FUNCTIONS FOR RECEIVE
■
Dualwatch operation
Dualwatch simultaneously monitors two frequencies.
The
IC-7851
has 2 independent receiver circuits, the
Main and Sub bands
, so that you can use Dualwatch
with no compromises, even on different bands and
modes.
Set the desired mode in the
q
Main and Sub bands
.
Push [DUALWATCH] to select the Dualwatch opera-
w
tion.
• To equalize the SUB band frequency and mode to that
of the
Main band
, hold down [DUALWATCH] for 1 sec-
ond. This
Quick Dualwatch function can be turned OFF
in the
Others set screen
.
(p. 15-13)
(SET [F-7] > OTHERS [F-5] > Quick Dualwatch)
Rotate [MAIN DIAL] or [SUB DIAL] to set the de-
e
sired frequency.
Normally, the
IC-7851
transmits on the
Main band
.
During Dualwatch operation, you can transmit on the
Sub band
by doing the following procedures:
• Push [SPLIT] to turn ON the Split function.
• Push [CHANGE] to switch the settings, such as the oper
-
ating frequency, operating mode, and so on, between the
Main
and
Sub bands
.
NOTE:
• A beat note may be heard, depending on the fre
-
quency combination (3.5 MHz and 7 MHz, and so
on).
• Receiver sensitivity may be decreased when the
same frequency band and the same antenna are
selected during Dualwatch.
