One of the challenges of using VHF is when discussing fishing secrets you are sharing them with the entire world.
DSC Calling can briefly solve this by enabling you to call a particular person and having them automatically switch to an obscure channel (by default #6) -but this conversation is still in the “open” and as most boats scan all the channels they will end up finding and listening to the channel you designated as your work channel. Jamestown does a good job of going into this here.
That said really the only thing you probably want to keep a secret while you are out fishing is your location -so you don’t have 100 people coming and making your life hell. From the title you can already guess the answer is DSC Position Request…or as Lowrance has decided to call it: “LL Request” where LL stands for “Latitude/Longitude”. While I have gone over some of this in earlier posts, please see below; this article will show to do this with a Lowrance Link8 and a Standard Horizon GX2200.
