HI all,
I currently recieve the Local Oxford TV mux on UHF 29 in deepest Northampton According to the DTG Postcode checker: http://www.digitaluk.co.uk/coveragec...gdis7ov2nn7d76 The one on UHF 29 is moving to UHF 22 and there appears to be a 2nd Local Oxford TV mux appearing on UHF 46 on the 23rd May. Is this the introduction of geographic interleaving due to interference from other transmitters or is there additional channels lauching from the Oxford TX? Open source searching on the internet has not provided me with any answers S. |

He is, I believe, currently preoccupied with other matters. Bill |

Like the extra L-Mux beam at Sutton Coldfield, (and the extra transmission of the London local mux from Hemel Hempstead from April 18th) it's an extra beam of the Oxford L-Mux. As it's Ch 46, and co-channel with COM 6 from Hannington from April 18th, it's unlikely to be a northwards or southwards beam, so presumably another direction where 29/22 has a a null ? I wouldn't worry about it, it'll be the same old crap that is 'That's insert name of your area' -- Mark Please replace invalid and invalid with gmx and net to reply. |

Well,
I had two potential sources of co-channel interference on UHF 29, that being SDN from Waltham and Crystal Palace's London Mux. Despite this, I managed to pick up Oxford Mux with some serious kit and distributed it around my house. CP's local mux has now moved and the S/N has not improved so I can only assume SDN at Waltham may have contributed to a poorer S/N. I also get Sutton Coldfield here too (along with Sandy Heath too) and SC already uses UHF 46. Where I live, Hannington is in line with the Oxford TX so I don't rate my chances of getting Local OXford on UHF 46 much as Hannington wil be using UHF 46. However, CP does use UHF 22 for one of its COM muxes but I've never had any CP channels come through my 4 TV aerials system So I am hopeful I will be able to pick up Oxford Mux on UHF 22 come 23rd May. Stephen.

My god what a mess. It was oh so easy in the vhf days. Brian No it wasn't Brian! Take your rose-tinted glasses off and put the dark ones back on! We had horrendous 'continental interference', impulse interference from trams, motor bikes, lawn mowers and every other damn thing that had spark plugs, which just about everything. We had diathermy patterning if you were within a mile of a large hospital, aeroplane flutter, and ghosting -- oh the ghosting! Bill |
