Figure 2-2 ORION Screen Display
Refer to Figure 2-2. Next to the 14.250.000
frequency display for VFO A are the letters
TR. ‘T’ is for transmitter, ‘R’ is for main
receiver, and ‘S’ is for sub receiver. As the
operator assigns the transmitter and
receivers using buttons
8
through
13
, the T
R and S indicators will move back and forth
on the screen. If a transmitter or receiver
has no assignment, the annunciator will not
be shown.
The main receiver and the transmitter are
amateur bands-only coverage. An attempt
to assign them to a frequency outside the
ham bands will result in one of three
messages appearing on the screen:
VFO-A OUTSIDE RX RANGE, VFO-B
OUTSIDE RX RANGE or FREQUENCY
NOT SUPPORTED depending on how the
user was attempting to put the main receiver
on a non-amateur frequency.
Buttons
8
and
9
can be used to turn the
transmitter off by deselecting both buttons.
Push
8
and
9
so neither light is lit. The T
indicator will not be present on the screen.
Buttons
12
and
13
can be used in a similar
fashion to deselect the subreceiver, but
there will still be audio present through the
subreceiver audio chain on the last used
subreceiver frequency when doing so – it
will not mute the subreceiver. Subreceiver
audio can be muted by turning the SUB AF
encoder all the way counterclockwise or by
pressing it to mute. After no VFO is
assigned to the subreceiver, the last
subreceiver frequency will still be audible.
The main receiver cannot be disabled; it will
always be assigned to either VFO A or VFO
B via buttons
10
and
11
.
Receivers can be assigned to one VFO or
the other simultaneously. There are
advantages to doing so – see section the
section of Chapter 4 called
DIVERSITY
RECEPTION
for information on diversity
receive capabilities using the two receivers,
the VFO’s and multiple antennas.
(14) MIC
For connection of microphone. Any Ten-Tec
microphone equipped with our 4 pin
connector may be used without modification.
Most dynamic, ceramic, crystal, or electret
microphones also work. When adapting
another microphone, please refer to the
connector-wiring diagram. We include a
spare 4-pin microphone connector (P/N
35057) with the packing kit to allow rewiring
of your current mic for use with ORION.
The pinout for the 4 pin mic connector on
the front of the ORION is shown in Figure
2-3. Wiring of the mic is shown below in
Figure 2-4.
