CAP 1606 – 8.33 kHz Sporting Frequencies

CAP 1606: 8.33 kHz voice channel spacing in the UK: Common sporting and recreational assignments including Safetycom

During 2018 most UK VHF assignments were converted to 8.33 kHz voice channel spacing.  From the 3rd January 2019 the CAA will be converting all common sporting assignments in the UK to 8.33kHz. This includes Safetycom.

After the conversion, all assignments will utilise 8.33kHz channel numbers, changing the way common assignments are displayed and spoken.  This document outlines the new channel references that must be used after the 3rd January 2019 (AIRAC 01/2019).  It is imperative that the correct assignments are used past this date by all users to ensure interoperability.

New channel references are highlighted in the table below.

Please ensure the correct channel references are utilised, displayed and spoken after the 3rd January 2019.
