James Howe:

It's weather conditions I'm afraid. There is moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK at present. Do NOT retune, it will more likely remove your correct tuning.
These conditions are predicted to ease later on Wednesday.
Despite the incorrect spelling, this link does work - simple technical explanation

Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted.
The BBC have a current warning on their Arrochar transmitter page.

Transmitter engineering: I must be the last person in Arrochar to complain about no tv signal. This has been going on for months and you couldn't care less,

Every day we lose the signal at some time during the day and its always put down to the weather.

We only get about 10 free view channels which is not bad for the area.

For the first time in my life, I am 74 , I tend to agree with the tory party, its time the BBC was scrapped.

James Howe: This is an independent technical help website which is not connected with any broadcaster or transmitter company. The Arrochar transmitter is a small very low power relay which serves less than 500 homes, so it's never going to be commercially viable to provide every channel that is broadcast from a main transmitter. If you provide a full postcode we can see what the predicted signal strength is at your location and whether you might be able to get an improved service from another transmitter.

Just to clear up a couple of misunderstandings in your post, the BBC do not run the transmitter network, it is run by a company called Arqiva who are responsible for maintaining and fixing transmitter faults. Also, the TV Licence is not a subscription and does not entitle you to receive any particular channels. The channels not broadcast from lite transmitters are all run by commercial broadcasters who do not receive any funding from the licence fee.

It seems StevensOnln1 and I were writing replies at the same time.
This is an independent help-site. The transmitter engineering reports are those generated by BBC Engineering (there has been a problem with those appearing here on the relevant transmitter pages recently).

I'm afraid it really has been weather conditions again. There has been some sustained conditions recently which did clear for a while mid-week but have returned again and are currently affecting parts of Scotland, some areas and channels quite severely.

The BBC have reported the recent problems for the last few days (see below for the last 5 days).

The following were the effects on the BBCA/PSB1 multiplex (groups of channels) which carries the BBC SD and Radio channels -
From 4:12:41pm to 5:48:12pm on 21st Jan 2022
From 3:06:29pm on 17th Jan 2022 to 4:10:07am on 18th Jan 2022
From 10:15:57am to 10:52:46am on 17th Jan 2022

These are those which affected the BBCB HD/PSB3 multiplex which carries the HD channels BBC1, BBC2, ITV/STV1, Ch4 and Ch5.
From 9:42:21pm on 21st Jan 2022 This seems to be still ongoing at the time of my checks
From 12:39:43pm to 7:29:58pm on 21st Jan 2022
From 7:07:05am to 7:11:55am on 21st Jan 2022
From 7:03:57am to 8:52:21am on 19th Jan 2022
From 8:50:47am on 17th Jan 2022 to 4:16:59am on 18th Jan 2022

ITV/STV channels may be similarly affected but detailed reports for commercial channels don't seem to appear in the public domain. Both Freeview and the BBC have had general warnings on their relevant pages when tis sort of thing occurs. It's not the BBC's fault. Climate change has a bearing on this happening more frequently. I did give you a link to a simplistic pictorial representation of what happens with "Temperature Inversion/Tropospheric Ducting which seems to accompany High Pressure weather systems more often these days!

It's not just you that has these problems, lots of people in various parts of the UK have had similar problems off and on recently. We had it in December and again just over a week ago. Current conditions may clear a bit Saturday afternoon/early evening but could then return again later and be off and on for maybe a few more days.

If you really have been losing signal every day for a continuous period of several months, then maybe there's some additional problem.
If you provide us with a full postcode, we can look at predicted reception in your locale and may be able to offer further advice to improve things.

You should be able to receive more than 10 channels - 6 BBC TV including the Red Button, and 14 commercial (STV/Ch4/Ch5) including some +1s, and 5 HD channels if your set has an HD tuner.
Tell us which channels you do get.
