This 500-watt amplifier is designed for export, industrial, and scientific applications, offering stable performance with selectable power levels and a built-in preamp.\u003c\/p\u003e\n\u003cp\u003eThe LD500-MOS is compatible with AM, FM, SSB, and CW modes, and operates on a 12–14.5V DC power supply with a 50A current draw. The unit requires a dead key input of 2–4 watts and allows a maximum PEP swing input of 15 watts. A well-tuned antenna with an SWR of 1.5 or less is mandatory for safe and effective operation.\u003c\/p\u003e\n\u003cp\u003eSpecifications  \u003cbr\u003e- **Frequency Range:** 10 meter  \u003cbr\u003e- **Power Supply:** 12–14.5 VDC (Do not exceed 14.2V)  \u003cbr\u003e- **Current Draw:** 50 Amps  \u003cbr\u003e- **Input Power:**  \u003cbr\u003e  - Dead Key: 2–4 watts  \u003cbr\u003e  - Max PEP Swing: 15 watts  \u003cbr\u003e  - Max SSB Input: 20 watts  \u003cbr\u003e- **Output Power:** Rated for 500 watts  \u003cbr\u003e- **Operating Modes:** AM, FM, SSB, CW  \u003cbr\u003e- **SWR Requirement:** 1.1 to 1.5 or less  \u003cbr\u003e- **Connections:** Red = Hot, Black = Ground  \u003cbr\u003e- **Warranty:** 2-Year Manufacturer Warranty (Transistors not included)  \u003c\/p\u003e\n\u003cp\u003eKey Features  \u003cbr\u003e- • 500W low drive transmitter for serious RF applications  \u003cbr\u003e- • Includes built-in preamp and 3 selectable power settings  \u003cbr\u003e- • Supports multiple modes including SSB, CW, AM, and FM  \u003cbr\u003e- • Durable, precision-built  \u003cbr\u003e- • \u003cstrong\u003eFinal-sale only with manufacturer-direct warranty support \u003c\/strong\u003e \u003c\/p\u003e\n\u003cp\u003e**Important Use Restrictions:**  \u003cbr\u003e- For industrial, scientific, medical, or export use only  \u003cbr\u003e- Not legal for use on CB or Amateur bands in the U.S.  \u003cbr\u003e- All sales are **final** – no returns or exchanges  \u003cbr\u003e- Use a proper SWR meter and tune the antenna before operation  \u003cbr\u003e- DO NOT exceed 14.2V supply voltage  \u003cbr\u003e- Always modulate the transmitter to full power before adjusting SWR  \u003c\/p\u003e\n\u003cp\u003eThe LD500-MOS delivers the performance, build quality, and control flexibility required by professionals needing clean, stable high-output RF transmission.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong data-start=\"90\" data-end=\"104\"\u003eDisclaimer\u003c\/strong\u003e\u003cbr data-start=\"104\" data-end=\"107\"\u003eThis linear amplifier is sold for use on the \u003cstrong data-start=\"152\" data-end=\"188\"\u003e10-meter amateur radio band only\u003c\/strong\u003e.
