(8) 2-Position Pushbutton Switches
VOX: enables automatic voice-actuated
transmit/receive switching in SSB, AM and
FM modes; semi break-in keying in CW mode;
and tone-actuated transmit/receive swit-
ching in FSK mode. This button must be
pressed together with the Full BK-IN but-
ton for QSK operation.
FULL BK-IN: activates full break-in CW
(QSK) on the hf bands. When activated,
the receiver will be audíble between dits
and dahs. The VOX button must be depres-
sed for this switch to function.
PROC: enables the rf speech processor in
SSB and AM modes. Processing level is set
by the control with the same name,
MONI: enables the CW sidetone monitor in
CW mode, and the transmit (IF) monitor in
other modes. Volume is set by the control
with the same name,
TX SHIFT: enables custom setting of the
transmitter IF bandpass in SSB modes,
using the control of the same name.
T ENC: activates either the Burst Tone
generator (when the FTE-2 Burst Unit is
installed), or the CTCSS (subaudible) tone
generator on FM transmissions when the
optional FTS-8 Tone Squelch Unit is
installed.
NAR: selects narrow IF filtering in CW
and AM modes. Narrow AM -6dB bandwidth is
2.7 kHz, and narrow CW is 600 Hz.
RF AMP: activates the receiver front-end
RF amplifier for extra sensitivity on HF
bands, when needed.
ATT: adds a 20dB attenuator between the
antenna and the receiver front end for
extra immunity to overload on the HF
bands, when needed. The 'ATT' indicator
LED below the display window is lit when
this button is depressed.
(9) Pushbuttons with LED Indicators
D LOCK (with red LED): disables the
tuning knob to prevent inadvertent fre-
quency changes.
MUTE (with yellow LED): disables receiver
audio, for keeping the receiver on in
standby.
NB (with green LED): activates the noise
blanker.
APF (with green LED): activates the audio
peak filter (for CW reception).
NOTCH (with green LED): activates the IF
notch filter.
(10) Tuning Knob
Controls displayed frequency in selectable 10
Hz or 100 Hz steps.
(11) VDOWN A UP PROGRAM Keys
Tune displayed frequency in programmable
steps, which may be different for each mode.
Pressing and holding one of these keys for
more than one half second activates multiple
stepping in the programmed steps. Steps are
originally preset at the factory to 5 kHz for
all modes.
(12) SHIFT -S TONE
The inner SHIFT control allows the center of
the receiver IF passband to be positioned
above or below that of the received signal, to
eliminate interference from signals on adja-
cent frequencies. Normal setting is the 12
o'clock position.
The outer TONE control adjusts receiver audio
characteristics in all modes.
(13) BAND / MCH Keys
Use thes keys to select operating frequency
band or memory channel (according to the oper-
ating status selected by the keypad). The key
on the left steps down, and the key on the
right steps up. Press and hold for a half
second for multiple stepping. In General Cov-
erage mode, steps are 500 kHz. In Ham mode,
steps are in 500 kHz ham band segments. If
the FTS-8 Tone Squelch Unit is installed,
these keys also select tone frequency.
(14) NOTCH -S-APF
The inner NOTCH control adjusts the frequency
of the IF notch within the receiver passband
when the NOTCH button is depressed, except in
the FM mode.
The outer APF (Audio Peak Filter) control ad-
justs the frequency of the filter passband
during CW operation when the APF button is
depressed.
