I live in Watchet is Somerset, I can receive the 10kw channels 21,24,27 no problem. The 20kw channels 22,25,28,29 are weather dependant, sometimes they are fine and sometimes non existent. Seems strange the higher power channels have this problem.

Iain Davies : Stockland Hill's PSBs are 23, 26, 29 @ 50kW and COMs are 22, 25, 28 @ 25kW.
I have given these channels in ascending order, which is not the same order they are in with respect to the multiplexes.
Taking an address on Liddymore Road as a sample location, it is less than 30 miles from Stockland Hill, bearing 160 degrees. While there is no line-of-sight, when compared to the signal path to Ridge Hill it is much better. Ridge Hill is 66 miles out and at 30 degrees. Considering all the high ground between Newport and Monmouth, you're lucky to receive it at all.

Iain Davies : In addition, almost half the signal path from Ridge Hill is over the Bristol Channel/Severn Estuary, so the varying water level may have an effect on the signal.

Iain Davies :
As Steve has explained, it's due to the fact that UHF channels are co-channel with other transmitters and you just happen to be closer to one that's affecting reception of the channels you want, but coupled with which current weather atmospherics (tropospheric conditions that have come with this high pressure system) may be causing further problems with signals from other distant transmitters travelling further and causing interference.
Also one note of correction, UHF C29 PSB2 West is 2kW not 20kW, but because of the mode of transmission used (QPSK instead of 64QAM - it doesn't carry lots of channels) the coverage is almost as good as as the main PSB multiplexes.
