Operating instructions

The VC-300D Antenna Tuner is the top of the line!
This tuner has the same identical features and specs
as the VC-300D but includes a Digital Bargraph
Display which enables the user the capability of read-
ing Peak Output Power. Level and Delay controls have
been added to calibrate the display and to vary the
delay response.
FEATURES:
Versatility: The VC-300D is compatible with almost
ANY antenna; including verticals, dipoles, inverted
vees, beams or mobile whips that are fed by coax
cable, open feeders, balanced lines or a single wire.
Tuning Options: The VC-300D features a front
panel switch control which allows you to alternate
between two coax fed antennas (direct or through the
tuner). You can also switch to a balanced line or a
wire antenna. The BYPASS position allows you to
switch to a directly connected coax antenna. In the
DIRECT positions, COAX 1 OUT or COAX 2 OUT, the
tuner is bypassed but the SWR/Power Meter remains
active. The VC-300D also has switch positions for the
Dummy Load (TUNED or DIRECT). Using the TUNED
Dummy Load allows you to preset the tuner for the
band in use, eliminating on-air interference.
Dual Movement Meter: The VC-300D features a
dual movement meter which simultaneously monitors
Power and SWR. The meter is lighted. 115 VAC to 12
VDC adaptor is included.
Bar Graph Display: 20 segment LED display indicates
100% peak reading with adjustable level and delay.
SPECIFICATIONS:
RF Power: 1.8 to 30 MHz, continuous 200 Watts;
150 Watts @1.8 MHz. (max SWR 4:1)
XMTR/Antenna
Tuning: Continuous Rotation Capacitors, 48
Position Switched Inductor.
Selector: Six Positions: COAX1 (tuned and
direct), COAX 2 (tuned and direct),
BYPASS, and Balanced Antenna.
PWR Switch: High and Low (300W/30W).
Dimensions: 10.2Wx9.4Dx3.5H inches.
Weight: 3.4 lbs.
The HFT-1500 Antenna Tuner optimizes the performance
of your antenna system from your transmitter or SWL receiv-
er by providing adjustable impedance matching. HFT-1500
measures the power and the Standing Wave Ratio, which
allows you to tune the indicated SWR to the lowest ratio pos-
sible for the selected transmit frequency. HFT-1500 features
a precision frequency compensated dual movement SWR
meter. Included with the tuner is a unique Digital Bar Graph
Display that enables you to analyze peak SSB power meas-
urements. Level/Delay controls are front panel adjustable.
SPECIFICATIONS AND FEATURES:
Front Panel Indicators:
Meter: Dual movement lighted cross-needle power
and SWR meter. RF directional coupler sensing head
for the internal wattmeter circuit. 115 VAC to 12 VDC
adaptor is included.
Bar Graph Display: 21 segment LED display to indicate
100% peak reading with adjustable level and delay.
Front Panel Controls:
Input Tuning: Continuous rotation 4.5 kV capacitor.

Inductance: 28 uH roller inductor with #10 bright tin
plated wire and Delrin/Teflon body.
Antenna Switch Selector: 6 position ceramic coax
switch: COAX1 Tuned/Tuner Bypass, COAX2 Tuned/
Tuner Bypass, Bypass and Balanced Antenna.
Power Range Switch: 2 position: 300W/3000W.
