Frequency Navigation - Yaesu FT-2980E Operating Manual

Basic Operation

Frequency Navigation

1 ) Tuning Dial
Rotating the DIAL knob allows tuning in the pre-programmed steps. Clockwise rotation
of the DIAL knob causes the FT-2980R/E to be tuned toward a higher frequency, while
counter-clockwise rotation will lower the operating frequency.
Press the [ MHz ( SET )] 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-2980R/E. Instead of pressing
the [ MHz ( SET )] button, you may also press the [ A ] key on the Microphone's keypad to
engage tuning in 1 MHz steps.
2 ) Direct Keypad Frequency Entry
The keypad of the MH-48
operating frequency.
To enter a frequency from the MH-48
proper sequence. There is no "decimal point" key on the MH-48
there is a short-cut for frequencies ending in zero: press the [ # ] key after the last non-zero
digit.
Examples: To enter 145.520 MHz, press [ 1 ] à [ 4 ] à [ 4 ] à [ 5 ] à [ 2 ] à [ 0 ]
To enter 145.000 MHz, press [ 1 ] à [ 4 ] à [ 5 ] à [ # ]
If you cannot get the radio to accept the frequency entry, it is possible that
the channel steps are set to an incompatible value (e.g. if you have 25 kHz
steps set, you cannot set a frequency of 145.520 MHz). See page 18 to learn
how to change the channel step size.
3 ) Scanning
From the VFO mode, press the microphone's [ UP ] / [ DWN ] keys momentarily to initiate
scanning toward a higher- or lower frequency, respectively. The FT-2980R/E will stop
when it receives a signal strong enough to break through the squelch threshold. The FT-
2980R/E will then hold on that frequency according to the setting of the "Resume" mode
(Menu "41 SCAN)"; see page 39).
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-2980R/E is scanning. The scanning direction will be reversed. To revert to
scanning toward a higher frequency once more, rotate the DIAL knob one click clockwise.
Press the [ UP ] / [ DWN ] keys again to cancel scanning. You may also press the PTT button
momentarily; scanning will stop, but you will not transmit until you release the PTT button,
and press it again.
If you have enabled the "Severe Weather Alert" feature, you will occasion-
ally notice "WX" channels interspersed with the regular channels you are
scanning. This is normal, because your radio is constantly monitoring for weather
alerts. See page 16.
