Tone Search Scanning - Yaesu VX-1R Manual

Tone Search Scanning
In operating situations where you don't know the
CTCSS or DCS tone being used by another station,
you can command the radio to listen to the incoming
signal and scan in search of the tone being used. Two
things must be remembered in this regard:
• You must be sure that your repeater uses the same
tone type (CTCSS vs. DCS).
• Some repeaters do not pass the CTCSS tone; you
may have to listen to the station(s) transmitting on
the repeater uplink (input) frequency in order to
allow Tone Search Scanning to work.
To scan for the tone in use:
O
Set the radio up for either CTCSS or DCS Decoder
operation (pages 20 and 21). In the case ofCTCSS,
DIB is displayed; in the case of DCS, llI!EI is dis-
played.
D

When the radio detects the correct tone, it halts on
that tone, and audio is allowed to pass. Press
e
again to lock in that tone and exit to normal opera-
tion.
~~
R. F. Says: If the Tone Scan feature does not
~
detect a tone, it continues to scan indefinitely.
When this happens, it may be that the other
station is not sending any tone. You can press the PIT
switch to halt the scan at any time.
You also can press the Monitor switch during Tone
Scanning to listen to the (muted) signal from the
other station. Tone Scanning resumes about a second
after you release the Monitor switch.
Tone Scanning works either in the VFO or Memory
modes.
