Adam Jackson:
I'm afraid you are wrong old chap. It is still on 46.
You are most likely picking up PSB2 from the Fishguard relay which is not too surprising considering your location. If your aerial is still pointing at Trefin you should be getting it on C22. If you've recently retuned, changes in reception might be due to strong Tropospheric Ducting which has intermittently been affecting different parts of the UK in recent days.
