Hi All Do we have any radio hams on the list? Where can I get information about the 433 MHz band licensing requirements? I've tried the FCC page, part 15 etc, but ended up more confused than when I started. I'd like to find out: 1. Is this a licensed band in the US? 2. Is it classified as usable for ISM applications? 3. What are the requirements for licensing at this frequency in the US, if any? If someone could point me in the right direction to get the info I'm looking for, I'd appreciate it. This message was sent originally with the wrong heading. (forgot the semicolon) I appologize for that. Thanks in advance Fritz -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
