The symbol shows the location of the Selkirk (The Scottish Borders, Scotland) transmitter which serves 24,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Selkirk (The Scottish Borders, Scotland) mast?

Hawick

Lochpark road Hawick TD9 9HZ. I am a retired electronics engineer with experience in large tv distribution systems in 2 hospitals and many home instalations both analogue and digital but have not had this problem before .... which happens to be my own home !
The aerial is outside and what would seem correctly aligned on Selkirk, it had a mast head amp with 3 way splitter at ground level which was very rusty inside so I replaced it as high as I could and fed the downlead to a D/A under the floor at the same time replacing old coax cables. The problem seems to affect the HD channels more than the standard channels and also a few of the minority channels, the field strength is excellent and stable while the bit error rate is mostly good but does dip and dive a lot and at times it dips off the lower end of the scale momentarily at which point you get the "no signal" on the tv , I still have my Horizon field strength meter from my working days and this confirms the indication viewed on the on screen tv display, I have tried the usual stuff like attenuation to avoid too high a signal strength but the problem is the same. This is a first for me to have a good field strength but a BER which is very unstable. Do you think this could be some sort of interference signal or is it likely to be the aerial itself ? or some other, though I understand that neighbors dont have the problem . I would be interested to hear any comments from the experts, thank you

Keith Tait:

Hi. That does sound rather like the problem is probably "Tropospheric Ducting" As the CCI increases, (could be Europe or the UK). the BER increases to the point where the set can't tell if it's a signal and thinks it's noise so the strength goes to zero.
This type of problem doesn't always affect all muxes the same at any given instant and of course will depend on where the CCI is coming from as to which channels may be affected, and of course the ducting can be frequency dependant!

Whilst one coverage map shows parts of Hawick not well covered, predictions for your postcode are good by both the BBC and Freeview.
Both of them have issued warnings over the last week or two about reception being affected by the "high pressure" (hmm, as you probably know such ducting doesn't always come with every high pressure!).
Tropo predictions show it's likely to come and go and be quite variable over the coming days. Nowt one can do about it of course!

When you've had the problem recently are the other muxes affected PSB2/D3&4 and COM4/SDN by any chance?

If the HD mux is a persistent problem, you could try tuning UHF C30 for the Hawick relay as it's so close to you, you may get it off a sidelobe!

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.
