 Tuning Dial

Rotating the 

DIAL

 knob allows tuning in the pre-programmed steps. Clockwise rotation 

of the 

DIAL

 knob causes the 

FT-2980R

 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

. 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.

 Direct Keypad Frequency Entry

The keypad of the 

MH-48

A6J

 DTMF Microphone may be used for direct entry of the 

operating frequency.

To enter a frequency from the 

MH-48

A6J

 keypad, just press the numbered digits in the 

proper sequence. There is no “decimal point” key on the 

MH-48

A6J

 keypad. However, 

there is a short-cut for frequencies ending in zero: press the [

#

] key after the last non-zero 

digit.

Examples

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 146.520 MHz). See page 18 to learn 

how to change the channel step size.

 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

 will stop when 

it receives a signal strong enough to break through the squelch threshold. The 

FT-2980R

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

 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.
