Skywarn
Many areas of the country have amateur radio repeaters that have been designated as
"Skywarn" repeaters. During times of severe weather, these repeaters are used to relay
reports of severe weather directly to meteorologists at a local National Weather Service
(NWS) forecast office. Using the Skywarn feature in your scanner, you can easily jump to
Skywarn repeater frequencies and monitor these reports, in many cases hearing about
severe weather in your area instantly as it occurs.
This function lets you quickly move to the skywarn channel (channel 300) from any mode
pressing and holding WX about 1 second. The scanner displays SKY.
Note: To activate this function, you must program your desired Skywarn frequency into the
Skywarn channel.
If you does not program to skywarn channel, No proG appears on the display.
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. For
example:
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.
