FUNCTION OPERATIONS 4 RIT and ZITX RIT function The RIT function shifts the receive frequency up to 9 999 kHz in 1 Hz steps 10 Hz steps when cancelling the 1 Hz step readout without moving the transmit frequency ZITX function The zJTX function shifts the transmit frequency up to 9 999 kHz in 1 Hz steps 10 Hz steps when cancelling the 1 Hz step readout without moving the receive frequency See on p 7 for function description See on p 7 for function description Push the RIT switch Push the JTX switch CHI appears USB IU IOC JTX appears USB vto VFO JTX 39 nn as ICH Rotate the RIT zlTX control Î UU CH Rotate the RIT ZITX control RIT TX RIT Z1TX D To reset the RIT frequency push CLEAR for 2 sec Reset to 0 00 D To reset the ZITX frequency push CLEAR for 2 sec Reset to 0 00 USB iu IOC nn ED I I IUU UU 0 USB 00 ICH To cancel the RIT function push RIT again EI3 disappears IU IOC nn I I IJJ UU VFO JTX ICH To cancel the zlTX function push ZITX again ZITX disappears NOTE When RIT and ZITX are ON at the same time the RIT Z1TX control shifts both the transmit and receive frequencies from the displayed frequency at the same time Calculate function The shift frequency of the RIT or ZITX function can be added substracted to the displayed frequency USB IU IOC nn ED 1 1 IJJ UU 0 55 While displaying the RIT and or JTX shift fre quency push RIT or JTX for 2 sec RIT Push and hold f j USB U 1 1 IOC OC VFO 39 n nn u uu i ICH PRACTICAL EXAMPLE PRACTICAL EXAMPLE When you find a DX station on 21 025 MHz CW and the station is picking up stations transmitting slightly up from 21 025 MHz You find a DX station operating in simplex however you have not yet tuned your antenna or your linear ampli fier and you do not want to transmit your tuning tone on the DX station s frequency Push RIT and JTX to turn both the RIT and JTX functions ON Rotate RIT JTX to find the DX station s receive frequency When you find the DX station s receive frequency push RIT to turn the RIT function OFF Now you can transmit the DX station s receive frequency and receive the DX station s transmit frequency 21 025 MHz Push JTX to turn the JTX function ON Rotate RIT JTX to more than 2 kHz Push TUNER for 2 sec to tune your antenna Or tune your linear amplifier with key ON in the CW mode Push JTX to turn the JTX function OFF Start transmitting while the station is standing by Start transmitting while the station is standing by 32
