IARU Region 1 recommendation (2)

November 2008: IARU Region 1 re-endorses RSQ reporting and also recommends MOS for digital voice.

The 2008 Coatia meeting held in Cavtat reached agreement on the use of RSQ (Readability, Strength Quality) for digital modes and MOS (Mean Opinion Score) for digital voice communications. The recommendation was proposed by Norway's NRRL and authored by Tom Segalstad LA4LN.

The Cavtat C5 committee recommendations were as follows:

Recommendation CT08_C5_Rec15 (Paper CT08_C5_41 RSQ and MOS signal quality reporting on HF and VHF) It is recommended that RSQ (Readability Strength Quality) reporting may be used for digital modes if applicable (e.g. PSK31), and that MOS (Mean Opinion Score) reporting be used for digital voice, as a supplement or substitute to the RST (Readability Strength Tone) reporting scale.
 
Recommendation CT08_C5_Rec16 (Paper CT08_C5_41 RSQ and MOS signal quality reporting on HF and VHF) The recommendation and the RSQ and MOS reporting scales with notes should be included in the HF- and the VHF Managers Handbook.
