When I was younger I once tied a wire around the wires of the antenna
bar ( the one with a magnet and wire coil waxed onto the PC board) and
strung it far out about 10 to 15 feet or even more. Once i did that I
started to pick up shortwave frequencies but normal AM frequencies as
well, The only problem was when nightfall came that radio was just
jammed with stations.

Yup, I've done this many times. The local oscillator in a typical BC
set is loaded with harmonics, and the front end selectivity is usually
lacking. These two 'features' consipre to bring in lots of signals.

You might also think about building a simple converter that actually
downconverts SW frequencies to a dead spot on the AM dial. I have posted
the schematic for a simple one he
