connected antennas to each of the two
receivers.
The most common arrangement would be to
have a single antenna connected to ANT 1
used by either the main receiver only, or by
the main receiver and the subreceiver both.
Buttons
2
,
4
and
6
, as shown above, allow
ANT 1, ANT 2 or RX ANT to be connected
to the main receiver.
To connect an antenna attached to the
transceiver via the ANT 1 rear panel jack to
the main receiver, press button
2
shown
above. The amber LED embedded in the
button will light, indicating the main receiver
is now connected to ANT 1.
Pressing button
4
as shown above will
connect the main receiver to ANT 2.
When either of the ANT 1 or ANT 2 buttons
in the MAIN RX/TX column is lit, a receive
only antenna can be substituted for the
receive side of ANT 1 or ANT 2 by pushing
button
6
as shown in Figure 2-1.
Example: With button
2
or button
4
lit, press
button
6
. The operator will note that there
are now two lighted buttons in this column,
either of
2
or
4
, plus
6
. The radio will
automatically use either ANT 1 or ANT 2 for
transmit and RX ANT for receive in this
configuration.
Buttons
3
,
5
, and
7
control the assignment
of the subreceiver to each of the antennas
connected to the radio. The subreceiver can
either share the same antenna in use for the
main receiver, or it can be split off to used
with a separate antenna.
An antenna attached to ANT 1, ANT 2, or
RX ANT can be used simultaneously with
both receivers or they can be split off to
separate receivers. One receiver cannot be
used with two antennas at the same time.
One a one receiver, two an
two receivers, One a two receivers
are the available selections.
Additionally, button
2
is used for performing
a master reset of the transceiver. See the
MASTER RESET
description in Chapter 4.
(8 – 13) VFO ASSIGNMENTS
While dual receive transceivers are common
today, ORION allows an unprecedented
level of flexibility to the operator for main
and subreceiver control with the VFO
assignment buttons. Receivers can be
assigned to separate VFO’s (the most
common arrangement) or both receivers can
be assigned to a single VFO.
Important note: VFO’s are not receivers!
The operator is permitted to assign each
VFO to either receiver and the transmitter.
VFO’s can be adjusted even if NO receiver
is selected for them.
The two large tuning knobs are for each
VFO. The large knob on the left closest to
the display screen is always VFO A, the
large knob to the right is always VFO B.
Buttons
8
and
9
determine which VFO the
transmitter is assigned to. The TX
frequency also determines the output of the
BAND DATA connectors on the ORION rear
panel (see description of
76
BAND DATA 1
and
77
BAND DATA 2 elsewhere in this
manual).
Buttons
10
and
11
determine which VFO the
main receiver is assigned to.
Buttons
12
and
13
determine which VFO the
sub receiver is assigned to.
The assignments of the VFO’s are not only
shown by the amber LED’s inside the
buttons, and are announced on the display
screen. Shown in Figure 2-2 below is the
default screen when powering up ORION
after a master reset.
