Hi I've been experimenting with this bit of kit for a while and have been talking matters over with another member here. Today I direct connected it to my computers microphone socket and via a adaptor linked both circuits together. I then used mic boost and live monitor. I was surprised how untroubled by electrical noise it was. I test for sensitivity by touching the short antennas which causes a rise in the buzz during the day but at night you will often here Strong short wave broadcasts! This test was made in the day. I ran it through DC Live forensics, used anti buzz filter as there was a 50hz hum and then used an exciter and normalise to human voice. What I seem to have captured is the sound of a steam train LOL appropriate for me as I love them and am a train driver as well! Anyway, more importantly there are even to my ears the sounds of voices, and one has a tone I recognise! Maybe some of you more experienced listeners will hear words?

Hi, just a tech note (James?) our diode box builder has used a 10K resistor between earth and diode output, but most of the circuits I find on line say 100K, this is quite a difference and would I think make the box far more sensitive, using the 100K that is. Comments?

Hi OK, I have done some more work with this unit today. I connected it to the mic input of a mixing desk that also includes slider controls for amplification, I then took the output of that into the Line in of my Zoom H2 digital recorder. At home, I found there was a dreadful lot of buzz and interference pickup. So today I took the whole set up away to a woodland location and set up in the car. I was amazed to be able to use full gain on the mixing desk, that's 10 where as at home I can't go above 4. I then took two recordings, one with the device on the dash and one with it on the roof. This is the one made on the dash: http://shareplace.com/?C310C1E117 and this on the roof: http://shareplace.com/?66CB085723 There are some interesting noises such as mic bumps, which of course are impossible as there was no mic connected. Don't think there are any voices but have a listen and see what you think.

This time I think I have something! I came home on Sunday after visiting family to find our street in the middle of a power cut. As my diode radio is now fully battery power I thought it would be an ideal time to try it out at home. I was rewarded with clear mains hum free reception. Recorded with my Zoom H2 digital recorder. Have a listen to this clip. I hear the same phrase repeated six times at: 11.07943 49.60066 01:01.59168 01:08.51753 01:47.17825 01:51.00297 http://www.box.net/shared/o9vj8mqycf There may be more. So what do you guys hear?

Hi everyone OK, I have worked on the file myself and produced this. http://www.box.net/shared/l492g9017c I applied a brick wall filter to remove some of the hum and a bit of hiss. Then a custom continuous noise filter followed by a sectionalised gain increase. I am very interested in these two time frames: 48s.6 and 1m-45s.6 where I hear the same phrase. The phrase is present four more times but these two seem the best example. Be great to hear your thoughts. Mike

Just noticed that these were "different" uploads than what I had thought they were. I am downloading to see if I can hear anything. I don't know why he has changed the resister so much...seems as though 10K is plenty sensitive enough with the SW coming in at night. I don't get any kind of interferance where I am located. I thought once maybe I got some trouble from my cell phone. But I need to check again. Just a tiny-short "rushing" sound. I need to try it during all phases of the call and ending to be for sure. Could have been something magnetic through the sunspots though Jim EDIT: Talking about the 7th post. Last edited on Mar 9th, 2011 08:27 PM by clockdryve |

It is actually a small version of a conversation going on from 34 to 44 seconds. I have LOOPED this smaller part to help pull out the female voice. I cannot understand what is said seconds before this voice, maybe instructions from a male voice, because I hear him speaking in 3 areas between those few seconds....female voice was last-just before the "blip" NOTE: when you are in an area that allows you LARGE amplification "not much QRM/QRN" (interferance) ....AFTER recording you can really slam it with a lot of amplification....*UPLOADING to PC (amp it) or while using your Audio Software during PC playback (amplify the complete recording) allowing the base band audio signal to be "as large" or a little larger than the height shown in these CAPITAL LETTERS. I'll show example. This is when you are using the Raudive Diode Receiver mostly.... because there isn't anything else in the way for distraction (much). NOTICE: This upload I sent here of the female voice is very quiet... It is the actual true volume of your recording...highlighted by looping only. I will include a version showing the allowed limit (close) to were you can amplify the file after (or during) upload to PC. *while you are working with the file to find the EVP's* I hope this is not confusing... what I am trying to explain. You should download and possibly "amp" this attachment "show_me....." to a level of volume you are more comfortable with.... but I wanted to show it's natural volume level so you can pinpoint the voice in your original recorded capture.....

Seems that with the Diode Receiver that many of the voices will be very weak... But I am still very new to the Raudive recordings myself...and I HAVE found a few that could be easily amplified to understand them well. I will review more of your file now. I will need to continue for completion tomorrow, as it is about 11pm at the moment.

Here I have taken this last example and ran it through a lowpass filter (cutoff frequency of 1310Hz in Audacity-is what I use all the time) Main thing I want to mention here is that the multiple "thumping" is something that is OFTEN associated with many EVP captures...and you have a good example in this area where the female voice is present. I didn't need to allow for the filter, but I just included it here to make it easier on the ears. You will not always hear this thumping though...but it is very common at times. I suppose you might know these things....but if not---and for those that are NEW. Attachment: approximately 34 to 42plus seconds-lowpass-filtered.mp3 (Downloaded 1342 times)

I hear "what ever you say". I missed it the fist time I listened but ran it through a program called "Denoiser" that the DEMO version was offered to me by a Lady from this forum...and it has a "special" CUSTOM setting (also sent to me) that she said was directed to her by some of her spirit contacts. What ever they told her to do has amazed me at times for sure... After you hear these modified versions you might be able to pick it up just slightly in the original capture just after the thump. You might want to download and amplify. It is in there for sure. Attachment: 1st thump-audacity_CLR.wav (Downloaded 945 times)

Here is the same area clipped (no main thump) and looped to allow to hear it better possibly. At times here I think I hear it as "my memories set" but not sure because I don't know the voice (male). *you will hear a slight "thump" but that is because it was clipped away from the full length...and that causes a distortion that is amplified in the looping.

Mike I wonder if these antenna's can be improved upon. Seems like we need to amplify the signal as it's discovered I don't think making them longer is the way to go (maybe) But I have been thinking of "directional" BEAM possibly. ?? This has been on my mind for a couple months I don't imagine a wide band "signal" pre-amp will do anything for these passive signals...so antenna can work to near passive. Electronic amp will just increase the hash anyway so no real gain there I suppose. Last edited on Mar 9th, 2011 11:48 PM by clockdryve |

Wow, such a lot of work Jim thanks. I still find it hard to hear and I feel strongly that a better method is out there. As to the antennas, I feel they need to be more than what they are. Some kind of coil is needed, something that resembles a mic head but not LOL Look for example here: http://www.instructables.com/image/FUGXU4EFYTCLHEW/Testing-the-AM-Radio-Circuit.jpg and here: http://3.bp.blogspot.com/_fbCGoSyYfBw/SSmrF-zYwpI/AAAAAAAAAFM/CDUNVkT-wSI/s400/raudivediodercorderschm.JPG I feel very much that a loop is the way to go and I shall be looking at this soon. Of course, what we must do is take away our 'radio' knowledge as I don't think it counts for much here. What we need to do is be guided by our own intuition or that of spirit if anyone can help with that. I'll be posting the results of my earthed test a wee bit later.

Yep, I was thinking along the lines of a loop also...but I kept thinking more like the form of a "spiral" antenna (like used in some satellite reception), but I knew that wasn't right. Ive purchased some "sound powered" headphones from eBay....hoping that the large coils and balanced armatures will be helpful in amplification of the end results. Back to the coil...I think there is a guy (maybe called frank) online that has been experimenting with a couple coil forms over a ferrite rod. ?? Maybe you can focus a parabolic onto a " large coil" (many wraps of small wire). You could use a WOK lid as a reflector...many are using similar settup for wifi antennas. But I don't know what actual frequencies the spirits are using to adjust for an efficient "parabolic" reflector. Some think the reason we get "weak" captures is because we are receiving the actual "harmonics" of their actual speech. But that doesn't really sound right because I have received a few that were as loud or louder than my voice. Last edited on Mar 10th, 2011 09:20 AM by clockdryve |

Nice video Mike. You have a nice calm voice I think you music choice worked very well with this video. I have the Zoom H4 recorder. I like the size of the H2 better, but I was able to get a good used H4 on craigslist.com for a very reasonable price... Well I'm taking off for awhile...be back this evening. It is 10:32am at the moment. See Ya

Yep, looks good. Nice that you don't have interference out in the garden!! The more you try to record back there...the "hotter" the site will become. I know this from personal experience. And I have read that too. I had a very active (single) location in back yard of where I lived last year. "VERY" good location it became (I miss that place too). Haven't had time to listen to your STE-001 file yet. Really only found those few areas in the STE-000 (hope was the file name) *away on mobile phone right now. Heard a touch more in a few other places but I couldn't understand what was said. Truthfully...the ones I uploaded were extremely weak to hear. Will get to your other (recorded from the country-car) later on this evening when I get back home. Question: Do you ask questions (and wait 15 seconds at least for answers)...while you are recording with the Diode receiver? Have you tried using the H2 alone as a recorder "only" for your question (no diode connection)... Seems like often get better results when we associate with them. Talk later. Cheers

Hi I regard this phase as very much a 'test' for both myself and the spirits. So usually I simply request they draw near, I specify those that I am seeking and ask them to seek assistance their side to cause an impression. All I ask for is confirmation they are there and to try and make an impression on the recorder system. Yes I have used the H2 alone, its very sensitive and I once spent hours and hours cleaning a file only to find I had captured a dove some distance away LOL This Clear Voice Denoiser, I tried the demo and quite like it, trouble is you can no longer buy it! does anyone here use the full version and ahem would not mind helping me get rid of the silly 30 sec max? Off to bed now, Jim lets try and come up with a antenna that meets the criteria of minimal material yet better capture.

Hey Mike, Looked over your file STE-001 and the only thing I could find was the voice of a small child...possibly a little girl of about 5 years old. She seems to speak somewhere around 9 syllables... But I can't make out what she is saying. Here voice is found in the original file at around 2.31 to 2.39 minutes, and can be heard on this upload at around 1 second to half past the 5 second mark. You might be able to hear the voice...but it's going to be very,very weak. Just keep trying with the Diode Receiver and eventually your odds should improve. Don't let it become a "job" though....keep your spirits light I'll be around.... Cheers.

mikesndbs wrote: Hi Yea, I wish I had the full version of the Denoiser too. But it works pretty good as a "final" approach to polishing up the EVP clip. Or to be used where you hear the voice but can't quite make it out.... But it's not fool proof....some will not be able to be decoded using it....but a free try And 30 seconds it usually more than enough to enhance a difficult EVP that has been clipped from the main recording....since they usually are only a few words in length. While I'm thinking of it...here is one of my better captures using the Diode Receiver. I have amplified it and looped to help hear it easier...it's definatly a female voice. Kind of "eerie" in a way....because she asks "who are you"? ..... "were watching you" But it isn't the part that says "were watching you" that is bugging me..... It's the part where she says "who are you"?? Because I have had MANY voices from the Spirits and they already know my name This one doesn't know me.....but can see me. I'm pretty proud of this capture though.... It is quite mysterious and personal. Attachment: who_are_you_were_watching_you-denoise-evp_CLR-3.mp3 (Downloaded 938 times)

I looked over some new reading material on EVP"s. As a PDF file. I will get the link off pc later and forward it. It didn't have any directions or anything on this one subject...but it mentioned that it would be helpful in building a directional gain antenna to aid in possibly enhancing communications with the spirit world. Just kinda woke me up a bit. I just purchased another Raudive Diode Receiver last night on ebay. Cost of $15 including shipping!! Has a full aluminum 2 part case with 4 screws. That instrument I will be able to adjust for antenna's much easier. Only one channel though. Well gotta run for awhile. Good Day

Yes, a all metal case would be a real advantage, I am thinking of making one myself, I have a metal case needing a job. $15 is far better than that other one, who still has not answered my emails!

Quick thoughts: I can't help thinking that the further we refine towards what should work for radio, the further we are moving away from what might work with spirit. I have scanned the bands from 50 kHz to 1300Mhz since the 80's and never have heard a spirit voice (that I know)

Here is the picture of the receiver from ebay. What caught my eye was the inductor "coil" being used.... Looks like he is using a rather long antenna on this one. Included also is that CD on Raudive Recordings also. I don't think that external switch is connected. I will put a microphone on/off momentary pushbutton switch on it anyway. And include a couple different types of microphones...maybe actually use that switch for a full time microphone on option. Maybe EVP require simply "passive" types of reception....as close to natural as possible...without any, or to much artificial filtering at the first point of contact. ??? A directional beam of some type might amplify if it (voice) is larger than a single point wave. To much unknown right now ;) Attached Image (viewed 1789 times): Last edited on Mar 11th, 2011 02:44 PM by clockdryve |

Hi Mike, I'm no tech whiz by any stretch of the imagination, all I know is what I can hear and this clip is loaded. The very first clip you posted. So here is what I can hear in that clip. It is a very hard one so there is a lot I have missed as static. First the loud thump/pop, .12, and I don't know when I can do that, .16 No problem guys I'll see you later, .24 you'll lead to it, .28 John Carson here, .32 Bobby, no one else can hear you, .35, I've been lonely, .40 Dad's with me, .43 Don't go there, Dad's not there. He's with me Junior, .50 Cathryn's there, I told you she went there Calvin, 1.00 I love you, I love you so much ______ to come and see you with your mother, 1.05 We're allright don't try to call, 1.06 I don't know the ______ life is, 1.11 Come on Gary how short their life is, 1.15 Do you want to be my friend, 1.20 She calls sometimes I'll take her, 1.26 perfect group????(not sure about that) 1.35 sounds like singing???? then I should have told you/her, 1.47 Wake up Joey/Joe he lies down here 1.52 Hey Punkin thats me but she doesn't know it, 1.59 Love you Mary. Well there you go, see if you can hear any of that at all. There's a lot more stuff in there, I just couldn't hear it all. It overlaps as most of them do. Thanks for your time, Debbie

! good lord Debbie! Amazing stuff and of course I am desperate for the 1.00 bit to be for me. I just can't hear anything. A lot of the things you hear seem to be American accented, which seems odd as I record here in the UK and have not US associations on the other side? Please keep checking my files out when you have time, I am most grateful for the input. Mike
