RECEIVE AND TRANSMIT
Dualwatch monitors 2 frequencies with the same
mode simultaneously.
During dualwatch, both frequencies should be on the
same band because the bandpass lter in the RF cir-
cuit is selected for the main readout frequency.
q Set a desired frequency.
w Push [DUALWATCH] for 2 sec.
- Equalized receive frequency and appear in
the LCD. This quick dualwatch function can be turned
OFF. (p. 56)
- 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
[CHANGE] or [SPLIT].
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).
DUAL-WDUAL-W
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. 43 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 2 sec.
- The main and sub readout frequencies are equalized
and the dualwatch function is turned ON.
y Push [(F-4)SCAN] to select the scan screen.
- If the start up screen is not selected (if [F-5]s function
is [EXIT]), push [F-5] one or more times to exit.
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.
i To cancel the scan, push [(F-5)EXIT].
