TeamSpeak conference for Tuesday 16 Jan
by Jim Sanford 16 Jan '07

16 Jan '07

Team: I'm sending this out by email because I'm having some difficulties with the TS page on EaglePedia. Things I'd like to discuss: 70cm RX status How many prototypes to build Goals for 2007 My partial goals are: Prototype 70cm RX and 2m TX Demonstrate above, with some form of SDX prototype Demonstrate prototype IHU-3 and CAN widgets Structure design and model Refine microwave phased array plans Peer review, test, demonstrate text messaging Begin development of integration plan and composite test plan Develop Work Breakdown Structure (WBS) leading to a preliminary development/construction schedule The last item is clearly mine; Gould has been helping me on the WBS. Obviously, once I've laid it out, I'll need your comments and then some schedule estimates. I think that we are now at the point where it's time to define a schedule of what is reasonably achievable so that we can begin to make construction/integration/launch plans. Please add to the goals; this is just my first cut. Please also add to topics. I've asked for help on my issue with EP; will advise as soon as the agenda is posted there. Thanks & 73, Jim wb4gcs(a)amsat.org

Is there any interest in a copy of the "Proceedings of the 1st Annual USU Conference on Small Satellites"? It is among the papers in my office that will soon see the circular file unless someone wants to rescue the document.

FINALLY back on the air
by Robert McGwier 13 Jan '07

13 Jan '07

We finally solved the major cause of the 35 year old electrical problems here at home and I am back on the air here after a 3 day absence ( 7 AM Thursday to 2:30 PM Saturday). The problems we found are direct contributers to everything from computer problems, to light bulbs burning out way too fast, to pool pumps causing the house to brown, and on and on that we have been experiencing. As I kept upgrading appliances and adding new toys, the situation deteriorated until I was forced to solve it. Anyway, I am back to where I can answer email at last.

SDX, MRAM and Radiation
by Lyle Johnson 04 Jan '07

04 Jan '07

Hello! I have heard anecdotal assertions that MRAM (see < URL:http://www.freescale.com/mram >) is inherently SEU immune from radiation, or at least very tolerant. Does anyone have any knowledge of this? I ask because the Freescale part is pretty tempting, even if its standby current drain is a little high. Thinking in terms of SDX here... 73, Lyle KK7P

A wild thought
by Jim Sanford 03 Jan '07

03 Jan '07

Team: I've been thinking about this for a while. Recent publicity for Eagle in multiple publications has resurrected the thought, so I seek your comments. I'm considering seeking, for each discrete peer review, an additional review team member from AMSAT membership at large. Heretofore we've collected peer review teams from a subset of Eagle team members with possibly a few known additions. I'm considering seeking a single at-large reivewer from within AMSAT MEMBERSHIP. In my vision, I'd go out to amsat-bb and ANS and solicit qualified volunteers. Such volunteers would have to be verifiable members of AMSAT-NA or another AMSAT organization, and would be asked to send me a resume or c.v. I would use these to select the MOST qualified volunteer for a single at-large position on the peer review team. (I say that I would make the selection, mostly to keep the additional admin burden off you; if any of you want to help me choose, thanks!) I would be responsible for forwarding that individual all necessary materials to do the peer review. I would be responsible for coordinating with Bob and Eric that that at-large member would have access to the AMSAT Engineering channel on TeamSpeak for that particularl peer review (the password changes for each discrete topic.) The advantages I see in this: -- furthers our "openness" with deeds not words -- gives motivated new talent an opportunity to share their expertise with us -- gives us a chance to evaluate, select, and motivate new talent -- advances general membership "buy-in" -- gives us a better ultimate product --may lead us to new Eale team members! I see no down-side to this. If you do, please advise ASAP. If you think this is a good idea, please let me know also. If you have any ideas on how to make the peer review process better, I'd like to hear that as well. I'd like your responses by Friday 5 January. If we decide to proceed, I'd lke to include this in my next Journal article, which will be written this weekend. Finally, I hope to convene a peer review of the UHF receiver ATP soon. For obvious reasons, I intend to use the same team which did the UHF receiver design peer review, plus a couple of additions (w2gps and n4hy) plus the at-large member, unless you convince me the latter is a bad idea. Thank you all, and very 73, Jim wb4gcs(a)amsat.org

Peer Review
by Matt Ettus 02 Jan '07

02 Jan '07

I think the peer review proposal is a great idea. However, I'd suggest making the request for volunteers in the journal and not on AMSAT-BB. One could argue that the statements "is qualified to conduct technical peer review" and "reads AMSAT-BB on a regular basis" are negatively correlated... Matt
