Sets the LINE OUT level. LINE OUT connections go to PC soundcard inputs.
Settings above 10 may result in overdrive of the soundcard or saturation of the

Note :
Normally,
LIN OUT
sets a fixed-level receive-only output for main/sub
(L/R), compatible with digital modes. T apping

switches
LIN OUT
to
=PHO NES
, where the line outputs match headphone audio, audio level is
controlled by AF/SUB gain controls, and both RX and T X audio are available.

microphones. Mic FUNCT ION button not presently supported.
Tapping
UP or DOWN once will move the VFO up or down one step (based on
the current tuning rate);
holding
UP or DOWN will move up or down
continuously. If you see the frequency moving up or down continuously, your mic
is not compatible, and
MIC BTN
must be set to
O FF
.
NB SA VE
NO
Set to
YE S
to save noise blanker on/off state per-band. Noise blanker levels, both
DSP and I.F., are always saved per-band regardless of this setting.
PA TEMP
N/A
If a KPA3 (100-W PA module) is installed, shows KPA3 heatsink temperature
and allows it to be adjusted. See calibration procedure on pg. 50.

PTT RLS
20
(Advance d)
Provides a delay between release of PTT and dropping of the
transmit carrier; intended for use with fast turn-around data protocols such as
AMT OR and PacT OR. (No effect in CW, FSK D, or PSK D modes.)
A value of 20 or higher may be needed to ensure accurate data transmission with
these protocols. If sync data or
–
S
is in effect (see
SYNC DT
), a lower value,
typically 10 to 12, is optimal. Also see AMT OR/PacT OR (pg. 32).
PWR SET
NOR
If set to
NO R
, the power level on each band follows the present setting of the
PWR control. If set to
P E R-BAND
, the power level is saved on each band. This
is especially useful with external amplifiers that have varying per-band gain, as
well as with transverters.
