Icom HF 7300 (Pre-Owned) MARS
Icom IC-7300 HF/50 MHz Transceiver — Pre-Owned
The Icom IC-7300 is a high-performance HF/50 MHz transceiver that brings cutting-edge SDR (Software Defined Radio) technology to amateur radio operators in a compact, user-friendly design. Built around Icom's innovative RF Direct Sampling system, the IC-7300 delivers exceptional receiver performance, superior dynamic range, and remarkably clear signal processing.
Advanced RF Direct Sampling
Unlike traditional superheterodyne radios, the IC-7300 samples RF signals directly, reducing distortion and enhancing signal clarity. The result is cleaner reception, improved phase noise characteristics, and better handling of strong adjacent signals.
Real-Time Spectrum Scope
The large 4.3-inch color touchscreen display features a high-resolution real-time spectrum scope and waterfall display. Operators can visually monitor band activity, identify open frequencies instantly, and tune signals with simple touch control.
Powerful Receiver Performance
- 15 discrete band-pass filters
- Excellent RMDR (Reciprocal Mixing Dynamic Range)
- Digital IF filtering with adjustable bandwidth
- Built-in noise reduction and noise blanker
The IC-7300 excels in crowded band conditions, making it ideal for contesting, DXing, and everyday operation.
Built-In Sound Card & USB Connectivity
With an integrated USB sound card and CAT control, the IC-7300 connects easily to a computer for digital modes such as FT8, RTTY, PSK31, and more — no additional interface required.
