The Short Range Certificate is the minimum qualification required by law to control the operation of VHF and VHF Digital Selective Calling (DSC) equipment on any British flagged vessel voluntarily fitted with a radio. This includes both fixed and hand held equipment using International channels.
The SRC course can be taken in the classroom or online with an RYA recognised training centre. The exam must be taken at the training centre.
All new VHF sets are either fitted, or can be interfaced, with DSC allowing calls to specific vessels. If you hold the 'old' VHF licence (pre-1999) you need to upgrade your qualification if you purchase new equipment.
