SPE Expert 1K-FA
Linear Amplifier

Product Specifications

  • The smallest in the world!
    • Built-in Power supply and Automatic Antenna Tuner.
    • Dimension: 11.02” W, 5.51” H, 12.60” D (w 28, h 14, d 32 cm.) (connectors included).
    • Weight: approx. 44 lbs (41.8 lbs typ.) 20 Kg (19 Kg typ.).
  • The most technologically advanced in the world!
    • Two CPUs are used, one of which is dedicated to the transceiver interface requirements (CAT).
    • Pi-L output circuit.
    • Over 13,000 lines of Software for operational and protection circuits
  • 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.
  • Full solid state!
    • 1 KW pep SSB output; 900 W pep CW out (typ.) ; 700 W pep out. (typ.) on 50 MHz.
    • FULL / HALF 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 (MOSFETs).
  • 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 4 antennas (SO239 connectors).
    • Up to two antennas for the same band.
    • Bands, Antennas, Tuning conditions are changed in 10 msec.
    • Bands, Antennas and Tuning conditions are managed also in “STBY“ to support the exciter only.
  • SO2R.
  • Two inputs available.
    • SO239 connectors.
  • High power gain (up to 15 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 -50 dB ( 50 MHz –60 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)!
  • Normal / Contest operation to optimize the performances!
  • Very quiet operation!
    • Seven quiet three-speed cooling fans:
      • 150 CFM maximum total air flow.
    • Temperature thresholds for speed change:
      • 104 °F (40 °C), 158 °F (70 °C)and 181 °F (83 °C). (normal mode).
      • 140 *F (60 °C). and 167 °F (75 °C). (contest mode).
    • Noise level:
      • 39 dBa at maximum blower speed.
  • Continuous use
    • "FULL" mode: SSB unlimited, key down 2 minutes.
    • "HALF" mode: SSB unlimited, key down 5 minutes.
  • Regulated power supply, input 230 / 215 / 200 / 115 / 100 Vac
    • With all input voltages the output power doesn't change.
    • A well designed grain-oriented, tape-wound toroidal transformer reduces magnetic fields around the amplifier.
  • The linear can be switched ON / OFF also switching ON / OFF the exciter
  • Large LCD displays a greater amount of information.
    • W pep out, V pa, I pa, W pep reflected, Power gain, Temperature, SWR, Input setting, CAT setting, Band and other indications including an alarms log.
  • Easy to operate
    • Powerful SW gives you a user-friendly unit.
  • RS 232 port for PC control
    • SW is supplied to remote the linear front panel.
    • With a proper protocol it is possible to use this port not only as a remote control but also as a CAT port (useful to link the linear with any customer application).
  • Easy transportation!
    • A sturdy carry-bag is supplied for "QSY, FIELD DAY, DX’ PEDITIONS etc."
  • Certifications: CE, FCC.
