Attenuator
When checked, attenuation is enabled when using Spectrum
Sweeper. Attenuation limits the effective range of Spectrum
Sweeper and may help reduce interference from strong local
transmitters. Use the

Delay
Enables or disables delay when using the Spectrum Sweeper

Special Mode
Spectrum Sweeper sweeps through frequency ranges in 1 MHz
blocks, looking for transmissions from nearby strong signal
sources. When Special Mode is enabled, Spectrum Sweeper will
skip any 1 MHz block where you have skipped five or more
frequencies using the
blocks, looking for transmissions from nearby strong signal
sources. When Special Mode is enabled, Spectrum Sweeper will
skip any 1 MHz block where you have skipped five or more
frequencies using the
SKIP
key. Special Mode is useful when
you are close to many high power transmitters that are close
together in frequency. Use the

Frequency Ranges
The frequency ranges that Spectrum Sweeper sweeps are
controlled by enabling or disabling them here. Disabling
frequency ranges that are not of interest helps speed Spectrum
Sweeper up, helping you to find nearby activity faster. Use the
