Hi Andy,
>> 2) There is a gap in plentiful station locations
from those around 2000km (Eastern and Northern Europe) to the next group of
US ones at 5000km +
That gap is also known as the Atlantic ocean ;-)
Seriously, it would help if more stations from eg Russia or southeast Europe
were monitoring.
>> 3) WSPR-15 does not have 9dB advantage on
longer paths due to propagation artefacts. Perhaps fading and breaking it
up.
Don't know, we'd really need a side by side comparison to draw
quantitative conclusions. Your announced dual-speed beacon will
probably some good statistics, or alternative we might resort to path
simulations. My guess is that fading may generally be much less severe
for very long distances than for medium ranges.
All the best,

Subject: LF: WSPR-15 stations
monitoring
Here is a list of all the WPR-15 stations
who have heard my beacon signal within the last few days. The
maximum distance of 1900km is about the same as the WSPR-2 transmissions made
earlier this year at the same EIRP. I'm guessing there are a several
reasons here:
1) These summer months give reduced
S/N / propagation and offset the theoretical 9dB gain
2) There is a gap in plentiful station
locations from those around 2000km (Eastern and Northern Europe) to the
next group of US ones at 5000km +
3) WSPR-15 does not have 9dB
advantage on longer paths due to propagation artefacts. Perhaps fading and
breaking it up.
Anyway :
