Features of the Toptek PA-350V Amplifier:

• Wideband Solid State VHF power amplifier delivers over 350 watts of RF output typically with only about 8 or 15 watts of drive power

• Selectable input power ranges

• Alphanumeric LCD display for various measurements, user configuration and error conditions

• Output power (FM) selectable between three user programmable levels

• Selectable FM or SSB/CW modes with key-up delay and PEP metering

• Multiple protection features: high drive, high SWR, high/low DC voltage, high temperature

• Automatic Level Control (ALC) for output power regulation and high SWR protection

• Individual DC current sensing and limiting of each sub-amplifier

• Receiver Low Noise Amplifier (LNA) with a bandpass filter to prevent blocking by HF signals

• Two elegant, thermostatically controlled fans

• RF sense or PTT keying (menu selected)
