1500W CW/SSB on 50 MHz

Driving power: 40 to 60 W for maximum output power

Input impedance: VSWR at 50 Ohms <1.5: 1

Output amplification: 17 dB

Output impedance: 50 Ohm unbalanced

Maximum Output SWR: 3:1

SWR protection: Automatically switches to STBY when reflected power is 350W or more

Intermodulation distortion: better than -32 dBc

Harmonic suppression: min -50 dBc (30-54 MHz better than -70dBc)

AUTO tuning response speed: less than 0.5s within the same BAND, less than 3s if out of BAND

TRXs-CAT supported: ICOM, ELECRAFT, KENWOOD, TEN-TEC ORION, YEASU,

Icom transceive protocol using microHAM devices - CI-V OUPUT,

Flex Radios and Anan (Apache Labs)

Tube: FU-728F ceramic tetrode

Cooling: Centrifugal fan + axial fan

Electrical power supply: Switchable 220,230,240 V - 50/60 Hz or other primary voltages

(e.g. 200V 50/60Hz for Japan)

Transformers: 1 toroidal transformer 3.0 kVA

Protection circuitry: - VSWR too high

  - Anode current too high

  - Anode voltage error

  - Screen current too high

  - Screen voltage error

  - Mains current too high

  - Mains voltage error

  - Heating voltage error

  - Power amplifier mistuning

  - Temperature too high

  - Soft start for fuse protection

  - "switch-locked" at amplifier open

Indications: 4.3" color touch screen display

Features: - Automatic external antenna switching

  - Automatic switching between bands

  - Automatic tuning within the band based on segments

  - Automatic switching of the band pass filter

  - Memory for faults and warnings, easy maintenance

  - Automatic anode current configuration (BIAS): no need to manually adjust after changing the tube

  - Three programmable working modes of centrifugal fan (turbine) + axial fan

  - T / R system: QSK operation with built-in vacuum RF antenna relay

  - Easy transport thanks to the detachable HV transformer

  - Remote control - connector for LAN connection

  - The power amplifier is sensitive to high frequencies (automatic frequency reading even in the absence of CAT)

  - The smallest and lightest 2000W automatic PA on the market

The power amplifier is interfaced to the LAN via Lantronix's XPORT (type XP1001000-05R).   More information can be found at   www.lantronix.com   .

The XPORT factory default settings are:

IP address:   192.168.1.211

These are strictly default settings.   You can change any of these by accessing the XPORT Web GUI via your web browser.   It is not recommended to change any other parameters of the XPORT interface as this may cause loss of communication.   There is no default username or password.   It is strongly recommended to protect the web interface with a username and password.

For remote control and monitoring via LAN, special software is required. It is available free of charge; can be downloaded from the following address:

NOTE: For the software to function properly, you must have accessible LAN ports 9999 and 10001.
