1. POWER/SWR METER Dual
needle meter displays FORWARD and
REFLECTED power in watts. SWR is meas-
ured where the two needles intersect on
the red scale.
2. PEAK AND PEAK/HOLD Active
circuitry is used to offer peak reading for
SSB. This peak feature is also translated to
provide an approximate 2 second hold at
the peak level for easy viewing. NOTE: The
peak/hold will function only if the PEAK
button is depressed in as well.
3. RANGE The power range is 300 watts
on low and 3000 watts on high (push button
in for high).
4. FAN In position turns on fan which
cools the internal components of the tuner
when using a service that requires constant
carrier operation (for e.g. AM or RTTY)
5. BALANCED/COAX Selects either
coax feed or balanced feed. A LED shows
when balanced mode is selected.
6. POWER ON A two position button
(red) selects whether the meter is illumi-
nated also this provides power to the relay
and the peak and peak/hold circuits.
7. INDUCTOR 28 µH continuously vari-
able ceramic roller inductor driven by a
crank handle. Coupled to the crank handle
is a gear-driven precision mechanical
counter.
8. OUTPUT Continuously adjustable
output capacitor. Min. capacitance=0. Max
capacitance = 100.
9. DIRECT-TUNED MODE SWITCH
Six-position rotary switch selects an output
coaxial connector.
a. DIRECT BYPASS selects BYPASS COAX connec-
tor bypassing the impedance matching circuit but
providing SWR, FORWARD and REFLECTED
power meter readings.
b. DIRECT COAX 1 selects COAX 1 connector
bypassing the tuner matching circuit but providing
SWR, FORWARD and REFLECTED meter readings.
c. DIRECT COAX 2 selects COAX 2 connector
bypassing the tuner matching circuit but providing
SWR, FORWARD and REFLECTED meter readings.
d. TUNED COAX 1 selects COAX 1 connector
through the impedance matching T circuit.
e. TUNED COAX 2 selects COAX 2 connector
through the impedance matching T circuit.
f. TUNED WIRE/BAL selects the END FED WIRE
connector through the impedance matching circuit.
For balanced antennas, the balanced coax switch
must be IN.
10. INPUT Continuously adjustable input
capacitor. Min. capacitance = 0. Max = 100.
