NOTE: The Mind Justice organization, headed by Cheryl Welsh, was at one time "CAHRA" (Citizens Against Human Rights Abuse)

Mind Justice would like to express deep gratitude to Eldon Byrd for his efforts to conduct and report on this experiment. Dr. Byrd had to deal with a 'token budget' and donated numerous hours that added up to days, then weeks of gratis work. He made an open-minded commitment to learn about mind control by attending conferences and meeting with several victims, plus reading extensive background information and documentation. He was forever patient and sympathetic to the numerous pleas from victims for help and relief, never one to judge, concerned that yes, definitely something was going on, deserving of long overdue scientific study.

Dr. Byrd is risking his career by going public with his work; what other scientists are willing to tackle mind control, a subject fraught with national security issues and attempts to keep the subject black. And now, Dr. Byrd has felt that he has done all that he can for victims and MUST go on with his life! PLEASE consider the tremendous effort Dr. Byrd has made and keep in mind his wish to earn real money for his valuable time.

Here is Dr. Byrd's year's worth of groundbreaking study, truly a gift of compassion and sacrifice. Thank you Dr. Byrd!



Thanks to Cheryl Welsh and CAHRA for sponsoring the experiment, Henry Dakin for providing spaces for conducting the experiments, Fred Sicher and Dr. Jon Klimo (Professor at Antioch University) for providing the equipment used and their expertise in helping establish protocols and helping conduct the experiment, Eleanor White for the Figures, and to the subjects who traveled great distances and shared their time to be tested in the first serious attempt to bring science into an area containing mostly anecdotal evidence


C.A.H.R.A. (Citizens Against Human Rights Abuse) commissioned me to conduct an experiment in San Francisco, California on February 9, 10, and 11, 2002. The purpose of the experiment was to gather data similar to existing data that indicated it is possible to record voices heard by some victims of mind control. Although it was considered a long shot, because only one victim had been successful in recording the voices, it was deemed worthwhile in case other victims' voices were produced in a similar manner.

The successful recordings were made by Fred Sicher. It took many sessions before the voices became intelligible. They appeared to be mostly children being sexually abused. The recordings were made near, but not on the head. The raw data was amplified by use of a graphic equalizer that reduced the noise, enhancing the intelligibility of the voices.

Although the experiment was not specifically designed to test for the method that might be used to induce voices the subjects reported hearing in or near their heads, it is worthwhile to note that 'microwave hearing' has been reported in the scientific literature.

Dr. Robert O. Becker, in his book, The Body Electric, Electromagnetism and the Foundation of Life, 1985,
William Morrow Pub. p. 319, states:

"In the early 1960s Frey found that when microwaves of 300 to 3,000 Megahertz were pulsed at specific rates, humans (even deaf people) could "Hear" them. The beam caused a booming, hissing, clicking, or buzzing, depending on the exact frequency and pulse rate, and the sound seemed to come from just behind the head. At first Frey was ridiculed for this announcement, just like many radar technicians who'd been told they were crazy for fearing certain radar beams. Later work has shown that the microwaves are sensed somewhere in the temporal region just above and slightly in front of the ears. The phenomenon apparently results from pressure waves set up in brain tissue, some of which activate the sound receptors of the inner ear via bone conduction, while others directly stimulate nerve cells in the auditory pathways. Experiments on rats have shown that a strong signal can generate a sound pressure of 120 decibels, or approximately the level near a jet engine at takeoff. Obviously such a beam could cause humans severe pain and prevent all voice communication. That the same effect can be used more subtly was demonstrated in 1973 by Dr. Joseph C. Sharp of the Walter Reed Army Institute of Research. Sharp, serving as a test subject himself, heard and understood spoken words delivered to him in an echo-free isolation chamber via a pulsed-microwave audiogram (an analog of the words' sound vibrations)beamed into his brain. Such a device has obvious applications in covert operations designed to drive a target crazy with "voices" or deliver undetectable instructions to a programmed assassin."

Dr. Becker, in a telephone conversation in March 2002, mentioned that he has been contacted by many victims of Mind Control over the past several years. He was adamant that the only way to find out what may be going on with them is to conduct scientific experiments, such as this one.

An Audio Spotlight Creates a Personal Wall of Sound


A person hears a voice in her ear, turns around and sees nobody there. No one else has heard it. Or she hears footsteps in a room, the product of an invisible presence. Is her mind playing tricks on her? Or is it a jokester, F. Joseph Pompei? A 28-year-old graduate student who is part scientist and part showman, Mr. Pompei has invented a device that projects a discrete beam of sound in much the same way a spotlight projects a beam of light.

The audio spotlight, as Mr. Pompei has dubbed it, emits a column of sound enveloped by silence, the way the glow of a spotlight is enveloped by darkness. Someone standing inside the beam emitted from his flat black disk hears the sound loud and clear. Outside the beam one hears silence or, if there are surfaces nearby, faint murmurs from the reflected sound waves. The beams can also bounce off walls to create an impression of the source of the sound. Companies are already dreaming up commercial applications for the beam. Supermarkets and retail stores may beam product enticements at customers. Vending machines may soon talk as people pass by. Dance clubs could divide up a single room into different music zones. Daimler Chrysler is looking into installing sound beams in a truck so that passengers can listen to their own music. The military could use it to confuse enemy troops. American Technology Corporation, a San Diego-based company that makes a similar product, has already sent out evaluations to military contractors, consumer electronic manufacturers and entertainment companies. It has signed a deal with the shipbuilder Bath Iron Works to install the sound beams on the deck of a new Aegis-class Navy destroyer as a optional substitute for radio operators' headsets. As for consumers, Terry Conrad, president of ATC, estimates they will start being hit by sound beams within two years.

Now sound can be personal without any apparatus shielding our ears. Mr. Pompei gets letters and e-mail messages from around the world from people convinced that his audio spotlight is being used on them as a mind control device. People have written Mr. Pompei asking for devices to shield them from the audio spotlight's insidious mind control uses. The sound, reportedly, seems like it is in the person's head.


There is ample evidence from the literature that the military and other organizations and researchers have developed and demonstrated technologies to induce voices in peoples heads. The existence of such technologies provides a rationale for conducting scientific experiments such as this one.


The hypothesis that CAHRA wanted to test was that the voices are produced by technological means, and are not the result of mental illness on the part of the victims. The experiment was not designed to test for mental illness. The resources available did not include the ability to detect radio carrier waves that may have been used to target the victims. This experiment was restricted to only the recording of acoustic auditory sound waves near the victims' head.

Recording Environment and Equipment

Initially, a Faraday Cage was to be available; however, at the last minute it was not, so four spaces were used in an office building in San Francisco. One space was a sound proofed room, another was an open area, the third was an empty office suite, and the fourth was a quiet space (no air conditioning ducts) in a storage area.

Equipment available included the Blue Mouse microphone, two small lapel microphones that were fitted into the Stanton high quality earphones, two microphone preamps, a high quality digital audio tape recorder, an analog tape recorder, the commercially available Tri-field Meter, and a boom box for analog playback. Several trials in the sound proofed room yielded no results, so that space was abandoned.

Subject A

Subject A is a 35 year old male from Philadelphia, PA. He has a college degree in Graphic Design and works for a publishing company. Subject states that he first started noticing pains in the back of his neck and in the region of his heart in April 1993 while a student in London, England. After returning to the US, voice transmissions began about August 1993. Subject reports that in addition to the audio, he experiences various forms of torture. Subject reports traveling between the US and China and Russia. The voices follow him no matter where he goes.

Subject B

Subject B is a 46 year old male from a military family. Subject graduated high school and attended college, but did not matriculate. Subject spent 18 years in construction, and is a motorcycle mechanic. He was co-owner of a Doberman breeding and training business. Subject began hearing voices about 1993.

Subject C

Subject C is a female and mother of two, residing in the Midwest. Subject began hearing voices as 'whispers', saying things like, "She hears us." The voices seemed to be coming from just behind and above her head.

Subject D

Subject D is a female, approximately 40 years old with a college degree in Law. Subject reported she started hearing voices in 1988.

Subject E

Subject E is a communications expert with a solid background in work with various agencies. He started hearing voices about three years ago. Subject has been located in CA since before the onset of the voices.


Equipment configurations for various recording setups are shown below as figures 1 through 3. Also Photos 1 through 5 shows the equipment as set up to record data in the vacant office suite use for most of the runs. Photo 1 shows the Blue Mouse microphone mounted at the focal point of a parabolic reflector. Photo 2 shows the headphones with ear microphones in place. Photo 3 shows the pre-amps, DAT, and boom box. Photo 4 shows an over-all view of the equipment setup. Photo 5 shows the equipment setup with one of the subjects in the approximate position used to record most of the data.

The tape counter on the DAT was used to determine the length of each run and to provide fiducial marks necessary to return to the beginning of each run to listen to the results.

Location of each set of runs is as noted in the section "The Trials". The equipment operator, myself, and a PhD psychologist were the only persons allowed in the rooms when recordings were being made, except for some recordings made in the open area late at night, when one other person was allowed to watch. The purpose of the psychologist was to be a witness and to offer expert suggestions. Also, he was familiar with the equipment and had been present when the original recordings of the voices in the equipment operator's head were made. The equipment was jointly owned by the operator and the psychologist.

Each subject presented a different modality for their experiences with the voices, so an absolutely rigid set of protocols covering all the subjects in the exact same way was not possible; however, the recording techniques varied only within the established equipment configurations as shown in the figures, and the placement of the Blue Mouse Microphone.


All runs for Subject A were made in the vacant office suite.

The first two runs for Subject B were made in the office suite, the next four in the quiet space, and the balance were made in the open area. These were conducted late at night and only those involved in the experiment were in the building.

All runs for Subject C were conducted in the office suite.

The first two runs for Subject D were conducted in the office suite. The final six runs were conducted in the quiet space.

The first four runs for Subject E were conducted in the quiet space. The final five runs were conducted in the office suite.


There was a lapel microphone in each ear of the Stanton headset. There were only two channels available on the DAT recorder, even though each microphone pre-amplifier had two inputs and two outputs possible. Thus, either both ear microphones or one ear microphone and the Blue Mouse or the Blue Mouse in binaural mode could be recorded simultaneously. See figures 1,2, and 3 for the various configurations. The earphones were selected because of their sensitivity, wide bandwidth, and the large earpieces that completely covered the ears with a large rubber ring. The cables for the ear microphones were secured to the rubber rings with electrical tape, while the microphones themselves dangled into the ear cavity of the headset, about midway.

The pre-amp had a phase reversal switch and a 24Hz roll-off filter switch. Unless otherwise noted in the section on the Sessions and Runs, the roll-off filter was not employed, and the phase of the input signal was not changed.

The DAT recorder had the capability of tape marking in order to return to a particular spot; however, it was noted that the marking was approximate, so the marker numbers are not included here, even though they will be used to return to specific areas of the tapes for further analyses. The DAT had both balanced (XLR) and unbalanced (1/4") inputs. XLR connectors were used exclusively, even though the output from the lapel microphones employed a 1/4" to XLR adapter. The DAT recorder could record in 16 or 24 bit format. 16 bit was used throughout the sessions, because 24 bit recording mode reduced the recording time per tape by one half, and there were other considerations having to do with the recorder having been set up (switches, buttons, etc.) to successfully record the voices in a previous subject's head.

A good quality 'boom box' was used to listen to the recordings as they were made. Actually, a less expensive tape player was better in some respects, because it limited the frequency bandwidth of the sounds, eliminating some of the very low and very high ambient noises. However, the reason for using the higher quality unit was that it had a 5 band equalizer built into it. Many cheap portable players also have some equalization. An alternative, even better arrangement would be to use the multi-band equalizers found in most component stereo systems. This allows for the filtering of various noises on the recording and thus, bringing out the voices more clearly.

Note that the Blue Mouse (Figures 1,2,and 3) fed into the DAT recorder and was COMBINED with the ear microphone pick-up via a feedback loop (BM to DAT, DAT output to headphones, ear microphones to DAT, combination to headphones).

The Blue Mouse was mounted at the focal point of a parabolic reflector in order to enhance its collection of subtle sounds.

One configuration that was not used was to place a microphone directly touching the subject's skull. It is possible that the induction of voices into heads will resonate the skull and this can be picked up when there is no audio in the room or in the subject's ears that would be picked up by the scheme employed in this experiment.

Note: all microphones have a preamp between them and the DAT and/or analog player/recorder. The analog playback was used to listen to each recording after it was put onto the DAT. It was necessary to unplug the analog player before each DAT recording run, because audio feedback would be produced due to the feedback arrangement between the microphones and the earphones.

All subjects were placed in a sound-proofed room and asked if the voices were louder, the same, or muffled. All reported that the voices were the same, muffled, or had vanished; therefore all runs were conducted in one or more of the three non-sound proofed spaces provided to us.

All subjects reported that the voices were active during their session. A sound check (control run) was conducted prior to the commencement of the sessions. Unless otherwise noted, the Blue Mouse (BM) was positioned approximately 3 feet from the front of the subject's head. The only enhancement of the tapes possible with the equipment we had was to play the DAT recordings through the Boom Box with its equalizer set to reduce ambient noise, and boost the gain. The new analog tape recorded on the Boom Box was louder with less noise than the original. This was how Fred Sicher processed his tapes.

Subject A:

After every communication from the voices, the subject would say 'stop'. The DAT was run back to the beginning of the run and played to determine content. Subject reported that the voices were louder than they had ever been. Subject reported no unusual sounds other than the normal ambient sounds in the room, except for an occasional, but infrequent, 'popping' noise. Subject reported that sometimes the voices would take control of his vocal chords and vibrate them to approximate the words he was hearing. (Note: other victims have claimed the same thing. This may be a rather common occurrence for many of them). Therefore, careful visual monitoring of subject's throat and mouth was conducted during every run. During some runs, the subject's thyroid glands seemed to be moving; however, subject's Adam's Apple never moved and his mouth was always closed. It is impossible to enunciate words with the mouth closed. Subject reported that the voices were sometimes in his head and sometimes external. In general, he said, there was no difference in quality between indoors and outdoors. Subject stated that he had had MRI's and EEG's-all were normal. Twenty one runs were conducted during Subject A's session. Subject reported that there were more than one 'individual' contacting him. Details are appended.

Subject B:

Twelve runs were conducted on Subject B. The details are appended. Subject reported that the voices tended to be external to his head, mostly above and in binaural. Subject said that on other occasions, the voices would sometimes tell him to commit suicide, or that they were his guardian angels, or that they were aliens.

Subject C:

Subject C reported that the voices are sometimes in the air and could be heard by others. She said that this was confirmed by the fact that people would respond to them, although sometimes people would think that she had uttered the words and would respond to her.

One difficulty in recording this subject was that she had difficulty breathing and the BM picked up the sounds which tended to mask any subtle sounds that might have been present. The 11 runs conducted with Subject C are appended in detail.

Subject D:

This subject reported that the voices communicated to her mostly in whispers at the beginning of the runs (but the voices got louder later on), and that occasionally they emit sounds rather than words. The details of the 8 runs conducted with this subject are appended.

Subject E:

In addition to hearing voices, Subject E also reported seeing 3D holographic images. He viewed the contacts as a mixture of "pain and pleasure." The 9 runs conducted on Subject E are detailed in the Appendix.


Subject A:

Runs were of varying length, but seldom ran more than one minute. The report from the subject about what the voices were telling him is in quotation marks. Word-like sounds appeared on the DAT, unless otherwise noted.

Run 1: "Don't say anything to [deleted]".

Run 2: "Ok, now we will talk about Carol Sterling's murder."

Run 3: "We'll talk about racism in the program."

Run 4: "fuck you."

Run 5: The BM was turned off, and both lapel microphones only, were used (in the earphones). "Why aren't you taping this, stupid ass?" (There was no audible sound on the DAT).

Run 6: Set-up the same as 5. "Ok, let's talk about the murder we committed." (Nothing on the DAT).

Run 7: Set-up the same as 5 and 6. "Fuck you, fuck you, it's not working now."

Run 8: BM only, no ear microphones enabled. "Fred Sicher is an idiot and he is stupid."

Run 9: BM only. "This is for freedom, this is for U.S. National security."

Run 10: BM + one ear microphone. "Ah hah!, some of these people suck. We are from Maryland." (there was no throat sound in the room; however, sounds appeared on the DAT).

Run 11: BM + one ear microphone. "Fred, you're an idiot."

Run 12: BM only, in binaural mode. "Turn the microphone off, it's not working."

Run 13: BM only, in binaural mode, and phase reversed on the preamp. Nothing.

Run 14: BM pointed away from subject. Nothing.

Run 15: Recorded with subject out of the room. Nothing.

Run 16: BM pointed toward the ceiling. Nothing. Subject in room.

Run 17: BM about one inch from subject's right ear. Nothing.

Run 18: BM about one inch from subject's left ear. "Aren't you?" This recorded on the DAT as a sound that could be interpreted as 'aren't you'.

Run 19: BM about 4 inches from the back of subject's head. "This is the U.S. DOD, we get orders from the Pentagon." Faint words appeared on the DAT.

Run 20: BM pointed toward the window. Subject dormant. Nothing but ambient sounds on the DAT.

Run 21: BM + ear microphone. BM about one foot from subject's head. Nothing.

Subject B:

Run 1: (we told the subject this was a sound check; however, we were in a record mode, hoping to 'trick' the voices into being louder). BM + one ear microphone. Nothing.

Run 2: "They are torturing him." Nothing on the DAT.

Run 3: ear microphone + BM. Nothing

Run 4: This run and runs 4 through 6 were conducted in an interior quiet room, but not sound-proofed. The BM, in binaural mode, was placed near the back of subject's head. There was no ambient noise on the DAT. Very faint sounds, like almost inaudible whispers seemed to be on the DAT.

Run 5: Right ear microphone only. Nothing.

Run 6: BM only in binaural mode. Nothing significant.

Run 7: BM + one ear microphone. Subject reported tinnitus. Maybe some sound on the DAT, but extremely low level.

Run 8: Right ear microphone only. Subject still reporting tinnitus. Nothing on the DAT.

Run 9: BM with phase reversed on the pre-amp. This run lasted about two minutes. Nothing.

Run 10: BM, same as 8. This run lasted about 3 minutes. Nothing.

Run 11: BM in binaural mode. Subject and researchers engaged in chit-chat and suddenly turned on the recorder and let it run about 4 minutes. Nothing on the DAT.

Run 12: BM in binaural mode. Subject and researchers engaged in chit-chat and at some point the recorder was turned on for about 3 minutes. Nothing unusual on the DAT.

Subject C:

This subject had difficulty breathing, making recording difficult. However, she wore hearing aids in both ears, affording us the opportunity to record with and without them in place.

Run 1: this was to check the sound level with the hearing aids in place. The subject's heavy breathing was the only evident sound on the DAT. The BM + ear microphone was used.

Run 2: ear microphone only, with hearing aids in place. Nothing apparent on the DAT.

Run 3: ear microphone only, without hearing aids in place. Something like a whisper was recorded on the DAT.

Run 4: ear microphone only, without hearing aids in place. Very faint sounds on the DAT.

Run 5: ear microphone only, without hearing aids in place. Some dolphin-like sounds (squeaks, whistles) were on the DAT. It was not known if these were wheezes from the subject or not.

Run 6: BM + ear microphone. Without hearing aids. A very strange sound appeared on the DAT, but its source and content was unknown.

Run 7: BM + ear microphone. Without hearing aids. A tinnitus-like tone appeared on the DAT.

Run 8: set up like 7. Without hearing aids. Nothing

Run 9: BM + ear microphone with phase reversed on the pre-amp. With hearing aids in place. Nothing.

Run 10: BM only. Without hearing aids. Nothing.

Run 11: BM only. Without hearing aids. Phase reversed. Nothing.

Subject D:

Subject reported that her voices communicated in whispers, but that the words were clear to her. This was unusual, because they normally are loud. What subject reports she heard is in quotations.

Run 1: ear microphone + BM. A 'chirp' appeared on the DAT that was not heard in the room.

Run 2: BM + earphone, with low pass filter enabled on pre-amp (rolloff beginning at 24 Hz), because an unusual amount of low frequency building noise was being recorded. "How come it's hard to hear?" Nothing was apparent on the DAT, perhaps due to the large amount of rumble that the filter failed to reduce.

Run 3: ear microphone only. Nothing. This run and all remaining runs were conducted in the quiet space.

Run 4: BM only. Nothing.

Run 5: BM only. "They aren't doing it the same way."

Run 6: BM + ear microphone. BM aimed at back of subject's head. Something was recorded on the DAT that sounded like a faint radio in the background.

Run 7: Same set up as 6. Nothing.

Run 8: ear microphones only. Nothing except a chirp that sounded like 'tsk'. Subject said she recognized the sound and would like it enhanced and a tape given to her of the sound. Researcher agreed.

Subject E:

The first 4 runs were made in the quiet room. The balance were made in the original space where most of the recordings took place. Voices reported by the subject are in quotations.

Run 1: ear microphones only. Phase reversed. "Do you want to go home?" Nothing audible appeared on the DAT.

Run 2: ear microphones only. Subject reported that when he reads, the voices are usually louder. Subject read text during the run. "Why don't we stop.....?" Nothing definitive on the DAT.

Run 3: ear microphone + BM. Nothing.

Run 4: same set up as 3, but with BM aimed at the back of subject's head. Subject reported hearing something, but could not make it out. Nothing on the DAT.

Run 5: BM + ear microphone. Subject turned a magnetic field counteractor on. There was lots of ambient noise during this run. Near the end, a strange sound appeared on the DAT that was not apparent in the room during the run.

Run 6: BM only. Counteractor on. A voice appeared on the DAT that was not audible in the room; however, it was very faint and could not be interpreted.

Run 7: BM only, with counteractor off. Significant noise from another room overwhelmed the subtle information that may have been present during this run.

Run 8: BM only, with counteractor off. Nothing.

Run 9: BM + ear microphone. Low frequency hum that had been present for most of the runs was gone. "I don't care." Anything on the DAT was at such a low level as to be inconclusive.


The hope was that in one day and with five subjects who hear voices in their heads, we would get a similar recording to one whose voices are clear enough to make out. However, that recording took several months to obtain.

This experiment, although unsuccessful in obtaining a similar recording, did accomplish several things, including the exercise of the equipment in additional modes, the use of multiple subjects with various presentations of harassment, and data that is not conclusive (concerning the testing of the hypothesis) but that is valuable. The collected data has anomalous content; but not enough to warrant firm evidence that a technology was being used. The scope of this experiment was limited by funds and other considerations; however, it will be used as a basis for further work (see Recommendations). Further enhancement of the recordings may yield meaningful results; however, this has not been accomplished.

Although the data obtained by this experiment does not conclusively prove the hypothesis, it does not rule out a technical basis for the claim that the subjects are being subjected to some sort of mind control technology. We were faced with the dilemma of having heard anomalous sounds in the room that did not appear on the tape with sufficient intensity for us to definitely identify them as voices, even though the subjects could understand what the voices were saying. All we could do was use a graphic equalizer to decrease the amount of repetitive ambient background noise (fans, etc.) and amplifiy the results. We did not have access to expensive racks of equipment as used by the FBI and other government agencies that can pick a faint signal out of noise and make sense of it.


Based on the results obtained in this experiment, further research and testing is warranted.

Variations on this experiment (such as including equipment to monitor high frequency and extremely low frequency carrier signals) can be thought of by anyone reading this. Data has been sent for comment to an MD at the Detroit Imaging Institute. An improved version of this experiment, including direct skull recordings, will be proposed as a CAHRA Proposal, in process. It will include the further enhancement of the existing data in an attempt to provide a basis for further recording.


For those wishing to replicate the experiment, the lapel microphones can be purchased for about $20 each at Radio Shack, and any high quality set of headphones can be used PROVIDED they completely cover the entire ear with a rubber ring (in order to seal out extraneous ambient noise and seal in anything the ear microphones may be picking up from the subject's ears).

The pre-amp cost about $250; however, good quality preamps can be obtained for about $100 designed for use in high-powered car stereos. This may be unhandy, because they are mostly powered by the car battery. Any high-gain, low distortion pre-amp can be used, and should cost around $125 for 115v wall current power and no frills.

All DAT recorders are expensive, and can be found many places from vendors on the Internet. Perhaps Circuit City carries them, also. The one used in this experiment cost $2500; however, a decent one (maybe used) may cost $1000 or less. For someone familiar with computers, it should be possible to (with the appropriate software) use it to make digital recordings directly on CD ROMs. Otherwise, even a good analog recorder could be used to gather data. The beauty of a DAT recorder is the complete absence of noise. This enables the recording to be amplified after it is made without increasing analog tape hiss.

The Blue Mouse costs about $2000; however, a reasonably good, but much less sensitive directional microphone can be obtained for about $100 and up.

The frame work to hold the Blue Mouse was hand made and not difficult to do; however, the exact placement of the reflector is critical and should be done by professionals. Cost: about $50 for the dish, and $50 for set up. A few dollars for the materials to make a stand. See photograph for details.

The total cost to assemble a less sensitive set of recording equipment, but one that may be suitable for capturing sounds would be about $475 plus a DAT recorder (which probably could be rented for about $25/day or less). A good quality analog recorder and a multi-band equalizer could be used instead of the DAT recorder; however, the quality of the recordings will be diminished.
