Ship/marine traffic HF radio (BC-221).
I used to think the little 221 was a real useless piece of test gear.
Wow! Was I ever wrong.
Those things are so easy to use. And damned accurate!
I have one next to my recently restored TBW xmtr.
Great tool to have around.
But I did have to replace a bunch of paper caps in mine.
I suspect it will outlast me by a long shot.
