Tune; Alc; Bargraph - Ten-Tec ORION II Manual

(40) TUNE

The TUNE button, when pressed, will
transmit a CW carrier at approximately 20
watts output power to allow either the
internal automatic antenna tuner to tune (if
installed) or for user adjustment of an
external antenna tuner or linear amplifier.
It may be desirable to have keydown CW
carrier output at the power output level set
by using the PWR control (button 17). To do
so, press the PWR button immediately after
pushing the TUNE button. Power output will
move from the low power setting to
whatever level the PWR control has been
set at with the MULTI knob. Repeat
operation will require pushing TUNE then
PWR again for the higher output value.

ALC

The ALC light just to the right of the S-meter
is used to indicate when automatic level
control action for the set output of the radio
has been reached. It will flash on and off
with all CW characters transmitted. On
SSB, the ALC light should light on voice
peaks to indicate proper adjustment of
microphone gain.
At very low power outputs, the ALC light will
be lit continuously when transmitting in SSB
modes. This is normal.

BARGRAPH

A bargraph meter appears on the ORION
screen immediately to the right of the VFO B
frequency display. This un-scaled meter is
used as a signal strength reference for the
subreceiver, but no s-unit value is indicated.
Additionally, appearing above the bargraph
is a display of SWR while transmitting. SWR
