Jay, I have been using several telephone analyzers for years including several Winklemann units, a BTA-3, BTA-2, ETA-1, ETA-2, ETA-3, MCS-77, AT&T Loop Analyzer, Several Kaiser units, a Soviet Unit, and others. I would classify telephone analyzers into four separate group, each with its own function: The first is a box designed to check the telephone instrument itself for failure or modification (up to 8 wires at a time, plus earth group). It is actually quite easy to check a given model of phone when such a system is used. Of course you still need to do a physical inspection, along with an optional X-ray. This will commonly have multi-tone generation, "listen in", carrier detection, and so on. The second box is similar to the first but is designed to test "The Loop" or the wiring (such a system ALWAYS includes a TDR), and only a single set of wires are tested at a time (but it may have a multiplexed box, as mentioned below). The most critical of these tests in the TDR mapping, leakage tests, and the voltage tests. The third type of box is one used to test the older 25 pair telephone systems. These systems often contain a "high voltage option" that must be used with caution (keep these monsters away from any modern PBX systems). The fourth is a "Multiplexed Box" that expands any of the above instruments into "thousands of combinations". This is usually done though the use of a bank of CPU controlled reed relays, or (God forbid) manual switches. In answer to you question... YES tonal sweeps (at least 4 tones) is important, so is leakage test, voltage tests, RF tests, and TDR. Stay away from the high voltage tests, and instead use a "Kicker", but only on a limited basis. IMHO, The best all around hands down Telephone Analyzer I have found is the Kaiser 1080H (I sell them for only $2970, which is a tenth to half the price of other units we offer). I would suggest supplementing it with an 2030 for the RF checks (which I have hard wired into mine). The built in TDR is also great (I modified mine to add a ten turn heli-pot for the timing). The battery and compact size makes it great when working in the phone rooms. I also hacked in a pair of mini-WECO jacks so I can use popper clips with greater ease. I also added a small transient limiting circuit which lets my spectrum analyzer couple directly to the line under test. I should add that virtually every instrument I own has been seriously modified (sorry but I'm a geek).Also, the 1080H "kicks-ass" when you add one of the new Fluke 199 oscilloscopes. After almost two decades of "Telephone Analyzer Grief" I ended up sitting down last Fall, designed and then built my own Telephone Analyzer. If anybody out there is interested in my design, give me a call... right now it is purely an analog prototype, but computer control via USB is in the works (as I have spare time). If you can get an ETA-1, or ETA-3 for under $1000 snap it up... other wise spend your money on a Winklemann 200, or a Kaiser 1080H. -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

The computer was left by an MI6 officer - thought to be a female trainee - who had spent the evening drinking with colleagues in a tapas bar about a mile from the MI6 building at Vauxhall Cross in central London. It was lost on March 3, one day before another laptop containing secret information was stolen from an MI5 officer at Paddington station. MI5 said that although information on its stolen computer concerned Northern Ireland, there was no threat to national security and no lives were at risk. In addition, the computer's classified data was encrypted and could not have been read without a separate electronic keying device. MI6 is responsible for foreign intelligence and MI5 handles internal security. By contrast, the "training material" on the MI6 computer was not encrypted, and worried intelligence officers were forced to ask police who recovered it 13 days later if anyone had read it. So frantic were they to recover the computer that they placed an advertisement in the classified columns of the London Evening Standard purporting to be from an "academic" and offering a "substantial reward". The advertisement claimed that the Toshiba 4000 series CDS, a top of the range laptop, contained vital research notes for his PhD. Its loss was important enough for Robin Cook, Foreign Secretary, to be informed, but the Metropolitan Police recovered the laptop two weeks later. An inquiry is under way into the incident and reports will go to Mr Cook and the intelligence and security committee, the parliamentary watchdog which oversees the activities of MI5, MI6 and GCHQ. A Foreign Office spokesman said: "We were assured by the police that the laptop was not compromised. It largely held training information. It was not something hugely damaging." But there is no doubt that the loss of the computer is very embarrassing to MI6, which makes a great play of the fact that it never reveals details of its operations. It has even refused to release its historical archives from the First World War, arguing that to do so risks putting off potential agents who would not want to know that at some point their names would be revealed. Marco Rebato, owner of Rebato's, the tapas bar where MI6 staff apparently congregate, said he had no recollection of a drunken spy. He said: "No MI6 agents or anybody else came back to my bar to say they had lost their laptop or left it behind. If someone that drunk had been in, we would have remembered straightaway. It's not like we would know there are secret agents coming here." But Frank Henry, owner of nearby South Lambeth Cars, said he had been visited by two men who asked if a laptop had been left in one of his cars. He said: "It was all a bit odd. I got a visit from two smartly dressed men who said they had lost a briefcase with something important in it which they thought they might have left in a taxi. "I remember them saying that they had been to a tapas bar just down the road and that they had been the worse for wear that night. One said they couldn't remember which cab firm they called because they were in such a state and they were trying all of them in the area. "They seemed a bit cagey, as if they were trying to bluff me or play a game, like they didn't want to tell me everything although I suppose they were quite friendly. We had no record of being called out when they said." Sir Tom King, chairman of the parliamentary watchdog, said insufficient thought had been given to the impact of new technology. He said: "It goes right to the heart of intelligence and security. They depend on people, often very brave people, being willing to give them information. People risk their lives in giving the information in the confidence that those agencies will keep it protected." *-------------------------------------------------* "Communications without intelligence is noise; Intelligence without communications is irrelevant."

The final version of it has now been pasted into an active page on my website. If anyone is interest in the final product you can find it at the following link. http://www.tscm.com/howcost.html It is a shortened version of the one I myself use for estimating projects, but I've arranged it so that non technical people should be able to understand it, and work out an estimated project cost (this one is 3-4 pages long). The full 50+ page estimate worksheet I use can accurately estimate (or model) a sweep to within +/-15 minutes on a 4 day sweep. I had considered break out the construction elements a bit more, and listing the costs of the physical inspection (ie: NLJD, Xray, Thermal), but I am still undecided. I am a bit undecided on how far I want to break down the computer and videophone based inspections (as they can take a great deal of time, and should be handled as a project within itself). Same with ISDN, T-Carrier, and related evaluations. The other issue, is breaking down the external RF surveys... I generally like to run at least three external RF sweeps outside of the building, and then at least two internally sweeps before I check the sound stage. The problem is how do I break this down so that the customer finds the RF segment easy to understand, and is comfortable with someone spending 6+ hours on it? I also have considered adding "times" to the worksheet so that customers can see that it takes 10-15 minutes for this, 30 minutes for that and so on. Of course you can take the total balance, and simple divide my daily rate. Your feedback will be greatly appreciated (as always) -jma PS: Ahem... on an added note... several list members (who will remain nameless) have already ripped off my estimate worksheet and plastered it up on their website... please ask first, give me credit, and at least buy me dinner (flower are optional). =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

The VBA is an excellent little antenna which gives the 2.4 GHz ISM band a little bit of a boost, and makes it a lot easier to find various microwave threats including video devices. Technically it is a "Threat Specific Antenna" in that it is high gain, and focused (or concentrated) on a fairly narrow chunk of the RF spectrum. The VBA combines a small log periodic antenna (which is highly directional) along with a preamplifier. If you have an OSCOR, or an AVCOM spectrum analyzer you will want one of these antennae. By the way... I sell them for $495, so let me know if I can help you out. -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

I'd like to hear about good mobile antennas for RF monitoring from outside the sound stage. For scanner listening and VHF low/high and UHF monitoring, I have used Radiall-Larsen NMO dual-band antennas. These are designed for VHF 150-something and UHF 460-something and have some lowband performance although I have not swept one. Plus- it looks like a plain comms antenna on the van. I have seen other "patch" "dome" and "blade" stealth antennas, some stick in vehicle windows like a decal, others are not as obtrusive as a whip antenna. Some of the companies who produce L/E surveillance vans make good use of ladder racks and other equipment which would look normal on a service truck or van to disguise their VHF/UHF/MW antennas... For VLF-HF, I suppose one could use a standard 1-meter whip and an "active whip" preamplifier (with VLF upconvertor if the TSCM receiver is "numb" on VLF). Smaller yagis or microwave LP and horn antennas could simply go behind the vehicle's windows, aimed towards the site. Ideas? Jay Coote Los Angeles 133 From: James M.

Also since we are hunting for extremely low powered signals I would encourage you to stay away from NMO mounts or any other type of "mechanical/electrical connection" between the antenna and cable. I have had really good luck with some of the Radio Shack magnetic mount scanner antenna's as the new one have a BNC connector instead of the old Motorola jack. I add a small pre-amp into the base, and supply DC voltage over the coax to power it (which I draw from my radio or SA). The antenna works well from 45 MHz to about a 1 GHz, but does a decent job on 2.4 GHz on hot signals. Above about 1 GHz though it is helpful to use a wave guide (1-18) pointed out a window (I clamp mine to the headrest and cover it with a straw hat) and then drive around the area. Since the wave guide will also "suck in" signals below 1 GHZ I can get fairly decent coverage from 800 MHz to about 22 GHz which is fine for my initial scans. Below 45 MHz I have had good luck with active loops, but they are none too subtle. I have had my best luck by simply mag mounting an omni-directioanl antenna to the vehicle roof in the exact center, and ensuring a good electrical ground. -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

The manual I have (TM 11-6625-3240-14, June 15, 1993) is vague as to whether this is a "wet" or "dry" line TDR- I've always used the 1502-B with a BNC coaxial protector, but the trade-off is a slight tilt in the display.... I'd like to hear comments on "homebrewing" protectors for the 1502-B as well as comments on other smaller TDRs with specs better our equal to the 1503-C/YT or 1502-C/YT (The 1502 is costlier, has a higher resolution, but only goes out to 2000 feet or so. The 1503 family go out to 50,000 feet on some wire types. The B and C versions have an LCD display and hardly resemble the early 1502 and 1503s.) Thanks, Jay Coote Los Angeles 140 From: James M.

DO NOT, REPEAT DO NOT use this instrument on "live" telephone lines. I would point out that VR3021 and VR3020 are 5.6 volt diodes on the front end, and that they will "go poof" if you apply loop voltage for anything more then a few seconds. The A6 Ethernet Board bumps these voltages up a bit, but still no where near the voltages found on normal phone lines. In the event that you are lucky enough to have the TDR connected when ring voltage is applied you can expect to damage the unit (which will permanently degrade performance, but not kill the unit). The unit is designed to handle PERIODIC applications up to 400 volts, but it is ill-advised to every apply more then 11.2 volts or you will get screwed up readings. If you get into a pinch and have to use a 1500 series on a wet line then add a cap in series to kill the DC, and a couple of switching diodes to kill anything over 6 volts (and of course a set of zeners). A small impedance matching circuit will also be helpful. Remember the 1500 was designed (many years ago) to test the cabling on antenna's, not telephone loop circuits. -jma =================================================================== Sed quis custodiet ipsos Custodes? =================================================================== James M.

Arigato. 142 From: Dawn Star Date: Thu Apr 6, 2000 10:46am Subject: Jay, I have a Tektronix 1503 that I've been using since 1980. Its range goes for miles if you know the tricks. It really kicks butt. In 1985 I busted a bunch of federal wiretaps with it and they threw me in jail and set my bail at one million dollars. How's that for certifiable results. Roger P.S. I've used this unit on over 2500 sweeps (25 to 50 lines per sweep) all on active trunks with ring-in's all the time - this unit never misses a beat - and its power lies in using it on active lines including station lines within the local system.
