SPREAD SPECTRUM FOUND IN THE 160 -170 MHz BAND
Who is using frequency hopping, spread spectrum emis-
sion in the 10 MHz between 160 - 170 MHz?
I've monitored daylight transmissions of this type
using an HP8558B spectrum analyzer and outdoor ground
plane. The signal strength on each discrete frequency
is constant, about 10 db stronger than the Chicago's
NOAA Weather Radio station on 162.55 MHz (35 miles east
of me, atop Sears Tower).
