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.

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).

q Set a desired frequency.
w Push

[DUALWATCH]

for 1 sec.

• Equalized receive frequency and “

” appear in

the LCD. This quick dualwatch function can be turned
OFF in set mode. (p. 100)

• Pushing

[DUALWATCH]

momentarily activates the du-

alwatch with the previously operated frequency.

e Set another desired frequency using the tuning dial.
r Adjust

[BAL]

to set a suitable signal strength bal-

ance between the main and sub readout frequen-
cies.

• S-meter shows the combined signal strength.

t To transmit on the sub readout frequency, push

• 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.

• “

” appears.

e Select VFO mode for the main readout.
r Set the desired operating frequency for the main

readout.

t Push

[DUALWATCH]

for 1 sec.

• The main and sub readout frequencies are equalized

and the dualwatch function is turned ON.

y Push

[(F-5)SCAN]

to select the scan screen.

• Push

[EXIT/SET]

several times to close a multi-func-

tion screen, if necessary.

u Push

[(F-1)PROG]

[(F-2)

∂

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.

i To cancel the scan, push
