SGC pioneered Automatic Digital Signal Processing (ADSP) more than 10 years ago. Internal IF based DSP is incapable of matching the performance of ADSP2 because it must devote some processor time to other tasks. ADSP2 devotes all of its time to spectral noise reduction, yielding unprecedented performance exceeding that available in top-of-the-line transceivers.

SGC have tested ADSP2 in many popular transceivers, including small portable units, and significant improvements in noise rejection have been found on every unit evaluated. The ADSP2 board adds two levels of ADSP processing and three narrow band filters which gives the user significant flexibility in choosing the processing most appropriate to the operating conditions.

ADSP2 is supplied in two versions. One for low level audio power ADSP-2 Board Low (70-11) and the ADSP-2 Board High (70-12) for high level audio power installation. Both versions contain full instructions and identify the relevant wire connections
