When I purchased my boat it had a marine radio in it. I thought I would not ever need that and took it out.:embarassed: I have been stuck on the water twice and had to troll home:sad2: last time my cell phone was dead and it took 6hrs. to get to the landing! I have since reinstalled the radio but don't really know the rules or anything else about it. Are there specific channels for certain lakes or is it a buddy system? What are the emergency channels? What should I never do? :smile2::smile2::confused2: What kind of range do these radios have? Lastly............who is gonna come get me next time?:smile2::smile2: JK (I won't need it now that I have it) Any help would be appreciated.
