[IRCA] FCC Must Get Back into the Inspection Business

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.
