Thankyou Briantist regarding advice on strength of signal [ If you have a signal that shows as 100%, then it is too strong. ] Turned amplifier down on my indoor aerial and after a quick retune I have all my channels back. Thanks again.

We are in a fairly remote location but were previously able to receive nearly all digital channels plus fairly poor quality analogue. Since yesterday's switchover we only get C26 & C29 (ArqA & ArqB) despite following initial install instructions.
Are transmissions still on low power, or do we have a problem? Ta.

CharlieB: What you have mentioned could suggest that you are receiving too strong a signal which is overloading the input of your set and causing blocking, as the two channels you do get are on lower power than the rest of the multiplexes, Ch26 in particular only being on 12.5Kw.

If you have an aerial amplifier try by passing it, if however you do not then if the aforementioned does apply you will possibly require to purchase an attenuator to place in line with the aerial input to your set.

It would have been helpful to know what the signal strength indicates as being on your TV, 100% strength but with no quality being usual if the signal is too powerful.

Thanks jb38. Unfortunately I do have a masthead amp which I cannot access to bypass, switching it off results in no signal at all. Just had another go at retuning with my Philips digibox, picked up some more channels on C25, results below:

C = S/Q
22 = 0-50/0-70 (No channels found)
23 = 0/0
25 = 50/40 (10 TV)
26 = 80/100 (16 TV 1 Radio)
28 = 0/0
29 = 65/45 (18 TV 9 Radio)

While 24, 26 & 28 are fairly stable, 22 fluctuates up and down between 0 and 50 for strength and 0 and 70 for quality.
Any thoughts? Many thanks.

To clarify our location, we are at Corlae near the head of a glen SSE from Cumnock, where the 2 horizontal yellow pixels of coverage are shown on the map above.

CharlieB: Thanks for the clarification regarding location etc, however this now being done on checking reception expected for DG7 area post codes it would appear as though the latter part of your original posting might well very much apply, that of you having a problem! this because no reception being possible is predicted for that area by two separate sites.

That said though, I realise that you reported getting nearly all the channels before switchover, this amazing as the pre-switchover TX power was so low, but the signal strengths you have given are liable to indicate terrain obstructions whereby any signals you do receive are purely by being partially reflected, this not being very satisfactory for digital reception as weather / seasonal conditions can cause large variations in signal strength / quality, this right down to zero in some cases.

I would try fresh (initial from new) scan in a couple of days and see what comes up, but Ch's 22, 25 and 28 are the most powerful out of the six multiplexes, Ch 28 being HD and not indicating on standard box, with Ch's 23,26 &29 operating on nearly half the power of the main ones, albeit you report Ch26 at a very acceptable level!

It would be of interest to know what reception others in your location are getting, not of course that this could be used as a positive indication of what you could expect as a few yards can make large differences in reception when in an iffy area, but I don't really think you can do much that is going to improve things if after rescanning in a day or so the situation is much the same, with Freesat possibly being the only option for reliable reception as the last resort.

Thanks for your help jb38... it does seem odd to be getting such strong signal/quality on just one channel. There is certainly plenty of terrain between us and the transmitter, looks like we might have to move to freesat.

i was getting HD channels through the night not a problem! now there is NO signal at all? can receive all standard channels on high signal strength,23,26,29 report 90-95 signal. as said was lookin forward to HD, even set timer for later ;-( restate that on 28 have 0 signal, even when left on scan of 28 for ages? in this case would an attenuator fix? cos can't understand "all working well, am"...and nothing now.
thank you

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
