Amateurs in Belarus now have access to the new WRC15 60m allocation. Their
band is from 5351.5 to 5366.5 kHz with a maximum power of 50 watts.

This Question and Answer is with Donald G. Everist, P.E., president of
consulting engineering firm Cohen, Dippell and Everist, P.C. In the FCC's
noise floor proceeding, the firm submitted a copy of a 1985 IEEE article
that provides an analysis of noise contribution from a 345 KV transmission
line. He told the commission he provided this information now as
documentation of an approach to make an assessment of noise from such a
line.

ARRL Encourages Comprehensive Noise Floor Study:

In anticipation of an FCC Technological Advisory Council (TAC)
investigation into changes and trends to the radio spectrum noise
floor to determine if there is an increasing noise problem, ARRL
asserted that such a study is long overdue. The FCC Office of
Engineering and Technology (OET) announced plans for the TAC study
in mid-June and invited comments and answers to questions that the
TAC posed concerning the methodologies for such a study. The
League's comments also praised the TAC - an advisory group to the
FCC - for tackling the issue and expressed the hope that the noise
study might, for the first time, provide a useful, objective basis
for spectrum overlays and other future allocation decisions. ARRL
allowed that while a noise floor problem exists, "The magnitude of
this problem and the extent of it in the 21st century is virtually
unknown."
