SSB is just one of the many modes of emission standardized in radio communications, its used by the amateur radio service (ham) , the citizens radio service (cb), the military, etc ... The real problem is that to build any sort of network would require some fixed positions, which, if it were intended to be 'clandestine' would be compromised sooner or later ... either that or several poor shnooks would have full time jobs driving vans around and around to keep the RDF snoops guessing ... In general there would be a better chance of pulling it off if you stayed away from the ham radio bands. 'self-policing' is not a character of another bands except the commercial broadcast bands. Spread spectrum would have more promise as many stations could be on the air at once on the same frequency thus making life quite confusing for the T-hunters. Brian B.

Re: Clinton's fake apologies

If nothing else, Clinton deserves his troubles because he is a very strong supporter of the legal structures that caused them. 1) He is a lawyer and a strong supporter of the trial lawyers who have promoted extremely expansive civil discovery of the sort that allowed Clinton to be questioned about Monica in the Jones case. 2) He is a strong advocate of the sort of sexual harassment law that led to the Jones case. He thinks it should be punished harshly. A real feminist. 3) He is a strong advocate of the Ethics in Government Act and pushed its renewal through Congress in 1994 when the Act was going to expire and when the Dems controlled both houses of Congress. 4) He is a law-and-order liberal who believes in executing retarded murderers and jailing hospital execs who submit Medicare bills based on misunderstandings of detailed and contradictory regulations. 5) His wife (and presumably he) was a strong supporter of an expansive definition of "high crimes and misdemeanors" during Watergate.

No mention of whether the computerized software in the device, of the GPS link and its satellites are Y2K compliant. ------- Army Tests Land Warrior for 21st Century Soldiers By Jim Garamone American Forces Press Service FORT BELVOIR, Va. -- American soldiers and Marines are already among the most deadly in the world, but a system called Land Warrior will soon make them unmatched. Land Warrior integrates small arms with high-tech equipment enabling ground forces to deploy, fight and win on the battlefields of the 21st century. "Land Warrior soldiers fight as a system, and the most important part of the system is what's between his ears," said Army Lt. Col. Robert Serino, Land Warrior product manager. Land Warrior came about in 1991 when an Army study group recommended the service look at the soldier as a complete weapon system. The first priority in Land Warrior is lethality. The second is survivability and the third, command and control. The program will cost $2 billion when 45,000 sets of the equipment are fielded between 2001-2014. The Marine Corps, Air Force and many foreign countries are interested in the system. "First and foremost, Land Warrior is a fighting system," Serino said. Land Warrior has several subsystems: the weapon, integrated helmet assembly, protective clothing and individual equipment, computer/radio, and software. The weapon subsystem is built around the M-16/M-4 modular carbine. It has a laser range finder/digital compass, a daylight video camera, a laser aiming light and a thermal sight. "This system will allow infantrymen to operate in all types of weather and at night," Serino said. In conjunction with other components, a soldier can even shoot around corners without exposing himself to enemy fire. The integrated helmet assembly is lighter and more comfortable than today's helmet, Serino said. It has a helmet-mounted monocular day display, a night sensor with flat panel display, a laser detection module, ballistic/laser eye protection, a microphone and a headset. The protective clothing and individual equipment subsystem incorporates modular body armor and upgrade plates that can stop small-arms rounds fired point-blank. It includes an integrated load-bearing frame, chemical/biological protective garments and modular rucksack. The infantryman will attach the computer/radio subsystem to his load-bearing frame. Over this goes the rucksack for personal gear. The computer processor is fused with radios and a Global Positioning System locator. A hand grip wired to the pack and attached to the soldier's chest acts as a computer mouse and also allows the wearer to change screens, key on the radio, change frequencies and send digital information. The subsystem comes in two flavors: The leader version has two radios and a flat panel display/keyboard, and soldiers have one radio. With the equipment, leaders and soldiers can exchange information. Soldiers using their weapon-mounted camera, for example, can send videos to their leaders. Finally, the software subsystem includes tactical and mission support modules, maps and tactical overlays, and the ability to capture and display video images. The system also contains a power management module. Designers set up the system so it can be updated as technology improves. The soldiers who will actually use Land Warrior have been consulted every step of the way. Prime contractor Raytheon worked with experts at the U.S. Army Infantry Center at Fort Benning, Ga., in designing the system. They have taken the system to the users to ensure the system is headed in the right direction. For instance, Serino said, "The rucksack has quick-release straps so an infantryman can just drop it if the need arises. This is what our soldiers asked for -- which is really great." One problem the Army must overcome before fielding is power. Current batteries last about 150 minutes with all systems running. "Clearly soldiers won't have all systems running all the time, but this is still not acceptable," said Serino. Other batteries under development by the Army's Communications-Electronics Command may push the time up to 30 hours. The Army plans to test the Land Warrior system with a platoon from the 82nd Airborne Division, Fort Campbell, Ky. Later, a battalion-sized test is planned, Serino said. "Ultimately, soldiers will define the end state of Land Warrior -- and we'll know more every time the soldiers employ the system," he said. "We'll get the system up to a certain point, then the soldiers will be the people who say how far it can really go." ----------------------- NOTE: In accordance with Title 17 U.S.C. section 107, this material is distributed without profit or payment to those who have expressed a prior interest in receiving this information for non-profit research and educational purposes only.

SSB xceivers cost <$700. Try any marine electronics store. Best choice is a ham xceiver with strap selectable SSB (actually a violation of FCC dictate to enable SSB on a ham rig, but everyone does it anyway). This would cost ~$1500, the Icom 7658 is a good one I know of. Go and get your local equivalent of a VHF license, send in the extension to cover SSB (~$50). Then purchase a 'PacRat' from any ham hangout. I got mine in Redwood City CA, on El Camino real - some years back now though. This is a little box that hooks into the back of the ham/SSB set and into a serial port of your PC. It comes with some basic packet handling software. Last time I looked, PacRats were <$200. Don't expect any great xfr rates however. Noise to signal requires many packet retransmissions as the ionosphere is not a very good mirror. Running TCP/IP over it should be easily doable. Basic use is to dial in the frequency yourself on the SSB (this usually requires an auto-tuner ~$700 AND a manual tuner ~$100, for best results). You need to get the best antenna you can afford. Unfortunately, antennas are frequency range specific, so you'll probably need 3: one for 0-5000 miles, 5000-12000, 12000-?. Its easy to rig the tuner to support 2-3 antennas, switch selectable. You need a Good Earth for anything to happen as expected. By now it should be possible to get some extra SW to drive the freq selection, so you could do spread spectrum. This is not allowed of course, as you are expected to do the call-sign exchange protocol on each freq session. There are freqs that are dedicated to digital (ship-to-shore commercial). You may have to get a commercial license for this though. One nasty thing about radio is that you share the spectrum with others, so collisions tend to make a hash out of reliability. Store and forward at unpopular times such as 3:00 EST, could be a good alternative. The longer distance freqs (>12000), are the most uncluttered, but suffer from the most noise to signal. A bounce across the pacific to the house next door, would be potentially more reliable than a lower freq. Most of the ham sets also support FM, so it would also be possible to piggyback on the ricochet freqs for line of sight use. Or for a real adrenaline rush, piggyback the mil freqs. If you really want to give the hams fits, write a noise to morse engine (or better yet, some captured call signs repeated endlessly) and swamp the channels, where the old popular mechanics guys discuss their antenna envy, at random intervals. 9:00 in the Ozarks is a fine time. Sit back and wait for the black vans to drive up. "Educate, don't Agitate"

How about a line-of-sight (LOS) infrared network, a neighbor-net? Always thought this could be a method for a local technical entrepreneur to fund and share their personal T-1 link or for some small network enterprise to avoid local and US federal regulations and compete with the big cable and telephone companies. Appears that LOS infrared is currently unregulated and could be encrypted. Get enough people in a neighborhood to put LOS infrared relays on top of their houses, allow them to tap in, and feed this neighbor-net from some central point that is equipped with a more conventional link. I dunno why infrared, which theoretically has much more capacity than a phone line or coax cable, seems currently so slow, i.e., less than 10 MB in many commercial offerings. Ive no cost estimate for the roof top boxes. Heavy wet weather, fog, rain, snow obviously can affect LOS infrared, esp. low power. Personally, I would like more choices than just the phone and cable lines, especially something that is locally controlled. However, I imagine that if any significant traffic was generated over such infrared or wireless neighbor-nets, the Feds would eventually step in and regulate them. They'd probably want to regulate the traffic over a taut string, between paper cups.

They can cut and paste manually, or, probably best, they can go to another ISP. I understand what you're saying, Ryan, and I understand what they're saying, but there all alternatives out there; they just don't want to use them. In fact, they've installed proprietary packages that do this. There are plenty of free alternatives out there which don't have this problem. If my ISP pushed a bunch of proprietary software down my throat, I'd find another ISP. That goes double if the proprietary software sucks. That goes triple if the software sucks and the ISP is trying to get every idiot they can to use it. (I got a "100 hours free network abuse" disk in the mail recently from AOL.) Another AnonMonger
