Your scanner’s Signal Stalker II feature provides 
a powerful new tool for you to rapidly detect, 
monitor and store frequencies for nearby radio 
transmissions. The Signal Stalker II feature is 
similar in functionality to portable frequency 
counters that cost much more than your scanner, 
but provides many advantages over typical 
portable frequency counters. 
The Signal Stalker II allows you to sweep the 
entire range of your scanner’s design frequencies, 
or you can specify those frequency ranges that 
you wish to sweep and exclude ranges that you 
do not want to sweep. This allows you to omit 
frequency ranges with constant strong frequency 
activity, such as those with paging or broadcast 
transmitters. Many portable frequency counters 
will remain locked to a nearby constant signal, 
such as a paging or broadcast transmitter, and 
will not function properly until you have left the 
vicinity of the transmitter.
The Signal Stalker II feature is more sensitive 
than portable frequency counters and will detect 
transmissions at a greater distance. You can 
activate the Attenuator to reduce the sensitivity if
