1-4 PRC1099A-MS
LSB Lower sideband. The information carrying band of frequencies
below the carrier frequency in SSB transmissions.
Scan group A preset group of ALE channels stored in memory to which the
radio scans or listens for incoming ALE calls. The ALE option
must be installed and turned on.
Squelch A radio function (syllabic squelch) that reduces background
noise to a received signal by turning off the speaker unless
audio (voice) is detected. This eliminates the noise between
syllables during normal voice audio.
USB Upper sideband. The information carrying band of frequencies
above the carrier frequency in SSB transmissions.
VSWR Voltage standing wave ratio. The ratio of peak voltage in the
standing wave to the minimum voltage. Standing waves are
stationary interference patterns inside the antenna feed line
formed by forward and reflected RF power.
