a human: ok then, a more "constructive" post -
1. Carmel might well be closer, but it is not the preferred station for the area, that would be Preseli, which the OP was originally tuned to. Go back to Preseli!
2. Regardless of what your distribution filter saws, arrange for the incoming signal strength from the aerial to be nno more than 80 to 85% anything highter will lead to overloading and corruption.
3. Check the aerial, cable, connectors for any signs of water ingress or damage - rain getting in can attenuate a ssingle mux yet leave the others fine.
4. Do away with the Johnson unit entirely! It's simply not needed and is only complicating the system
A normal active distribution amp is more than enough
5. Make sure the only amplification is just enough to over come the loss in the cables. Do not try to increase overall signal strength using an amp. If it's not strong enough, fit a better antenna
