|||
| Output limited by Software | RTTY / CW / SSB: 2800 W / 4000 W / 8000 W | |||
| Harmonic Output | 50 dB below rated output | |||
| IMD | - 48 dB @ 6000 W SSB output (working with Class A) | |||
| Tube | Svetlana GU-95b | |||
| Input network | 50 Ohm, 200 W HF Resistor, 5 pol. Chebychev Low Pass Filter, switched |
|||
| Output network | Inductor: 19 uH, Caps: 250 pF var. + 390 pF fixed / 1000 pF var. + 330 nF fixed | |||
| Computer control | Plate current (every 5 msec), SWR, all switching functions, no relais switching under power conditions, soft start inrush, 300 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. |
