• 1000W PEP SSB, 800W CW on 50 MHz,
• 800W on RTTY
• Input power: 35 to 40 W for full output power
• Input impedance: 50 Ohm VSWR < 1.5 : 1
• Output amplification: 14 dB
• Output impedance: 50 Ohm unbalanced
• Maximum output SWR: 2:1
• SWR protection: Automatic switching to STBY when reflected power is 250W or higher
• Intermodulation distortion: 32 dBc
• Suppression of harmonics: min -50 dBc (between 30–54 MHz better than 70dBc)
• Tube: GS-23B ceramic tetrode
• Cooling: Centrifugal blower
• Power supply: Switchable 220, 230, 240 V – 50Hz
• Transformers: 1 toroidal transformer 1.6 kVA

  Protection circuits: – SWR too high
  – Anode current too high
