■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.
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.

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.
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.

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

•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.
