A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly
"line-of-sight." This means you cannot usually hear stations that
are beyond the horizon.
UNITED STATES BROADCAST BAND
In the United States, there are several broadcast bands. The stan-
dard AM and FM bands are probably the most well known. There
are also four television audio broadcast bands — the lower three
transmit on the VHF band and the fourth transmits on the UHF
band. You can use your scanner to monitor the 470
tion of the UHF band.
