  I ran across some additional information related to this topic this morning and thought I would share. This confirms the previous article (and information that has come from the ARRL). What are your thoughts?

  There’s also an exemption for devices built by a user for personal use:

  I would like to do a club meeting program where we test spurious emissions on people’s HT’s. I think it would be a lot of fun and everyone can learn a few things. I’m working on the details for that.
  
  You can find the procedures for a spectral purity test here:
