paul : The above posting of 7th August from "Transmitter engineering" is that taken from the Freeview page "Planned engineering works":

Just to add, Arqiva & Freeview never provide details of what the work entails or how long it will last (some of which may be weather dependant).
It looks as though Sandy heath will still be listed next week as well.
(PS. I tend to agree with about the lack of some further detail).

Steve D,
yes I'd seen the other site, and the sheer number of transmitters being maintained,
suggested either there is a common summer/outdoor maintenance aspect, or, that a shared backbone link between transmitters - microwave ? fibre-optic ? is being worked on.
( guess that the companies paying for advertising on the impacted channels get reduced rates if no one can watch them. )
Thanks
Paul

The list of transmitters having Planned Engineering is not untypical. There are obviously fewer in the winter because mast and antenna work are frequently impractical in adverse weather conditions.

Channel 27 - ITV losing signal
Annoying as Rugby is on?
Report says engineering works 2/10/23 for the week.
Am aware living in Newton Longville MK17 0DJ we are in a semi yellow area, but we have a signal booster to help with that.

barry hardwick: It may be worth looking on channel numbers 800 upwards. This is where duplicate channels are put. They may appear to be in no particular and there could be none, some or a lot, depending on what can be received.
In particular, the Oxford transmitter is the opposite direction to Sandy Heath and you might be lucky and be able to pick it up off the back of your aerial. ITV from Oxford is on UHF channel 44 and it may be worth doing a manual scan of that channel to see if it can be picked up. If your TV has already tuned it in then it will be in the 800s, as described above.

Agree with earlier comments - Ely/Cambs C21+, C27 so, ITV&Three for example,
have been dropping out for 10 minute periods 7/8th Oct after ~9pm.
Switching to freeview play devices, with channels streamed via internet seems only option.
Cheers, Paul

barry hardwick: jpaul:
It could well be current weather conditions affecting you, they have been causing Tropospheric Ducting affecting much of the south coast and southern parts of the country on Saturday and more of the south of the country through Sunday including East Anglia. This causes interfering signals from distant transmitters in Europe or the UK to affect reception of your wanted signals. This can periodically last, seconds, minutes and sometimes much longer - Do NOT Retune.
There is nothing you can do about this apart from wait for conditions to change, or use online streaming if available.
IF you did retune, you be best manually retuning the UHF channels for your transmitter.
The BBC have issued warnings -
