Strongly agree that IBOC has been a dismal failure and should be removed
from service in the AM band. The other recommendation that should be
strongly considered is the enforcement of FCC Part 15 rules.
Interference levels have more than tripled here in just the past few
years. Much of it caused by poorly designed "Wall Wart" switching type
power supplies.
In the 1950's through the 1990's, the vast majority of household devices
incorporated a power supply into the cabinet of the device that
performed the function of converting AC power into DC power. Nowdays,
such things are very rare. The vast majority of devices use "wall wart"
switching power supplies, many of these are huge radiators of
interference in the AM Band, often at great distances.
Even ham transceivers, which used to incorporate DC supplies now rely on
external DC supplies entirely. It reduces the overall cost and size of
the product, but the trade off is a lot more interference. The device
can be FCC certified, but often the switching power supply is not
included in that evaluation.
