[RFI] FCC Limits on Harmful Interference

[David Eckhardt]

Even the limits those of us who play EMC/RFI set by the FCC and the EU
would, by most amateurs radio operators, be considered 'harmful'.  The set
limits for radiated emissions which products must pass when evaluated in an
accredited lab are really quite strong 'signals' when dealing with our
hobby.

Personally, I believe all of Part 15 should be revisited and field strength
limits lowered and frequencies increased.  However, the present FCC really
doesn't give much of a rip about Part 15.  Read my QRZ page, especially the
last paragraph - all from real life experiences.
