In the UK I think its more the case of a better house then a better antenna first.
Or just go up a mountain, which tops it all.
Would it make sense to search the whole DB for invalid HB/ calls?
When I uploaded my log for HB/BE-104 Chasseral, I found for example HB/G7KXZ/P 30 Apr 2013.
I wonder if this activation is valid or not and if only correcting the activator log would be enough. What is with the chaser logs?
