Close Call
Using the Close Call Feature
Unlike searching, which requires the scanner to tune to a frequency to
check for a transmission, Close Call RF capture directly detects the
presence of a strong, nearby signal and tunes to that frequency.
Close Call RF capture works great for finding frequencies at venues
such as malls and sporting events. You can set the scanner so Close
Call detection works "in the background" while you are scanning other
frequencies, turn off normal scanning while Close Call is working, or turn
off the Close Call feature and use the scanner normally. You can set the
scanner so it alerts you when the Close Call feature detects a frequency.
And you can also set the frequency bands where you want the scanner
to look for transmissions.
The scanner also automatically stores the last 10 hits received into a
temporary bank called "Close Call Hits" in any Close Call mode. The hits
go away when you cycle power. You can also store these temporary
frequencies into channel storage banks.
Close Call capture works well for locating the source of strong local
transmissions such as mobile and handheld two-way radios in areas with
no other strong transmission sources. However, if you are in an area
with many transmission sources (such as pager radio transmitters, multi-
use radio towers, traffic control devices, etc.), Close Call RF capture
might not find the transmission you are searching for, or it might find a
transmission other than the one you are searching for.
Close Call works better with some types of transmissions than others. It
might not correctly display frequency information for transmitters using a
highly directive antenna (such as an amateur radio beam antenna), if
there are many transmitters operating at the same time in the same
area, or if the transmitter is a broadcast television station.
