8 COMMUNICATING AIDS

■Equalizing VFO Frequencies (A=B)

This function allows you to copy the frequency and modulation mode of the active VFO to the inactive VFO.

1Select the frequency and mode on VFO A or VFO￿B.

2Press [A=B].

•The frequency and mode selected in step 1 are copied to the inactive VFO.

3Press [A/B] if you want to confirm that the frequency was copied.

RIT (RECEIVE INCREMENTAL TUNING)

RIT provides the ability to change your receive frequency by ±9.99 kHz in steps of 10 Hz without changing your transmit frequency. If the Fine Tuning ([FINE]) function is ON, the step size is 1 Hz. RIT works equally well with all modulation modes and while using VFO mode or Memory Recall mode.

1Press [RIT].

• “RIT” and the RIT offset appear.

2If required, press [CLEAR] to reset the RIT offset to 0.

3Turn the RIT/XIT control to change your receive frequency.

4To cancel RIT, press [RIT].

•The receive frequency is returned to the frequency that was selected prior to step 1.

Note:

◆When using Memory Recall, RIT only functions with a memory that contains stored data.

◆The frequency shift set by the RIT/XIT control is also used by the XIT function. Therefore, changing or clearing the RIT offset also affects the XIT offset.

AGC (AUTOMATIC GAIN CONTROL)

When using modes other than FM, AGC selects the time constant for the automatic gain control circuit.

Selecting a slow time constant will cause the receiver gain and S-meter readings to react slowly to large input changes. A fast time constant causes the receiver gain and the S-meter to react quickly to changes in the input signal. A fast AGC setting is particularly useful in the following situations:

•Tuning rapidly

•Receiving weak signals

•Receiving high-speed CW

The default time constant is slow for SSB, fast for CW, fast for FSK, and slow for AM.

1Assume that USB is currently selected.

2Press [AGC/TONE].

•“FAST” appears and shows that a fast time constant is selected.

3To select a slow time constant, press [AGC/TONE] again.

RX EQUALIZER

RX Equalizer changes the receive frequency characteristics so that you can listen to received signals with the most comfort. Use Menu No. 50 to select from five different receive profiles including the default flat response. Selecting any of the following items from the Menu causes “” to appear beside the Menu No.

•High boost (Hb):

Emphasizes higher audio frequencies; effective for a bassy voice.

•Formant pass (FP):

Improves clarity by suppressing audio frequencies outside the normal voice frequency range.

•Bass boost (bb):

Emphasizes lower audio frequencies; effective for a voice with more high frequency components.

•Conventional (c):

Emphasizes by 3 dB frequencies at 600 Hz and higher.

Note:

◆“U” selectable in Menu No. 50 is not currently available. The menu includes this selection because of a possible future enhancement.

◆The figure above is given for your better comprehension. The actual profiles will be affected by factors such as the receive IF filters.
