Some Belmont viewers in Yorkshire have suffered a strange effect today which
looks as if someone is turning the big volume control up and down at the transmitter. Analogue reception has been fading in and out, or so it would appear, every ten minutes or so. The cause is some of the muxes from Crystal palace, which are co-channel with Belmont analogue. I had endless reports and complaints today about reception. A Waltham analogue viewer in Derbyshire rung to complain of close-spaced horizontal lines on all four channels. CCI from Pontop Pike, 130 miles away, I should think. Emley Moor C5 (ch37) has a sort of mushy look to it, and KB Aerials rung this morning full of wonder to tell me about some foreign muxes that had appeared when he'd installed a DTT box. The most striking example has been a customer with a 700 outlet distribution system near Nottingham. The system has five DTT boxes at the head end. The Tx is Waltham, which is only about 12 miles away and LOS. Normally the incoming signals are very good and strong. But this morning and afternoon all the DTT was pixellated and blocky. Since the alignment for Waltham is almost exactly the same as for CP I suspect CP analogue is the cause of the bother. That must be coming in at a cracking good level to bollox Waltham! Surely it couldn't be Bilsdale, coming in from the rear? Incidentally, when I appeared this evening looking a bit knackered Hil asked, "Been leaping from tree to tree dear?" (a Monty Python allusion). "No," I instantly rejoined, "I've been creaking from rung to rung!" "Yes Charles." she said, which means that she classes the display of wit as pooterish. Today this bloke told me that his grandson wanted a wee for his birthday. Do they make him hold it for the rest of the year, I quipped wittily. I'm sure I'm getting more witty as time goes. on. Sometimes when I'm driving along I just burst out laughing at something I've said earlier. Bill |

One thing I've noticed this week, is that that CCI line pairing effect plays havoc with LCD screen images. You get some very strange effects, including posterized luminance and chrominace detail. I'll take an off screen photo next time it happens. Of course it only affects *analogue' received signals as displayed. -- Mark Please replace invalid and invalid with gmx and net to reply. |

Surely it couldn't be Bilsdale, coming in from the rear? Yes, today had been a great day for DX enthusiasts like me. I've had French + Belgian Band 3 as well as Belgian DTT on CH25 fighting with CP DTT. Also, Channel 5 analogue from Croydon on CH37 managed to render Lichfield (8 miles away, direct line-of-sight) unwatchable for a time. CP and Sandy Heath analogue showing near perfect reception with just a screwdriver touching the aerial socket! Chris. |

I've had a few that have replied "Well I've had a lot of wind lately". If I think they can take it I will say "No I meant any problems with the aerial"!. Nobody else I tell seems to find it remotely funny but I can chuckle to myself for a good 30 mile journey fuelled by that gag alone. |

Thats nothing.....
Here in Northampton, Analogue S4C from Carmel has obliterated SixTV from Oxford. The white S4C channel logo is very visible. In addition the S/N ratio was degraded from Mux A from Sutton Coldfield Mux 1 from Waltham made channel 5 analogue (oxford) unwatchable. Muxes B and C from Sutton Coldfield messed up Muxes A and B from Oxford. Mux A was worse probably due to the QAM64 whereas Mux B uses QAM 16 Wenvoe's 4 analogue channels trampled all over Oxford big 4 analogue channels, rendering it unwatchable. I had Hannington blasting in, with very watchable analogue BBC 1, ITV and BBC2. Ch 5 from Hannington was not watchable due to being co-channel with Waltham's Ch 5. I even managed to get Mux 1 from Hannington. Regards Stephen "Bill Wright" wrote in message ...

Another one is when you say "I'll need to get into the loft" and they say "It's upstairs." And I've told this on here before but I once knocked on the door of a flat where we were fixing the distribution system and said to aged occupant "I want to check your picture." She went in and came out again a few moments later with lipstick on, dragging a hastily cleaned up hubby, and said "We're ready!" She'd thought I'd said that I wanted to take their picture. Bill |

S4C Wenvoe was probably the culprit, that's on Ch 47 Wenvoe's 4 analogue channels trampled all over Oxford big 4 analogue channels, rendering it unwatchable. Ah, no that would have been the big 4 from Carmel (or possibly Beacon Hill). -- Mark Please replace invalid and invalid with gmx and net to reply. |

Once again I "enjoyed" Emley Moor crashing over Sutton Coldfield (we're 30 miles south of SC) and my in-house Sky distribution on 67 became really grainy. I know MUX B from Winter Hill is on 67, is that a likely cause from a north facing aerial? |
