The Icom IC-756 Pro III marks the culmination of the "756" series, succeeding the IC-756, IC-756 Pro, and IC-756 Pro II. This latest iteration introduces several enhancements, notably an improved Third Order Intercept point of +30dBm, which boosts performance in crowded band conditions. The real-time spectrum scope has also been upgraded, offering a mini-scope display that allows operators to view the spectrum alongside other essential menus, optimizing the user interface for efficient operation.

Additionally, the IC-756 Pro III features significant advancements in audio processing and filtering. The new programmable SSB transmit bandwidth allows users to customize the lower and upper -6dB points across three selectable settings, enhancing audio fidelity tailored to specific communication needs. The introduction of a noiseless feedback preamp reduces second-order distortion, ensuring clearer signals. Furthermore, the inclusion of a clock function displaying both local and UTC time adds convenience for operators engaged in time-sensitive communications.

The transceiver's specifications are robust, covering a wide frequency range from 0.03 to 60 MHz for reception and various bands for transmission. With a weight of 9.6 kg and dimensions suitable for desktop use, the IC-756 Pro III is designed for both portability and performance. The receiver employs a triple conversion superheterodyne system, providing exceptional sensitivity and selectivity across modes. These enhancements make the IC-756 Pro III a compelling choice for amateur radio enthusiasts seeking advanced features and superior performance in their communications.
