Frequency Navigation - Yaesu FT-7800R Operating Manual

1 ) Tuning Dial
Rotating the DIAL knob allows tuning in the pre-programmed steps established for the VFO
frequency. Clockwise rotation of the DIAL knob causes the FT-7800R to be tuned toward a
higher frequency, while counter-clockwise rotation will
lower the operating frequency.
Press the [ MHz ( PRI )] key momentarily, then rotate the
DIAL knob, to change the frequency steps to 1 MHz
per step. This feature is extremely useful for making
rapid frequency excursions over the wide tuning range
of the FT-7800R.
2 ) Direct Keypad Frequency Entry ( MH-48
The keypad of the MH-48
ating frequency.
To enter a frequency from the MH-48
proper sequence. There is no "Decimal point" key on the MH-48
Examples: To enter 146.480 MHz, press [ 1 ]
To enter 433.000 MHz, press [ 4 ]
3) Scanning
From the VFO mode, press and hold in the [ SCAN ( SEL )] key for 1/2 second, then rotate the
DIAL knob to select the bandwidth for the VFO scanner. Now, press the [ SCAN ( SEL )] key
momentarily to initiate scanning toward a higher frequency. The FT-7800R will stop when it
receives a signal strong enough to break through the squelch threshold. The FT-7800R will
then hold on that frequency according to the setting of the "Resume" mode (Menu #37 (SCAN);
see page 73). See page 41 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 a
higher frequency), just rotate the DIAL knob one click in the counter-clockwise direction
while the FT-7800R 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 frequencies
only on the current band. If you would like the scanner not to be restricted to the current
band, you may change Menu #46 (VFO.BND) to allow the scanner to hop to the low edge
of the next-highest band when the VFO frequency reaches the high end of the current
band (or vice- versa). See page 75 for details.
