1. POWER/SWR METER
Dual needle
meter displays FORWARD and RE-
FLECTED power in watts. SWR is meas-
ured where the two needles intersect on
the red scale.
2. PEAK HOLD
Select to read Peak Hold
on the SWR meter.
3. PEAK
Selects between PEAK and AVER-
AGE Power metering display.
4. RANGE
Two-position switch selects the
range of FORWARD and REFLECTED
power displayed on the power meter.
When the RANGE button is OUT, the
FORWARD meter scale reads 300 watts
full scale and the REFLECTED meter scale
reads 60 watts full scale. When the RANGE
button is IN, the FORWARD meter scale
reads 3000 watts full scale and the RE-
FLECTED meter scale reads 600 watts full
scale.
5. POWER
Select to turn on the backlight
in the meter and enable Peak, Peak Hold,
and 160 Meter functions. The jack on the
back panel must be supplied with 12 VDC
for this to function.
6. INDUCTOR
15
µ
H continuously vari-
able ceramic roller inductor driven by a
crank handle. Coupled to the crank handle
is a gear-driven precision mechanical
counter.
7. TUNE
Continuously adjustable
differential capacitor.
8. 160 METER SWITCH
Pushing this
button to the IN position switches in extra
inductance for the 160 Meter Band. The
button should be in the OUT position for
use on all other bands — 80 through 6
Meters.
9. DIRECT-TUNED MODE SWITCH
Six-position rotary switch selects an output
coaxial connector with direct mode which
bypasses the tuner and tuned position
which passes antenna through the tuner
components.
a. DIRECT BYPASS selects BYPASS COAX
connector, bypassing the impedance matching
circuit but providing SWR, FORWARD and RE-
FLECTED meter readings.
b. DIRECT COAX 1 selects COAX 1 connec-
tor, bypassing the tuner matching circuit but
providing SWR, FORWARD and REFLECTED
meter readings.
c. DIRECT COAX 2 selects COAX 2 connec-
tor, bypassing the tuner matching circuit but
providing SWR, FORWARD and REFLECTED
meter readings.
d. TUNED COAX 1 selects COAX 1 connec-
tor through the impedance matching T circuit.
e. TUNED COAX 2 selects COAX 2 connec-
tor through the tuner matching T circuit.
f. BALANCED OUT selects the balanced and
End Fed Wire output connectors located after the
impedance matching circuit.
