[IRCA] July 2011 Ultralight NDB-DXpedition Report

[d1028gary@xxxxxxx]

Hello All,

From July 12-18 detailed DXpedition testing was conducted on two new 
Ferrite Sleeve Loop antennas (FSL's) in the ocean beach environment of 
Lincoln City, Oregon. Both a 6.5" diameter Longwave-optimized model and 
an 8" diameter MW-optimized model (both about one cubic foot in size) 
were tested in their ability to provide competitive reception of 
long-distance DX stations throughout their frequency ranges.

The 6.5" diameter Longwave FSL composed of 35 Amidon type 33 
(American-made) 4" x 1/2" ferrite rods managed to provide the first 
Ultralight radio reception of a Trans-Equatorial South Pacific beacon 
from North America-- 270 FA in Apia Upolu, Samoa (1,000 watts at over 
5,000 miles distance from the Oregon beach). The astonishing 
performance of the new FSL is described in the full DXpedition report 
posted at http://www.mediafire.com/?9snw5mr2f504wzv , including 
background details on development of the new antennas. The report also 
contains MP3 recording links for the 7 Alaskan and 2 Hawaiian beacons 
received, as well as a day-by-day report of the challenging conditions 
at the beach.

The companion Medium-Wave DXpedition report is also being compiled, 
describing the South Pacific DXing performance of the new 8" diameter 
FSL model at Lincoln City. The antenna managed to provide reception of 
the all-time new Ultralight DXing country of 666-New Caledonia, as well 
as several other new South Pacific DX stations. Full details on the 
construction and development of the new FSL antennas  will be contained 
in an experimental report to follow.

73 and Good DX,
Gary DeBock (in Puyallup, WA, USA)
