The best AM antenna is a long, straight wire, strung out parallel to the ground around 20' high or so. You only use one wire, the Earth acting as your ground plane. This is of course impractical in almost all real-life situations, but nonetheless I found a decent description of how to do this here: http://www.arrowweb.com/M1/otr/antenna.html The 60Hz hum is either being radiated and picked up by your antenna or possibly being brought in on the power cord and not being filtered out in your receiver. I found a good discussion of how to deal with this at: http://www.wolfenet.com/~kiwa/rxtips.html Hope this helps. --Bob On Fri, Sep 03, 1999 at 01:01:25PM -0700, john pearson wrote: > I want to get AM on my reciever/amp.
