Shorebased: VHF Radio ~ 'Short Range Certificate' 

 

 

 

Syllabus for the short range certificate in detail

Aim: "The Short Range Certificate (‘SRC’) is the radio operator qualification which authorises the holder to operate a VHF radiotelephone, fitted with Digital Selective Calling (‘DSC’) on board any British vessel which is voluntarily fitted with radio equipment. "

Please note (From PTUK): When you read through the syllabus the first thought is how on earth does that get fitted into one day. Thankfully it does and actually whilst a busy day the course works really well.
