StevensOnln1: I am in Milton Keynes, so I think it is highly unlikely that I am picking this up from the Madingley transmitter.

DC: You are correct, you certainly won't be picking up Madingley in Milton Keynes. The data for the Cambridge local mux is broadcast on Sandy Heath's multiplexes so that receivers which do pick it up know what to do with its channels.

StevensOnln1: Thank you, that is certainly a plausible explanation,

I would like to have been able to confirm that Madingley _does_ carry these channels, but the page for that transmitter (ukfree.tv/transmitters/tv/Madingley) is somewhat incomplete - which of course is not your fault :)

DC: Hmm. You were being polite to call that page incomplete I would go so far as to say that other than the map, the channel information on page is totally inaccurate.

DC: A check on Digital UK's predictior with a Cambridge postcode shows the local mux broadcasting at 1KW from Madingley (Link: Coverage Checker - Detailed View ).

According to a516digital.com Cambridge TV launched on 18th August 2015 and was renamed That's Cambridge back in December 2016 following a change of ownership.

Why is Sandy Heath showing BBC London News? There is obviously a switching fault!
This morning (Tue 14th Feb) it showed London News during the Breakfast breaks.
After News at Ten it is doing the same. I can only presume it was the same at 18:30.

First of all I cannot understand why int the coverage map there are lots of grey areas that appear to lie around A -roads and motorways. According to this map my area in Luton is NOT covered with good signal strength. What causes this shadowing effects? Interference or what?
Second as a scientist I would like access to a dull technical description of the new terminology used. e.g. In polarisation: what is Hmax? or H-5.6 db. I am fully conversant with Vertical, Horizontal, circular or elliptical polarisation but the above appears to be new jargon that needs explaining.
What time of multplexing is employed? Certainly not Space. Frequency division? - then the frequency of every channel should be listed. Time division? This would curtail significantly the effective bandwith and would result in shitty quality with fast moving / HD scenes. Could you give me link to a technical description of the jargon (and the bad English - like multiplexes!) or else some references please. Yes I can understand it I have a B.Sc. in Elelctronic |Engineering and a Ph. D. in Space science. Many thanks, Basil PS. Icannot currently receive Ch 63 which according to your chart is on Com 8 at 578.0 MHz.

Dr Basil Polychronopulos:

The coverage maps shown where signals can be received from a particular transmitter. The 'grey' areas are where the signal is not receivable due to terrain blocking them. The location of roads is irrelevant.

As a scientist you should do a bit of research as all the terms used and mentioned are standard terminology for RF broadcasting. Details are readily available on several websites.

The mulitplexing depends on whether it is a T1 or T2 transmitter, they use a form of quadrature modulation. Again, research will tell you.

Jargon it is not, but it is correct technical language that has been used in the industry for many years.

My MSc allows me to understand it, as well as my many years in the industry. So I would have expected a holder of a BSc in electronics to do a bit of independent research.

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.
