Project directory
Hello. The WikiProject Council has recently updated the WikiProject Council/Directory. This new directory includes a variety of categories and subcategories which will, with luck, potentially draw new members to the projects who are interested in those specific subjects. Please review the directory and make any changes to the entries for your project that you see fit. There is also a directory of portals, at User:B2T2/Portal, listing all the existing portals. Feel free to add any of them to the portals or comments section of your entries in the directory. The three columns regarding assessment, peer review, and collaboration are included in the directory for both the use of the projects themselves and for that of others. Having such departments will allow a project to more quickly and easily identify its most important articles and its articles in greatest need of improvement. If you have not already done so, please consider whether your project would benefit from having departments which deal in these matters. It is my hope that all the changes to the directory can be finished by the first of next month. Please feel free to make any changes you see fit to the entries for your project before then. If you should have any questions regarding this matter, please do not hesitate to contact me. Thank you. B2T2 00:29, 26 October 2006 (UTC)

Need advice on how to write new article on SCAM-FM
(This message was moved from the project page.)

Editor,

New Topic called SCAM-FM in radio communications.

I am interested in writing a new fundametal article in FM communications entitrld SCAM _FM and FM demodulation during periods of multipath reception.

Despite some seventy years of research in FM demodulation no-one has correctly analysed the true failure mechanism in multipath distortion. Multipath distortion is caused where the antenna passes through a region of SCAM-FM. This is where the delay echo path is 180 degrees or (2n-1) times 180 degrees and the signal is loss free, the same size as the original incident wave. It is not caused by thresholding. The Rician ot Rayleigh distributions have nothing whatever to do with the problem.

During SCAM-FM events, the carrier is sucked out of the composite carrier plus sidebands, and the origianl FM carrier is transformed into a double sideband Suppressed Carrier Amplitude Modulated Frequency Modulated signal(SCAM-FM). It cannot be demodulated using any standard type of FM demodulator.

These SCAM-FM zones are the fundamental reason for the failure of DAB radio as a transmission technique. The first publication of the analysis has now appeared in the magazine "Electronics World" in the current issue, December 2006. The same mechanism also applies in AM and in all form of digital phase amplitude transmission.

I need advice on how to proceed.

 * Feel free to create the article Suppressed carrier amplitude modulated frequency modulated! There is no editor here. You may start out from the article Single-sideband modulation, and link to multipath. Please have in mind that Wikipedia is not a place for original publications. If possible, please also refer to other than your own publications. When you are happy with the article, you may add a link to it for example at the modulation page, and at the Wikipedia:WikiProject Telecommunications project page.

Suggestion: List of deployments
XDMA is a mobile technology that uses XDM multiplexing to provide something or other resembling a phone service.

LIST OF DEPLOYMENTS
Armenia


 * Aadvark Telecom has deployed XDMA since 1972
 * Apple Mobile recently launched it's XDMA network in 1892
 * Armenian Mobile has announced plans to launch an XDMA network, sometime in 2098
 * Aztec Communications has deployed XDMA in most major markets, and plans to cover 90% of Armenia in 2020
 * Azzup!, the popular brewery/telecommunications conglomerate, uses XDMA in its pubs
 * Borat Export launched a XDMA network in 2006. Unfortunately it's in Kazakistan.

...snip...

Albania


 * Albaninet upgraded its network to XDMA in 1981
 * ABC Telecom has deployed an XDMA network in Tirana but refuses to sell any phones
 * BCA Telecom, ABC's rival, has launched an XDMA network everywhere except Tirana
 * CBA Telecom, a joint venture of ABC and Vodafone, has launched an XDMA network in the South

...snip...

United States of America


 * Alltel recently bought an XDMA network when it bought Defunct Wireless in 1961.
 * Cingular launched an XDMA network in 2002
 * Sprint is building out an XDMA network which it hopes to put online in 2005
 * US Cellular upgraded its network to XDMA in 1973.

...snip...

(etc)

Is it just me, or should we, perhaps, be moving the massive lists of deployments in articles like UMTS, HSDPA, EV-DO, WiMAX, and others, to separate pages? I think the information's kind of useful, but it's enormous and not necessarily what we'd run over to a technology page to look at. A more useful entry would be something like:

Real World Deployments
Since Vodafone UK's original roll-out in 1792, XDMA has been adopted by a number of carriers across the world, spanning 2196 countries, and is in use by an estimated 56 billion people.

You could even merge some of the deployment lists. HSDPA could appear under the UMTS deployments list for example.

Anyway, that's my suggestion Squiggleslash 00:36, 13 December 2006 (UTC)

Wikipedia Day Awards
Hello, all. It was initially my hope to try to have this done as part of Esperanza's proposal for an appreciation week to end on Wikipedia Day, January 15. However, several people have once again proposed the entirety of Esperanza for deletion, so that might not work. It was the intention of the Appreciation Week proposal to set aside a given time when the various individuals who have made significant, valuable contributions to the encyclopedia would be recognized and honored. I believe that, with some effort, this could still be done. My proposal is to, with luck, try to organize the various WikiProjects and other entities of wikipedia to take part in a larger celebrartion of its contributors to take place in January, probably beginning January 15, 2007. I have created yet another new subpage for myself (a weakness of mine, I'm afraid) at User talk:Badbilltucker/Appreciation Week where I would greatly appreciate any indications from the members of this project as to whether and how they might be willing and/or able to assist in recognizing the contributions of our editors. Thank you for your attention. Badbilltucker 18:24, 30 December 2006 (UTC)
