In spring 2025, Yaesu introduced its latest SDR transceivers, the FTX-1F and FTX-1 Optima, which represent a new generation of modern, versatile, and modular handheld and base station-class radios. With these models, the company targets portable (SOTA, POTA), QRP, and high-performance home operators alike. The development focused on innovations such as dual receivers, a full touch-screen interface, and modular final amplifier options that bring portable SDR flexibility to a whole new level.
Compared to previous models like the FT-818 or FT-891, this series represents a significant leap forward with SDR architecture, integrated digital signal processing, and a colorful touch display that enhances the user experience. Yaesu’s goal was to combine classic Yaesu reliability with the technological expectations of the 2020s in a single platform.
Yaesu FTX-1F – Compact SDR Transceiver for the Field
Key Features:
Beyond the factory specifications, real-world field tests confirm that the FTX-1F delivers 9–10 hours of runtime with a 50% transmit/receive duty cycle. Tests included typical SSB and FM operation as well as digital modes like FT8 using various antenna configurations. The device remains stable in temperature fluctuations, and the automatic display brightness adjustment helps conserve battery life.
- Frequency coverage: HF, 50 MHz, 144 MHz, 430 MHz
- Modes: SSB, CW, AM, FM, C4FM
- Output power: 6 W (battery), 10 W (external power)
- Display: 4.3” color touch display
- Dual independent receivers
- 32-bit IF DSP
- Battery: 6400 mAh, ≥9 hours runtime
- Weight: approx. 1.25 kg
The FTX-1F is ideal for mobile use, hiking, backpacking, and POTA/SOTA activations, where light weight and long internal battery life are essential. Field testing shows 9–10 hours of operation with intermittent TX, which is outstanding in this class. The dual receiver allows simultaneous band monitoring and operation.
Pros and Cons

Yaesu FTX-1 Optima – Expanded SDR Base Station
The Yaesu FTX-1 Optima is based on the same architecture as the FTX-1F but extended with the SPA-1 amplifier module, making it suitable for high-power base station operation.
Highlighted Features:
When using the SPA-1 amplifier, a separate stable 13.8 V / 20 A power supply is needed to achieve full output, especially for continuous or digital modes like FT8. The built-in active cooling system runs at a quiet 28–32 dB, unobtrusive even indoors. Temperature-controlled fans engage only under higher load and adjust RPM automatically for protection.
- Output power: 100 W on HF/50 MHz, 50 W on VHF/UHF
- SPA-1 with active cooling, quiet operation
- Built-in speaker (2.5 W) with excellent voice clarity
- Dual antenna inputs (HF and V/UHF) – quick switching
- WiRES-X compatible for digital networking
- PMG and MAG memory functions displayed on-screen
This amplifier module is ideal for home or mobile station use, enabling the full potential of the SDR platform.
Pros and Cons
Pros:
- True 100 W HF output
- Expandable with amplifier module
- Separate antenna ports for HF and VHF/UHF
- High dynamic range SDR receiver
Cons:
- SPA-1 shipped as a separate unit, requires extra space
- Higher power consumption
- Portability somewhat reduced
Accessories and Expansion Modules
Both models are compatible with the following accessories:
- FC-90: automatic antenna tuner (up to 150 W)
- SCF-1: cooling fan module for FT8 or heavy duty operation
- BU-6: Bluetooth module for Android/iOS remote control
- FGPS-5: GPS module for APRS and location-based features
These add-ons significantly increase system flexibility, enabling digital and network features such as APRS, Bluetooth remote control, and VOX with wireless headsets.
Real-World Use Scenarios
SOTA and POTA Activation (FTX-1F)
Thanks to its low weight and energy efficiency, the FTX-1F is a top choice for field use, where quick setup and stable runtime are essential. Its dual receiver enables continuous monitoring of active bands while operating. The device pairs quickly with various antennas (e.g., EFHW, vertical), and is ready for use after tuning.
Home Station Operation (FTX-1 Optima)
The SPA-1 amplifier provides 100 W output and dual antenna ports for multi-band operation. PMG and MAG features allow fast band changes in contests or expeditions. The display supports simultaneous monitoring of multiple channels visually.
FTX-1F vs Icom IC-705 – Portable SDR Transceivers Compared

| SDR architecture | Direct conversion | Direct conversion |
| Price (estimated) | Lower mid-range | Higher price tier |
Assessment
- FTX-1F: shines with modular expandability, long runtime, dual receiver, and outdoor focus.
- IC-705: offers integrated features but with shorter runtime and a higher price point. Built-in Bluetooth and GPS are advantages.
Digital Modes Support and SDR Flexibility
Both the FTX-1F and Optima fully support modern digital modes like FT8, JS8Call, PSK31, and WSPR. The built-in 32-bit DSP and IF-based noise reduction provide clean reception even on noisy bands. The radios easily integrate with software such as WSJT-X and FLDigi through a digital interface. The SCF-1 cooling module is strongly recommended for continuous FT8 use.
Example Configuration for Digital Modes:
- Software: WSJT-X, GridTracker, FLDigi
- Interface: SignaLink USB or simple USB-C sound card
- Cabling: USB-C data cable to PC/laptop, or separate RX/TX audio lines
- Settings: CAT control using Yaesu protocol, VOX or PTT relay
This configuration ensures stable connection and minimizes distortion in FT8 or JS8Call, even in portable setups using a laptop or tablet.
Expected Software and Firmware Updates
Yaesu traditionally emphasizes firmware upgradability. The FTX-1 series will receive regular firmware updates with new features, bug fixes, and enhancements. Updates are available via USB and the official Yaesu website. WiRES-X integration and support for future digital modes are also expected. The company has announced plans to release an Android app for remote operation.
Community Reception and Availability
The amateur radio community has responded positively to the new Yaesu models, especially praising the FTX-1F’s field performance and the Optima’s high output capabilities.
