U20532 Used RF-Power RF2K-S HF/50MHz Solid State Amplifier 1500W

U20532 Used RF-Power RF2K-S HF/50MHz Solid State Amplifier 1500W

This pre-owned RF-KIT RF2K-S solid-state linear amplifier is in great overall condition, showing only light handling nicks along the black powder-coated enclosure and a minor superficial scratch on the front touchscreen lens that does not affect readout visibility or touch operation. The chassis is structurally solid, the front ventilation grilles are clean, and the large color display bezel is firmly seated. On the rear, the high-power cooling exhaust fan, four SO-239 antenna ports, transceiver input jack, grounding post, and low-voltage control interfaces (CAT, LAN, Multi-Interface, PTT) are clean and undamaged. It comes complete with a heavy-duty NEMA 6-15P to IEC C19 AC power cord.

The RF-KIT RF2K-S is an elite, fully legal-limit solid-state amateur radio power amplifier engineered for whisper-quiet, high-efficiency operation across 160 meters through 6 meters (1.8–54 MHz). Powered by dual high-durability LDMOS transistors, it effortlessly delivers a full 1500 Watts PEP of output power across all modes (SSB, CW, RTTY, and digital FT8) with low drive power requirements (typically 50W or less). Built around a Raspberry Pi internal controller, it features an intuitive 7-inch color capacitive touchscreen interface displaying real-time forward power, reflected power, SWR, and temperature metrics. With a built-in wide-range automatic antenna tuner (ATU), 1 transceiver input and 4 switchable antenna ports, internal directional coupler with predistortion output (-55 dB) for PureSignal adaptive linearization, silent variable-speed fan cooling, and full Ethernet/LAN network remote control, the RF2K-S is one of the most advanced solid-state linear amplifiers on the market.

Condition

• Cosmetic Condition: Great pre-owned condition overall. Displays small handling nicks and minor cosmetic surface marks along the edges of the metal cabinet.

• Touchscreen Lens: Features a small cosmetic surface scratch on the screen lens; display visibility, backlight illumination, and touch responsiveness remain fully unimpeded.

• Connectors & Rear Hardware: All five SO-239 RF ports (1 TRX in, 4 Antenna out) have clean threads. The power inlet, CAT, LAN, Multi-interface, and PTT sockets are solid and clean.
  

Key Features

• Full Legal-Limit Output: Delivers up to 1500 Watts PEP on 160M through 6M across SSB, CW, and digital modes.

• Dual LDMOS Architecture: Utilizes robust modern LDMOS final transistors engineered for high efficiency, linearity, and thermal durability.

• 7-Inch Color Touchscreen Display: Bright, high-resolution capacitive touch panel providing real-time digital/peak metering, band switching, and status telemetry.

• Integrated Automatic Antenna Tuner (ATU): High-speed internal tuner quickly matches complex antenna loads across all amateur bands.

• 4-Port Antenna Matrix: Four individually selectable SO-239 antenna outputs configurable per band.

• Predistortion / PureSignal Ready: Dedicated rear SMA output (-55 dB) feeds clean RF samples back to modern SDR transceivers for exceptional signal purity.

• Extensive CAT & Network Control: Rear LAN port, CAT interface, and Multi-Interface port allow seamless transceiver tracking and web-based remote control.

• Ultra-Quiet Active Cooling: Variable-speed cooling fans maintain low internal temperatures during long contest or digital duty cycles.
