■ Fine Tuning

The default step value when turning the Tuning

control to change the frequency is 10 Hz for SSB,

CW, and FSK modes, and 100 Hz for FM and AM

modes. However, you can change the step size to

1 Hz for SSB, CW, and FSK modes, and 10 Hz for

FM and AM modes.

1 Press [9/ FINE/STEP].

• “FINE” appears.

2 Turn the Tuning control to select the exact

frequency.

3 To quit the function, press [9/ FINE/STEP]

again.

• “FINE” disappears.

Note:

◆

Fine Tuning works only on the main transceiver.

◆

If Menu No. 03 is ON, you cannot perform fine tuning in FM

mode for all bands and AM mode for the 144 MHz/

430/ 440 MHz/ 1.2 GHz (TS-2000 optional) bands.

■ Equalizing VFO Frequencies (A=B)

This function allows you to copy the frequency and

modulation mode of the active VFO to the inactive

VFO.

1 Select the frequency and mode on VFO A or

VFO B.

2 Press [A=B].

• The frequency and mode selected in step 1

are copied to the inactive VFO.

3 Press [A/B] to confirm that the frequency was

copied.

RIT (RECEIVE INCREMENTAL TUNING)

RIT provides the ability to change your receive

frequency by ±20.00 kHz in steps of 10 Hz without

changing your transmit frequency. If the Fine Tuning

([9/ FINE/STEP]) function is ON, the step size

becomes 1 Hz. RIT works equally well with all

modulation modes and while using VFO or Memory

Recall mode.

1 Press [RIT/ CW TUNE].

• “RIT” and the RIT offset appear.

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

to 0.

3 Turn the RIT/ SUB control to change your receive

frequency.

4 To turn off RIT, press [RIT/ CW TUNE].

• The receive frequency is returned to the

frequency that was selected prior to step 1.

Note:

◆

RIT works only on the main transceiver.

◆

When storing the frequency in a Memory channel with RIT

function ON, RIT offset frequency is added or subtracted to/ from

the VFO frequency. Then the calculated data is stored in the

Memory channel.

AGC (AUTOMATIC GAIN CONTROL)

When using a mode 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

Unlike other transceivers, the TS-2000’s digital AGC

circuit allows you to adjust the time constant from

slow to fast in 20 steps, where 1 is the slowest and

20 is the fastest. Furthermore, you can switch the

AGC OFF if you desire.

For your convenience, the following default AGC time

constant has already been programmed.

SSB: Level 7 CW: Level 12

FSK: Level 14 AM: Level 5

To change the default time constant:

1 Press [8/ AGC/OFF].

• The AGC time constant scale appears on the

sub dot-matrix display.

2 To select a slower time constant, turn the

MULTI/ CH control counterclockwise. The bar

indicator moves from F(ast) to S(low). To select

a faster time constant, turn the MULTI/ CH

control clockwise. The bar indicator moves from

S(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.
