Agree with use as backup
I second the idea to keep as a backup. My 1989 Ericson came with what is probably the same Sitex LORAN, which I admit is a bear to figure out and use, especially if you want to program in waypoints and routes. So I bought a GPS as well. But it is dead easy to bring up the Lat and Lonon on the Sitex, which is all I care about. when making a passage I keep them side by side and compare fixes. If they agree fairly closely I feel a lot better about knowing exactly where I am.I like having the LORAN as backup so much that I even spent $125 about 5 years ago to have the chip replaced after the internal battery died. Which, by the way, is probably what is wrong if your unit will not boot up and get a fix.Steve Christensen
