Richard Sutton: Well, I suppose that you are now really back to square one, however, the fact of only being able to receive one programme channel on Mux29 could point to a glitch having occurred in the tuners memory store, possibly as the result of receiving the same programme on two different Muxes, but from the same station.
I fully agree with the point made regarding the Humax and manual tuning, therefore, I would like you to try another test on same but by first of all carrying out a "factory default", this procedure being the ultimate way of eradicating problems caused by possible tuner glitches, the important point to observe whilst carrying out the procedure being to ensure that the "format hard drive" box is NOT checked, as this would erase programmes previously recorded, obviously only applicable if box in question is a PVR.
On completion of the aforementioned, carry out a manual scan on only Mux29, this being suffice for the purpose intended.

Richard Sutton: Yes, I was aware of that article as the BBC had also published similar information. But though, as far as the changes referred to are concerned, this, at least to my knowledge anyway, was purely for the purpose of updating the EPG listings to accommodate changes made to the news services, plus also to ensure that Ch4 adverts of the more local variety were received from the appropriate transmitter.
The undermentioned being the BBC links referred to.

Richard Sutton : In addition to that said in my previous reply. The fact of you having observed an increase in the signal strength of Mux29 over that of Mux25, somewhat backs up reports seen of the signal from the former having been biased to favour towards the Gloucester area. Unable to check, as the radiation patterns are withheld.

Richard Sutton: Yes, but have you as yet carried out the "factory default" procedure on your Humax?, this procedure always being one of the last resort as far as a viewer is concerned, as its the only way of correcting any data errors that may have occurred in the system, this action being even more effective if the mains supply to the box is switched off (rear switch?) after having carried out said procedure, "before" any attempt is made at retuning.
I did not initially mention this procedure simply because of it deleting any personal settings that you might have made on the box, whereas an auto-tune minus the aerial doesn't, likewise that had to be tried first. However as that procedure failed to make any difference to the situation, factory default "is" now the last resort.
By the way, this is also known under other names (factory reset / first time installation, etc, etc) dependant on the brand of equipment, but most Humax devices generally refer to it as "factory default", usually accessed via: Menu / Settings / Installation / Factory Default.

js: Yes, that's quite correct, and admittedly I suppose I could have suggested checking this out, but the reason for emphasising carrying out the reset procedure, is because of Richard having already scrubbed that stored in the tuner by carrying out an auto-tune minus the aerial, witnessing the result by a "no signal" warning on any attempt to select a programme channel.
If though the default procedure also fails to rectify the situation, then its time to look at other possible reasons for the problem, such as that suggested by the Freeview help desk of possible water contamination in the coax, although the symptoms experienced with that type of problem usually varies between different devices, seldom the same on more than one.

Richard Sutton : The readings taken from your Sony TV would appear to be perfectly OK, Post Verbi 0 indicating that the errors on the incoming signal have been corrected in the TV's processing circuitry.
Purely out of curiosity, as your Humax PVR is of the latest variety capable of being connected into the internet via Wi-Fi, is the coax feeding the Freeview signal into the Humax / TV positioned well away from the router or any ethernet cables connected into same?, likewise the HDMI cable connecting your Humax into the TV being well away from the coax?.
Another thing I was wondering about being, are you using a powered signal splitter?

John Bailie: This site is not connected in any way with Sky's or anyone else's service department, therefore in order to avoid a call out charge being made against your account, I suggest that you cancel the visit via a normal phone call.

Briantist: Yes, as Yesterday (537 +1 on 538) / Drama (158) and Really (155) work OK on my Sky box minus the card.

Richard Sutton: Sorry for slight delay in replying, but many thanks for the update, the detailed content of having clarified the situation regarding your installation. However on the subject of coax cable spacing where its connected into the box, its really the distance that the coax is kept apart from other cables before it reaches the box that's important, as the screening around the coax is at its most effective close to (within 6" or so) or at the boxes input socket by it being grounded onto the boxes chassis.
However, although I may have enquired about cabling, there is an element of the academic attached to this where your particular problem is concerned, basically because of it also affecting Freeview equipment located in another room, as crosstalk between HDMI / Ethernet and a coax cable only affects the device that the coax is feeding into and not a Freeview device located elsewhere, especially so if said device is fed from a different output on a powered splitter located in another area altogether.
By the way, UK digital's reception predictor certainly rates Lark Stoke as being able to provide the best signal in your area, or in my opinion "possibly in theory", the undermentioned link being to the site in question.
I will certainly be interested on the outcome of your test in the loft!

tony: This in most cases, indicates a short circuit on the coax connected into the LNB output socket, if the message disappears on removing same?, the "F" connectors at both ends of the cable should be unscrewed from the coax and checked for any strands of the braiding touching the middle core, all strands having to be pulled well back over the outer covering prior to screwing the connector on.
That said, if this has happened a short time after a spell of rainy weather? the problem is most likely down to water having entered the LNB's (dish end) connector, particular attention being given to any signs of water contamination on the coax as well as the connector.
