Refurbished Icom IC-7300: The Revolutionary HF/50MHz SDR Transceiver with Real-Time Spectrum Scope
Experience the Future of Amateur Radio
Step into the future of amateur radio with the Icom IC-7300, a groundbreaking HF/50MHz transceiver that redefines entry-level performance with its innovative RF Direct Sampling System. By directly digitizing RF signals, the IC-7300 achieves a remarkable reduction in inherent receiver noise, delivering exceptional clarity and sensitivity that will surpass your expectations.
Seamless Digital Mode Operation
Experience seamless digital mode operation with optimized FT8 mode presets and a user-friendly Scroll mode. The constantly evolving firmware ensures you're always at the forefront of digital communication.
Class-Leading Real-Time Spectrum Scope
The class-leading real-time spectrum scope offers unparalleled resolution, sweep speed, and dynamic range. Effortlessly identify and tune to desired signals with a simple touch of the responsive display, which magnifies the selected area for precise tuning. The accompanying high-resolution waterfall function provides a visual history of signal activity, revealing weak signals that might be missed on the spectrum scope alone. The convenient Scroll mode keeps your operating frequency centered within the scope view.
Integrated Audio Scope Function
Analyze your transmit and receive audio characteristics with the integrated audio scope function, displaying vital parameters like microphone compressor level, filter width, and CW keying waveforms in real-time.
Revolutionary RF Direct Sampling System
The adoption of the RF Direct Sampling System marks a significant leap in amateur radio technology. By directly converting RF signals to digital data within the FPGA (Field-Programmable Gate Array), the IC-7300 boasts a simplified circuit design and enhanced overall performance.
Enhanced Receiver Performance with "IP+"
The new "IP+" function further elevates receiver performance by improving the 3rd order intercept point (IP3). This optimization minimizes signal distortion when receiving weak signals in the presence of strong adjacent interference.
Superior Signal Quality
Benefit from class-leading RMDR (approximately 100 dB typical) and significantly improved phase noise characteristics (about 20 dB better than the IC-7200 at 2 kHz separation). This results in cleaner transmit and receive signals, enhancing overall communication quality.
Effective Interference Rejection
Equipped with 15 discrete band-pass filters, the IC-7300 ensures that only the desired RF signal passes through, effectively rejecting out-of-range interference. High Q factor coils minimize loss within these filters for optimal performance.
Built-In Automatic Antenna Tuner
The built-in automatic antenna tuner memorizes tuning settings for rapid band changes, and the Enforced Tuning function provides temporary tuning capabilities for a wider range of antennas in emergency situations.
Intuitive and Smooth Operation
Enjoy smooth and intuitive operation with the combination of the multi-dial knob and the large 4.3-inch color TFT touch LCD. Access menus with a simple push of the multi-dial and make adjustments with a touch and turn. The software keypad on the touch screen allows for easy setting of various functions and memory editing.
One-Touch FT8 Mode Presets
Dedicated one-touch FT8 mode presets allow you to jump into FT8 operation with a single selection from the PRESET menu, with storage for up to five custom presets.
Enhanced Sound Quality
Experience superior sound quality from the newly incorporated speaker unit, housed in a dedicated space within the robust aluminum die-cast chassis.
Convenient Data Storage
The SD memory card slot provides convenient storage for received and transmitted audio, voice memories, RTTY/CW memories, RTTY decode logs, captured screen images, and even firmware updates and personal data for easy configuration.
