[Hallicrafters] Todays finds

[James Thayer]

 From my 1957 archives:
	Consol/Consolan.   During World War II, Germany developed a navigation 
system called Sonne, Following the war, the British further developed 
the system under the name Consol and several stations operating in the 
LF band have been installed in western Europe. The U.S. system called 
Consolan, also has several stations operating in the same band.
	Consol and Consolan differ from other hyperbolic systems in that three 
antennas are located in a straight line (antenna base line) and are 
closely spaced. This aid is often considered directional rather than 
hyperbolic because great-circle bearings are plotted from the position 
of the center antenna.
	The usable range of Consol and Consolan is approximately 1,000 miles 
during the day and 1,200 to 1,400 miles at night. Bearings are most 
accurate along a line perpendicular to the antenna base line and 
accuracy decreases toward the baseline extensions. The total useable 
area is approximately 240 degrees for Consol and 280 degrees for 
Consolan.
	Stations were located at Bushmills, Ireland; Ploneis, France; 
Stavenger, Norway; Lugo and Sevilla, Spain.
  	Here is a link to a website detailing the station in Lugo, Spain. 
http://josecadaveira.tripod.com/militaryruins/id80.html with some 
additional details. Also try 
http://frodo.bruderhof.com/longwave/notebook/n52.txt for some other 
insight. I could elaborate more but this is perhaps already more than 
you wanted to know.
