Which companies have run the Channel 3 services in the Mendip transmitter area
Dave Lindsay Re Sony pvr seems too much signal was too much have changed aerial connections on distribution amp to mast amp reduced signal to 75% quality 100% on all Mendip channels not had any more problems with unwanted Rowridge channels.Thanks for your advice

Ben Ward: jb38 thank you very much for your advice and suggestions. I have done the tasks you suggested I do, as follows:
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.

My problems seem similar to Ben Wards, as said previously, all channels working fine til about same time (April) - coincidence?. Was going to reply in detail to RG38s appreciated post but as of couple of days ago all seems to be working fine again, except occasional bad picture on borderline channels. Just for the record though my line of sight to Mendip is slightly more southerly than he imagines from postcode location. I know houses & hill with trees behind that he mentions which are off to the right. From my rooftop there are absolutely no obstructions with clear line of sight to the opposite side of the valley that Bath sits in. Anyway, fingers crossed for now. Thought digital was going to be trouble free but in 40 plus years of analogue never had ANY problems, except occasional transmitter breakdown!

Ben Ward: I realise that this has been brought up before, but the test that you carried out on the Humax whereby it was indicating 100% on strength & quality "still" indicates that you are receiving a slightly over the top signal, but though! I would like you to check something by going into the Humax's installation menu / antenna power and confirm that the antenna power selector is set to off.
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.

Lordgeous: That perfectly OK! as I realised it was me you were referring to. I also noted what you had mentioned to Ben Ward regarding your location insomuch that it wasn't quite what the post code would suggest, and indeed I feel that very few ever are when allocated in built up areas and why I had initially qualified my comment by "if its truly representative" etc.
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.
