The trade name is CardKey, and the supplier told our executive that it was the "latest state-of-the-art" equipment. The cards do not need to be passed through a reader, just within 6 inches of the box on the wall. The system records the time, date, door, and the serial number of the card (read employee.) I am curious how this technology works if anybody out there in cyber-space would like to share this info. Perhaps I am being paranoid, but I also suspect that the device can read a card much farther away, i.e., it could track an employee's movements even if the employee did not use it to operate the door.

I built one of the Ramsey 40-m QRP transmitters--really simple, about half a dozen components. When it didn't work, I figured I'd done something wrong, and would trouble-shoot it when I got the chance. Haven't yet gotten the chance, but it sounds like the problem may not have been me. This discussion thread may provide me incentive to see just what was wrong (oscillator works, but not the final), but also to homebrew rather than buying another Ramsey kit. -- John Taylor - W3ZID rohvm1.mah48d@rohmhaas.com ------------------------------ Date: 7 Jan 94 02:05:18 GMT From: netnews.upenn.edu!iat.holonet.net!bwilkins@rutgers.rutgers.edu Subject: Repeater database?

The next attempt will be Thursday, January 6 at 2100 UTC. If the weather is still not favorable, further attempts will be made Friday, Saturday, and Sunday at 1500 UTC. The Utah Balloon Team is a cooperative group from Utah State University, Logan, Utah, members of the amateur radio community, and Winzen International. The nylon superpressure balloon for this flight is 76 feet in diameter. It was manufactured and donated by Winzen International of San Antonio, Texas. The expected daytime float altitude of this helium filled balloon will be 120,000 ft (36,660 meters). Some loss of altitude is expected to occur at night and regained during the day. Theoretically the technology is capable of maintaining a payload at altitude for long periods of time, potentially years. PAYLOAD - The payload will weigh 4 kilograms, or 8.8 pounds. It will consist of the following subsystems: 1. A primary data payload containing: - A five channel Magellan GPS receiver - An external air temperature sensor - An internal payload temperature sensor - A battery voltage sensor - A differential pressure gauge - A 1/2-watt VHF MCW telemetry transmitter - A one-watt 15-meter telemetry transmitter - A black-and-white CCD television camera - A UHF ATV transmitter. 2. A cutdown package containing a VHF command receiver, DTMF decoder and barometric switch. 3. An ultra lowpower secondary data payload onboard containing a 60-milliwatt 10-meter CW telemetry beacon. 4. Three Lithium battery packs: one for the primary payload, one for the secondary payload, and one for the cutdown package. OPERATING FREQUENCIES - The balloon can be monitored on the following frequencies: 145.871 MHz (1/2-watt): MCW telemetry beacon with a four-minute on cycle and a 15 minute sleep cycle. This transmitter will operate with the call sign of N7YTK, transmitting data from instruments listed above. (This transmitter will also operate through the Russian RS-10 amateur satellite, which has a downlink frequency 29.371 MHz, plus or minus Doppler.) 21.229 MHz (1-watt): CW beacon on the same duty cycle and sending the same data as the two-meter telemetry beacon, with a call sign of WB8ELK. (It will also operate through the Russian RS-12 amateur satellite, which has a downlink frequency of 29.429 MHz, plus or minus Doppler.) 434.00 MHz (1-watt): Black-and-white ATV using a CCD camera. ATV will be available intermittently as commanded from the ground. 28.322 MHz (60-mw): CW telemetry sent every minute. This secondary data payload will have the call sign of WB8ELK, and will transmit pressure altitude, internal temperature, external temperature and battery voltage. MISSION PURPOSE - The purpose of the SuperBall 1-94 mission is to certify this superpressure balloon technology for long-duration flight and to test our ability to control and receive data from a high-altitude research balloon for an extended period of time using amateur radio. Our first plateau of success on this mission will be achieved if we operate through a complete sunset/sunrise cycle at a constant pressure altitude. Our second plateau will be a flight lasting a week. Our third plateau will be a complete circumnavigation of the globe. Anything after that is gravy. Observers from the Jet Propulsion Laboratory, Martin Marietta and Utah State University's Space Dynamics Laboratory will be present at the launch. These people are potential users of the superpressure balloon for a Martian mission. Gil Moooe, N7YTK, plans to chase the balloon for the first 24 hours to make certain that we have good telemetry and video through one sunset/sunrise cycle and to handle cutdown if required. After that, data retrieval will be performed by hams in the flight path footprint, as coordinated by net control, John Luker, KA7QBC. FLOAT PATH - The float path of the balloon is very difficult to predict since the polar breakout usually occurs is this time of year frequently resulting in strong north south currents. It is currently our best guess that SuperBall 1-94 will in the initial few hours, as it ascends through the lower atmosphere, move rapidly (50 to 100 knots are possible) to the east toward the southwestern Wyoming border, but as it enters the calmer air at 70,000+ feet it will follow a slow (2 to 7 knots) western track from Logan, over Elko, Nevada; Reno, Nevada; San Francisco, California; and from there out over the Pacific. If the balloon shows no threat of interfering with controlled airspace, as it reaches the coast, it will be allowed to continue on its journey. We are assuming at this point an east to west path at an average speed of 5 knots. We will leave the rest you your imagination. HF NET AND QSL'S - An HF net will be conducted by John Luker, WB7QBC on the day of the launch, and subsequent days on 7230 KHz +-QRM. This net will alert interested hams down range of the balloon's path, and coordinate the collection of telemetry. A special QSL card will be sent to those who provide copy of telemetry or beacon reports. Please send this information to John Luker, WB7QBC@uugate.aim.utah.edu. If you do not have access to email you may also mail, via SnailNet, reports to John's home: 1226 W 725 N, Clearfield UT 84015.and will advise down-range listeners of the latest developments. He will also post this information on an Internet special interest area called "balloons" for those who can telnet to uugate.aim.utah.edu. The Utah Balloon Team would appreciate the forwarding of any telemetry copied to John's address along with pertinent information, including the receiving station's location, UTC date and time, signal report, and receiving equipment. Video tapes of any received ATV transmissions from the balloon would also be appreciated. At this point we only anticipate turning the camera on during the first two days, but command access to the ATV system by down range hams is available by requesting the frequency and DTMF codes from Gil Moore, N7YTK (internet gilm@sysdiv.sdl.usu.edu). The camera will be pointed up at the balloon rather than the ground on this mission since our main concern is the condition of the balloon. TELEMETRY FORMAT - The modality of the telemetry will be Morse Code and depending on the band will be either CW or FM-MCW. The exact data block layout will be posted as a bulletin on internet balloons@uugate.aim.utah.edu sometime shortly after launch. (The format was being changed at the time of this writing.) MISSION UPDATES - We will continue to do periodic computer predictions based upon the telemetry we receive back from the on board GPS receiver and information from NOAA. We will be depending largely on down-range listeners to provide this information to us as rapidly as is possible. We do NOT plan on a chase beyond what Gil has planned for the first 24 hrs, obviously, since we would like to let it fly as long as possible.

If you don't believe me, put a radio next to your terminal. It's radiating plenty. Inadvertently perhaps, but still enough to tax. What? You won't tax it because it doesn't radiate enough? Well what about Joe QRP over here, who is running a few miliwatts with a transmitter powered by rotting tomatoes? How can you tax him? It just gets so difficult to devise a law to do what everybody expects it to do that it either gets thrown away or turns into an unenforceable mess. And hey, maybe it'll encourage QRP operation?
