The Yaesu FTX-1 Optima is built for operators who refuse to compromise—whether they’re contesting from a full station or chasing DX deep in the field. Combining the compact versatility of the FTX-1 Field Head with the muscle of the SPA-1 100W Power Amplifier, this hybrid SDR transceiver transforms seamlessly from a lightweight portable rig into a full-featured 100-watt HF/50/144/430 MHz station with zero tools and zero hassle.

Attach the amplifier to the Field Head and run a full 100W using any 13.8VDC external power supply. Need to go portable? Pop off the amp and slot in the included 10.8V 6400mAh Li-ion battery for 6W QRP, or hook up an external 13.8V supply for 10W field operation. The Optima adapts instantly to your operating style—backpack-ready one moment, station-class the next.

Despite its compact size, the FTX-1 Optima is packed with modern comforts: true dual-band C4FM capability, simultaneous receive, APRS® support (coming August 2025), FT8-friendly PRESET mode, memory channel scope, and a clear VFO Mode indicator that keeps your operating status obvious at a glance. Its SDR architecture delivers excellent clarity, responsiveness, and reliability across modes, while a powerful 4W audio system ensures loud, clean output.

For operators who value flexibility without sacrificing performance, the FTX-1 Optima stands in a class of its own—rugged, modular, and ready for real-world radio.
