Hi. Since several retunes over very few days at the end of May-beginning of June 2012 COM 4,5 and 6 are now very weak. COM6 so weak cannot receive, COM5 comes and goes and COM3 just about holds up most of the time. PSB 1 and 2 are fine. Using Stockland Hill transmitter from North Dorset. Reception was all fine until this happened. Any suggestions. I've done the obvious.
Thanks Ben

Hi. We bought a new Panasonic TV this week which has Freeview HD. We are getting fluctuating signal quality on HD transmissions of 30%-100% - all SD channel quality is 100%. Signal strength is 80%. We sometimes get a "no signal" message - other times we get pixellation for a few seconds - most of the time it is fine. Have done all the usual checks. Thinking of getting a freeview HD PVR but not confident it will work. Our aerial is tuned to Stockland but there is a nearby relay mast - can you advise please.

Sticks: It could be that, having completed its automatic tuning scan, it decides to tune to the adjacent Honiton relay which only carries the three PSBs.
See here for the six multiplexes; each is carried on one signal:
DMOL Post-DSO Multiplex Channel Allocations
This page shows the three PSBs and three COMs.
The automatic tuning process scans UHF channels (frequencies) 21 to 69.
Due to the fact that Stockland's six multiplexes are on channel numbers are all in the 20s and Honiton's three PSBs are in the 40s, the aerial lead can be unplugged at about 30% of the scan.
Confirm by viewing the signal strength screen what each is tuned to:
PSB1 | BBC One | Stockland=C26 | Honiton=C42
PSB2 | ITV1 | Stockland=C23 | Honiton=C49
PSB3 | BBC One HD | Stockland=C29 | Honiton=C45
Check to see what each is tuned to and only perform a re-scan if one or more are tuned to Honiton. If they are all tuned to Stockland, then it isn't a tuning problem.
If you do scan and unplug the aerial after 30%, hold the plug away from the socket (not within a few inches) so as to avoid any possibility of the signal being transferred.
There is always the possibility that the signal from Honiton is so strong where your receiver is located that it could pick it up even without the aerial plugged in, so check that they are all tuned to Stockland. If this does happen, then you will have to see if there is somewhere else that you can take the receiver when there might be less Honiton signal, but where you will have access to an aerial connection. That, or if you can wipe it and manually tune to Stockland, although not all receivers allow this; they vary by design.

Thanks Dave - you were spot on - the set was tuned to the Honiton relay on the HD channels. I re-tuned to Stockland (Ch29) and unplugged the aerial as you suggested but the signal quality and strength is now worse with quality going into the red quite often. Would re-tuning to honiton with a properly oriented aerial (vertical) help?

Sticks: Perhaps the poor HD mux on 29 from Stockland is why it decided to go with Honiton; i.e. the latter is the better of the two.
Whilst receiving from Honiton is a possibility, it will mean that you will then not have any of the COM services (see DMOL link I provided above).
However, as you are just less than four miles from the transmitter, I wonder if your receiver is being overwhelmed by signal and it is distorting, hence the poor quality (HD signals suffering from this before any other).
See here for an explanation and possible remedy:
Freeview signals: too much of a good thing is bad for you | ukfree.tv - independent free digital TV advice
The COMs are at half power with respect to the PSBs from Stockland, so it is to be expected that if you do have too much signal that it will be one of the PSBs that will be affected.

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's: mapS's Freeview map terrainS's terrain plot wavesS's frequency data S's Freeview Detailed Coverage
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!
