Input SSB Signal 10% of full 1.5 KHz Modulation
on / off Ratio 1:9, Interruptions: 30 Hz
Output limited by Software RTTY / CW / SSB:   25 KW / 40 KW / 100 KW
Harmonic Output 50 dB below rated output
IMD -32 dB or better (with predistortion mode: better -50 dB)
Tube Eimac 4CX20000C
Input network 1:9 Transformation, 450 Ohm, 500 W HF Resistor, Tube Input Reactance Compensation & Neutralization for each Band
Output network Monster large roller inductors 15 uH, 60 A, Caps: Plate: 450 pF var. / 25 KV + 330 pF fixed and Antenna: 2000 pF / 8 KV + 1 NF fixed
Computer control Plate current (every 5 msec), SWR, all switching functions,
no relais switching under power conditions, soft start inrush, 10 sec delay time for full power, 2 speed turbine blower

Well regulated screen and grid supply for +ve and -ve currents as well as current limiting to protect the tube and minimize the IMD. It is impossible to override the screen and grid dissipation at any working conditions.
Auto Tune With a CI-V (ICOM) interface (or similiar) to transceiver: Complete auto tune on all HF bands. Normal time for automatic change of frequency: 1 second; change of band: 2–8 seconds
