Re: [IRCA] Beverage versus DKAZ



Yeah, right on.  Blame me... <g>

It's bee-kaws some email software (M$...) creates messages as .eml files, rather than transmitting as simple text -- and some receiving email software doesn't know how to natively handle that file type.

(Right, Guy?)

Walt,
The body of mark's message is pasted below. I used to have the same problem posting with AOL during DXpeditions, until Theo D. told me to try something else :-) 73, Gary Pasted: Could the anomalous results be from the fact that sometimes at the sunrise or
sunset transition you actually have higher angle pick-up for long haul because
of a tilted ionospheric layer above the receiving site (enabling chordal /
ducted mode propagation reducing the number of ground
reflections)?

An
antenna that is efficient for high angles may briefly outperform otherwise
superior long haul DX (i.e. low angle pick-up) antennas.


There used to be a
station near Madrid, Spain on 1359 kHz that ran big power into a Near Vertical
Incidence Skywave antenna (horizontal dipole?) to push out high angle skip to
penetrate isolated valley areas between mountains.  Here in Massachusetts during
mid-evening the station was no stronger than other high band Spain stations in
the 5 to 10 kW class.  But as dawn reached Madrid, the signal came up and got
crazy-loud, often the strongest station from across the "pond" at the
time.


160-m hams have reported that they have brief periods when a low
dipole or horizontal loop below quarter-wave height ("cloud burner") contacts DX
that their big verticals or high-altitude beams or dipoles miss.  95% of the
time it's the other way around of course.

Mark, I'll have to wait a few days since the body of your email doesn't
show on my iPhone. Walt
