Topband: Price of Copper Going Up

[Bruce]

Had a similar one and junked it out. Could have been from a BC-610 
transmitter. Somewhat  less than half of the weight was copper. The primary 
winding wire was not round, but about 1/4 inch square. (Big & heavy) The 
secondary wire is still in service as radials here in Belfast, Maine.  Take 
care not to injure your back when lifting
