VX-120 OPERATING MANUAL 21REPEATER OPERATIONMANUAL REPEATER SHIFT ACTIVATIONChecking the Repeater Uplink (Input) FrequencyIt often is helpful to be able to check the uplink (input) frequency of a repeater, to see if thecalling station is within direct (“Simplex”) range.To do this, just press the [REV(HOME)] key. You’ll noticethat the display has shifted to the repeater uplink frequency.Press the [REV(HOME)] key again to cause operation torevert to normal monitoring of the repeater downlink (out-put) frequency. While you are listening on the input fre-quency to the repeater using the [REV(HOME)] key, therepeater offset icon will blink.The configuration of this key may be set either to “RV” (for checking the input fre-quency of a repeater), or “HM” (for instant switching to the “Home” channel for theband you are operating on). To change the configuration of this key, use Set Mode Item33: REV/HM. See page 77.VFO SPLIT MODEFor working on repeaters with odd splits, or communicating with astronauts on orbitingspace vehicles, it may be necessary to use non-standard splits between the receive andtransmit frequency. If the application is infrequent enough not to warrant the dedication ofa memory channel for this purpose, the “VFO Split” mode may be used. Here is the proce-dure for going Split:1. Press the [VFO(PRI)] key, as needed, to select VFO-A. Set VFO-A for the desiredreceiving (downlink) frequency (e.g.145.800 MHz).2. Now press the [VFO(PRI)] key, and set VFO-B for the desired transmit (uplink) fre-quency (e.g. 144.490 MHz).3. Press the [VFO(PRI)] key once more to re-establish VFO-A as the “Main” (receive)VFO.4. Press the [F] key, then press the [LOW(LOCK)SET] key to enter the Set mode.5. Rotate the DIAL to select Set Mode Item 50: VFO.SPL.6. Press the [F] key, then rotate the DIAL to set this function “VSP.ON.”7. Press the PTT switch once to save the new setting and exit tonormal operation.8. You will now be operating in the Split mode. When you pressthe PTT switch to transmit, you will observe that VFO-A andVFO-B will reverse positions. The VFO selection indicator “-b-” will blink while thetransceiver is transmitting, this means that the VFO Split feature is now activated.
