Operating Manual

Vertex Standard Co., Ltd.

This Menu Item determines the low-cut frequency of the DSP HPF filter in the SSB, AM, and FM modes. Generally,

acceptable voice fidelity will be obtained only if you do not set this parameter much above 400 Hz.

MENU MODE No-047 [DSP LPF CUTOFF]

Function: Adjusts the high-cut characteristics of the DSP LPF filter.

Available Values:1000/1160/1320/1480/1650/1800/1970/2130/2290/2450/2610/2770/2940/

3100/3260/3420/3580/3740/3900/4060/4230/4390/4550/4710/4870/5030/5190/5390/5520/5680/5840/6000 (Hz)

Default: 6000

This Menu Item determines the high-cut frequency of the DSP LPF filter in the SSB, AM, and FM modes. Best voice-

mode interference rejection will usually be obtained with a setting of between 2130 and 2770 Hz.

MENU MODE No-048 [DSP MIC EQ]

Function: Sets the DSP microphone equalization pattern.

Available Values: OFF/LPF/HPF/BOTH

Default: OFF

OFF:

This function is disabled.

LPF:

Lower frequencies are emphasized.

HPF:

Higher frequencies are emphasized.

BOTH: Mid-range frequencies are emphasized.

MENU MODE No-049 [DSP NR LEVEL]

Function: Setting of the degree of DSP Noise Reduction.

Available Values: 1 ~ 16

Default: 8

MENU MODE No

050 [EMERGENCY]: USA Version only

Function: Enables Tx/Rx operation on the Alaska Emergency Channel, 5167.5 kHz.

Available Values: ON/OFF

Default: OFF

When this Menu Item is set to “ON,” the spot frequency of 5167.5 kHz will be enabled. To get to this frequency, use the

MEM/VFO CH knob to navigate; the Alaska Emergency Channel will be found between the Memory channel “M-P20U”

and “M-001.”

Use of this frequency is restricted to amateurs operating in (or within 92.6 km of) the U.S. State of Alaska, and it is to be
