What is Close Call from Uniden.... Here is what they say in the manual

[Mike From Newcastlescan]

From The UBCT8 Manual...

Your scanner's Close Call feature lets you set the scanner so it
detects then displays the frequency of nearby strong radio
transmission. 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. You can also set the frequency
band where you want the scanner to look for transmissions.
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 instantly tunes to the
source's frequency.

Notes:
Close Call RF 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 RF capture cannot detect satellite dishes or any
transmitter with a frequency above or below the frequency ranges
listed in Select Close Call Bands on Page 19.
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.

Every 2 seconds, the scanner checks for frequencies in the range you
specified in "Set Close Call Option" on page 19 and interrupts the
audio when it checks for a Close call Transmission in that range.

I recently got to play with the close call feature on a UBCT-8
I think I'll be keeping my trusty old Optoelectronics Scout 40 some
how.

yep sure 'IF' you have a scout but look at the price and you have to
have 2 things
the 72/92xlt lets you have both together

i hope to try the t8 soon
i have 2x 780s and 760 so dont need another (or do i) :)

[Dallas G]

yep, basically right

put simply- it goes off looking for 'nearby' transmissions on 'any'
freq, even if they are not programmed into your scanner. this happens
every 2 seconds. like priority but on all freqs.

my take on the manual -(MitH)-

Your scanner's Close Call feature lets you set the scanner so it
detects then displays the frequency of nearby strong radio
transmission. Close Call RF capture works great for finding

-(MitH)- congratulations, you now have a scanner with CC.

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.
-(MitH)- it can be on, it can be off (but why would you do that? you
just bought this feature...)

You can set the scanner so it alerts you when the Close Call feature
detects a frequency. You can also set the frequency band where you want
the scanner to look for transmissions.
-(MitH)- it goes beep when it finds a freq in use. you can choose from
a few 'preset bands'

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 instantly tunes to the source's
frequency.
-(MitH)- kool

Notes: Close Call RF 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.
-(MitH)- True, this thing goes crazy at an scene, ie fire or accident.
All services on scene popup and a simple press gives you their audio;
Police, Ambo, Fire, Towies etc

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.
-(MitH)- its smart but not too smart. Pager tones etc CAN be locked out
if they come up.

Close Call RF capture cannot detect satellite dishes or any transmitter
with a frequency above or below the frequency ranges listed in Select
Close Call Bands on Page 19.
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.

-(MitH)- its smart but not too smart. just like its users :)

Every 2 seconds, the scanner checks for frequencies in the range you
specified in "Set Close Call Option" on page 19 and interrupts the
audio when it checks for a Close call Transmission in that range.
-(MitH)- this is the only bit that can be annoying, just like priority.
it goes from what you are generally listening too or scanning and
'listens' on all channels.
this 'break' in transmission can 'silence' whatever you were listening
too
Overall i think it is worth having and has proven itself at a few
events already
the close call can be turned off with 2 buttons so its easy to have on
or off

my 2.2c worth

Yes and no.
If you're listening to it in priority-type scan, you have to turn it fully
on, then off.
Very annoying if you have hit Hold on a channel, and it keeps picking up
digital transmissions.
