ICOM IC-7300MK2
The SDR Evolution Setting the New HF/50/70MHz Standard
Original Icom transceiver in the official European version (fully including the strategic 5 MHz / 60m and 70 MHz / 4m bands). Supplied with original packaging, standard accessories and Official 24-Month Italian Warranty with specialist technical support from real radio amateurs.
Product Description
HamRadioShop presents the IC-7300MK2: the maturing of an extraordinarily successful SDR platform. It is not a simple refresh, but a critical optimisation of receive performance, thermal management and connectivity, essential for the challenges of modern amateur radio operation.
The MK2 update refines the radio’s fundamental parameters: RMDR dynamic range rises to ~105 dB at 2 kHz for superb selectivity in crowded contests, while transmit phase noise drops to -139 dBc/Hz at 1 kHz for a very clean carrier. All this is combined with new built-in USB-C connectivity, a direct LAN port for remote operation without a server PC and HDMI™ video output to turn the shack into a real control centre.
Key Features & MK2 Innovations
|
Built-in HDMI™ Output
High-definition display of spectrum, waterfall, frequency and menus on external monitors or TVs for advanced visual analysis. |
Direct LAN Port (RS-BA1)
Full remote operation over the network with remote power on/off (Wake-on-LAN), without needing a PC left on in the shack. |
|
USB-C Dual COM Interface
Modern connectivity providing two virtual COM ports and simultaneous audio: ideal for FT8/FT4 alongside Log and CAT. |
RX Antenna In/Out (SMA)
Dedicated SMA connectors for inserting receive band-pass filters, external preamplifiers or auxiliary listening SDRs. |
Field Technical Analysis & HRS Usage Tips
PERFORMANCE MEASURED IN THE FIELD
- RMDR ~105 dB (at 2 kHz): Eliminates desensitisation (blocking) in the presence of very strong local stations a few kHz away. In contests or DX pile-ups, sensitivity stays intact without intermodulation distortion.
- TX Phase Noise (-139 dBc/Hz): The redesigned oscillator ensures an exceptionally "narrow" transmit signal, eliminating splatter and avoiding interference to adjacent stations.
- Thermal Efficiency & Quiet Operation: RX current draw reduced to just ~0.7 A. The new progressively controlled fan keeps the unit extremely quiet while listening and cools it effectively in TX.
?? Station Optimisation Guide
- SMA Loop for RX Antennas or BPF Filters: Connect a directional receiving antenna (Loop, Beverage) to the SMA IN/OUT port or insert an HRS-BPF band-pass filter to protect the receiver without risking damage to the filters in TX.
- Perfect FT8 / FT4 Setup: Use the dual COM via USB-C (COM1 for CAT on WSJT-X, COM2 for the Logbook). Adjust the output keeping ALC at zero for maximum emission linearity.
- HDMI Output for the Waterfall: Set the external monitor refresh to FAST in the radio menu for full-screen spectrum analysis without loading the station PC.
HRS Technical Tip: For remote operation via LAN, the IC-7300MK2 natively supports the RS-BA1 V2 protocol and the Wake-on-LAN function: you can switch it on and off remotely over the network without timer sockets or external power relays!
The HamRadioShop Team’s Opinion
"On HF every single dB of RMDR makes the difference between working a DX or losing the station. The IC-7300MK2 refines an already iconic radio exactly where it matters: slashed phase noise, optimised thermal management, LAN port and USB-C/HDMI connectivity. It is the definitive radio that will give you a real step up on the bands."
