Input SSB Signal 20% of full 1.5 KHz Modulation
on / off Ratio 1:4, Interruptions: 30 Hz
Output limited by Software RTTY / CW / SSB:   13 KW / 25 KW / 45 KW
Harmonic Output 50 dB below rated output
IMD 34 dB or better
Tube Eimac 4CX15000A
Input network 1:9 Transformation, 450 Ohm, 500 W HF Resistor, Tube Input Reactance Compensation & Neutralization for each Band, 11 pol. bandswitch, two levels
Output network Roller inductor 22 uH, Vacuum Caps: 500 pF var. / 15 KV + 2500 pF var. / 5KV
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.
