1 PANEL DESCRIPTION r ANF/METER KEY ANF METER (p. 51) ➥ Push to turn the Automatic Notch Filter function ON or OFF in SSB and AM modes. • " " appears on the display when the automatic notch filter function is turned ON. ➥ P ush and hold for 1 sec. to toggle the meter function; (pgs. 30, 60) PO ➟ SWR ➟ ALC • PO : indicates the relative RF output power. • SWR : indicates the SWR over the transmission line. • ALC : Indicates ALC level. 4 What is the Automatic Notch Filter? The Automatic Notch Filter is a narrow DSP filter that automatically identifies and attenuates beat tones, tuning signals, CW, etc., even if they are moving and removes them from the receiver passband while preserving the desired signal's frequency response. t KEYPAD = ➔ ➥  V/M , A/B , SPLIT , MW , M-CL , AGC , COMP , SCAN , VOX , RIT and MNF keys are available. (p. 5) ➥ After pushing and holding F-INP ENT BAND for 1 sec., push a key on the keypad to select the operating band. (p. 24) • The band stacking register is available. • • GENE selects the general coverage band. ➥ After pushing F-INP ENT BAND , push a key on the key- pad to enter a numeric frequency. After entering, push F-INP ENT BAND . (p. 25) • e.g. To enter 14.195 MHz; Push F-INP ENT BAND , 1 1.8 , 4 10 , • GENE , 1 1.8 , 9 28 , 5 14 and F-INP ENT BAND . y RIT CONTROL INDICATOR (pgs. 44, 61) Lights orange when [M-CH] control (u) acts as the RIT control. u M-CH/RIT CONTROL [M-CH] (inner control) ➥ W hile in the set mode/quick set mode, rotate to select the set mode item. (p. 70) ➥ T his control can act as the memory channel control or RIT control. • The RIT function should be turned ON in advance to activate this control as RIT control. (p. 44) - " " appears when the RIT function is turned ON. • The RIT control indicator (y) lights orange when this control is activated as the RIT control. During [M-CH] acts as the M-CH control: Rotate to select a memory channel (p. 61). OFF M-CH Channel increases Channel decreases During [M-CH] acts as RIT control: Rotate to shift the receive frequency (p. 44). • Rotate the control clockwise to incerase the fre- quency, or rotate the control counterclockwise to decrease the frequency. • The shift frequency range is ±9.999 kHz in 1 Hz steps (or ±9.99 kHz in 10 Hz steps). Lights orange RIT Frequency increases Frequency decreases 4 What is the RIT function? The RIT (Receiver Incremental Tuning) shifts the receive frequency without shifting the transmit frequency. This is useful for fine tuning for stations calling you off-frequency or when you prefer to listen to slightly different sounding voice characteristics, etc. • About the [M-CH] control activation: RIT control indicator (y on p. 2) Lights OFF indicator (!6 on p. 8) Appears Disappears Acts as the RIT control N/A Acts as the memory channel control i M ANUAL NOTCH FILTER CONTROL [MNF] (outer control; p. 51) Rotate to adjust the notch filter frequency to reject an interfering signal while the manual notch function is ON. • The filter width can be set to narrow, middle or wide in the manual notch filter set mode. Low frequency High frequency 4 What is the Manual Notch Filter? The Manual Notch Filter is an adjustable narrow DSP filter that removes tones from CW, SSB, AM or RTTY signals while preserving the desired signal's frequency response. o M -CH/RIT•SET KEY M-CH/RIT SET ➥ P ush to toggle the [M-CH] control activation be- tween memory channel control and RIT control. • The RIT function should be turned ON in advance. (p. 44) • The RIT control indicator (y) lights orange when the [M-CH] control functions as the RIT control. ➥ Push and hold for 1 sec. to enter the quick set mode. (p. 70) ➥ During quick set mode, push and hold for 1 sec. to enter the set mode (p. 70) ➥ During quick set mode or set mode, push to re- turn to normal operation.
