||
| 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: 20 KW / 40 KW / 105 KW | |||
| Harmonic Output | 50 dB below rated output | |||
| IMD | 33 dB or better | |||
| Tubes | Two Eimac 4CX15000A | |||
| Input network | 1:9 Transformation, 450 Ohm, 500 W HF Resistor, Tube Input Reactance Compensation & Neutralization for each Band | |||
| Output network | Fixed inductors 2+18 uH, Switch: Multi-Tech Model 92, Vacuum Caps: 500 pF var. / 15 KV + 2500 pF var. / 5 KV | |||
| 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 blowerWell 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. |
