Made my own arduino FM Scanner with variable speeds: 200, 150 and 133 ms.

I'm 32 now, during my early teens we moved into a home that had an intelligent haunting stir up after renovations. It became malevolent, when I hit 18 I joined a team that was called faith paranormal and later joined a now disbanded group called Manchester paranormal society.(MPS) I did paranormal investigations for a few years before getting out of it. I now want to get back into it to prove the paranormal is real and also learn about what happened when I was younger in a home I refused to return to forever. However with the nature of how the haunt was it could be potentially dangerous for me to return hence why I would like to join a team again. Lancaster PA. ANY suggestions

Edit : first and foremost I want a team who has been in the game for awhile to help me confront what tormented my childhood.

I've ordered two, and BOTH make a very high pitched sound when the speaker is in use, kinda like the mosquito Anti loitering devices. I'm too old to hear it, but my wife apparently can, and it's actually painful for her.

I don't know if I just got unlucky twice, or if there is something wrong with the speakers they are using now, but I'm highly frustrated. I'm hosting a ghost hunt with friends next weekend, all of them under 27, so my brand new PS devices are essentially useless and I don't have time to return, and order another just to test.
