My wife, Liz, and I are Amateur Radio Operators (Hams). I wanted to place a cache that honored that hobby. I also wanted place my first Mystery cache. That has turned into a series. This is the second in that series. I have several more planned or in the works. I may continue to add to it over time.
Amateur Radio is a hobby. It is governed by FCC rules. We have fun in many ways, but we also serve the community using the skills we develop. Many Hams contributed during the two recent storms Irene and Sandy. I hope while you research this cache you will learn a little about this hobby.
For this cache you will have to answer questions that are presented on the Technician class exam.
Coordinates for the final will be in the form: N41 ab.cde W071 fg.hil
