Historically, it was accepted practice to check a radio's functionality on a regular basis, typically by contacting a coast station. Modern radio equipment is more robust and may only need to be tested following maintenance work, at the start of a season or if there is any reason to believe that there may be an issue. The UK Coastguard recommends using another vessel, a marina or the National Coastwatch Institution (NCI) on CH65 for routine radio checks.
It is important that you:
• Understand when and how voice and DSC transmissions should be tested
• Can send a radio check request to an appropriate station
