The sun has an 11 year cycle, and we're heading for a minimum, so the
higher bands like 10m will tend to be dead for long periods of time. But
round about now you should get periods of short skip propagation when
fairly local stations are workable at good strength. Unfortunately, because
so many hams are obsessed with working DX, you're more likely to hear
illegal CB operators than you are hams.
I've tried for a long time to try to get my head around the various things
that affect propagation. I wrote a program, HFProp, which you can download
from my site, that attempts to show what can be worked if you type in the
current sunspot numbers from WWV. For the experts around here, I should
point out that it's a Windows update on the MiniMUF programs in BASIC that
used to be popular years ago, so it isn't that accurate. But it has the
user interface I wanted. The other programs I've seen take a lot of work to
calculate the propagation over just one path, which doesn't give you an
overall picture.

but was unable to all antennas at the local club station are cut for ssb
lengths so i was seeing hi swr when tuning and hi reflected when atempting
to
transmit. also got confirmation from a local ham who had a hand in
erecting
the antennas. the only band i found i had good swrs all the way across was
10M. Now i realize were in a down period cause of the ionosphere and ive
only
been licensed for exactly 364 days(hey hey tommorow i will be a ham for a
year!) but i have never repeat never not once heard anyone licensed
unlicensed
use cw ssb or digital mode at all on 10 M the whole time ive been playing
with
radios. i was told i should wait bout 5years. is this normal bands out for
5years at a time?
