Yaesu FTX-1 Series HF/50/144/430MHz SDR All Mode Base/Portable Transceivers

Yaesu FTX-1 Series HF/50/144/430MHz SDR All Mode Base/Portable Transceivers provide continuous wide-range RX coverage from 30kHz through 174MHz, and from 400 through 470MHz including SWL, FM broadcast, and Air-band. TX band coverage includes HF 160 – 10M, with the addition of 6M, 2M, and 70cm.

The Yaesu FTX-1 Field is perfect for portable field operation. This model features up to 10W of power output when used with an external 13.8VDC power supply. By attaching the SBR-52LI Li-ion to the rear of the Field Head, the FTX-1 provides 6W (5W for QRP) stand-alone operation on HF through V/UHF bands in all modes – SSB, CW, AM, FM and C4FM digital. 9-hour stand-alone operating time with 6W on HF bands (SSB), and 8-hour operating time with 6W on V/UHF bands (FM) are available (6-6-48 duty cycle). The FTX-1 Field Head can charge the included Li-ion battery automatically when connected to an External 13.8VDC power supply or use an optional third-party USB Type-C PD (Power Delivery) cable to recharge the battery (45W or greater/ 15V 2A).

FTX-1 Field Included Items:

• FTX-1 Field Head

• SBR-52LI – 10.8V 6400mAh Li-ion Battery

• DC Power Cable with a 6.3mm OD 3.1mm ID 9.5mm long 2-pin Round Power Plug

• SSM-75E Hand Microphone

The Yaesu FTX-1 Optima

The FTX-1 Optima includes the SPA-1 100W Power Amplifier and, like the FTX-1 Field, supports operation across the HF to V/UHF bands in all modes: SSB, CW, AM, FM, and C4FM digital. The FTX-1 Field and FTX-1 Optima both use the same “Field Head” unit. By connecting the power amplifier to the back of the Field Head—without any tools—you can instantly upgrade the FTX-1 into a powerful 100W base or portable transceiver when using an external 13.8VDC power supply.

The Optima is capable of low-power operation at 6W (5W QRP). The SPA-1 power amplifier can be quickly detached and replaced with the included 10.8V 6400mAh Li-ion battery. Alternatively, 10W field operation is supported using an external 13.8VDC power supply—both configurations allow rapid, tool-free reconfiguration

Yaesu FTX-1 Optima Included Items:

• SPA-1 100W RF Power Amplifier

• Heavy-Duty DC Power Cable for SPA-1 (25A)

• SBR-52LI – 10.8V 6400mAh Li-ion Battery

• DC Power Cable with a 6.3mm OD 3.1mm ID 9.5mm long 2-pin Round Power Plug for Field Head

• SSM-75E Hand Microphone

Yaesu FTX-1 Series Key Features

MAG (Memory Auto Grouping) – (HF/VHF/UHF)- Memory channels are automatically grouped and an be recalled by Band Groups – HF, VHF, UHF, and others.

QMB (Quick memory Bank) – (HF/VHF/UHF) – Frequency, mode, and all settings and parameters of the current receiving signal can be quickly stored and recalled.

PMG (Primary Memory Group) – (VHF/UHF) – PMG channels can always be scanned and heard – which is useful when watching the channels club members use to communicate.

AMS (Automatic Mode Select) – (VHF/UHF) – AMS automatically determines whether the receiving signal is C4FM Digital or FM and sets the receiver to the appropriate mode.

3DSS (3-Dimensional Spectrum Stream) - The 3DSS Real-time Spectrum Scope presents the constantly changing band conditions in three dimensions (3-D).

High-Resolution 4.3-inch TFT Color Touch Panel Display - The large 4.3-inch wide full-color touch panel display affords outstanding visibility and intuitive management of the operating frequency, meters and main function settings.

3 Display Modes – Dual-Band Display (Right/Left), Dual-Band Display (Up/Down), Single-Band Display, switchable according to the user’s preference and usage.

Yaesu RF-Front End with Superb Interference Rejection - While the FTX-1 is compact, it boasts excellent proximity two-signal characteristics thanks to a powerful RF Front-End design with 10-divided BPF (Band Pass Filter) in amateur bands from HF through UHF and RF amplifier with a low NF (Noise Figure) which is excellent in intermodulation characteristics. In addition, a high-purity 110.592MHz oscillator circuit configuration supplies a high-quality sampling clock signal with excellent C/N characteristics to the ND converter.
