counter-clockwise will decrease the frequency in 100Hz steps in the USB, LSB and CW
modes and in 5KHz steps in the FM mode.
NOTE: Rotating the knob counter-clockwise immediately after applying power will jump
to the highest frequency 147.995MHz and will decrease the frequency in 5KHz
steps.
ІШ Switching from one VFO to the other МЕ О does not clear the first VFO. The frequency
is retained in the VFQ's memory.
FOR EXAMPLE:
lf 144.125.0MHz is set with "A" VFO, and the VFO switch is set to "B" VFO, the fre-
quency LED readout will show "В" VFO's frequency, but 144.125.0MHz is still stored in
"А" VFO's memory. Returning the VFO switch to "A" VFO position, and 144.125.0 will
be displayed on the readout. Accordingly, if the switch is placed іп the "B" VFO position,
the frequency that was set with the "В" VFO will appear. This allows you to set a certain
frequency with one VFO, work up and down the band with the other VFO, and periodically
check the set frequency simply by switching between "А" and "B" VFO. It also allows you
to search for a clear frequency with one VFO, while keeping your operating frequency on
the other VFO. When you have found a clear frequency, switch back to your operating
frequency, inform the station you are in contact with of the new frequency, and switch back.
It's that simple!
When recalling a memorized frequency be sure to turn OFF the dial fast circuit. If the
circuit is not turned OFF, the memorized frequency's 1KHz and 100Hz digits will both.
revert to "0".
N-DUP/R-DUP
These positions will allow you to operate a repeater or split transmit/receive frequencies.
FOR EXAMPLE: |
Set "A" VFO to 146.940.0MHz and "B" VFO to 146.340.0MHz. Then set the VFO select
switch to the N-DUP position. 146.940.0MHz will shown on the readout during receive
("A" VFO) and 146.340.0MHz during transmit ("B" VFO). You are now receiving on
146.940.0MHz and transmitting on 146.340.0MHz, so you can access а 146.34/146.94
repeater.
If you change the receiving ("A" VFO) frequency, the transmitting ("В VFO) frequency
will follow the receiving frequency at the same frequency difference. So, first, set "A" VFO
and "B" МЕО at the frequencies for repeater input/output frequency separation. This
makes repeater operation simple.
FOR EXAMPLE: |
If you change the receiving frequency from 146.94MHz to 146.88MHz, the transmitting
frequency will change from 146.34MHz to 146.28MHz, so now you can access a 146.28/
146.88 repeater.
Setting the VFO select switch to R-DUP reverses the above.
When you want to change to the SIMPLEX mode from DUPLEX operation, set the VFO
select switch to the SIM position.
