Input SSB Signal 	20% of full 1.5 KHz Modulation
on / off Ratio 1:4, Interruptions: 30 Hz
There is absolute no time limit for a carrier output power of 12 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.
