So, as referenced earlier, I am a new owner of a 320DA. Ive been boating forever on the Chesapeake as a day boater on bowlders. I will be hiring a captain for a day once the weather/boat are good to go for the season but I have so many questions and would love to start getting answers as soon as I can. My question today involves using the VHF radio. 1. How to properly dial it in or "squelch" it? 2. What channels to use and what uses for each channel? 3. How to properly communicate and maintain proper etiquette? 4. How to use it in emergency situations?
