Hi,
I was up early this morning (Tuesday 25th September) and heard W5UN come up
on 160m at 0444utc. Though very weak and with deep QSB, he was by far and
away the strongest on my K9AY when switched NE and next strongest when
switched SE. I'm in IO51, he is in EM19; direct bearing is 296 degrees
(WNW), long path is 116 degrees (SSE).
Was he really long path (33428km) or is some other propagation mechanism at
play here?
Hi Cormac,
I have four reversible Beverages giving directions every 45 degrees
around the compass starting at due north 0 degrees. It is not
uncommon to experience DX stations coming in at wildly different
headings from direct path, even 180 degrees off. Often when this
happens, the signal will be there on more than one Beverage,
sometimes all of them! In almost all cases, switching to a low
dipole has resulted in good reception, sometimes better than any of
the Beverages. I suspect the phenomenon is caused by signals
arriving at a high vertical angle, where directivity of the
Beverages is questionable or non-existent. I have no experience with
K9AY loops.
