| Heading: | Harris - Model 740 HF Transmitter 10 KW |
| Ad Message: | Harris / RF High Frequency (HF) Model 740M - AUTOTUNE Transmitter / Amplifier Autotune - 2 to 30 Mhz Rated at Continuous Duty - 10,000 Watts RF Output This Transmitter utilizes a 4CX15,000 Tube as it's Final Power Amplifier, which as seen in the pictures is included in the amplifier Pi-L Output Network for Best Transmit Spectrum Quality Servo tuned Vacuum Variables in Final Power Amplifier The Final Amplifier slides out for ease of servicing. The transmitter is self contained and designed for either local or remote controlled operation. Would be ideal for a HF Shortwave Station or Big Gun Ham Station, somewhere in the world. As I recall, the Synthesized Exciter has approximately 100 MW of RF output, which drives The Intermediate Power Amplifier (similar to a Harris RF-110A), which uses two 4CX1500B tubes and should put out 3000 - 4000 watts of RF output by itself. As removed from Commercial Service We have many more internal pictures that we can email you. |
