AMSAT News Service Bulletin 186.03
From AMSAT HQ
SILVER SPRING, MD. July 4, 2004
To All RADIO AMATEURS
BID: $ANS-186.03
AMSAT filed reply comments with the FCC on 22 June 2004 on the FCC Notice of
Proposed Rule Making and Order, WT Docket 03-104, which addresses amending
Part 15 rules for "Broadband over Powerline Systems".
AMSAT notes that Access BPL is almost certain to have impact
beyond the frequencies it actually utilizes. This is true because of two
phenomena implicit in radio. One of these is the generation harmonics and
another is mixing products. Mixing products are generated by combinations of
two or more RF carriers being present in a nonlinear medium such as a
corroded joint in a power line. The mixing products along with the
harmonics, will appear at VHF and higher frequencies. Moreover, being higher
in frequency (shorter in wavelength), they will radiate more readily from
the power lines carrying them than will the fundamental frequencies actually
being used by the Access BPL system.

Dr. Perry I. Klein, W3PK, AMSAT Vice President, Government Liaison,
expressed his appreciation to Ray Soifer, W2RS, Bill Tynan, W3XO and AMSAT
President Robin Haighton, VE3FRH, for their effort in preparing these reply
comments.
[ANS thanks Perry, W3PK for the above information]
