If I were you I'd tell your wife that she should respect your hobby and ask her to refrain from interfering with your business. I don't like getting side tracked from the specific topics that this forum is supposed to deal with but reading this just makes me shake my head in disgust. I am probably at least a couple of generations in the past but I never saw this behavior in my family while I was growing up. Men were in charge of the family. Not attacking you personally but I see these kinds of posts so often on the internet it leads me to believe the men in this country have become wimps. Glad I am not married now and will likely never get married unless I can find a woman that is willing to let me be the man in the relationship.
BTW Part 15 Engineer Please keep posts such as this where you are trying to sell items to the forum at the LPAM Network site. This site is devoted to more specific topics related to the Rangemaster transmitter.
