23cm beacons

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 .
