Product Usage Instructions
OLED Comment Display
All amplifier status indications are explained via detailed text displayed
on the high brightness and contrast OLED display. The upperline’s strip on the
display always reads peak forward power.
No Antenna Tuner Needed
No heavy outboard antenna tuners required for antenna SWR up to 3:1 (and
higher on some bands). Your amplifier will enable you to change antennas
virtually instantaneously and allow you to use your antennas over wider
frequency ranges.
Three Antenna Outputs
Three antenna outputs are selectable using a push button on the front
panel.
Broadband Input Matching
Resulting in a very good load to the transceiver over the entire spectrum
from 1.8 MHz up to 54 MHz.
Less Noise in the Shack
The input bypassing and the vacuum antenna relays are virtually silent even
in the CW QSK mode thanks to specially designed mounting hardware.
Transceiver-Independent
The amplifier operates without special signals from the transceiver. Ground
on TX and 85 W RF drive power are sufficient.
Tube Protection
Permanent monitoring and protection of plate and grid voltages and
currents, reflected power as well as of the exhaust air temperature.
Output RF Arc Protection
An output RF Arc protection is employed. This important feature safeguards
the amplifier, antenna, antenna selector, and tuner against severe damage in
case of possible breakdown.
Continuous Monitoring
Continuous monitoring and/or selectable measurement of the 12 most
important parameters of the amplifier, exciter, and the selected antenna via
OLED display.
Easy Maintenance
Data (service information) regarding amplifier internal status is stored in
a nonvolatile memory for 7 of the most recent auto protection trips.
FAQ

Q: What is the power output of the amplifier?
A: The amplifier has a power output of 1500 W PEP or continuous carrier, with no mode limit. -
Q: How many antenna outputs are available on the amplifier?
A: The amplifier has three selectable antenna outputs using a push button on the front panel.
MAIN FEATURES
EASY TO OPERATE
The plate-load True Resistance Indicator (TRI) is a powerful tuning aid which,
together with the automatically controlled input attenuator, helps the
operator to quickly and precisely match the antenna impedance to the optimum
tube load impedance (5‑10 seconds typically). The AUTO‑OPERATE function (when
enabled) maintains the amplifier in OPERATE mode for you, thus saving manual
operations and time.
USER-FRIENDLY AND DURABLE
An amplifier that is both user‑friendly, and that looks after itself. It is
designed to safely withstand up to 400 W reflected power, up to 100
milliseconds duration of drive spikes, drive RF “tails” after a PTT or KEY
release, operator’s inadvertent tuning errors, etc. The amplifier would also
not cease to function with a “soft” AC mains and would deliver more than half
power at only 85% of nominal mains voltage. It would withstand up to 10
milliseconds (down to zero) voltage drops, and up to +15% line voltage spikes,
which is important particularly when used at Field Days, DXpeditions, and
other portable operating events where emergency power is relied upon.
OLED COMMENT DISPLAY
All amplifier status indications are explained via detailed text displayed on
the high brightness and contrast OLED display. The upper‑line’s strip on the
display always reads peak forward power. LED indicators are provided for
OPERATE mode, attenuation‑on, transmit, selected antenna output, and ON/OFF
conditions.
NO ANTENNA TUNER NEEDED
No heavy outboard antenna tuners required for antenna SWR up to 3:1 (and
higher on some bands). Your amplifier will enable you to change antennas
virtually instantaneously and allow you to use your antennas over wider
frequency ranges.
THREE ANTENNA OUTPUTS
Three antenna outputs are selectable using a push‑ button on the front panel.
BROADBAND INPUT MATCHING
Resulting in a very good load to the transceiver over the entire spectrum from
1.8 MHz up to 54 MHz.
LESS NOISE IN THE SHACK
The input bypassing and the vacuum antenna relays are virtually silent even in
the CW QSK mode thanks to specially designed mounting hardware.
TRANSCEIVER-INDEPENDENT
The amplifier operates without special signals from the transceiver ‑ “Ground
on TX” and 85 W RF drive power are sufficient.
SINGLE TUBE OPERATION
Uses a ceramic and metal radial beam tetrode with plate dissipation of 1000 W
which is specially designed for class AB1 RF linear amplifier operation.
TUBE PROTECTION
Permanent monitoring and protection of plate and grid voltages and currents,
reflected power as well as of the exhaust air temperature.
OUTPUT RF ARC PROTECTION
An output RF Arc protection is employed. This important feature safeguards the
amplifier, antenna, antenna selector, and tuner against severe damage in case
of possible breakdown.
CONTINUOUS MONITORING
Continuous monitoring and/or selectable measurement of the 12 most important
parameters of the amplifier, exciter, and the selected antenna via OLED
display.
