389 COMMUNICATING AIDSn Fine TuningThe default step value when turning the Tuningcontrol to change the frequency is 10 Hz for SSB,CW, and FSK modes, and 100 Hz for FM and AMmodes. However, you can change the step size to1 Hz for SSB, CW, and FSK modes, and 10 Hz forFM and AM modes.1 Press [9/ FINE/STEP].• “FINE” appears.2 Turn the Tuning control to select the exactfrequency.3 To quit the function, press [9/ FINE/STEP]again.• “FINE” disappears.Note:uFine Tuning works only on the main transceiver.uIf Menu No. 03 is ON, you cannot perform fine tuning in FMmode for all bands and AM mode for the 144 MHz/430/ 440 MHz/ 1.2 GHz (TS-2000 optional) bands.n Equalizing VFO Frequencies (A=B)This function allows you to copy the frequency andmodulation mode of the active VFO to the inactiveVFO.1 Select the frequency and mode on VFO A orVFO B.2 Press [A=B].• The frequency and mode selected in step 1are copied to the inactive VFO.3 Press [A/B] to confirm that the frequency wascopied.RIT (RECEIVE INCREMENTAL TUNING)RIT provides the ability to change your receivefrequency by ±20.00 kHz in steps of 10 Hz withoutchanging your transmit frequency. If the Fine Tuning([9/ FINE/STEP]) function is ON, the step sizebecomes 1 Hz. RIT works equally well with allmodulation modes and while using VFO or MemoryRecall mode.1 Press [RIT/ CW TUNE].• “RIT” and the RIT offset appear.2 If required, press [CLEAR] to reset the RIT offsetto 0.3 Turn the RIT/ SUB control to change your receivefrequency.4 To turn off RIT, press [RIT/ CW TUNE].• The receive frequency is returned to thefrequency that was selected prior to step 1.Note:uRIT works only on the main transceiver.uWhen storing the frequency in a Memory channel with RITfunction ON, RIT offset frequency is added or subtracted to/ fromthe VFO frequency. Then the calculated data is stored in theMemory channel.AGC (AUTOMATIC GAIN CONTROL)When using a mode other than FM, AGC selects thetime constant for the automatic gain control circuit.Selecting a slow time constant will cause the receivergain and S-meter readings to react slowly to largeinput changes. A fast time constant causes thereceiver gain and the S-meter to react quickly tochanges in the input signal. A fast AGC setting isparticularly useful in the following situations:• Tuning rapidly• Receiving weak signals• Receiving high-speed CWUnlike other transceivers, the TS-2000’s digital AGCcircuit allows you to adjust the time constant fromslow to fast in 20 steps, where 1 is the slowest and20 is the fastest. Furthermore, you can switch theAGC OFF if you desire.For your convenience, the following default AGC timeconstant has already been programmed.SSB: Level 7 CW: Level 12FSK: Level 14 AM: Level 5To change the default time constant:1 Press [8/ AGC/OFF].• The AGC time constant scale appears on thesub dot-matrix display.2 To select a slower time constant, turn theMULTI/ CH control counterclockwise. The barindicator moves from F(ast) to S(low). To selecta faster time constant, turn the MULTI/ CHcontrol clockwise. The bar indicator moves fromS(low) to F(ast).3 If you want to turn the AGC OFF, press [FUNC],[8/ AGC/OFF].Note: You cannot adjust the AGC time constant on the sub-receiver.
