| English term or phrase: blanketing | Definition from ATIS Committee PRQC : The interference that is caused by the presence of an AM broadcast signal of one volt per meter (V/m) or greater strengths in the area adjacent to the antenna of the transmitting station. The 1 V/m contour is referred to as the blanket contour and the area within this contour is referred to as the "blanket area." [47CFR]
Example sentence(s): - It is, except that the lower base bias resistor is quite small compared to what you'd expect-- the impedance seen "looking into" the amp is 50 ohms, which (presumably) matches your antenna system, and has a great effect on eliminating out-of-band AM blanketing that so often plagues simple homebrew receivers. tricountyi.net
 - I also tried a 7.040 MHz crystal (40 meters) and, while it certainly worked, I found that the old AM broadcast blanketing was happening again. ares.org
 - Occasionally, stations that cause blanketing interference near their antenna will also pop up in more bizarre items, such as computer loudspeakers, which are not even meant to pick up radio stations. Wikipedia
