What is this all about? We will never be able to explain the philosophy of "free software" as well as the GNU people do. So look at the license for the general idea and, if you are so inclined, take a look at http://www.gnu.org web site for in-depth discussions. In simple terms, though, the reason for this is that as soon as these sorts of programs get into the world of commerce, they are given a cloak-of-secrecy, all efforts for information exchange cease and the spirit of the project is lost. You need to help keep this from happening!

In addition, as a member of the "community," you will need to share any changes that you make to the programs. We will try to help to get this information spread about to interested users.

BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

CREDITS - (This is a personal note from W7PUA, the program coder). I will probably forget someone here, but I must attempt to thank and credit the many people that have helped during this project. Johan Forrer KC7WW, has been of great help with the DSP side and has graciously shared his wizardry in real time DSP programming. The LMS code also came from Johan. Kirk Bailey N7CCB has supplied ideas throughout the project and improved the product in many areas. Gary Oliver WA7SHI has contributed ideas and programming wisdom in the area of weak signal DSP going back to 1987 when he wrote a 32010 assembler because nothing was available within ham budgets. Andy Baranski, PE1ROE, has provided many useful ideas and lot's of fun discussion. Bob Rullman K7MSH, Deane Kidd W7TYR and Merle Cox W7YOZ have all helped with the weak signal ideas. Conversations at the Microwave Update in Phoenix have certainly been influential. The same goes for the recent Mars Global Surveyor (MGS) relay experiment where this equipment and software was used to detect the spacecraft at 437 MHz. Various people on the MGS net were informative and helpful. The GIF routines from Sverre Huseby, the ASYNC routines from David Kessner and the DSP loading routines EZLD and EZFAST from Dwight Elvey all were great time savers. Analog Devices has provided considerable assistance through their application manuals.

After the initial issue at version 1.6, Ernie Manly, W7LHL, Beb Larkin, W7SLB, Larry Liljeqvist, W7SZ and Mike Reed, KD7TS, have spent huge amounts of time beta testing versions of both programs. This has included discovering a wide range of "bugs" that I introduced. They and their computers all survived the experience and the usefulness and relatively good reliability of the programs is in a major way attributable to their efforts. Roger Rehr, W3SZ, has provided considerable assistance as well as a broad perspective in applicability of this technology. The influences of Wes Hayward, W7ZOI, Roger Hayward, KA7EXM, Rick Campbell, KK7B, Ed Hare, W1RFI, Russ Carpenter, AA7QU, and Paul Pagel, N1FB, show up in many places in this project. The credits would not be complete without acknowledging several individuals that had no contact with the project, but influenced it in major ways. Starting with Jack Wolf, an NYU EE professor of the early 1960s who introduced me to all the concepts involved.Then there were the developers of the Piccolo project, pioneer weak signal experimenter Victor Poor, K3NIO, and the two amateurs that collaborated with me in many non-coherent-integration experiments of the early 60s, Carl Scheideler, W2AZL and Bill Ashby, K2TKN.

Many if not all of the links you follow from page to page will open in a new browser window. There a few links that are within the same page, but not many. This can be a source of memory drain in the PC, but most files (pages) are small and should not cause problems. If you are simply browsing around, it would be wise to close unused browsers when you are done on that page.. While editing this documentation I have had up to 17 browsers/composer windows open simultaneously with no difficulties other than the associated confusion.

Some of the links are to sections within a page, and appear to open in the middle of something. This is not the case. The top line displayed is the start of the linked information.

Just be aware that there will be new browsers opening, and often there is no need to "go back", because the original page is still there. Just close any browser windows when you are done with them.
