From my understanding, one needs a frequency generator first to put the scalar at work. I got the magic bean two days ago and still waiting for the gentleman "Dale" to answer my email about it. Looks like the after sale service is somewhat compromised if, like me, you can't deal over the phone. I can still make it work though, but something worries me and I have to check on some postings to make sure I know what I am talking about... will be back on this later.
