Motorola has released a new digital strategy document titled, "A Digital Communications Guide for Amateur Radio Operators". This document outlines the brief history of the various digital radio communications modes, including the technical merits of each. It then goes on to explain why Yaesu is supporting the C4FM (4-level FSK) mode, which is also known as APCO P-25 in the LMR and public safety market place. It shouldn't come as much of a surprise that Yaesu is supporting this standard since their parent company Motorola is a big player in the APCO P-25 market. Two new digital radios will be introduced in early 2012: an HT and a mobile. An early image of the HT is shown in the strategy document. You can find Yaesu's digital strategy document on their website (Welcome to Yaesu.com) or attached to this post.
