- 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 (typically 5-10 seconds). The auto-operate function (if enabled) keeps the amplifier in operate mode for you, avoiding unnecessary manual operations.
- No Antenna Tuners
No heavy outboard antenna tuners are needed for antenna VSWRs up to about 3:1. The amplifier will allow you to change antennas virtually instantaneously and enable you to use antennas over wider frequency ranges.
- User Friendly
An amplifier that is both easy to operate and takes care of itself. It is designed to safely withstand up to 400 W of reflected power, up to 100 milliseconds duration of hard drive spikes, "tail" RF after a PTT release, or unintended tuning errors by the operator, etc. The amplifier will also not stop operating with a "soft" AC power cable and will deliver more than half power at only 85% of the nominal mains voltage. It can withstand voltage drops (down to zero volts) for up to 10 milliseconds and can tolerate 15% mains overvoltages, which is particularly important on Field Day, during DXpeditions, and at portable operating events where emergency power is invoked.
- OLED Display
All amplifier status indications are explained via detailed text displayed on the dot-matrix, high brightness and contrast OLED display. The top line on the OLED always reads peak forward power. LED indicators are provided for: mode, attenuation-on, transmit, selected operate antenna output, and condition/OFF.
- Three Antenna Outputs
Three antenna outputs are selectable with a front panel button.
- Easy Maintenance
Data regarding the internal status of the amplifier is stored in non-volatile memory for the 7 most recent automatic protection trips. This information can be sent to your dealer for diagnostics.
- Virtually Silent QSK
The input bypassing and no-load antenna relays are virtually silent, even in QSK CW mode, thanks to the specially designed mounting hardware. Broadband input matching. Load to the transceiver over the entire 1.8-54 MHz spectrum.
- SINGLE 4CX1000A TUBE
Uses a radial ceramic and metal beam tetrode with a 1000 W plate dissipation, specifically designed for Class AB1 RF linear amplifier operation.
- Tube Protection
Permanent monitoring and protection of plate and grid voltages and currents, reflected power, and exhaust air temperature.
