your desired Skywarn frequency into the
Skywarn channel.
If no frequency is programmed in the Skywarn
channel, No proG appears.
signal stalker II
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
desired.
