ICOM IC-7300MK2 HF/50/70MHz TRANSCEIVER

Preliminary characteristics.

The IC-7300MK2 is a compact all-mode transceiver for HF/50 MHz; in the European version, 5 MHz and 70 MHz are also included. It brings noticeable updates in receiver/transmitter performance, connectivity, and efficiency.

What’s new in the MK2 — at a glance

Improved RMDR (≈ 105 dB at 2 kHz) and significantly lower TX phase noise (typ. −139 dBc/Hz)

HDMI™ output for an external monitor with spectrum/waterfall (optional audio)

Integrated CW decoder — Morse decoding without a PC

RX-Antenna IN/OUT (SMA) for separate receive paths, filters, or preamps

USB-C with two virtual COM ports plus audio (e.g., FT8 and logging in parallel)

LAN remote with RS-BA1 (V2, optional, sold separately) — incl. remote power ON/OFF, no server PC required

Reduced RX standby current (about 0.7 A) for lower heat

Unchanged operating logic

The user interface is identical to the IC-7300. Menus, touch operation, and workflows are in the same places, minimizing retraining and errors in club or multi-user shacks.

Receiver and transmitter design

Stronger large-signal handling via higher RMDR; TX phase noise is reduced (typ. −139 dBc/Hz at 1 kHz offset). In practice: less adjacent-channel impact on receive and “cleaner” transmitted signals. RMDR (Reciprocal Mixing Dynamic Range) describes immunity to reciprocal mixing caused by oscillator phase noise in the presence of strong adjacent signals.

Efficiency & thermals

RX standby current decreases from 0.9 A to 0.7 A (typ.). Lower dissipation means less heating and stable long sessions, e.g., in contests.

Display & decoder

The HDMI™ output can show frequency, spectrum/waterfall, menus, and optionally audio on a large external monitor. The integrated CW decoder reads Morse without a PC; filtering and speed are adjustable.

Flexible receive paths & connectivity

Separate RX-Antenna IN/OUT (SMA) allow dedicated RX antennas, band-pass filters, or preamps. Via USB-C, two virtual COM ports plus audio enable, for example, FT8 software and logging over a single cable.

Remote operation

The integrated LAN port simplifies remote control: with RS-BA1 (Version 2, optional, sold separately), the transceiver can be controlled over a network/Internet — including power ON/OFF — without a server PC in the shack. Network access and continuous DC supply are required.

Bands & variants

The European version additionally supports the newly allocated 5-MHz band and 70 MHz. Note: pre-release information; specifications may change before shipment.
