Mods - Icom M700

The Icom M700 is a legend. Built like a tank for the harsh marine environment, this 150-watt HF SSB transceiver was a staple on commercial vessels and cruising yachts for decades. While its rugged build and powerful output are still revered, the stock unit is showing its age—especially for amateur radio operators (hams) who acquire surplus units.

The Icom M700 is not a SDR (Software Defined Radio). It won't give you a waterfall display or a narrow roofing filter. But for the price (often $150–250 at swap meets), you get a 150W transceiver with a receiver front end that rivals radios costing ten times as much. icom m700 mods
