From earlier electron flows.....
Duane Vincent was caught asking:
DV> If the FCC does not set standards for scanners or
DV> receivers, then why does my manual for the Uniden
DV> Trunktracker say, and I quote:
DV> Certified in accordance with FCC Rules and Regulations
Part 15, Subpart C as of date of manufacture
DV> Duane KA7JEX
Having knowledge of both the title (and the content) of
Part 15 helps understand the labeling.....
Code Of Federal Regulations Section 47 - Telecommunications
Volume One -- Part 15 "Radio Frequency Devices"
Uniden is a manufacturer of elecronic devices. With most
electronic devices (as compared to animal, agricultural,
textile, or structural items) manage to manipulate electrons
in mysterious ways. This manipulation has been know to
create electromagnetic radiation (radio waves) in various
frequencies of the electromagnetic spectrum. In order to
prevent hazardous or "interfering" emissions from occurring,
the Federal Communications Commission established levels to
keep electronic devices from causing problems with other
electronic devices in close proximity. Electronic devices
are label to show compliance with the rules.
A few examples:
Take a portable AM receiver and place it near your computer.
Turn on the computer (and monitor), and the receiver. Note
the "noise" level on the radio once the monitor is displaying.
The monitor emits interference in the AM Broadcast Band.
Remember the time you were watching a Seattle Seahawks game
on Channel 5, KING Television, the NBC affiliate, and your
better half started to vacuum the rug, or run the blender?
These devices utilize electrons to motivate the rotation of
shafts and motors. These devices are not regulated under
Part 15 of the FCC Rules and Regulations. Annoying, wasn't
it? Had these devices been covered by Part 15, you would
have seen similar labeling concerning compliance.
Ever ride in an airplane? If you have, or if you do, take
a moment to ask for a "quick tour" of the cockpit. Then ask
the pilot what electronic devices which surround the cockpit
that can have adverse reaction to electronic emissions. In
the case of an aircraft, those tiny signals can "literally"
bring any aircraft navigation, autopilot, or communications
equipment to a condition of uselessness. The net result can
be the immediate "grounding" of the aircraft, with or without
a landing strip for support.
It boils down to this.....Uniden is invoking a CYA routine!
