It should be noted that the Redruth transmitter is listed for Planned Engineering this week with "Possible service interruptions"

Saturday 30 July 2020 BBC 1 & 2 showing bad or no signal. After retuning, channel 1& 2 were missing from Channel list. ie list starts at 3 which is ITV.
Checked with next door but one neighbour who had identical fault which occurred same day on 30 July 2020. Aerial is 6 months old and we have had no problems since it was fitted .

I take it you mean yesterday, Thursday 30th.
There is some variable intermittent "tropospheric ducting" around at present - https://www.bbc.co.uk/rec….jpg affecting different areas at different times & not all channels are necessarily affected at the same time or at all.
It was particularly strong yesterday over parts of Cornwall, Devon and the South Coast.
Retuning when you have no signal (for whatever reason) is generally a bad idea as it just clears correct tuning and may indeed pick up signals from distant transmitters which disappear again as conditions change.
You'll need to retune again as conditions stabilise, unfortunately you may have to try several times.
(There are no reported transmitter faults and it's not listed for Planned Engineering).

Hi, I have very poor reception on channel 33 multiplex from the Redruth transmitter, all the other multiplexes are fine all approx the same with at least 90% signal strength and near 100% signal quality,
Any ideas would be gratefully received

There doesn't appear to be any currently listed faults for the Redruth transmitter although there was one on the 24th where the transmitter was briefly off air due to a fault in the early hours.
There has been some "Tropospheric Ducting" around causing interference, see Effect of tropospheric ducting on Freeview | RTIS for a simplistic explanation.
It's been affecting various parts of the UK at different times and there is currently still some that may be affecting reception in parts of mainly the south of the UK. It can be quite variable, come and go within seconds, minutes or hours. It doesn't necessarily affect all multiplexes at the same time or at all. At times it can wipe out your reception.
You are not advised to retune when you have lost signals or they are badly pixellated as this usually just clears correct tuning and you have to repeat a retune when signals are stable. You may have to repeat a retune several times if signals are still disrupted.
If you have continuing problems please post back with more detail and a full postcode so that we can look at predicted reception at your location.

There doesn't seem to be any faults currently listed by Freeview or the BBC for the Redruth transmitter, nor is it currently listed for Planned Engineering. It's unlikely that a power outage would cause loss of just BBC and HD channels. Have the channels returned?
It would be worth checking that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old). Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what signal strengths and quality you are getting for the other multiplexes (groups of channels) shown in your TV's tuning section.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
Have you changed anything in your setup at all?
Make sure you don't have any HDMI leads near unscreened/poorly screened flyleads/aerial leads as HDMI has been known to cause interference.

It would be so Nice to be able to receive channel 51 with Christmas so near, i along with many others living in st, Ives carbis bay with children would welcome it, the
nearest receiver is only down the road in redruth, and 61 would be welcome the rest of the year.
licence payer and it cost's the same as the rest of the country is
paying for all the channels on Freeview

I'm sorry you are incorrect - "licence payer and it cost's the same as the rest of the country is
paying for all the channels on Freeview "
The lLcence fee does NOT pay for all the channels on Freeview, it is your permission to watch LIVE tv whether it be on Freeview, Freesat, Sky or any online player or TV service whilst you are in the UK.
The Licence fee money only funds the BBC, all the other channels are commercial - that is - the operators make commercial decisions about what is commercially viable, what they have to pay in fees for the material they transmit, the fees for transmission of their signals to transmitters and fees for the multiplexes and transmitters that are used (note the situation with the PSB channels is more complex).
The fees for being carried on a given multiplex will depend on the multiplex operator and the specific multiplex and the bandwidth being used.
The multiplex operators have to make commercial decisions about how viable a given commercial multiplex might be on a particular transmitter as well as the capital cost of the equipment invovled (assuming there are available frequencies that won't interfere with frequencies used elsewhere etc) does the transmitter serve a large enough number of households that the advertising returns would be sufficient etc etc.
Sony who previously owned these (now "Great") channels made a commercial decision to move most of them to Local multiplexes in 2019 because of lower costs.
There is simply not enough frequencies available (never mind commercial viability) for Local multiplexes to be provided on all but the small limited number of main transmitters serving large urban centres of population, and those that do are lower power and beamed towards those centres of population.
As I hope you can now see it is not a simple straightforward matter. However there is a simple straightforward solution, the channel is available on Freesat. A lot of modern TVs have built-in satellite tuners (check yours), so all you need to add is a dish and LNB to receive Freesat.

Why can't I get Channel 49 Great TV in the Redruth Area?
