AM underindexes FM at night. In other words, a higher percentage of night
listening is to FM than in the daytime. Part of this is the night
interference on most AM channels,a nd the additional interference coming
from home electronics. HD at night would give AM the ability to compete
better at night by those stations with decent signals, which leaves out
about 75% of all AMs anyway.



Has the radio establishment lobbied as hard for a reduction of
electromagnetic pollution from home electronics as it has for IBOC?

Since it only affects Am significantly, and does not affect AMs with good
signals, we are talking about very few stations that are otherwise viable
being affected. he real issue is that most AMs in the US do not serve
today's metro areas, and in more rural areas, most AMs were killed already
by docket 80-90 drop ins.
