I still have my old "Frog-7" - it's sitting next to my bed. I've been
thinking of putting it on the boat as it is a great AM radio receiver that
will run on it's own batteries. No need to drain the starting battery!
Many years ago, I hooked it up to my C-Band satellite receiver to pick up
telephone transmissions off the satellites.
I'm wondering what type of antenna I could get that would work well on the
boat - somehow the 200' longwire does not seem practical ;-)
