Hi there CG family! I am training to be an auxiliary watchstander and am wondering if you guys know of any place I could listen to marine band broadcasts online to learn from? Thanks!

You need to discuss this with either your Flotilla FSO-CM, the division SO-CM or contact the local Coast Guard station your division or flotilla supports. It would be much easier for them to give you the information on local ops/freqs, etc than trying to find it here. Just trying to help you out. You ask a lot of question on here that should be directed locally. Be glad to help if you can't find what you're looking for, though. Good luck!
