(69) TX OUT 2 / TX EN 2
TX OUT 2 and TX EN 2 are used for a full
break-in linear amp using ANT 2.
TX OUT and TX EN should be connected to
the corresponding QSK loop IN and OUT
jacks on your amp. On a Ten-Tec QSK
amp, TX OUT is connected to KEY IN and
TX EN is connected to KEY OUT via
shielded cables (consult the operator's
manual of your non-Ten-Tec QSK amp for
the proper loop information).
To use the full break-in keying loop, it must
be enabled from the MENUS. The keying
loop is turned on and off via the TX
submenu in the MENUS. Note: If the loop is
turned on, and no connections are made it
will prevent the ORION II from transmitting
on ANT 2.
See Chapter 4 for a complete description on
interfacing a linear to the ORION II.
TX EN can also act as a transmit inhibit
input if it is desirable to prevent ORION II
from transmitting until other station
accessories have been switched. Example:
The last item keyed from a sequencer used
for VHF transverter operation. To use the
loop in this manner, turn the keying loop on
in the MENUS. Connect the inhibit line to
the TX EN jack. The ORION II will not
transmit until a closure to ground appears at
the TX EN jack.
(70) +13.8 VDC
This jack provides +13.8 Vdc for connection
of accessory equipment. A maximum of 2
amps current draw is possible. The jack is
equipped with a thermal shut-off, autoreset 2
ampere fuse. The jack has voltage present
only when transceiver power is turned on.
Connection of more than one accessory
item (i.e. the optional #310 fan kit plus
another accessory) via a "Y" cable may
cause ground loop problems. See manual
section titled TROUBLESHOOTING.
(71) AUX RX
This RCA-style phono connector is for
connection of a receive only antenna. This
antenna can be used to transceive with
either ANT 1 or ANT 2 being used as the
transmit antenna, merely by selecting the
appropriate button on the front panel (see
566 manual
Part #74410
Printed in USA
description of buttons 2 through 7 on the
front of the radio).
(72) XVRT KEY and (73) XVTR RF
XVRT KEY is transmit keyline for external
transverter. Connect this jack to the keyline
of your transverter unit. The capabilities and
precautions for this circuit are the same as
for the AMP 1 KEY circuit described above.
XVTR RF provides a low-level TX RF output
for external transverter. The RF output level
is ALC-controlled at approximately +15 dBm
- this is adjustable from +5 to +15 dBm by
using the PWR and MULTI control when the
transverter output has been activated in the
MENUS. Both transverter support
connections are activated via the TX menu.
See Chapter 4 for complete information and
diagrams on connecting a VHF or UHF
transverter to ORION II.
(74) LINE OUT
This is a line level output. What is present
at this jack is determined by the Line Out
Source item in the Other: menu. Line level
audio from the main, sub, or both receivers
can be routed via this jack. There are three
selectable output level of High, Med, Low
that are selected in the Other: menu under
line item Line Out Level. 'High' is
approximately 1 V p-p output, 'Med' is
approximately .5 V p-p output, 'Low' is
approximately .25 V p-p output. Impedance
600 ohms. 1 V p-p at 600 ohms (the 'High'
setting) is typically the line level utilized by
most equipment requiring a line level input
signal. Please note there are also fixed 1 V
p-p 600 ohm line level outputs for main and
sub receiver audio, as determined by the
AUDIO menu available on the AUX I/O
connector on the rear panel.
(75) SPARE
This is an open jack provided for future use
or for custom modifications made by the
user.
(76) BAND DATA 1 and
(77) BAND DATA 2
These are 15-pin receptacles used for
switching accessory devices. BAND DATA
1 corresponds to ANT 1 and AMP KEY 1 or
TX OUT / TX EN 1. BAND DATA 2
corresponds to ANT 2 and AMP KEY 2 or
TX OUT / TX EN 2. They contain open-
