(8 - 13) Vfo Assignments - Ten-Tec ORION II Manual

One antenna + one receiver, two antennas +
two receivers, One antenna + 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 II 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.
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 a
default screen when powering up ORION
after a master reset.

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.
