Easy to operate
The TRI is a powerful tuning aid that, 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 the OPERATE mode for you, thus avoiding unnecessary manual operations.
No antenna tuners
No heavy outboard antenna tuners required for antenna
VSWRs up to about 3:1. Your amplifier will enable you to change antennas virtually instantaneously and allow you to use your antennas over wider frequency ranges.
An amplifier that is both user-friendly and that looks
after itself. It is designed to safely withstand up to 300W 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 also will not cease to function with a “soft” AC mains and will deliver more than half power at only 85% of nominal mains voltage. It can withstand voltage drops (down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains voltage spikes, which is especially important on Field Day, during DXpeditions, and at portable operating events where emergency power is relied upon.
VFD comment display
All amplifier status indications are explained via detailed
text displayed on the dot matrix, high brightness vacuum
fluorescent display (VFD). The upper line on the VFD always reads peak forward power. LED indicators are provided for: OPERATE mode, attenuation-on, transmit, selected antenna output , and ON/OFF conditions.
Three antenna outputs
Three antenna outputs are selectable using a push-button
on the front panel.
Data regarding amplifier internal status is stored in a
nonvolatile memory for 7 of the most recent auto protection trips. This information can be forwarded to your dealer for diagnostics.
Virtually silent QSK
The input bypassing and vacuum antenna relays are
virtually silent even in the CW QSK mode thanks to
specially designed mounting hardware.
Broadband input matching
Resulting in very good load to the transceiver over the
entire spectrum 1.8-54MHz.
Single 4CX1000A tube
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.
