Atkinson, Comm-Eng Date: Wed Feb 2, 2000 5:23pm Subject: DTV Signals Mask Radiated Emissions DTV Signals Mask Radiated Emissions Digital TV broadcast signals add yet another ambient signal to the mix. [original author unknown] If you live in a major metropolitan area, then your local TV stations have already begun broadcasting in digital format. As of November, 100 DTV stations were on the air, and by 2006, all TV broadcasts in the US will be digital. While viewers may enjoy the digital television picture, EMI test engineers find DTV to be just one more aggravation that impedes their work. Both the VHF and UHF bands are within the range of microprocessor clocks, so EMI test engineers already account for local analog TV signals when they are performing radiated emissions testing in an open-area test site (OATS). The DTV broadcasts, which currently operate in the 470 MHz to 806 MHz UHF band, add yet another set of ambient signals to the electromagnetic spectrum. What makes DTV broadcast signals different from conventional TV? Plenty. Although both occupy a 6-MHz bandwidth, the analog TV signal has three distinct narrowband peaks-video subcarrier, color subcarrier, and audio subcarrier (from left to right). In contrast, the DTV spectrum is flat across the entire channel's bandwidth, so it masks more radiated EMI than do the narrow peaks of analog signals. So what can you do about radiated EMI measurements in the presence of ambient DTV broadcast signals? The obvious way around OATS testing in the presence of DTV signals is to leave the OATS-perform your testing in a semianechoic chamber. Unfortunately, few test labs have chambers large enough to perform EMI measurements at 10 m. For OATS measurements, you have a few options. First, you should find out if you have any DTV broadcasters in your area. In the US, you can check the Web sites of the FCC (www.fcc.gov/mmb/vsd/ files/dtvonair.html) or the National Association of Broadcasters (www.nab.org/ PressRel/Dtvstations.asp). I suggest you also check the local DTV broadcaster's Web site to see which programs are broadcast in DTV format and plan your tests around those programs. (Right now, many stations are broadcasting in digital format during evening prime time hours only, but that will gradually change as stations add more programs to their DTV schedules.) You can also check the FCC Web site (www.fcc.gov/oet/dtv/tvchfreq.html) for channel frequency allocations. For precompliance tests, you can detect EMI by narrowing the resolution bandwidth of your spectrum analyzer or EMI receiver to, say, 1 kHz. The narrow bandwidth will effectively reduce the wideband DTV signal within that bandwidth. You can't narrow the bandwidth for actual compliance tests, because FCC Part 151 and CISPR 22:19972 require you to set the resolution bandwidth of your receiver to 120 kHz, says Roland Gubisch, chief engineer for EMC and telecom at Intertek Testing Services (Boxborough, MA). Yet, by reducing the resolution bandwidth for precompliance testing, you can determine whether your product is likely to pass compliance tests. You can also try reducing the distance between your EUT and receiving antenna to boost EUT signals relative to the DTV background. Standards require testing at 3 m or 10 m for compliance tests, but you can-in limited cases-reduce the distance to 1 m or 2 m for precompliance testing of 3-m measurements. A scale factor of 1/d relates emission limits and distance, but you can't apply it at low frequencies (those less than 30 MHz) or for large EUTs (see FCC Part 15 section 15.31(f) for details). The same scale factor applies to CISPR 22 measurements referenced to 10 m, but you can use the scale factor for Class B equipment only (see clause 10.2.1 of CISPR 22:1997). If you do not have access to a semianechoic chamber and if the scaling of distance and bandwidth still does not yield the information you need, you do have another alternative: noise cancellation. This alternative requires two antennas, one near the EUT and another at a greater distance. The near-EUT antenna receives emissions at amplitudes high enough to detect them over the ambient signals. Then, you can measure the power of the emissions at the second antenna's distance and use the result to perform a calculation to cancel the ambient signals. FOOTNOTES 1.

Atkinson, Comm-Eng Date: Thu Feb 3, 2000 10:25pm Subject: The Transistor The Transistor The transistor was invented on Christmas Day, 1948, by Emily Gerund, a high school teacher of English from Boston, Massachusetts, who was serving a 20 years-to-life sentence in the state penitentiary for throwing her husband's coat under a speeding truck. The judge was rather severe with her because her husband was still in the coat at the time. The Governor of the state owned an electronics firm and so was able to provide surplus vacuum tubes to the prisoners so that they could decorate their Christmas trees. Now Emily had an extremely tiny tree, much too small for a string of SV6s or even for a single QL4. But she just happened to find some germanium crystals lying around. She stuck three wires in each one and used them to decorate her tree. She was quite surprised when after she completed the tree, it started picking up the Jack Benny Show. The Governor, upon learning about this and realizing its implications, immediately rushed to the prison and offered the English teacher a full pardon in exchange for the manufacturing rights to her invention. "Of course, Governor," she replied. ... "In this case, I'll be glad to let you end a sentence with a proposition." -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

One day, a Navajo elder and his son were herding sheep and came across the space crew. The old man, who spoke only Navajo, asked a question which his son translated. "What are these guys in the big suits doing?" A member of the crew said they were hired by the government as astronauts, practicing for their trip to the moon. The old man got all excited and asked if he could send a message to the moon with the astronauts. Recognizing a promotional opportunity for the spin-doctors, the NASA folks found a tape recorder. After the old man recorded his message, they asked the son to translate it. He refused. So the NASA reps brought the tape to the reservation where the rest of the tribe listened and laughed but they also refused to translate the elder's message to the moon. Finally, the NASA crew called in an official government Navajo translator from the CIA. He reported that the moon message said, "Watch out for these guys; they have come to steal your land." -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

These are the latest models and were used for sales demos only. They are essentially new and carry the full original manufacturer's warranty. These are designed for many security uses and are a primary tool for serious TSCM'ers, especially those who use NLJDs. You can X ray telephone handsets, desk and office artifacts, and similar. You also can X ray your own or someone else's limbs. Although not sold or suggested for that purpose, an X ray machine is the ultimate sweep gadget for impressing customers. Everyone has an OSCOR now. How many have an X ray? How do you inspect 40 telephone handsets on a large sweep? With the X ray, you can do them in fifteen seconds each, and nothing will hide. How else can you do them? See inside lamps, office equipment and other items capable of concealing electronic eavesdropping devices. Viewing area is 50mm (2 inches). Will accept objects to 175mm in size (just under seven inches). Weighs 6.6 pounds. Ships in padded aluminum briefcase. X ray intensity within BRH guidelines, but be responsible. These are the high resolution, high intensity models, in current manufacture. Power is internal rechargeable battery (new battery included) for 20 minutes on time, or external12 VDC or external 110/220 VAC for continuous operation anywhere in the world. Unit is suitable for lab or field use. Secondary applications are veterinary, sports (X ray suspected bone fractures right on the ballfield), EMT/ambulance, EOD to inspect suspect letters/parcels for explosives, narcotics/contraband, materials inspection/failure analysis, even X raying children's candy at Halloween. The factory new price is $7950, and they sell to qualified users only. My price is $5250 each, which is well below any price anyone will pay elsewhere. Best trade price is $6750. Stocking dealer is $6000. Two units available. Can take credit cards for payment. Units are at factory now for inspection and will be ready to ship next week. Warranty starts on receipt of unit. Remember, these are basically new units, not tired old used, "refurbished" or "overhauled" pieces with low resolution, low brightness and low penetration. The last time these were offered they sold in one day, and they were refurbished units. Holler if interested.

Both are the source of ionizing radiation that can have serious health side effects. The statement, "You also can X ray your own or someone else's limbs," is unprofessional and suggests that the writer has little familiarity with radiation safety. No one should routinely use a portable fluoroscope without first being put on a radiation health safety program that systematically monitors one's blood for the telltale signs of excessive gamma radiation exposure. Neither should anyone purchase a portable fluoroscope without understanding that good practice will require that it be examined at least annually by a qualified safety examiner. Because of the handling that portable equipment gets, the otherwise sealed seams will sometimes open up and expose the user to radiation. I am unfamiliar with the equipment mentioned in this message, however the implication is that the user may be looking back through leaded glass at the radiation source. There are other units on the market that do not require the user to stand in the path of the radiation source. They are safer choices. Image interpretation training is a close second behind radiation health safety in choosing to use a portable fluoroscope. A portable fluoroscope is a good diagnostic tool, however as anyone who has ever had a briefcase of electronic equipment pass through an airport fluoroscope without being thoroughly physically inspected can attest, the absence of recurring training makes them a much less effective tool. They are not magic wands. They cannot find bombs and they cannot find "bugs." They can only highlight objects which, to the well-trained observer, indicate that further close physical or instrumental examination is necessary. Before buying this or any other used fluoroscopic equipment, insist that it first be examined by a qualified inspector who will not only provide a written inspection report that certifies compliance with federal health standards, but he/she will also help guide you to a radiation safety program. 8 From: James M.

Simply cross out the names and addresses of people you don't know. Fool other drivers into thinking you have an expensive car phone by holding an old TV or video remote control up to your ear and occasionally swerving across the road and jumping the curb. Lose weight quickly by eating raw pork and rancid tuna. I found that this enabled me to lose 12 pounds in only 2 days. Avoid parking tickets by leaving your windscreen wipers turned to fast wipe whenever you leave your car parked illegally. No time for a bath? Wrap yourself in masking tape and remove the dirt by simply peeling it off. Apply red nail polish to your nails before clipping them. The red nails will be much easier to spot on your bathroom carpet. (Unless you have a red carpet, in which case a contrasting polish should be selected.) If a person is choking on an ice cube, don't panic. Simply pour a jug of boiling water down their throat and presto! The blockage is almost instantly removed. Save on booze by drinking cold tea instead of whiskey. The following morning you can create the effects of hangover by drinking a thimble full of dish washing liquid and banging your head repeatedly on the wall. Give a man a fish and he will eat for a day. Teach a man to fish and he will sit in a boat drinking beer all day. =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

Because low energy (typically 50 KeV) systems present less risk than the ones used to inspect more dense items they can be adequately monitored by a ring/control combination that is cycled through a radiation health firm every few months. Drawing blood is necessary in atomic bomb facilities (and when clients fail to pay). Getting a machine inspected when it is purchased is a good idea but again not that complicated. Just take it to the licensing facility for your region. You likely will have to take it to them because these machines present such a small radiation risk that they will not come to you. Measurements on our C-arm x-ray machine indicate that if we work day and night in the sweep business (hope, hope...) that we might accumulate 10% of normal background radiation by using the fluoroscope. After using one for the last 5 years I can testify that they don't promote hair growth but certainly do help with inspections.

Jay: The Teletrac unit is never programmed to "fire" at a given interval. The unit lies dormant in constant receive mode until it is queried by the system. When it receives a signal that says "where are you?" it replies with "here I am." The "preprogramming" you are referring to is actually done in the tracking computer. At preprogrammed intervals it will dial into the tracking system and query the unit to reply with it's location. Pulling the battery and reconnecting will not cause it to send a locate. Additionally, many private investigators place the units on vehicles with their own battery packs.

You see alot of books on countermeasures, and you wonder if it is worth ponying up large sums of cash for a book of questionable content. Some of Mr. Whiddens publications are a perfect example of overpriced books. In his defense though, I will say that Whidden is one of the best educational writers I have ever seen out of the thousands of books in my personal library. In his publication, "The Ear" (grossly overpriced), he has the amazing ability to take a moderately complex topic (to a laymen) and write it so that anyone can understand it. Anyway.. I'll post some of my reviews at random within the next week. ------------------------------------- A GUIDEBOOK FOR THE BEGINNING SWEEPER ------------------------------------- A Guidebook for the Beginning Sweeper is an extremely useful and insightful book written by Glenn H. Whidden and published by his company Technical Services Agency (TSA). This 219 page manual represents just one of the many fine publications authored by Whidden. Other titles include, The Axnan Attack, The Russian Evasdropping Threat, The Ear, and the TSCM Threat Book series (volume I and II). Of the many books I have read and reviewed which deal with the topic of electronic countermeasure services, I conclude this book to be the most usefull from the business standpoint. This book is low on "fluff" and high on technical content. Although, it is likely not the most interesting book you will read, it acts as indespensable reference for anyone interested in the business aspects of security. The book opens with a brief and 'to the point' chapter written for individuals who have pondered the possibilities of offering countersurveillance services. Whidden then offers a brief explanation of the many elements of an eavesdroppping defense; explaining that an effective sweeper should have a proper mindset and should follow ceartain rules of the game in order to be effective in plying ones trade. These aforementioned rules, which Whidden dubs- "The Moscow Rules", comprise an entire chapter of the book. The remainder of the book is dedicated to the business and procedural aspects of countermeasures and security. Although this book does not directly contain information on the technical details of countermeasures (ie: what equipment to use for a "sweep" and how to implement such devices), it does deal thoroughly (yet simplisticly) with the most common eavesdropping threats and outlines common vulnerabilities. Mr Whidden then proceeds to walk the reader step-by-step through the process of performing countermeasures services. Topics covered include; initial client contact, what to say and what not to say. The necessity of using photography when planning sweeps. Different methods to calculate costs for your TSCM services. What to do if you find a clandestine device (both legal and moral issues may arise). A fairly extensive glossary of terms also serves to form the basis of a well-rounded book. Perhaps the most usefull aspect of the book are the extensive (approximately 90 pages) checklists, and sample reports which the security technician can utilize to fulfill his duties of properly informing the client of the thoroughness of the search. The sample reports alone are worth the price of the book. I conclude this review by saying that this is a "must read" book that should be on the reference shelf of anyone who is interested in the field of security. This book is not just for countermeasure technicians but rather is equally usefull for anyone in an administrative capacity.

Telephone Eavesdropping and Detection is the premiere reference manual on the subject of telephone wiretap detection. There simply has never been a more comprehensive and well written book written on the subject. It is published by Taylor Hill, and written by Richard J. Udovich and Charles L. Taylor who are men of well respected credentials. The textbook was published in 1990, so most of the information is current and applicable. The opening credits give the reader an indication of just how well planned this books was, as it lists some of the most well known professionals in various fields ranging from telecommications experts from AT&T, and Bell Research, to well known surveillance and security industry experts. This textbook is formatted in a fairly intuitive manner designed as a teaching aid, and all topics and subtopics are clearly labled to help the student learn and take notes. Although personally, I felt that many chapters were clearly out of order; but a slight nitpick. The best way to review this book is to let the contents speak for themselves. Here is a greatly simplified sample of the topics which are dealt with in this 500+ page manual. The book has 4 main chapters divided into 25 subsections. A useful appendix and glossary is also included. In addition, an evaluation test at the end of each section serves to to verify that the reader understands the contents. -------------- Chapter 1 - Introduction to Basic Electronics Basic Physics Basic Electrical Theory Basic Circuits Electronic Components Sound and Microphones Chapter 2- The Telephone System, Basic Design and Operation Telephone Exchange and Cable Distribution System (Outside Plant) Building Telephone Cable Distribution (Customer Premise) Electro-Mechanical Key Systems Electronic Key Systems (EKSU) Private Branch Exchanges (PBX) Chapter 3- Telephone Wiretaps and Detection Telephone Taps- Operation and Electrical Characteristics Common Wiretap Methods Telephone Wiretap Detection Equipment Wiretap Detection Procedures For A Residence Wiretap Detection Procedures For Outside Plant Cables Wiretap Detection Procedures For Electro-Mechanical Key Systems Wiretap Detection Procedures For Electronic Key Systems Wiretap Detection Procedures For PABX Systems With EKSU Chapter 4- Telephone Instruments and Hookswitch Bypass The 500 Telephone Instrument- Operation, Construction, & Circuit Analysis Hookswitch Bypasses and Electro-Mechanical Telephone Instruments Electronic Telephone Systems- Hookswitch Bypass Analysis Hookswitch Bypass Detection Procedures And Equipment Appendices- Common Audio Pair Conductor Resistance in Loop Ohms Interpreting The Resistor Color Code Summary of Important Terms Line Balance Test Schematics Symbols Feeder And Distribution Service Areas Outside Plant Facilities Test Locations For A Typical Key System Test Locations For A Typical Neighborhood Manufacturers and Distributors Evaulation Test Answers (for all 25 sections) Glossary Index -------------- Telephone Eavesdropping and Detection will be particularly useful to the reader who is looking for a "hands-on" type of books. Within the textbook, there are literally hundreds of diagrams which help to illustrate the lessons in the text. In addition, the manual demonstrates pictorially where the phone taps, and the electronic test equipment (voltmeters, time domain reflectometers, line tracers, TSCM amplifiers etc..) are to be placed, as well as step-by-step instructions on how to perform various tests to detect the myriad of wiretapping threats. I was somewhat dissapointed that the book did not delve more deeply into explaining the intracacies of the telephone system; particularly with respect the the complexities of PBX and electronic telephone systems which are found in most office buildings. However, as the author stated at the beginning of the book, that simply would not be possible, because it's just too much data for one book. So if you want to sink your money into this book, might I also suggest you purchase a few supplemental books on telephone systems (ABC Teletraining has the absolute best series of telephone training books published), or you might want to get some books on basic electronics as well (depending wherein your knowledge is lacking). In closing, I feel the need to mention the price of this book. Indeed it is excessively expensive, as are many books of an esoteric nature which were written specifically for professionals. However, if you are either a professional in the field of surveillance countermeasures, telephone security, or a corporate information security and intellectual property rights practitioner, or even a curious and dedicated hobbyist, this book is worth every penny. There are literally hundreds of books written on countermeasures, as well as several books specifically dealing with wiretap detection. Why buy all those other books, when you can simply purchase this one book which has what all the other books have combined (almost, anyway)? Taylor Hill Publishing P.O.

Murray Date: Fri Feb 18, 2000 5:24pm Subject: Re: Book Review - Glenn Whidden As a regular reader of the list, and a full-time practitioner in this field, I would like to comment on the book reviews posted today. First... Anyone who has written a book review appreciates the time and effort it takes to do it. To whoever posted these unsigned pieces, your efforts are acknowledged. The following is not meant to discourage you. They reflect what I would like to see in future pieces, and some critical personal opinion... ď Consider attaching the customary "about the author" paragraph to your future book reviews. Without this, readers do not know how much credibility to give to your writings. (For all anyone knows, a writer's expertise could be in a totally unrelated field, like running.) ď On your comment... "You see alot of books on countermeasures, and you wonder if it is worth ponying up large sums of cash for a book of questionable content. Some of Mr. Whiddens publications are a perfect example of overpriced books. In his defense though... " Mr. Whidden does not need you (or any of us) to defend him. He is probably the best known, and most respected expert in our field. His credo could be "If anyone speaks ill of you, let your life be such that no one will believe him." In his case, it works. (Just an aside... You should be aware that people who know him would be pleased to wear your anal sphincter for a pinkie ring over those comments.) I have purchased, read (and re-read) _all_ of his books and publications. I can say - without reservation - all of them are well worth every penny spent, several times over. Glenn Whidden has a lifetime of experience and knowledge which he is sharing at nominal cost. Let's put this into perspective. Total the cost of all his writings. Could you hire an ex-CIA technical specialist (with patents to his credit) to consult with you for two hours? Not at that price. Even if you paid more... Could you ask all the right questions, invent a business model, and take notes fast enough to walk away with the knowledge in his written works? Of course not. ď Please spell check before you post your book reviews. ď May I suggest you review some other publications to add balance, perspective and depth to your review of The Guidebook for the Beginning Sweeper. How about doing a side by side comparison with... A Countermeasures Cookbook on Conducting Professional TSCM Services: The Ultimate Guide to Testing and Checking for Bugs and Illegal Wiretaps, by Ralph Thomas? (For list readers who can't wait... an excellent review of this book appears in the January issue of Security Management magazine (page 140). (Note: It is the review that I am calling excellent, not the book being reviewed.)) ď When commenting on book costs, why not show a comparison to... something. Peruse the catalogues of the major security / technical / legal book publishers for guidance. (Butterworth, Clark Boardman, West, CRC, Elsevier, Wiley, Prentice Hall, Addison Wesley Longman, McGraw-Hill, etc.) This will give your readers a concrete basis for comparison. It may also inspire you reevaluate the sophomoric comment, "Some of Mr. Whiddens publications are a perfect example of overpriced books." Thank you for considering these requests, and my personal opinions. Kevin Kevin D.

Thanks for reading. I'd like to build a small breakout box with several rotary switches which would allow me to to the following: *Quickly plug into a standard 4, or 6 conductor wall jack, or 8-conductor wall jack. *Select any wire combinations for TDR, DVM, receiver-analyzer or audio amp. *Switch or reverse combinations for balance, resistance and capacitance tests. I don't want to shell out a zillion dollars- Can someone give me a table of pinouts for female RJ 8-conductor connectors as they correspond to the wiring color code? I may want this black box to have through connections, and it must handle connection to 4, 6 and 8-wire phones. Has anyone already built one of these who would care to discuss or share a schematic? (Please excuse the missing or wrong date on my email... it is a Micro$oft problem and will be resolved when I get a real computer and a real browser) Jay Coote, W6CJ Licensed Private Investigator -TSCM specialist Los Angeles 20 From: Charles Patterson Date: Wed Feb 16, 2000 9:20pm Subject: Re: 4, 6, 8-conductor phone breakout box ? Hi Jay, I just returned from ye ol' Radio Shack with a new box to transfer my breakout box into. (My old box was built in a hurry, and it shows a bit too much wear). There are many different wiring schemes, particularly for the 8 conductor jacks but you shouldn't have to worry about that too much since you will need to check all pairs anyway. The middle two conductors are almost always the main pair, at least in a single line phone, the next outer pair could be a second line. In the case of an electronic pbx or key system, the middle pair often carries the analog audio and the outer pair carries the power and signaling. If it is a fully digital system, only one pair is needed for everything. Some use the middle pair (Toshiba, Panasonic DBS) while some use the second pair (Panasonic KXTD) and can still use the middle pair for an analog signal. The third pair (spreading out from the middle) was often used in some system to allow for "off hook call anounce". This was to allow paging through the speaker of a phone while the phone is still in use. Some phones will have that third pair wired right to the speaker in the phone set, perfect to use for listening in. To see the usually coloring try: http://www.ablecomm.com/learnpg.htm When wiring a jack the middle pair is usually numbered 4 and 5, second pair is 6,3. It would be good to at least note these positions as starting points on the rotary switches. In my new box I will have two banana type binding posts wired to the center contact of the rotary switches (one to each switch). I will also wire a mini jack in parallel with the banana posts for easy connection to my amplifier. Then take eight positions of each switch and wire each of them in parallel to the eight positions of an 8c jack. Now you will have each switch able to connect one output banana post to every contact of the jack. Note that this way there will also be a short across the output posts if the two switches are set at the same setting- don't let it fool you if you're spinning the knobs doing a resistance check. On the jack side, I plan to have two 8c jacks wired in parallel and keep a mod jumper cable handy. this way I can use it as a feed through and run the phone set live while testing. I may add a handset size jack just for convenience. 4 conductor line plugs will usually fit fine in an 8c jacks but handset plugs tend to wobble too much. You can use two R/S 275-1385 rotary switches to give you twelve switching positions, you only need 8 positions, I'm still trying to figure out something fun to do with the other 4 positions (my balanced line tester is in a separate box, it was a bit more complicated). I hope this makes sense charles Charles Patterson communications@c...

Charles, Thanks for the information. I began on this box about 1 year ago and had a lot of projects in the meantime- a 911 commcenter for my "other" fulltime job, and so on. Now there's more time to organize my TSCM tools. Good! I was concerned about the use of female 8C jacks on my box; more accurately that something may get reversed or fouled up in the through connection, should I connect some types of phones through the box while testing. I'll just have to watch those shorts so I won't have to leave the job site at 01:30 in the attempt to buy a fuse for the phone system ;-) I hope I may pick your brain on this box project and on what you did to speed up balance tests with your box..... One TSCM book suggested a pair of matched 2700 ohm resistors for the balance test.

Though this is not strictly related to TSCM but for a client residence, I thought I would ask any sound experts on the list. The problem is I want to deaden sounds, entering the building from outside (in the 300-5000 Hz range). The structure is older, single-story, stucco over woodframe with drywall inside. There is no heat or sound insulation inside the walls, just air space between the outer stucco and inner drywall. Are there safe (no chemical outgassing) expanding foam substances which can be injected between the walls? Other suggestions? Thanks (Please excuse the missing or wrong date on my email... it is a Micro$oft problem and will be resolved when I get a real computer and a real browser) Jay Coote, W6CJ Licensed Private Investigator -TSCM specialist Los Angeles 27 From: James M.

About the only things you can do is to build "acoustical mass" and "acoustic isolation" as part of a retrofit.

I don't have the exact answer, but a source to contact. Airports around the nation are modifying homes in areas where airports are expanding. One of the techniques used to keep local residents content, if not happy, is sound abatement. Contact your local airport public relations man and they can point you in the right direction, sure I am. I know that Logan in Boston and Manchester in Manchester, NH have been doing this sort of work for years.

I believe I used the 2700 ohm resistors too If you have two jacks wired really in parallel, then it can work as a feed through without any worries. That shorting thing is not a problem for the phones, the two terminals will not be shorting out the jack. Its just that if you set both switches to the same pin, it will look like a short to a dmm, you will actually be reading only one conductor, and might fool your readings. My new box is turning out pretty good (if I dare say so myself!)! good luck Charles ----- Original Message ----- From: Jay Coote To: Sent: Thursday, February 17, 2000 9:25 AM Subject: Re: [TSCM-L] 4, 6, 8-conductor phone breakout box ? > > From: "Jay Coote" > > Charles, > > Thanks for the information. > I began on this box about 1 year ago and had a lot of projects in the meantime- a 911 commcenter for my "other" fulltime job, and so on.

I was concerned about the use of female 8C jacks on my box; more accurately that something may get reversed or fouled up in the through connection, should I connect some types of phones through the box while testing.
