Description
RADIO HSM1G – 50W 40m Mono Band SDR Transceiver
Built to Connect. Built to Last.
Overview
After months of design, prototyping, and extensive on-bench testing, Hambuilder Radiowork introduces the HSM1G — a compact 50W HF transceiver purpose-built for the 40-meter band. It is designed for operators who prioritize simplicity, reliability, and real-world on-air performance over unnecessary complexity.
Design Philosophy
HSM1G is built around a single principle:
Less Complexity. More Operating.
We believe a great transceiver should not require deep menu navigation to perform. The HSM1G features a compact, rugged aluminum enclosure, an intuitive front-panel layout, a large precision tuning dial, and a clear full-color display. Every control is positioned where it should be — allowing the operator to focus on the QSO.
Key Features
50W RF Output Power – Solid, dependable power for daily operation, DX chasing, and contest use
Mono Band Optimized – 40 Meter Band – RF chain optimized specifically for 7.0 – 7.3 MHz for maximum efficiency and stability
Full-Color Display with Spectrum & Waterfall – Real-time visual monitoring of band activity, as demonstrated from 7.040 MHz to 7.055 MHz with smooth, precise tuning
Ergonomic Front Panel Architecture – Dedicated POWER switch, heavy-duty MIC connector, six direct-access function keys, large DIAL encoder, and independent AF-GAIN control
Compact & Portable Form Factor – Ideal for base station, portable operations, and field deployment
Rugged Aluminum Construction – Superior thermal management and long-term durability
Intuitive Operation – No complex layering. Power on, tune, and operate.
Built for Real Operation
Whether calling CQ, chasing DX, participating in contests, or enjoying casual evening QSOs, the HSM1G delivers stable, confidence-inspiring performance where it matters most — on the air.
More than just another transceiver, the HSM1G is engineered by amateur radio operators who understand what matters: stable receiver performance, clean transmit audio, straightforward operation, and equipment you can trust every time you press the PTT.
