FOR EXAMPLE:
Set the VFO GANG Switch to the "SEP" position and set "A" VFO to 145.725.0MHz and "B"
VFO to 145.025.0MHz. Then set the VFO GANG Switch to the "GANG" position, and the VFO/
MEMORY Switch to the "RA-TB" position. 145.725.0 will be shown on the readout during
receive ("А" VFO) and 145.025.0 during transmit ("В" VFO). You are now receiving on
145.725.0MHz and transmitting on 145.025.0MHz, so you can access a 700KHz separation
145.025/145.725 repeater.
If you change the receiving ("A" VFO) frequency, the transmitting ("B'" VFO) frequency will
follow the receiving frequency at the same frequency difference. So, #751, set "А" VFO and
"B" VFO at the frequencies for repeater input/output frequency separation. This makes repeater
operation simple.
. FOR EXAMPLE:
'If you change the receiving frequency from 145.725MHz to 145.875MHz, the transmitting fre-
quency will change from 145.025MHz to 145.175MHz, so now you can access an 145.175/
"145.875 repeater.
Setting the VFO/MEMORY Switch to "ВВ-ТА" reverses the above.
When you want to change to the SIMPLEX mode from DUPLEX operation, set the VFO/
MEMORY Switch to the A or B position.
If you set the VFO GANG Switch to "GANG" position, the transmit and receive frequency will
now be controlled by "A" VFO or "В" VFO, but the other VFO will follow the selected 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 +800Hz 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.
When the RIT knob is in the center (12 o'clock) position, the transmitting and receiving fre-
quencies are 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, turn the knob
completely counterclockwise to the OFF position. (It will "click" OFF.)
When the RIT circuit is OFF, the transmit and receive frequencies are the same.
Other things to remember are: 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
800Hz, use "А" and "B" МЕО" as outlined previously.
