[BC] Expanded AM Band and License Return

[Harold Hallikainen]

I found the article at
http://www.radioworld.com/reference-room/special-report/2006.06.21-03_rw_AM_ex_6.shtml
interesting. I recall the expanded band was introduced to result in a long
term reduction in interference on the AM band. Stations whose removal from
the existing band would result in the greatest interference reduction were
given a preference for licenses in the expanded band. During the
transition, they were allowed to broadcast on both the old and new
frequencies. I thought they were required to simulcast, but from what I
read in this article, that does not seem to be the case. Anyway, these
stations now do not want to give up the old channels. Not giving up the
channels appears to result in an increase in local program diversity, but
does not result in the original goal of interference reduction.
