The default frequency step size when turning the
Tuning control to change the frequency is 10
Hz for SSB/ CW/ FSK, and 100 Hz for AM/ FM.
However, you can change the frequency step size
to 1 Hz for SSB/ CW/ FSK, and 10 Hz for AM/ FM.

The default Tuning control adjustment rate is 500.
This represents the number of pulses the Tuning
control generates in a complete revolution. Each
pulse changes the tuning frequency based on the
current frequency step size (the frequency step
size for the Tuning control is 10 Hz for SSB/ CW/
FSK and 100 Hz for AM/ FM). For example, in
SSB mode the frequency step size is 10 Hz, so the
frequency would change by 5,000 Hz in a complete
revolution of the Tuning control. The adjustment
rate of the Tuning control can be lowered to 250
pulses per revolution or increased to 1000 pulses
per revolution.

RIT provides the ability to change your reception
frequency by ±9.99 kHz in steps of 10 Hz without
changing your transmission frequency. If the Fine

frequency step size becomes 1 Hz (±9.999 kHz). RIT
works equally well with all modulation modes and

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:
