digitaluk.co.uk/heathfieldrelaytimes

Some relays are due to be back on mid-morning and others are due mid-afternoon.

My points direct to .

But I notice in Newhaven, many house down the hill have top aerials that point to including a friend of mine. He was getting the , but will he get the digital signal?

He has asked me to set up his TV when he gets back from holiday, I just he won't end up with a blank screen.
Will he have to get a new 'vertical' aerial pointing at the Newhaven transmitter?
