¥Turn the M.CH/VFO.CH control clockwise to increase the frequency; counterclockwise to decrease the frequency.

Due to the large step sizes available, you can quickly move across the band. When the minimum or maximum receive frequency for the transceiver is reached, turning the M.CH/VFO.CH control will not decrease or increase respectively the frequency.

Menu No. 44 (STEP.ADJ) affects how the M.CH/VFO.CH control tunes. When Menu No. 44 is ON (default), rounding occurs on the first step (ÒclickÓ) of the M.CH/VFO.CH control as shown below:

Example 1: Menu No. 44 (STEP.ADJ) is ON

¥Menu No. 43 (CH. STEP): 10 kHz step size

¥Selected frequency: 14.261.73 MHz

Turning the M.CH/VFO.CH control clockwise one step changes the frequency to 14.270.00 MHz, and one more step changes the frequency to 14.280.00 MHz. The rounding occurred on the first step.

Similarly, with 14.261.73 MHz selected, turning this control counterclockwise one step changes the frequency to 14.260.00 MHz, and one more step changes the frequency to 14.250.00 MHz. Again, the rounding took place on the first step.

Example 2: Menu No. 44 (STEP.ADJ) is OFF

¥Menu No. 43 (CH. STEP): 10 kHz step size

¥Selected frequency: 14.261.73 MHz

Turning the M.CH/VFO.CH control clockwise one step changes the frequency to 14.271.73 MHz, and one more step changes the frequency to 14.281.73 MHz. No rounding occurs.

With 14.261.73 MHz selected, turning this control counterclockwise one step changes the frequency to 14.251.73 MHz, and one more step changes the frequency to 14.241.73 MHz. Again, no rounding occurs.

4 OPERATING BASICS

Changing Step Sizes

Select the step size that you prefer for the M.CH/VFO.CH control via Menu No. 43 (CH. STEP). Available step sizes are 1 kHz, 5 kHz and 10 kHz. The default is 10 kHz.

Within the AM broadcast band, the step size automatically defaults to 9 kHz (U.S.A./ Canada versions: 10 kHz) for the AM mode. This step size can be switched between 9 (ON) and 10 kHz (OFF) via Menu No. 42 (BC. STEP). Selecting OFF in Menu No. 42 allows you to use the step size specified via Menu No. 43 (1, 5, or 10 kHz). While in the AM broadcast band, changing the step size via Menu No. 42 will change the selected frequency to the nearest broadcast channel on the next use of the M.CH/VFO.CH control.

If you enjoy listening to international shortwave broadcasters, the M.CH/VFO.CH control is also the best way to manually scan these bands. Select the 5 kHz step size via Menu No. 43 (CH. STEP) since most shortwave broadcasters are spaced 5 kHz apart. Set Menu No. 44 to ON. To listen to a broadcaster on a channel that is not a 5 kHz multiple, use the Tuning control to zero-in to the exact frequency.

FINE TUNING

For SSB, CW, and FSK modes, the Tuning control normally tunes through 10 kHz per revolution of the control. For FM and AM modes, one revolution of the Tuning control changes the frequency by 100 kHz. These tuning rates can be halved via Menu No. 41 (F.STEP).

In addition, the Fine Tuning function reduces the step size of the Tuning control further which allows you to tune more slowly and precisely.
