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 finer steps until the signal source is found.

Signal Stalker II can search all frequencies, or you can define 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.
