Since that time, other researchers such as Mike Coletta have figured out how to alter the older version 12-470 AM/FM radio, too.  Mike has posted many of his videos on YouTube to help others make their own ghost boxes.  What has been great is the fact that so many have made their discoveries and research public, such as Frank Sumption, Joe Cioppi, Bruce Halliday, Steve Hultay, Sum Duc, Mike Coletta, and more.  Links to their websites are at the end of this article as a big thank you.

The ghost box can be used for EVP, as it can be recorded, then analyzed for messages from spirits and ghosts.  However, what makes the ghost box unique is that it can be heard audibly through either an external speaker or headset, where responses from the other side can be heard and responded to live – not unlike chatting with someone by walkie-talkie.  It does require the user to train his or her ear to hear the messages that are brought forth, as the noise and audio bits can at times be somewhat distracting.  But if one experiments long enough with a ghost box, it will become apparent that the audio sound bites and white noise will begin to be manipulated to form answers to questions, phrases and more.  For this reason alone, we recommend recording all sessions and listening to them later.  Upon playback, one might be amazed at what is captured in the audio.

The function of the ghost box and how it works seems to be affected by the strength of radio signals in an area.  Poor signal quality reduces the ability for spirits and ghosts to make contact through the device.  Perhaps there is not enough audio bits to be manipulated successfully for real-time communication.  That would indicate that enhancing the antenna on these devices could improve results by the researcher, according to Bruce Halliday.
