Thanks again Dave for your help. The situation is that, when tuned to Stockland, HD channels get 75% strength and quality varies from red to 100% very frequently. On Honiton (with the currently mounted horizontal aerial)they get 90% strength and quality goes from 25%-100% but drops less frequently.I'm not fussed about the COMs channels. If I introduce an RF attenuator should I tune to Stockland or Honiton?
Presumanly if we go Honiton and I re-orientate the aerial vertically (as spec'd for Honiton)then I will strengthen the signal even more and make it worse.
In auto-tune, the TV tunes in to all the channels from both transmitters and then sorts them "geographically" thus using Honiton first. So if I revert to this method of tuning, we should get the channels on the 3 PSBs from Honiton and then those on the COMs from Stockland - or doesn't it work like that??
What strength attenuator should I get?

Sticks: The suggestion of trying an attenuator was to reduce the signal levels from Stockland, with a view to getting its HD watchable.
I suggest a 20dB variable one so it can be adjusted. Here is one such example (other sellers and outlets are available):
VARIABLE ATTENUATOR TV SIGNAL REDUCER 20dB 3 5 6 9 10 12 15 18 DIGITAL FREEVIEW | eBay
If you have a Group A aerial (red tip) for Stockland, then you should be aware that Honiton is Group B. See here for aerial groups:
Aerials, TV Aerial and Digital Aerial
However, group aerials don't receive nothing outside of group. You may argue that the Honiton signal is so strong due to the close proximity that it is OK, afterall, you have already picked up a strong signal from it with the aerial in opposite polarity...
See here for some gain curves which show sensitivities on different channels (these are just examples to illustrate a point):
Gain (curves), Again
You may find that even with what may be an out of group aerial for Honiton, it still picks up too much signal and needs attenuating.
As for tuning, I said to unplug the aerial at 30% to get Stockland and miss out Honiton. So if you start the scan with the aerial unplugged and plug in at 30% you should get Honiton and miss out Stockland.
Remember that the TV only stores channels it "sees" during the automatic tuning process. If you prevent it from "seeing" the ones you don't want, then it won't store them!

Thanks again Dave - I have ordered a variable attenuator and will try it on Stockland. If that doesn't improve things then I will try Honiton with cutrrent aerial set up. It is red tip Group A but, from what you say, worth a try.

Hi Dave - I have tried a variable attentuator but as soon as it starts to cut in it makes the signal worse - so I guess a signal overload is not the issue. Ant other ideas??

Sticks: It could be water in the cable.
HD from Stockland is on C29 which is what Channel 4 analogue used to use. Did you have any issues with reception of that channel?
The only other observation I can make is that despite being so close to the transmitter, you don't have line of sight to it.
The terrain drops down and there are two brows over which the signal is having to go to get to you:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location
These correspond approxiamately to the areas of around about St Michael's Church and Manor House School and both of these areas have trees. So on the brow of those "hills" (shown in the terrain plot above) it would appear that there are objects (trees).

Sticks: I have just noticed that there is a message at the top of this page about engineering works at Stockland Hill and the possibility of it being "liable to interruption".
I would ask, has this always been an issue? But if it has been tuned to Honiton for HD all along, then results may be poor or intermittent.

Sticks: About possible water in the cable, check for damage to the insulation, such as chafing on a roof tile IF you can work safely at heights and have the appropriate ladders and knowledge to do so.

Thanks for all that Dave - I have booked a diagnostic visit with an aerial fitter as even the local relay isn't giving a wholly reliable signal.Will let you know what he finds. Can't do ladders myself.........

Hi. Does anybody know if and when the work on Stockland Hill transmitter will be finished? We have been getting various messages about interruptions and low signal for some weeks now.
Since approx start of June our COM channels have been much weaker with COM6, Channel 28, so low we cannot receive it. PSB 1 and 2 are fine , full strength. We do not use HD. We are in North Dorset, a fair way from the transmitter I know but all has been well since the digital swichover until recently. Have checked all I can think of this end. Thanks, Ben
