Signal Stalker
Your scanner’s Signal Stalker feature lets you set the
scanner so it detects and then displays the frequency of a
nearby strong radio transmission. You can set the scanner
so Signal Stalker works “in the background” while you are
scanning other frequencies; turn off normal scanning while
Signal Stalker works; or turn off Signal Stalker and use the
scanner normally. You can set the scanner so it alerts you
when Signal Stalker fi nds a frequency. You can also set the
frequency band where you want the scanner to look for
transmissions. You can also turn on the pager screening
feature so the scanner ignores common pager frequencies.
Signal Stalker works well for locating the source of strong
local transmissions, such as mobile and handheld two-
way radios in areas with no other strong transmission
sources; however, if you are in an area with many
transmission sources (such as pager radio transmitters,
multiuse radio towers, traffi c control devices, etc.),
Signal Stalker might not fi nd the transmission you are
searching for, or it might fi nd a transmission other than
the one you are searching for. You can screen unwanted
transmissions by pressing L/O to lock them out. See
“Frequency Skip” for more information.
Signal Stalker cannot detect satellite dishes or any
transmitter with a frequency above or below the
frequency ranges listed under “Setting the Signal Stalker
Options”.
Signal Stalker works better with some types of
transmissions than others. It might not correctly display
frequency information for transmitters using a highly
directive antenna (such as an amateur radio beam
antenna), if there are many transmitters operating at
