My nearest 23cm beacon is (I think) GB3DUN (66km) on Dunstable Downs.
From home in the shack I can only use a 6ele PCB antenna firing out of the shack window. With the leaves off the trees, now is probably a good time to see if I can receive it.
It is very much an obstructed path.
This is a useful distance and bearing calculator if you know the Maidenhead 6 figure grid for both the TX and RX. See https://www.chris.org/cgi-bin/showdis .
