I am involved in an as yet to be approved or funded project called the GIANT array. It seems that several of the cosmic ray experiments have seen some very high energy events. Of order 3E20 electron volts or the energy of a well thrown baseball. It turns out that by theory such events are not possible unless they originate very near to our galaxy (Well, within 50 mega parsecs - if you call that "near") as they should be slowed down to of order 1E18 by interaction with the 3 degree background. Astronomers do not see a likely candidate nearby. So there is a real mystery. A "cosmic ray" is a single something coming in from outer space. Those with higher energy hit atoms in the upper atmosphere and create secondary particles. The secondaries hit other particles, etc., and the ones we are looking for finally result in of order 1e17 particles spread out over a few tens of square miles. The final particles are a mix of muons, electrons, and gamma rays. The mix is determined by the original particle which is most likely a proton or an iron nucleus. Which one it might be is very interesting to physics, so the experiment is designed to sort this out by attempting to time and identify as many particles as possible. To study these events an array of detectors is planned. The present design calls for 3000 detectors each about 10' by 10'. The detector will likely be a scintillator, lead, scintillator sandwich. We call them Leadburgers, which distresses our leader who is a little too straight to appreciate the humor, but he is coming around. The top scintillator detects muons and electrons, the bottom scintillator detects muons and gamma rays. The Leadburgers will be spaced on a 1 mile hexagonal grid. A roughly 3000 square mile device - so we think the term GIANT is appropriate. The whole mess will be placed out in a desert somewhere and there will likely be two - one in each hemisphere. Obviously we will not be able to afford to string power lines between all these units, so they must be solar powered. This means very low power electronics. We will synch them all together (GPS has been suggested though I think we can do with less) somehow, to 50ns or better. The plan has been to use packet switching and time division for transmission so that there would be no two stations that could hear each other broadcasting at the same time. (We plan to avoid the collision problem by precisely timing all transmissions since we need to know time accurately for the measurement.) Thus the reason I was attracted to this news group. As we talk about it, when one detector sees something that might be part of a giant shower, he calls up his neighbors on his cellular phone and asks them if they saw something too. If they agree that an event has occurred, it is then passed from station to station until it reaches the control room. All this is supervised by a computer (again low power) resident in each detector. Because the people involved think that way, the project will be done on a shoestring. At the moment we have no money, and I am working for the fun of it. In the end, we hope to do the whole project for of order 50M. So far our leader has done pretty well rounding up the few hundred thousand needed to bring physicists from around the world to our design study so I am optimistic that we will get to do the project if we do a good job of design. The initial design study will be carried out during the first six months of 1995 at Fermilab (near Chicago). It will be a world wide collaboration with physics representatives from Australia, UK, Germany, France, Russia (various former republics), China, and our leader (a Nobel prize winner) is even visiting Viet Nam to try to get really universal support from the physics community. Obviously, the work is not classified. We are presently building and testing the instrumentation that will go into the Leadburgers. We would soon like to do some of the radio transmission tests that will help guide the design here at Fermilab. We also hope to build a few station prototype here. While those involved have experience with most things, and indeed it is the pride of the physics community that they can do designs of most things on the back of an envelope from first principals; we have little experience with radio transmission. It is obvious from reading this group that Motorola is in our back yard, and someplace there is the experience and talent that we need. Also the amateur radio community could help us a lot. I am therefore looking for someone that would want to join in this project and give advice and perhaps even do some work. An amateur that wanted to work with us would be very useful during preliminary tests if his license can be used for the experiments. Here is an example of what I would like to test right now. We need to know the exact time of arrival of the events. This is used to determine the particle path and thus where it comes from. 100 nanoseconds and 1.5 kilometer spacing gives a path to one degree. We would like to do somewhat better. We already know from tests in Europe, that GPS receivers can give time to a few tens of nanoseconds. Putting a GPS receiver on each Leadburger is a bit expensive and takes a lot of power which is also expensive. So we would like to perform some tests with a central tower going tick, tick, tick, and set up a pair of receivers, phase locked loops, etc., and see how well we can match time in a pair of receivers spaced some distance apart. It is not very likely that a helper will get paid any more than I am at the moment. In particular, this is not the kind of project where there will be a lot of pork to be grabbed up by some political tagging of funds. That is what killed the SSC. Hopefully we can keep this project small enough so that the porkers do not come after us. So there is no big profit to be expected for a commercial enterprise. We hope there is "GLORY" however, and think that a commercial venture might want to be identified with this project. I personally am near retirement, and plan to make this my entertainment for some time to come. Cosmic ray research has rarely been the hot physics topic, so workers are here because they like it and are having fun. After many years of high pressure project work at Fermilab, this looks like fun to me. I really like the people involved. Let me know if you are interested, or know someone that is interested. Lots of good technical paper material. Lots of glory. Lots of fun. No money. (Not quite so bad, if we get the project there might be travel to Australia or Chile or wherever the southern hemisphere device goes - or even pay for real work.) Please do not think that you do not qualify just because you don't have some degree or other. We have all the degrees we need, what is needed is some good experience and smarts that can keep us from making a dumb mistake. You will find as I have that the physicists are quite willing to explain what you will need at your particular level. As an engineer, I have long noticed that physicists do not talk to each other in complex mathematical notation as they know they will not be understood.

It's still the most popular modem when sending data over any type of radio link. The reason being that the 202 is the ONLY modem which does NOT require a full-duplex (ala phoneline) audio path to hear the modem at the far end before it considers itself connected. The reason why 1200/2200 FSK still remains popular with the amateur packet community is that it works and is presently the ONLY commercial modem standard that does work! -- Karl Beckman, P.E. < If this English language is so > Motorola LMPS.RNSG.Analog Data < precise, why do you drive on a > (Square waves & round corners) < parkway and park on a driveway? > Any opinions expressed here do not belong to or represent Motorola Inc.

I believe they do use phase modulation on each frequency, since they are set up to send 0,2,4,6, or 8 bits per baud, per frequency. Given the earlier comments about HF propagation, something similar but without the phase stuff (i.e. 1 bit per baud) might be interesting, then restrict the width to the number of distinct frequencies that can fit in 500Hz.
