We get it in the Bahamas
. There is a station in San Juan
PR. All broadcasts are in English
so no problem there. Range of reception
is supposed to be up to 400 miles, although I've never tested that.
Basically you just turn it on and leave it on. It automatically receives broadcasts (messages) and stores them in its memory. You go through the message list and pick out the ones you want to read.
I like it. Since you got it "for free" I would keep it and use it. If you google
"Furuno NX-300 manual" you could download it free. Most of the information in there should apply to your unit. Its definitely worth reading. Navtex is not just weather
data. But on your units menu you can turn on or off the kinds of data you want. We only use it for the NOAA offshore
