The bandwidth for AM is, by NRSC, 10 kHz in each sideband... actually, a
little less. This is to avoid 10 kHz harmonics with adjacent channels.


Not harmonics, just plain old splatter.


There are a couple of licensed US stations that have towers in the 100 to
110 degree height range and direct couple to a series fed tower without
tuning because in that degree range, occasionally a perfect match is already
present. This is very rare.

5/8 wave is magic.
