Codan’s RC50-C HF Email software provides efficient, error-free email capability over HF radio.

Operating in conjunction with Codan’s HF Transceivers and RM50 range of Data Modems, the RC-50C software operates on a standard Windows™ PC using a single USB port with no specialised PC hardware requirements. When installed, the software runs in the background requiring no user interaction.

The RC50-C HF Email software integrates with Codan’s enhanced CALM/ALE linking system, simplifying operation and ensuring the best available channel is chosen for each data session.
