First version released in 2010 had standard FM & AM channels
2nd Version amplified the FM channel and Detuned the AM channel. Making the AM less noise and quieter.
Rev. 3 brought back the amplification and tuning in the AM and normalized the FM channel. Also had a new chip in the unit swept down to lower frequencies.
We are now at Version 4 (2018).
“The Original Spirit Box was created by Gary Galka (engineer) and myself, Chris Fleming (Medium and Paranormal Investigator). Which is why I sell it on my store, Ghost Outlet.
I first introduced the demo model of the P-SB7 on Ghost Adventures live in 2009 and have captured some of the most remarkable ITC communications in my lifetime. I personally love the AM mode, but occasionally use the FM mode as well. In 2010 we released the PSB-7 to the world as a commercial unit.
The term Spirit Box and SB as well as the number 7, were spoken and given during a session with the original demo model. The Question was asked, “What should we call this device?” The response almost immediate was Spirit Box! During a later session, it was asked, “What number should we use with it?” The response was in the likes of, “Seven, eleven, thirteen, …Seven, Seven…….SB7!!!!” Surprisingly the voice coming through named the device “SB7” which is what we call it today.
I do know The FM frequency sweep method has clearly become the preferred technique used by Zak on Ghost Adventures and is used by paranormal enthusiasts worldwide.
As an avid ITC researcher, I do recommend anyone getting this unit if you want a great ITC device to hold in your hand and capture DRVPs.
You can use the MP3 external speaker that comes with it or upgrade to your own high-quality external speaker. I use the Altec Speaker or JBL flip 2 during all my sessions while I record most of them with my H4N Zoom recorder. Later loading on my computer for playback, marking, and analysis. “
