John: Rumster @ 10 miles / 26 degrees is, as you have mentioned indicated (in theory) as providing excellent reception at your location, and although I have my doubts as to whether or not you will receive them the two alternatives to Rumster are Rosemarkie @ 45 miles / 210 degrees and Knockmore @ 48 miles / 165 degrees, the reception predictions for Rosemarkie being "good" on the PSB channels but "variable" on the commercials, Knockmore being the reverse whereby "variable" on the PSB channels but "good" on the commercials.

I do appreciate the point you are making regarding foreign channels at times being better that locals, but that can happen with certain types of atmospheric conditions whereby a signal can be bounced back down to earth again at a considerable distance away from the transmitter, although because atmospheric reasons are involved the signal cannot be relied upon for any length of time, because as soon as these conditions inevitably start to change the signal can vanish just as quick as it was received.

Please can you tell me if I will be able to receive the Full Freeview service from Knock More at this site near Carrbridge called Lochanhully?

Colin Swan: If by "full service" you are meaning the range of commercial programmes, e.g: ITV3, Pick TV, Sky news etc?, then they are already being transmitted from Knockmore, but though your location is not indicated as being able to receive them due to the signal path from the transmitter suffering from multiple line-of-sight obstructions, even the BBC and ITV which is transmitted at a higher power, comes under the status of poor as far as reception is concerned.

Freesat is about the only way you will ever be able to view the full range of programmes, that is if the satellite dish can get a clear unobstructed view of a Southern facing skyline at (approximately) 152 degrees.

Colin Swan : As an afterthought, should you be referring to the Grantown Freeview light relay of Knockmore, located @ 5.5 miles, then it (like dozens more) will not be getting upgraded, as anything other than BBC1 and ITV1 are not connected with the licence fee and as such having to be paid for purely by commercial interests, most of these interests (advertisers) having considered that the costs involved of providing and running the service would not be justified by the returns expected from areas of low population.

Thank you.
Indeed reception at present is from the Grantown relay with its very limited range of stations.
Looking at aerials around this area some appear to be pointing to Knock More and are horizontally polarised so that is why I was wondering if we could erect the correct aerial and thus receive the FULL Freeview service from Knock More. What 'group' aerial is required? If it could be mounted at a reasonable height then maybe reception would be possible!
I was not aware that ITV 1 was 'connected' to the licence fee as is BBC.
Also ITV2 is on the 'Light' Freeview service but not ITV3 - why is that I wonder.

Colin Swan: What I had mentioned regarding Knockmore not being receivable at your location was based on that seen using Digital UK's postal code based reception predictor, and although information from these sources always has to taken with the proverbial pinch of salt with regards to accuracy, in your particular case the negative predictions given as far as reception from Knockmore is somewhat backed up by the terrain indicator, (not predictor) which as mentioned in my previous reply indicates multiple obstructions to the signal path from that station.

Although you mentioned as having seen a number of horizontally mounted aerials in your area appearing to point towards Knockmore, this station being on a bearing of 56 degrees whereas the Grantown relay is 68 degrees, I carried out a Google Earth rooftop tour in the Carrbridge area (starting at Packhorse Bridge) and could only find one horizontally mounted aerial, all being vertically mounted and pointing towards Grantown.

That said, it might be the case that a few choice spots for reception from the station desired is possible in your particular location, as any horizontally polarised aerial you see has to be pointing towards Knockmore as no other transmitters exist, however its really a case of just how reliable the reception is from that station, this being where it would be prudent to try and make one or two enquiries in the area where you have seen these aerials.

By the way, the aerial required to cover reception from Knockmore would have to be a wide band type, as the channels span from 23 - 60, a Log periodic type aerial used in conjunction with about a 15db (minimum) booster being an ideal choice, the SLX brand 20db variable gain boosters sold by Argos being excellent for this purpose.

Shannon D: Check your transmitter on this site - if its working OK then its your system. Start with loose cables, etc.

Unless I'm misunderstanding something, the post-2017 channel numbers for the Knockmore Freeview transmitter on this site do not line up with what I can see on my TVs and the site here:….pdf
