Bill,
Thanks for sharing your thoughts. It is indeed the use the the SDR in
conjunction with the skimmer that creates in me a new level of awareness of
propagation behaviour.
It is indeed the continuous beacon monitoring over the day (and sometimes also
during night) that makes a big difference. The skimmer really never misses
anything even if it lasts just a few seconds. On the basis of the skimmer's
data output I often tune my active ham work to times of enhanced propagation.
Unexpected propagation is thereby also exploited for the hobby.
Given the low expenditure (< $350), I would encourage every beacon observer to
consider setting up a skimmer using the FCDP+ SDR. I have provided info on that
on my google site

Dieter,
My thoughts in response to your question.
I figure the seasonal changes for ten meter propagation is a eleven year
occurrence compounded by the four regular yearly seasonal thing.
Almost every year of the eleven reveals a different propagation pattern
during each of the regular four seasons.
Experience has shown that ten meters is "open" at some time, at some place
twenty four hours every day. Its just that the odds are it will not be "open"
at a specific location at a specific time.
Just because the band is "open" doesn't mean there is a receptor at the
location to identify the band opening.
Beacons are more or less located in metropolitan areas around the world.....
extremely sparse in some locations while somewhat saturated in other
areas...... Looking at my logs over the past 22 years I have many times
entered "nothing heard".....sometimes days at a time.
Yes, your Australian location will have "nothing heard" periods also.....but,
the advantage is yours as the "skimmer" catches major portions of the day while
listeners like myself tune the band for only short periods of time.
