Yeah, Sean is right. Horizontal FM is one way of beating the mush on Great Orme. The SOTAbeams MFD antenna you use facilitates that option really conveniently as well.
Another option is to have a detailed map to hand and make full use of the 25m AZ. Beyond the other side of the car park from the Summit Complex buildings is OK, as, I think, is the mound with the stone messages on the opposite side of the road from the tram station. You can also drop steeply down from the trig below the cable car station and get a little respite from the QRM there.
It is definitely doable on 2m FM, but stood right by the trig point with a wideband HT like the VX7 is certainly making life difficult for yourself! The best option, really, is HF of course.
Brilliant to see you the other day. I hadn’t studied the alerts so was not expecting to meet another activator on Shining Tor, so it was a welcome surprise to notice the instantly recognisable MFD as I climbed the final uphill bit to the summit!
