SPE Expert 2K-FA
Linear Amplifier

Product Specifications

  • The smallest in its class.
    • Built-in Power supply and Automatic Antenna Tuner.
    • Dimension: L 38, H 18.3, P 43 cm (14.96” W, 7.20” H,16.93” D) (connettors included).
    • Weight: approx: 59.5 lbs (27 kg).
  • The most technologically advanced in the world.
    • Two powerfull CPUs are used.
    • Over 35,000 lines of software for performance that cannot be found in any other amplifier.
  • Fully Automatic.
    • Easy connection with all models "ICOM, YAESU, KENWOOD, TEN-TEC, FlexRadio ELECRAFT" for immediate management of the bands, tuner and antennas.
    • Same performance with all makes or homemade rigs.
    • The operator has only to move the “Frequency Tuning Knob” in the transceiver!!!
  • Wide frequency coverage.
    • 1.8 MHz to 50 MHz including WARC bands.
  • Fully solid state.
    • Up to 2 kW PEP SSB, CW out; 50 MHz included. (+/- 0.5dB)
    • MAX / MID (1kW) / LOW (500W) power selected according to the operator SSB/CW power requirement, for digital modes and for linear protection (automatic).
    • No heating time, immediately ready!
    • Virtually limitless life of the amplification devices ((6 MOSFETs MRF151G).
  • Automatic Antenna Tuner built-in.
    • Capable of matching 3:1 SWR on HF, and 2.5:1 SWR on 6 meters.
    • Capable of programmable switching of 6 antennas (SO239 connectors).
    • Up to 3 antennas for the same band.
    • Management of the SteppIR / Ultrabeam antennas (tuneable).
    • Measure also the SWR of the antenna / cable system.
    • Bands, Antennas, Tuning conditions are changed in 10 msec.
    • Bands, Antennas and Tuning conditions are managed also in “STBY“ to support the exciter only.
    • Max. attenuation 0.8 dB.
    • Bypass capability.
    • Remotable (option).
  • SO2R.
  • Two inputs available.
    • SO239 connectors.
  • High power gain (up to 14.5 dB).
    • In “OPERATE“ the required drive power is automatically set with an ALC connection and in “STANDBY“ the exciter is then automatically reset to full power.
  • Very clean and low distortion output!
    • Spurious emissions less than -60 dB ( 50 MHz –65 dB ).
    • 3rd order distortion (two tone test) 36 dB typ.
  • Input 50 ohm always perfectly matched.
    • SWR less than 1.2:1.
  • Fully protected.
    • Temperature, Over-Voltage, Over-Current, SWR, Reflected Power, Max RF Tuner Voltage, Over-Drive, Amp. The correct parameters are continuously monitored.
    • The same protection is realized in two different ways:
    • Via hardware circuits (HW) to assure great speed.
    • Via the software (SW), to assure great accuracy.
    • Thanks to the SW, transmit relay changeover is carried out with zero current at the contacts.
  • Full break-in operation (QSK).
  • Quiet operation.
    • Linear management of the speed of the cooling fans of the heatsink.
    • In the power supply, fans speed is reduced during the reception.
    • Since, considering the big power developed, a significant amount of heat must be removed, every precaution is used to keep the lowest possible the noise of the fans.
  • Continuous use.
    • “MAX” mode: SSB / CW unlimited.
    • Automatically switches to “MID” for a while if, in “MAX”, a continuous signal (RTTY) is transmitted.
    • “MID” “LOW” modes, RTTY unlimited.
  • Switching power supply.
    • Continous input between 190 – 255 Vac, 47-63 Hz.
    • PFC (Power Factor Correction).
  • The linear can be switched ON / OFF also switching ON / OFF the exciter.
  • Fully remotable.
  • Large LCD displays a greater amount of information.
    • W PEP out, V pa, I pa, W, Power gain, Temperatures, SWR (after and before the ATU), Input setting, CAT setting, Band and other indications including an alarms log.
  • Easy to operate.
    • Powerful SW gives you a user-friendly unit.
  • USB port.
    • For remote control.
    • For new SW releases download.
  • Easy transportation.
    • A sturdy carry-bag is supplied for "QSY, FIELD DAY, DX’ PEDITIONS etc."
  • Certifications : CE, FCC.
