BLA-300 (All-band HF Amplifier, SW 1.5 - 30MHz)

This unit can be used with our AM MAX II DSP transmitters to increase output power up to 300W. We do not recommend pushing the unit too much unless extreme measures are taken as far as cooling is concerned. Additional fans are required for permanent operation as this unit was designed primarily for communication (where it cools at least 50% of the time).

It also contains receive preamplifier for 10-30MHz.

Auto or manual microprocessor controlled band switching. 6 Low pass filter inside. Output power indicator. Auto TX/RX switching with SSB delay switch. Rear panel connection for external TX/RX switching. High SWR and over temperature protection, excessive input power protection. Forced multispeed ventilation.

Includes mains power supply: speficy 110V or 220V

Unit ships with instructions and schematic diagram for easy troubleshooting.
