Your scanner's Close Call feature lets you set the scanner so it detects, alerts you
to, and displays the frequency of a nearby strong radio transmission. You can set
the scanner so the Close Call feature checks for a Close Call hit every 2 seconds in
the background while you are scanning or searching or use Close Call only mode.
It automatically displays the frequency. 'Close Call Do-Not-Disturb' only checks for
Close Call signals when you are not receiving transmissions. You can also set the
frequency band(s) where you want the scanner to look for transmissions. When the
scanner detects a Close Call hit, it alerts you according to the override and alert
settings. You can also set the scanner to Auto Store Close Call hits.
'Hits with Scan' is a special system that automatically stores the last 10 Close Call
hits until you cycle power. The system 'Close Call' is created when you run a Close
Call Auto Store.
The Close Call feature 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. Several factors affect Close Call performance.
Performance is increased with higher transmit power, receive antenna tuned to
the target band, and a low background RF level. Other than the antenna, you
have no control over these factors, but they explain why performance might vary
by both location and time. The Close Call feature works better with some types of
transmissions than others. It might not correctly display frequency information for
transmitters using a highly directional antenna (such as an amateur radio beam
antenna) or if many transmitters operate at the same time in the same area.
