Signal Stalker II
Signal Stalker II provides a powerful tool to rapidly detect, monitor
and save frequencies of nearby or high-power transmissions. Signal
Stalker II resembles more expensive portable frequency counters, but
provides many advantages over typical portable frequency counters.
Signal Stalker II is more sensitive than portable frequency counters
and will detect transmissions at a greater distance. Signal Stalker II
rapidly searches the RF spectrum in 1 MHz segments. If it detects a
signal, Signal Stalker II searches in ner steps until the signal source is
found.
Signal Stalker II can search all frequencies, or you can dene
frequency ranges, to avoid ranges with constant activity, such as
paging or broadcast transmitters.
To use Signal Stalker II:
1. Hold the Signal Stalker button ( ) for approximately 1 second.
2. To change the scanned band (All Band or Police/Fire), press
FUNC then Signal Stalker ( ). For a list of Signal Stalker Bands,
see Appendix D.
3. To turn off a bank, press the bank or group number while Signal
Stalker II is active.
4. To turn off Signal Stalker, hold the Signal Stalker button ( )
again.
Priority mode is not available while using the Signal Stalker II.
