FEATURES

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.

User-friendly
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.

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
temperature.

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.
