I have a few loran couplers laying around, some trimble, northstar, TI,
possibly a SI-Tex. I could give you one for the price of shipping if you
want. Don't know what model Loran your looking at, some couplers
interchangeable, some not.

3. If you have a marine LORAN which does in fact need an external coupler
to get enough signal through and you don't have the companion coupler
unit, are any commonly available pre-amp boards for the LORAN frequencies
available? If so, where find?
