The transmit and receive frequency will now be controlled by "A" VFO, but "B" VFO will
follow "А" VFO at the same frequency difference they were set at, so you can return to
DUPLEX operation easily.
RIT (RECEIVER INCREMENTAL TUNING)
By using the RIT circuit, you can shift the receive frequency +1KHz either side of the
transmit frequency without moving the transmit frequency itself. Therefore, when you get a
call slightly off frequency, or when the other station's frequency has shifted, you can tune
in the receiving frequency without disturbing the transmitting frequency. By pushing the
RIT switch down once (it's spring loaded switch) the RIT circuit is turned ON and the RIT
LED is lit. The receive frequency is shifted with the RIT knob.
When the RIT knob is in Ше "0" position, the transmitting and receiving frequencies аге the
same. Rotating the control to the (+) side raises the receiving frequency, and rotating to the
(—) side lowers the frequency. To turn OFF the RIT control, again push the RIT switch
once and the RIT LED will go OFF. When the RIT circuit is OFF, the transmit and receive
frequencies are the same regardless of the setting of the RIT control knob.
When the RIT circuit is ON, if the tuning knob is moved by one increment, the RIT circuit
is automatically pulsed OFF. However, this function can be eliminated by changing the
connecting pins in the driver unit as shown below, in case you would like the RIT to remain
operational when you turn the tuning knob. Or, by continuously depressing the RIT switch
with your finger, while turning the tuning knob, the RIT circuit wil! remain operational
while tuning. |
Other things to remember are: The RIT circuit is operational when the frequency is locked
with the dial lock button. The frequency shifted by turning the RIT control is not indicated
on the frequency display. When the transmitting and receiving frequencies differ by more
than 1KHz, use "A" and "B'' VFOs as outlined previously.
