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.


Easy maintenance

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.


Tube protection

Permanent monitoring and protection of plate and grid

voltages  and  currents,  as  well  as  of  the  exhaust  air
