DXPatrol Charon Adalm-Pluto HF Transverters unlock the full potential of your ADALM‑Pluto SDR by expanding its frequency coverage far beyond the stock 325MHz–3800MHz range. The DXPatrol Charon HF Transverter bridges the gap, enabling true HF operation and giving experimenters access to the 160-6-meter amateur bands with an output power of 50mW—greatly expanding the Pluto’s capabilities for research, learning, and on‑air experimentation.

At the heart of the Charon is a stable 80MHz local oscillator, allowing clean and reliable frequency conversion into the HF spectrum. The built‑in VOX system automatically switches the unit into transmit mode, while a two‑color status LED clearly indicates RX or TX state. For operators who prefer manual control, a dedicated PTT jack input is also provided.

Configuration is simple: the necessary parameters for transverter operation can be set directly in the ADALM‑Pluto software, and the displayed operating frequency remains accurate after conversion. Power is supplied through a standard 12–16VDC input, and the unit uses SMA (female) connectors for both antenna and Pluto RX/TX interfacing.

The Charon HF Transverter is housed in a lightweight, 3D‑printed PLA enclosure, providing a compact and practical solution that integrates seamlessly into your SDR setup.
