Thanks for your thoughts.

Pre first switch over date we didnt get any signal on any digital channel at all- so there has obviously been a huge improvement. However as you rightly point out, while some of our issues since switchover can probably be attributed to issues to do with Hannington, there are probably some problems within our system as well.

We are waiting till the completion of switch over before we worry about changing our system in any way. After this point we will look into an attenuator and other things.

I was looking up the positive offset (my background is pure mathematics not anything technical) is there something I should do to deal with that.

In my post it was really something that I found interesting that channels I got perfectly (the bbc multiplex) and PSB2 claimed to be the same power yet one comes through perfectly and the other not at all. I hadn't considered that the information at the top could be wrong- you may well be right. It was really a matter of interest rather than anything else.

Great to know that it is not our system (at least not only our system to blame).

We have found that the PBS1 multiplex (basically BBC) is fine at pretty much all the time. Looking at the levels, it is no wonder that some of the others are having problems being as they are at such a lot lower signal strength.

Thanks for posting, am hoping that means it will not cost to get this working right

Not here, I have the PBS1 mux, but that is it. I dont even have the Coms5 mux which I did have for a while.

I tried doing a scan with the cable unplugged to reset, however it still found the PBS1, and when I plugged it back in nothing changed
We are GU52 and it does appear to be a black spot, however hte freeview predictors that I have tried have all suggested that we should have full freeview now.

Any thoughts?

I'm going to give it some time but I probably need some sort of booster or something else

Malcolm, you said we were on the same line as you- do you have good signal now?

Hi,
Having waited for switch over I am still only receiving the PBS1 multiplex (with the channels numbered in the 800 rather than with the correct numbering and EPG). For a brief period I received coms5 earlier this week but that is gone again.

My question is this- I wish to carry out the procedure that you have listed above but the device I am trying to sort out is a dvd recorder, as such it has a memory so unplugging does not make it forget the channels that it has.

Any thoughts as to how to get around this? it is of course possible that we live in a small area that is still a black spot but as we get PBS1 perfectly I think this is pretty doubtful. Even so, it would be great to get the proper EPG setup working

Any help would of course be greatly appreciated

No, I don't believe so. If you have never had any digital channels at all then there would be a possibility that you needed a better Ariel. If you have ever received digital channels then as far as I am aware, it cant be the ariels fault the ariels fault.

I carried out a hard factory reset this morning, with the very satisfying result that my channels (only limited to PbS1 i.e. the BBC mux) have for the first timte arranged themselves into the correct digital tv channel numbering. Of course unfortunately I havent gained any that were meant to come through yesterday, but it is still a step in the right direction

Thanks. While the user guide is not helpful a google search bought up the instructions instantly.

My channels are now in the correct place. Unfortunately I have gained no channels at all, so I am still operating with PBS1.

Any thoughts? earlier this week I had coms5 as well although the signal was never brilliant. The bbc channels are coming through perfectly, so why are the other muxes that are meant to be at the same power completely unavailable (PBS2,3).

Maybe I wont ever be able to recieve these though that does seem strange

Is switch over pretty much complete? I am living in fleet , and am restricted to PBS1 (just bbc channels).

I dont get any of the channels on Mux 2,3 which the info claims go out at the same power (50,000).

Briefly a couple of weeks ago I got coms 6- poor quality but it came through. This has now disappeared even though according to the information provided, it is being broadcast at 5 times more power now.

What are peoples thoughts? is this it? will coms 6 come back- I am baffled why it would appear for a while and then disappear again. According to more general predictions we should be able to get the whole range (I realize that these are often not reliable). Should we be looking into attunators or amplifiers or is there still some sort of improvement to come (and does anyone think that either of these things would make any difference anyway)

Any thoughts or explanations would be appreciated

I have had a look and yes PSB1 (PBS1?) is coming through on channel 45 though only with a low percentage (in the few seconds I watched it was between 16 and 31) which means it is quite good these channels break down so little.

41,42,44,47 all come through as 0% (so not a suprise I cant see them), though 44 briefly flashed 18% before showing 0 (none of the others did this). Is this flash significant? It seams odd, surely either it can get signal or it cant.

What I dont understand is why PBS2,3 dont come through at all if they are at the same strength as Pbs1- though I do realize the explanation coould be extremely simple- the signal strength data is wrong.

Adrian, prior to switchover no I didnt receive any digital mux at all. As to your comment about PBS2 that is exactly what I thought, hence the question. If the signal strengths are identical why does one come in perfect and the other not at all.

Dave, I will see if we have a set top ariel to try out, though I find this rather hard to believe it could be the case. Before switchover there was definitely no signal (all the internet signal checkers agreed). In the past we have been in areas which did have good signal and we never had the problem we are currently faceing

Adrian,

Yes I have done what you suggest. I carried that out earlier this week. That was quite nice as it has rearranged the channels into the correct order which before didnt happen.

Dave
You may well be correct. Would this show up on the power check feature on the recorder? I have gone through each of the channels that should be broadcasting other multiplexes. These are all reading absolute 0 (bar one which flickered for a fraction of a second on 18% before giving 0). If it were the case that the signal was now too high, should these readings (which are only to do with signal strength not what is on the signal) come out as zero?
