Default NVIS and VHF?

I'm living in a wooded area and am trying to hit our club repeater
reliably. It's cloudy now so I'm and getting a bit of ducting but I
have a lot of trees, mostly poplars, in the direct path. I would have a
line of sight if not for the trees as I'm up enough in altitude. I can
cut the trees, they're mine, but finding the right ones is difficult and
i don't want to waste the whole grove.


Wait for winter and use a beam antenna to locate the tree(s) that need to be
trimmed.

If a 10 element beam won't "blast" through the trees in the summer, it should
get you down to a line of 1 or two trees that need to be cut.

A more radio oriented project would be to put a 6m or 10m input on the
repeater. 10m should groundwave over the trees anyway. It's easy enough to
test.

10m inputs are IMHO neat, at the top of the sunspot cycle, they give your
repeater worldwide input. At that point a 10m output would be good too, but
for now, it's not much of a problem.

It's amazing how many people have no clue what the word "contiguous" means. :-(
