Icom IC-7300MK2 HF/50MHz Base Transceivers

Icom IC-7300MK2 HF/50MHz Base Transceivers are an advanced evolution of the original IC-7300, designed for superior performance and equipped with modern connectivity. Connectivity upgrades include a first for Icom HF transceivers: the MK2 integrates an HDMI™ output for external display of spectrum scope, waterfall, and audio. Additionally, USB Type-C™ interfaces with dual virtual COM ports and audio I/O enable simultaneous use of digital modes and logging software, while LAN ports provide simplified RS-BA1 remote control without the need for a base station PC.

The IC-7300MK2 features an improved Reciprocal Mixing Dynamic Range (RMDR) of approximately 105dB at 2kHz separation and transmit phase noise reduced to –139dBc/Hz at 1kHz offset, delivering cleaner signals and enhanced adjacent-signal handling. Power efficiency is optimized with standby current reduced from 0.9A to 0.7A, minimizing heat generation for stable long-duration operation.

Additional enhancements include built-in CW decoding, RX antenna IN/OUT connectors for external filters or preamps. These refinements make the IC-7300MK2 a high-performance, feature-rich solution for serious HF operators seeking cutting-edge SDR technology with robust remote and display capabilities.
