Yaesu's FTX-1 series answers the portable operator who wants flagship receiver architecture in a field-capable chassis. The FTX-1F Field model — the battery-powered configuration — targets the same audience as the Icom IC-705: SOTA and POTA activators, emergency go-bags, and apartment operators who need all-mode HF through 70 centimeters without dedicating a full desktop footprint.
Launched in 2025, the FTX-1F inherits SDR design cues from Yaesu's FTDX101 lineage — direct sampling below 48 MHz, IF sampling above, simultaneous dual-band receive, and a 4.3-inch color touchscreen with 3DSS band scope. It is the most capable portable Yaesu has shipped for multi-band field HF in decades.
Overview
The FTX-1 platform splits into two retail configurations sharing the same "Field Head" transceiver core:
- FTX-1F Field — includes SBR-52LI 6400 mAh Li-ion battery pack for standalone 6W operation
- FTX-1 Optima — adds SPA-1 detachable 100W RF amplifier module for base-station duty
This page focuses on the FTX-1F Field configuration most relevant to portable operators comparing against the IC-705.
Key differentiators from the IC-705:
- Dual simultaneous receivers — monitor two bands or modes concurrently with dual speakers
- C4FM System Fusion — native digital voice on VHF/UHF alongside analog modes
- Larger battery pack — SBR-52LI rated for roughly 9 hours HF SSB at 6W (6-6-48 duty cycle)
- Modular expansion — optional FCX-1 auto-tuner, cooling fan, GPS, Bluetooth without replacing the radio
The IC-705 retains advantages in D-STAR ecosystem, integrated GPS, Wi-Fi remote operation, and a lighter 1.1 kg body. The FTX-1F trades weight (approximately 1.25 kg with battery) for Yaesu filtering philosophy and dual-receive ergonomics. Read best portable radio for SOTA/POTA for side-by-side field use context.
Specifications

| Modes | SSB, CW, AM, FM, C4FM digital, F1D/F2D data |
| Output power | 0.5–6W (SBR-52LI battery), 0.5–10W (13.8V DC ±15%) |
| Receiver architecture | SDR — direct sampling below 48 MHz, IF sampling above |
| DSP | 32-bit IF DSP filtering, noise reduction, notch |
| Display | 4.3" color TFT touchscreen with 3DSS band scope |
| Dual receive | Simultaneous dual-band reception |
| Antenna tuner | Optional FCX-1 external auto-tuner |
| Battery | SBR-52LI 6400 mAh Li-ion (USB-C PD charge, 45W+ recommended) |
| Connectivity | USB ports (rig control, audio, firmware), optional Bluetooth |
| Antenna connector | 50Ω BNC |
| Dimensions | 213 × 89 × 55 mm (Field Head only) |
| Weight | 1.25 kg (2.75 lb) with SBR-52LI |
| Country of origin | Japan |
With optional SPA-1 amplifier attached, the platform delivers 100W base-station output — a upgrade path the IC-705 does not offer natively.
Operating Notes
Field activation with the FTX-1F starts with antenna planning identical to other QRP-class portables: resonant wires, linked dipoles, and compact verticals work well at 6–10 watts. Budget for the FCX-1 tuner if you run non-resonant antennas across multiple bands.
Battery logistics favor the SBR-52LI's capacity over smaller packs — long SOTA days benefit from the rated 8–9 hour duty-cycle figures Yaesu publishes, though cold weather and continuous CQing reduce real-world endurance. Carry USB-C PD charging (45W, 15V 2A) for mid-hike top-ups.
Dual-receive simplifies monitoring a 2m FM calling frequency while working HF — a workflow contest operators appreciate and emergency nets use for simultaneous local and regional awareness. C4FM operators gain integrated System Fusion on VHF/UHF without a separate digital radio.
Digital mode operators run FT8 and similar modes via USB audio and rig control interfaces. Firmware updates ship through Yaesu's standard PC tools — verify current revision after purchase.
Who It's For
The FTX-1F suits Yaesu loyalists wanting portable all-mode coverage without leaving the ecosystem, dual-receive field operators, C4FM System Fusion users, and buyers planning a modular path from 6W field to 100W base via SPA-1. It competes directly with the Icom IC-705 for SOTA, POTA, and go-bag deployments.
Less ideal for operators prioritizing minimum weight, D-STAR networking, or integrated Wi-Fi spectrum display on a tablet. Budget-focused HF-only portable work may still favor the Yaesu FT-891 in a vehicle or the IC-705 if VHF/UHF portability is the primary goal.
