Re: [IRCA] Beverage versus DKAZ (was: TP for 20 October from Masset)



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 :-)

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
