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.
