Содержание

4 FUNCTION OPERATIONS Dualwatch operation Dualwatch monitors 2 same mode frequencies simul taneously During dualwatch both frequencies should be on the same band because the bandpass filter in the RF circuit is selected for the MAIN readout frequency Program the desired programmed scan edges in the same amateur band See p 52 for program ming Push SPLIT to turn the split frequency function ON Set a desired frequency USB IU IOC I I IJJ LUJ nn Scanning during dualwatch Scanning operates only for the MAIN readout To operate the scan during dualwatch scan on the MAIN readout and use the SUB readout for your QSO using both dualwatch and split frequency operation CH The previously operated frequency appears Push DUALWATCH for 2 sec spurr appears Equalized receive frequency and IPUALWATCH ap pear in the SUB readout This quick dualwatch func tion can be turned OFF p 46 Pushing DUALWATCH momentarily activates the dualwatch with the previously operated frequency IPUALWATCH USB IU 1 1 toe nn IJJ U J appears DUALWATCH VFO I1 nn 135 uu VFO OH 4 CH Set another desired frequency using the sub dial or SUB F INPJ SPLIT VFO iu toe nn 1 1 IJJ UU The MAIN and SUB readout frequencies are equalized and the dualwatch function is turned ON DUALWATCH S meter shows the combined signal strength To transmit on the SUB readout frequency push CHANGE or SPLIT P RIT function can be used for the MAIN readout only ZITX function can be used for the transmit readout MAIN readout when the split function is OFF SUB readout when the split function is ON appears ______ I DUALWATCH SPLIT USB Adjust BALANCE to set a suitable signal strength balance between the MAIN and SUB readout frequencies 31 355 00 Select VFO modes for the MAIN and SUB read outs Set the desired operating frequency for the MAIN readout Push DUALWATCH for 2 sec VF0 CH MEMO CH DUALWATCH 1 USB iu oc nn I I IUJ UU _______________ I USB IU jnn nn I I L IU UU VFO iScH iu zi in nn lot iin C IU UU Push SCAN to start the programmed scan Scan activates on the MAIN readout between the programmed scan edges Transmitting on the SUB readout stops the scan To cancel the scan rotate the main dial or push SCAN Monitor function The monitor function allows you to monitor your transmit IF signals in any mode through the speaker Use for checking the voice characteristics when MIC TONE is adjusted or the transmit low pass high pass filters are in use The CW sidetone functions when MONITOR is OFF in CW mode For DSP equipped type Push MONITOR IN Adjust MONI GAIN while transmitting if desired 35 PHONE GAIN MONITOR P Use headphones to prevent feedback For the DSP equipped type set the TONE control to center position to check the transmit filters characteristics exactly
