Which Icom SDR is Right for You?
While both radios share the same iconic form factor and intuitive touchscreen interface, the internal upgrades in the MK2 version are designed for the modern operator.
- For the Digital Enthusiast: The transition to USB-C with Dual Virtual COM ports means you can finally say goodbye to complex setup cables. The MK2 handles CAT control and audio on a single cable.
- For the Remote Operator: With built-in LAN support, the MK2 no longer requires a "server" PC to be tethered to the radio. Operate directly over your network from anywhere.
- For the Serious Contester: The 105 dB RMDR ensures that when the bands are crowded, you can pull weak signals out of the noise without the receiver being overwhelmed by nearby stations.
