 Hi All
 
 In listening to my AM radio at night, I notice that when I put my hand on
 top of the radio, it acts like an antenna and brings the signal in much
 stronger.  Would it be possible to hook a long wire to a piece of
 aluminum and set it under the radio to act as an antenna??  If not, how
 can I hook an antenna to an A.M. radio to make it play better.  73

Take a LW and stretch it out and loop the other end several turns around the 
radio in the same direction as the loop (try the other way also).  Add a 
series BC variable to the ground of the radio or back on it self.  Some combo 
of this will couple in some RF that you will notice.  Or better yet try this. 
 Run the so called LW just to a ground and do the same thing.  The ground 
side of the 110 line works great.  Find the grounded wire first of a 2 wire 
line with a neon lamp.   Use the 3rd in-between wire of a 3 wire line.  You 
will find out how good a ground connection is for a BC AM antenna when 
properly tuned with a 1000 uufd variable.  They try it on 160M then be 
prepared for another surprise.  Hook it to an oil tank for a great high 
surface area ground.  It works great on Xmit also.  K7GCO
