TD, If that is a EFJ 550 it is very similar to a 557 which is just higher output power. I may have a book but I can't get to it for almost two weeks. If there is nobody that can answer your question before then I will look up the book and let you know.
I have to ask, what is he going to use the 550 for? They are bad about harmonics because of the varactor diode tripler in the final. The receivers ain't that hot either! The 559 radios are a much better unit, I have built several repeaters out of them as well as the 530's. Very dependable radios.
