HL-300 (HF Amplifier, HF 1.5 - 30MHz)

This unit can be used with our AM MAX II DSP transmitters to increase output power up to 300W (550W peak). 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).

Auto or manual microprocessor controlled band switching. 6 Low pass filter inside. LED band indicator. Bargraph LED output indicator. Auto TX/RX switching with SSB delay switch. Rear panel connection for external TX/RX switching. High SWR and over temperature protection.

Requires a suitable mains power supply: 13.8V/40A

Unit ships with instructions and schematic diagram for easy troubleshooting.
