21FT-7900R OPERATING MANUALFREQUENCY NAVIGATION1) Tuning DialRotating the DIAL knob allows tuning in the pre-programmed steps established for the VFOfrequency. Clockwise rotation of the DIAL knob causes the FT-7900R to be tuned toward ahigher frequency, while counter-clockwise rotation willlower the operating frequency.Press the [MHz(PRI)] key momentarily, then rotate theDIAL knob, to change the frequency steps to 1 MHz perstep. This feature is extremely useful for making rapidfrequency excursions over the wide tuning range of theFT-7900R.2) Direct Keypad Frequency Entry (MH-48 A6J Microphone)The keypad of the MH-48 A6J DTMF Microphone may be used for direct entry of the oper-ating frequency.To enter a frequency from the MH-48 A6J keypad, just press the numbered digits in theproper sequence. There is no “Decimal point” key on the MH-48 A6J keypad.Examples: To enter 146.480 MHz, press [1] Æ [4] Æ [6] Æ [4] Æ [8] Æ [0]To enter 433.000 MHz, press [4] Æ [3] Æ [3] Æ [0] Æ [0] Æ [0]3) ScanningFrom the VFO mode, press and hold in the [SCAN(SEL)] key for 1/2 second, then rotate theDIAL knob to select the bandwidth for the VFO scanner. Now, press the [SCAN(SEL)] keymomentarily to initiate scanning toward a higher frequency. The FT-7900R will stop when itreceives a signal strong enough to break through the squelch threshold. The FT-7900R willthen hold on that frequency according to the setting of the “Resume” mode (Menu #37 (SCANSCANSCANSCANSCAN);see page 75). See page 43 for details regarding the VFO Scan operation.If you wish to reverse the direction of the scan (i.e. toward a lower frequency, instead of ahigher frequency), just rotate the DIAL knob one click in the counter-clockwise directionwhile the FT-7900R is scanning. The scanning direction will be reversed. To revert to scan-ning toward a higher frequency once more, rotate the DIAL knob one click clockwise.Press the [SCAN(SEL)] key (or the PTT key) again to stop scanning.You may also initiate the scanner by pressing and holding in the microphone’s[UP] or [DWN] key. However, in this case, the scanner will sweep frequenciesonly on the current band. If you would like the scanner not to be restricted to the currentband, you may change Menu #46 (VFO.BND) to allow the scanner to hop to the low edgeof the next-highest band when the VFO frequency reaches the high end of the currentband (or vice- versa). See page 77 for details.BASIC O PERATION
