| Measured with a Bird Power Meter, Model 43, on Bird dummy load. | 5 W 10 W 20 W 25 W |
460 W 900 W 1800 W 2200 W |
||
| Input SSB Signal | 33% of full 1 KHz Modulation on / off Ratio 1:2, Interruptions: 20 Hz |
|||
| Harmonic Output | 50 dB below rated output | |||
| IMD | 35 dB or better | |||
| Tube | Eimac 4CX1000A | |||
| Tuned input network | ||||
| Output network | Lambda/4 system, impedance: 40 Ohm (best possible value!) | |||
| Computer control | All switching functions, no relais switching under power conditions, soft start inrush, 200 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. |
