Re: [IRCA] Skywave Noise
Craig,
Walt Salmaniw would be a good choice for someone to "put a BOG at the end
of a peninsula aimed straight out to
sea". His vacation cottage on the Queen Charlotte Islands (BC) is a few
miles from an incredible, very isolated
peninsula jutting out into the Pacific. The view of the ocean and the
Hecate Strait is nearly 360 degrees around!
Perhaps he could take a 4x4 vehicle (the only way to access the property)
to the location, power his laptop and
Perseus receiver by battery, and check the noise levels through the sunset
period. However, he may need to camp
and spend the night there to do this investigation; the poor excuse for a
road to get there and back is treacherous
even in the daytime.
Alternatively, his cottage is also quite remote with a low noise level, and
on the Pacific facing Alaska. The same test
with an SDR (due to the typically very accurate signal meters) right from
his cottage would be informative due to its
isolation and long distance from broadcasters.
Walt, are you up to some DXing from the Queen Charlottes in the name of
research? <g>

The overall noise level has increased significantly in the past couple of
decades. This noise will propagate just like a radio station. Since it
comes from every direction, it really can't be nulled. Other than putting a
BOG at the end of a peninsula aimed straight out to sea, there's no killing
it.
Is anyone in a very quiet area daytime that notices the overall noise floor
increase substantially after sunset? Say at an unused frequency like
495KHz?
This may be a factor in why weak DX stations simply aren't heard like they
were in years past.
Anyone know the next scheduled major blackout? (grin)
