i. Ch61 on the Humax shows quality and strength both being 100%
ii. On the Panasonic, manually tuning it to Ch61 in the way that you said does result in some signal, as opposed to nothing. Nonetheless, I proceeded with the 2 bottom paras of your posting instructions. Having inserted my attenuator, I turned the knob as slowly as I could but to be honest it was very hard to tell if my twiddling was having any effect at all - quality varies from 0-20% at best; strength varies from 85-100% and both display bars flick around arbitrarily so its hard to gauge any effect, as I said.
Anyway, that's what I found. All our Freeview signals worked fine up until April, as I am sure I've previously mentioned.

The reason for me wanting this confirmed is, that if you witness that reading and yet when you transfer the aerial over to the Panasonic TV-L19C20B and there is virtually no signal, then it can only be caused by either (1) the signal being too strong for the sets tuner resulting in RF blocking or (2) that the sets tuner is not compatible with technical aspects of the signal, or and the reason for the check requested, (3) that your aerial system has a preamp that's being powered by the Humax, and if an aerial amp is unpowered whilst its still in circuit it acts like an attenuator, something which would obviously be the case if the aerial lead was plugged into anything except the Humax.
This probably wont be the case but I would just like it confirmed.
Regarding the Panasonic, as I am not exactly acquaint with that particular model I decided to check out Panasonic's "non-compatible" lists but didn't find it mentioned anywhere.
Regarding that attenuator, these are basically slightly crude devices that work OK unless in a really strong signal area, as in these areas the only variation that's likely to be noticed is a minute segment at one end of the scale, fixed attenuators being far more accurate albeit its hit and miss for a person to get it right first time, as you generally require to have about three of them trying various permutations with different values by placing some in series with each other to increase the level of attenuation.

The curse with digital reception is that its success is based on receiving a signal that stays between two levels, that of always being above a level of low but not at any time exceed a certain point of high, as should at any time these two points be violated then the signal will start to break up or cut off altogether, whereas analogue was far more tolerant and with a person having instant visual feedback if their signal was varying, as indeed all signals do in most non line of sight situations, with grain / speckles starting to show on the picture if the signal level was dropping, the density level of these increasing the more the signal level was decreasing, whereas if the signal strength was verging on the excessively high then this resulted in masses of fine herring bone patterns being superimposed on the screen as well as in many cases thick wavy lines also being seen, these usually accompanied with a ripple or rasping noise being heard on the audio.
The only form of digital reception with a virtually guaranteed glitch free performance is via satellite, as nothing affects that with the exception of a really heavy thundery downpour, and even then its only few a few minutes at the very most with under a minute being more the norm.

Can I just say what a relief it was to discover this site and be able to share information and benefit from your expertise - is it a labour of love for you? (Not my business I know).
Regarding my issues, the main mystery for me is why its all been OK until recently? I've spoken to quite a few other local residents (on Mendip) and I think without exception they all suffer from SOME reception problem. As far as I know no-one's planted a huge tree or built some obstruction between Bath & Wells! I might just ask the local TV shops if they know anything but for now I'm happy to have reasonable reception. Fingers crossed!
Thanks again.L

Transferring the aerial to the Panasonic and doing those tests again showed that strength varies from/flickers between 0-20% at best; quality varies from 85-100% which is pretty much what it was before when antenna power was on, on the Humax.C

Have you as yet tried resetting your Panasonic to its shipping condition? this then followed by an "Auto-set up" automatically starting after the set is switched on again. Another thing I would like you to try albeit that it might be a bit of a bother, is to leave the Humax on the same signal test screen that you had used for your report and then switch off the mains power supply to your 4 way splitter, this followed by a further check being made on the signal level that's indicated the Humax to see if it has changed any by doing this, which of course it should "if" the splitter is working OK, as this is the best way to verify for certain if a splitter or booster is working.
That said though, I noted in an earlier posting that you do refer to a second rooftop aerial, and if this is the case and your Humax / Panasonic is fed directly from this then there isn't any point in trying the power off check on the splitter, although you should still try the shipping condition test on the Panasonic.
NB: Regarding the Humax, although you haven't mentioned as such but its assumed that you did carry out a visual quality check the output from the Humax via a scart coupling into the Panasonic?

Charles StuartWednesday 4 July 2012 10:57PM
My idea is to intercept the aerial cable in the loft and fit a new, higher gain aerial there. (The rooftop aerial is too high for me to get to it.) If the problem is the cable, will a high gain aerial have any chance of working? I'm looking for a solution that avoids having to call out an aerial installer as I have a low income and I do know how to fit an aerial and find the signal.J
jb38Thursday 5 July 2012 7:20AM
However as far as the signal not passing through the box is concerned, make sure that the "power saving on standby" is NOT switched on (if a newer type box) as that will kill the signal.
C
Charles StuartThursday 5 July 2012 7:31PM
Can anyone advise how to tell if the co-axial cable needs replacing?J
jb38Friday 6 July 2012 3:06PM
I fully realise that many people use a high gain aerial in situations such as this but there is always an element of self delusion about the results that's achieved, as an ordinary aerial (pref Log type) with a 10+db amplifier mounted close by will always give better results, thereby I would suggest that an aerial such as the type mentioned used in conjunction with a combined booster / splitter to feed the signal to the various positions is liable to result in a more satisfactory situation.
That said, based on what you have reported even just a booster / splitter used with the present loft aerial would likely be suffice, the log being favoured as it has a virtually even response across all channels provided its not one of the larger versions, a type called a DM log (even DM18) being ideal for most loft situations.
An example of the type referred to seen on the link.

What is weird is that I can now receive the missing channels. I connected up the DVD recorder/player that I hadn't yet connected when I had the problem and it picked up the missing multiplex, though slightly weaker than the others, and then so did the PVR, TV and HD box. Is it possible that there might have been a short interruption to service on that multiplex on the 26th June? I cannot think why else I would have had tuning trouble then but not now.Colin:No problem whatsoever ! J

I use DUK's trade view reception predictor as my main reference source as well as info on transmitter channels etc, and DUK's in common with other reception predictors works purely on an actual post code, so if you click on "Digital UK trade view" 3rd down the list at the right hand side of this posting you will get the prediction for reception at a Shepton Mallet test post code, if though you try the same on your own posting you will (or should) get the disallowed characters indication I mentioned.
The procedure to use is enter your post code in the site settings box provided (top right hand of page) and click on predict, then click on the transmitter name that is then indicated, and finally enter your query under the listings that appears for that particular transmitter.
Other possible reasons for the reception problem you were having could be due to atmospheric conditions applying at the time, or its simply the case that the signal you are receiving is not that terribly high above the reception cut off threshold level and that it had dipped under it, and so whilst reception is OK its always best to make a few signal strength checks across various channels such as 1 - 3 - 50 (only if HD is used) - 10 - 11 -12 as these programme numbers covers all six mux transmitters that's used for Freeview (full service) transmission, then if at any time a programme selected results in a blank screen carry out a signal check "whilst on that programme number" to see what the signal level is indicated as being, because unless the transmitter has failed an indication of strength will always be seen.

@jb38 - I have considered atmospheric conditions but yesterday was about as nasty as it gets with very low pressure. The 26th was a bit better but not much, perhaps a bit like today. If anything, I think the roof aerial may be pointing just a fraction south of the south-west direction it's meant to point. The DVD player gives the easiest to understand signal measure. BBCA, D3+4, SDN and ArqA score 10/10 and ArqB scores 9/10, so there shouldn't be any problem. The machine has worked interference-free with scores of 7/10 and with occasional pixelation with scores of 6/10 and 5/10. The HD box measures BBCB at 99% for signal quality and 100% for signal strength. ArqB is on 56. Could the problem be a signal that's too strong? Or maybe I needn't worry about it any more as I'm now getting the multiplex.C

If you are using a standard keyboard and using the number pad on the right, make sure you have the Num Lock on.
The aerial should be pointing slightly south of SW so that sounds correct.
You loft aerial installation should be fine if you've not previously experience any problems since April.
When you say the roof aerial is minute, how many element does it seem to have?J
jb38Saturday 7 July 2012 2:41PM
All of Mendip's multiplexes transmit on the same power and the levels you see indicated on your DVD device does indeed indicate a strong signal, which of course is possible as although your exact location is not known I did see on the terrain predictor that you are indicated at roughly 16 miles or so from the transmitter.
The only thing that I suggest you do is to verify what one of you two aerials gives the best reception by trying a test using the same device on both aerials, but remember though that the signal levels seen are dedicated to the sensitivity of the device being used for the test, and so the results obtained aren't really valid unless the same device is used on both aerials.
However as you were originally only querying why the signal would not pass through your box which was rectified by switching off the power saving on standby setting, then I will agree that you have nothing really to worry about.
By the way as far as post codes are concerned I fully understand why people are reluctant to give this info, but I generally always qualify this type of request by adding "or at least one from nearby such as a shop" as that is quite suffice, but in any query being made where it involves reception then for obvious reasons the persons location has to be known.

Chris.SESaturday 7 July 2012 4:02PM
Depending on what you have I'd suggest trying channels above 62.C
Chris.SESaturday 7 July 2012 4:10PM
knowing the location, the postcode I provided in my post at 1.27pm is a nearby one. Also considering the "description" of his external aerial (sounds like a 10 element yagi) it is highly improbable that he has too much signal.C
Charles StuartSaturday 7 July 2012 4:45PM
This site seems to change my post code into coordinates. It is BS15 1EF and the house has a nice clear view towards the transmitter. I think that the aerial has fewer than ten elements. My guess is five or six.B
Ben WardSaturday 7 July 2012 6:02PM
I reset my Panasonic back to factory condition etc. as you suggest above. It didn't help sadly. I have noticed that when I do an auto setup or rescan for channels, the system defaults to 'Channel 21' - isn't it meant to be 'Channel 61' for this part of the world?? How do I change it as it seems stuck?
I will tackle the next part of your suggestions this coming week, powering down the 4 way aerial splitter.
nb Sorry if I wasn't clear before, I don't have a second rooftop aerial, all F.V. boxes are and have been supplied from 1 signalfrom our only aerial with a splitter in the attic. One of those signals is further split in 2 for the downstairs (main) TV, to the Humax and (when it was working) to a Sony VTX-D800U.

As far RF outputs go, the lowest channels possible or above 62 should be ok. If you use above 62 you might have to adjust them in the future when that part of the band gets used for Mobile stuff.
Where C is the channel used for RF you can sometimes get interference on the following C+1, C+5, C+9. But as mentioned earlier, if you have several, sometimes there can be weird coss-modulation products as well, so there may be an element of trial & error.
Have a look on the Aerial link that jb38 gave and see if you can identify yours from there. If it's one of the most common, there are pictures about 2/3 down the page where aerial polarisations are shown or further down - contract aerials. I suppose it might even be a 5-bay X-beam if the directors look like X's.
If all your multiplexes are OK now, you may as well forget the previous problem, the multiplex could have been off-air for a short while and it wasn't reported or you may have had a brief spot of local interference. It's unlikely to be cable degradation as the HD mux on Ch.58 and the BBCA mux on Ch.61 (both higher frequencies)seem ok and higher frequencies are usually affected first.
Hope that helps.
J
jb38Saturday 7 July 2012 8:11PM
But though, even if you do not have any channels stored you can still check the signal strength of a particular channel and its maybe best if you try things this way, so press: menu - set up - DVB tuning - manual tuning - and you will see a screen bar indicating a channel number on the right hand side, using the up / down facility via the large round button on the remote control inch the channels up or down "one at a time" until you get to either 54 or 61 when if your TV / aerial is OK the signal strength / quality indication of that particular mux channel should immediately appear and which are ITV1 & BBC1 from Mendip, and giving an update on what's seen.
Matter of fact, it would not do any harm if you went though all five multiplexes (HD n/a on that model) from Mendip one at a time using this procedure, (61 - 54 - 48 - 56 - 52) and likewise making a note of the "pseudo" percentages seen, pseudo as they aren't actually marked as percentages as such but just positions along the bar and so an element of judgment will be necessary, but much more importantly note what colour is seen on the quality bar as it should really be green, although touching on yellow now and again is permissible.
I would like to emphasise that everything I am asking you to check is based on you having reported a high level of signal on the Humax, and as aforementioned in a previous posting that if you use the same aerial lead in the Panasonic it should also produce a picture, but if you do not see anything indicated on either 54 or 61 using the manual test then leave the TV sitting on the manual test screen on either channel and pull out the aerial connection, then replace this with a short length of wire of about 18" minimum pushed into the aerial socket and note if this results in anything being indicated, because if not then that points to a fault on the TV.
By the way I haven't forgotten about your Sony box but this test has to be carried out first, as the only other way you can verify if the TV is OK or not is by trying it out on someone else's aerial system. J

With regards to Charles Stuarts HD signal strength I wasn't actually suggesting that it was too strong, but only acknowledging his report of a strong signal being indicated on his DVD device and informing him of the easy way for anyone to know if their HD problem was being caused by an excessive level of signal.
I do realise that you managed to work out the approximate post code via the coordinates obtained from the terrain predictor, but its a somewhat long winded process and so its much to explain the correct procedure to use when entering a post code into the site settings.
By the way, I likewise have entered Charles's post code into my details for a check.

Ben WardFriday 13 July 2012 2:21PM
As far as the other things you've suggested, using the same aerial cable that gives me normal 90-100% strength/quality on the Humax, but plugged into the Panasonic, only gives me signal strength of between roughly 10% and 30% at best (though with signal quality of 100% each time) when manually checking channels 61 - 54 - 48 - 56 - 52. So rather than green occasionally flickering into yellow, its red occasionally flickering into yellow. I've not yet had time to try the 18inch length of wire you mentioned; could I not get the same effect by using a different aerial cable from the one I know works? (btw I tried a second cable, and no signal appeared at all.)
Thanks.J
jb38Friday 13 July 2012 9:26PM
Everything really hinges on what you have reported regarding the signal strength seen on the Humax as it takes quite a signal to indicate that level on this type of box, and although a Humax is a sensitive device its still capable holding out longer than most other equipment before suffering from overload blocking by an excessively high levels of signal.
The Panasonic on the other hand although being equally as sensitive as the Humax "will" start to suffer from excessively high levels of signal over what the Humax can cope with, and the massive difference in levels seen on the Panasonic's signal check screen when using the ex Humax's aerial can suggest this is indeed applying, and likewise could be causing partial instability in the Panasonic's tuner resulting in totally inaccurate readings, with these (and without exception) always being low
This is about the only thing that can be causing the Panasonic's problems, although if not then the actual TV is defective, this being why the issue of a possible excessive signal has to be verified one way or the other.

The reason I ask, is because on a Google earth check I see that most aerials seem to be perched on top of high mounting poles, and with the property next to the mini roundabout sign having an aerial that's quite inappropriate for the situation that its in whereby its facing into trees, "inappropriate" by the fact of it being a high gain and likewise sharper pick up device whereas aerials of a much lower gain and likewise having a broader pick up pattern are usually far more effective in these type of situations, and with them not necessary being mounted high up unless by doing so clears the top of the trees, as if it doesn't then the aerial is effectively facing into a higher density parts of the tree vegetation.
Have you at any time purely for test purposes tried a set top aerial to verify or not if anything could be received at lower levels, although the impediment (as I see it) with trying this sort of thing in your type of situation is that the signal would be travelling through the gable end of the property, and so its not exactly a fair test.
