Dualwatch Operation - Icom IC-756PROIII Instruction Manual

5
FUNCTION FOR RECEIVE

■ Dualwatch operation

Dualwatch monitors 2 frequencies with the same mode
simultaneously.
During dualwatch, both frequencies should be on the
same band, because the bandpass filter in the RF cir-
cuit is selected for the main readout frequency.
[BAL] [DUALWATCH]
RIT function can be used for the main readout only.
∂TX function can be used for the transmit readout
(main readout when the split function is OFF; sub
readout when the split function is ON).
• Scanning during dualwatch
Scanning operates only for the main readout. To op-
erate the scan during dualwatch, scan on the main
readout and use the sub readout for your QSO using
both dualwatch and split frequency operation.
q Program the desired programmed scan edges in
the same amateur band. See p. 79 for program-
ming.
• If you plan to operate a ∂F scan, programming the
scan edges may not be necessary.
w Push [SPLIT] to turn the split frequency function
ON.

readout.
t Push [DUALWATCH] for 1 sec.
• The main and sub readout frequencies are equalized
and the dualwatch function is turned ON.

tion screen, if necessary.
u Push [(F-1)PROG] or [(F-2)∂ ∂ F] to start the pro-
grammed scan or ∂F scan, respectively.
• Scan activates on the main readout between the pro-
grammed scan edges or within the ∂F span.
• Transmitting on the sub readout stops the scan.
