Spooky2 is a low cost Rife solution, described at Spooky2. Recently at the spooky2 forum Hank Gigandet posted on how the Spooky frequency generator can be turned into a Beck Blood Purifier and a Hulda Clark zapper, as well as a colloidal silver maker at this link: Using the Spooky XM Generator in Manual Mode
It is also possible to create the zapper effect from the Spooky2 software, in addition to the standalone mode described above. See this post: Hulda Clark Frequencies + Turn Spooky2 Into A Zapper
