The symbol shows the location of the Black Hill (North Lanarkshire, Scotland) transmitter which serves 940,000 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 Black Hill (North Lanarkshire, Scotland) mast?

I have tried a few Aerial, including Gp B (which allows for most channels but not all), and Group E (which is ok in fine weather and poor in windy) and finally a really good wideband, which seems to do the trick, except of course for HD Mux (although none of the others gave me it either!!)

Yeah I can get signal strength, but only for tuned channels, and as I cannot get anything on channel 59, I have no idea on signal strength there (unless someone can suggest a way of getting it? Sony KDL-40NX713 set).

As for signal strength I am getting the following

Mux 1: 100% Signal Quality and 90% Signal Strength. (checked on BBC1). This Mux is meant to be a Maximum signal according to this site.

Mux 2: 100% Signal Quality and 66% Signal Strength. (checked on STV). This Mux is meant to be a moderate signal according to this site.

Mux A: 0% Signal Quality and 52% Signal Strength. (checked on ITV3). This Mux is meant to be a low signal according to this site.

Mux B: 69% Signal Quality and 50% Signal Strength. (checked on BBC4). This Mux is meant to be a Maximum signal according to this site.

Mux C: 66% Signal Quality and 50% Signal Strength. This Mux is meant to be a Maximum signal according to this site. This Mux is playing up currently though.

Mux D: 100% Signal Quality and 50% Signal Strength. (checked on Yesterday). This Mux is meant to be a Maximum signal according to this site.

Mux HD: nothing, cant even manually tune!

Sorry about the channel number. I got confused by the table at the start and misread the display information on the TV also. I'm still puzzled. I'm getting 100% signal strength on BBC4 and I live a lot further away from you. My set is also a Sony. My only other suggestion is that I think I read somewhere that the temporary signal is directional. Maybe a bit of Google research would clarify this.

Found it

Hill is planned to transmit a pre switchover low power HDTV MUX (on CH59 at 10kW) from Feb 2010. Its radiation pattern is the same as that for analogue C5, which is concentrated in a cross shape, due N, S, E and W, i.e. it is nominally omnidirectional."

Not sure if this means a weaker signal if you are NE, NW etc.

I have now had a play with the direction of the aerial, and move moved it nearer to 65 degree (54 is meant to be optimal), and have managed to improve the signal quality and strength across all Mux's, getting no less than 70% quality on any Mux, but still NOTHING on channel 59 HD Mux. Grrrrrrrrrr

I can only think to try a Masthead amp at about 8-12dB and see if it can boost it enough to pick it up.

I think for £25 it's worth a try.

Otherwise I can only wait and hope when the 'volume' gets pumped up at DSO in June I can suddenly receive HD. (55.8005,-4.0147)

Hi Scott,

Yeah thats a great site, I got a lot of good advice from them (and purchased my aerials from them)

I am aware, as you said, about the cross shape broadcast pattern, and that may very well be the issue as I am NE relative to the transmitter, the suggested aerial direction being 54 degrees. I have found that i need to move the aerial more towards 60 degrees to ensure a good signal on Mux C (channel 55), as if I move nearer 54 degree I loose Mux C.

I am wondering if I move towards 69-72 degree I would then move into East, and 'might' suddenly get HD Mux.

Might be worth a go tomorrow, although knowing my luck, I'll get HD and loose something else!!! (55.8005,-4.0147)

That should be I am SW relative to the transmitter, hence my aerial points NE (55.8005,-4.0147)

HI Scott, any chance you have easy access to your aerial?

Only if you do have east access, can you stick a compass along the central spline of the aerial and let me know the directional orientation, if its more or less bang on East (which looking at a map would be correct) I think we may have the answer (that being the cross shaped broadcast pattern!!)

I checked, I am approx. 2miles, NW of Blackhill on no HD recepiton, that is disregarding height issues as mentioned in my previous posts

I wonder if we have worked it out as they say, possible due to very low power and directionality, unless you have a good aerial, clean line and are on a N/E/S/W axis you'll struggle to get a signal?

Only need to find some on an oblique direction to confirm they can receive to blow the theory!

OK, let's put out a call for everyone in direct N,S,E or W of Blackhill, get up on your roof with a compass so we can find out why we can't get HD!

As they say, If something's worth doing, do it yourself!

Hope this is confirmed and I can have increased hope of HD by July
