1. MODE SELECT SWITCH
Selects either side band, USB or LSB, for SSB operation. For FM or CW operation, set the
switch in the desired mode.
2. RIT CONTROL
Shifts the receive frequency +800Hz either side of the transmit frequency. Rotating the
control to the (+) side raises the receiver frequency, and rotating to the (—) side lowers the
receiver frequency. The frequency shift by turning the RIT Control is not indicated on the
frequency display.
If the OFF position is desired, turn the RIT Control completely counterclockwise. (It will
"click" OFF). Then the transmit and the receive frequencies are the same.
3. TUNING CONTROL KNOB
Rotating the TUNING CONTROL KNOB clockwise increases the frequency, while rotating it
counterclockwise decreases the frequency. The frequency is changed іп 100Hz steps in the
SSB and CW modes and in 5KHz steps in the FM mode which correspond to the click-stops.
The smaller vernier marks on the knob each indicate two click-stops and the larger marks
represent ten click-stops.
When tuning up past 145.9999MHz, (145.999MHz When TS Switch is pushed.) the frequency
will automatically revert to 144.000MHz. Likewise, when tuning down past 144.000MHz, the
frequency will automatically revert to 145.9999MHz (145.999MHz).
(ІС-260А : 145.9999MHz and 144.000MHz should be read 148.1999MHz and 143.800MHz.)
4. SCAN START/STOP & MEMORY WRITE (SS/MW) BUTTON
The following three functions are provided by pushing the SS/MW Button.
MEMORY WRITE Writing a frequency into Memory Channel 1, [2], or [3]. *
