ACCESSORY CONNECTION EXAMPLES

BASIC TRANSCEIVE OPERATION

Refer back to the operating instructions in
Chapter 2 for (8 – 13) VFO ASSIGNMENTS.
The most important point to consider is that
VFO's are not receivers. Both receivers can
be assigned to one VFO if desired.
Typical transceive operation would be to
have the main receiver and the transmitter
on VFO A, and the subreceiver on VFO B.
To do so, press buttons as shown below in
Figure 4-1. Under VFO A, the buttons next
to TX and RX are lit, under VFO B the SUB
RX button is lit.
Figure 4-1. VFO selection for transceive with
main RX/TX on VFO A, subreceiver VFO B.
VFO A is always the main tuning knob
closest to the screen – VFO B is always the
main tuning knob at the far right of the
ORION.
Turn the MAIN AF knob to increase main
receiver volume. Turn the SUB AF knob to
increase sub receiver volume. Either of
these can be muted by pressing the encoder
towards the radio face. To unmute, press or
turn the knob.
The AUDIO menu determines the mix of
main receiver and sub receiver audio heard
through the speaker or the headphones.
See the Chapter 2 description for (36)
AUDIO.
Antenna selection is determined by the
matrix of six buttons at the far left of the

Chapter 2 under (2 –7) ANTENNA
ASSIGNMENTS.

OPERATING SPLIT FREQUENCY

Often DX stations will be listening on one
frequency while transmitting on another.
The two receivers and two VFO's in ORION
permit the operator to listen to both the DX
stations frequency and the frequency where
the DX station is listening for calls
simultaneously. There is no SPLIT button,
but setting up split frequency operation only
requires pressing the A>B button as shown
below.
An example using the typical transceive
setup of main RX/TX on VFO A and
subreceiver on VFO B: A DX station is
transmitting on 14.195 MHz and listening for
calls on 14.210 MHz. Tune in the DX station
on 14.195 on VFO A. Press A>B to
equalize the frequencies on the two VFO's.
Tune VFO A to 14.210. You are now
listening to the DX station on the
subreceiver on VFO B on 14.195 and are
ready to transmit (and listen) on 14.210
using the main receiver.
For weak DX stations operating split
frequency, it is probably advantageous to
use the main receiver for listening to the DX
station and using the subreceiver frequency
for monitoring the pileup and your transmit
frequency. Starting from the same example
of main RX/TX on VFO A and subreceiver
on VFO B, DX station on 14.195 listening on
14.210: Tune in the DX station on 14.195
on VFO A. Press A>B to equalize the
frequencies on the two VFO's. Tune VFO B
to 14.210. Press the button next to TX,
under VFO B. You are now listening to the
DX station on the main receiver on 14.195
on VFO A, and are listening and ready to
transmit on 14.210 with the subreceiver and
transmitter on VFO B. See Figure 4-2 for
assignment of VFO buttons.
