PSB services are already paid for by the licence fee payer. Commercial services have to pay for themselves by generating revenue from advertising, etc. No other form of subsidy is warranted at all.

The channels used to broadcast some of the Freeview services are due to change over the next couple of years or so. That should not change the Logical Channel Number (LCN) shown on your TV set or set top box. It's all in preparation for the clearance of the 700MHz+ band to allow for more mobile services.
There is a list at the top of this page that shows the changes as current understood.

Damaged cables or poor connections does cause selective attentuation, it's a well known occurence and it is impossible to predict which frequencies will be affected by any particular cable fault. So it is very good practice to carefully check all the cables and all the signal connections, unplugging the aerial plug and then re-inserting them into their sockets - making sure you put the same cable back.

If you look at the map above it shows that your area is not covered by the service. It appears to be concentrated mainly in the Home Counties but with limitations to the coverage.

Cwmfelinfach is a Freeview Lite transmitter and, as with all such, there is no plan for any further channels to be made available. This is an entirely commercial descision by the non-PSB broadcasters. They have to cover their costs, of transmitting programmes, from the advertising revenue they try to attract. If the audience is too small to interest the advertisers, as with most/all Freeview Lite transmitters, then there is no attraction to pay to provide those extra channels.
It has nothing to do with paying for a TV Licence as that is required to receive any available channels being broadcast or via the BBC iPlayer.

The blue box below your posting that is titled 'digitaluk trade' states that you should get reliable reception from the Cornholme Freeview Lite transmitter that is just 2km from your post code at a bearing of 88 degrees. The blue box titled 'Freeview Map' shows the signal coverage (when you click on the Cornholme transmitter icon) at your post code should be acceptable for you to get the available channels.
Signals are available on channels 49 (BBC A), 54 (BBC B HD) and 58 (D3&4). These are the PSB multiplexes.

By retuning you have made a poor situation much worse!
The map shown in the Freeview Map link shows that much of Aberfoyle has poor or no reception from the Black Hill transmitter. It does not show a more local Freeview Lite transmitter for that area.
The Darvel Full Freeview transmitter is just east of south from your location but the terrain has numerous obstructions (hills?) ranging from close by to almost 30km away. Reception in these conditions will always be unreliable as the signals do not travel through the hills or mountains. The 'terrain plot' link shows the problem well.
All you can do is ensure that your aerial is mounted correctly and as high as safely possible and is aimed properly. I presume that as most properties appear to be recent builds, your aerial cables are in good order - but always worth checking the cables and connections. You may need some amplification but be careful not to have it set too high, the ideal signal strengths are between 50% and 85% for SD services and between 60% and 85% for HD, never any higher as that causes similar problems to those you are experiencing. Likewise, if the signal strength is too low you will have unreliable reception.
I would suggest that you ask an experienced aerial contractor who know the area well to advise on possible solutions. You should, unfortunately, accept that totally reliable reception may not be possible in this situation.

As previously stated elsewhere, Aberfoyle is poorly served by any Freeview transmitter. The coverage around Aberfot=yle from the Craigkelly transmitter is very patchy, see the map at https://ukfree.tv/transmi…lly.
That being the case, your reception from either Craigkelly or Darvel will be unreliable at best.
Your best option is Freesat providing you can have a dish of adequate size, at least 75cm (anything smaller would be very unreliable in rain or snow), mounted so as to have a clear view towards the satellite orbital position. Freesat carries almost the same range of channels as Freeview and it also a non-subscription service but a TV Licence is still required.

To assist you we need you to provide a full post code please. There could be many reasons for you not receiving local channels. Please will you check with your neighbours as to whether they are receiving those channels.

Ian Martin:
You do not indicate where you live, by giving a full post code, so we cannot check whether there is any fault with transmissions or reception in your area.
But that is unlikely else there would be dozens , hundreds or thousands of complaints about it. As there aren't, that suggests you probably have an aerial fault. Have you asked your neighbours if they have the same problem? Check that your aerial is still in the same place as before the storm and still pointing in the same direction and still with the rods at the same position as before. Then check the aerial cables from the back of your equipment all the way up to the aerial. Check all the connections and that there is no damage to the cable and that water is not entering the coaxial cable. If you are unable to make that check then you need the assistance of an aerial contractor.
