Phones - Ten-Tec ORION II Manual

(15) PHONES

The PHONES jack is optimally for stereo
headphones. ORION II uses left and right
stereo outputs from two audio amps. A
mono plug will short-circuit one of the two
audio channels unless wired and used as
described below. Use a stereo (3-circuit)
plug such as one that comes packed with
your radio. Using stereo headphones lets
you take full advantage of ORION II's
advanced features.
Audio from the front panel phones jack to a
stereo connector is left = tip, right = ring,
ground = sleeve.
Mono headphones can be used with ORION
II, provided they are wired correctly with a
stereo plug and the headphone audio
settings in the AUDIO menu are set to the
appropriate values. You can use left side
audio output to mono headphones by wiring
the headphones as shown in Figure 2-5.
See (36) AUDIO later in the manual for
adjusting the headphone output for mono
headphones as wired below.

(16) CW
ORION II has two jacks for keying the
transceiver in CW mode. The front panel
provides a ¼" stereo jack for connection of
an external key, keyer, or paddles. See
Figure 2-6 for proper wiring. The rear panel
has a 1/8" stereo jack connected in parallel
(see description of (79) KEY later in the
manual). ORION II on initial power-up has
its internal keyer disabled. To use the
internal keyer in a CW mode, press the SP

button ('Speed') and then rotate the MULTI
knob for an appropriate CW speed (Note: In
SSB modes, SP is used for speech
processing and displays a different value).

Keyer
The PTT pin (3) on the AUX I/O rear jack or
the PTT connection on the microphone jack
may allow you to connect an independent
keyer or computer to share CW keying
depending on how this jack has been
configured via the menu system.
This would be useful if using the output of a
computer program (like contest logging
software) while also desiring a paddle to be
connected to the radio for using the internal
keyer. Connect the CW keying output of the
computer logging program to PTT pin (3) on
the AUX I/O jack or the microphone jack,
and then connect your paddle to either of
the two panel mounted CW jacks, front or
rear. See the description of item PTT in
CW as in the manual section for (CW) CW
MENU in Chapter 3 and EXTERNAL CW
OUTPUT PLUS CW KEYER OPERATION
FROM PADDLES in Chapter 4.
