I have done a few clicks of research to try to find these and information on them but was largely unsuccessful. The people who want to sell them outright spend a lot of bandwidth on hype and not prices or useful information like specs and legalities.
My primary question: Do these units require a license?
the talking house units along with the ramsey units are FCC typed, as long as they are not moded
also, no lic requird, tx on FM 88-108. another option that I was thinking are the FRS freqs, but this option is more tech and may not be legal
