You need to school yourself on some very basic electronics. Even if we told you step-by-step, it wouldn't really help without that knowledge. I'm willing to bet that the pirates (and most everyone else in here) really know their radio and if they aren't closet hams they would very easily pass the test. It's because they love radio. I fell in love listening to my grandmothers giant tube 1936 Westinghouse set when I was 7. I've been taking things apart ever since, I put them back together sometimes. Successfully even. You obviously have the radio bug too, welcome! Now start taking things apart!
