Building stuff is what I'm here for, and I'm heavily engaged in >that. These satellites don't just build themselves. If you choose not to get involved with YOUR organization, then don't post on amsat-bb someday wondering why there are no more satellites available for you to "play radio" with. For some, this may be "just a hobby", for those who volunteer to serve AMSAT with their personal time and effort, it is much more than "just a hobby". I believe that every volunteer comes to AMSAT to serve the cause of keeping amateur radio in space, but may see different ways to move the organization forward toward that goal. There is a Board election coming up very soon. Like all elections, it behooves you as a good citizen of AMSAT to be informed of the issues and make a wise choice in voting for your elected representatives. As my high school civics teacher (and probably yours) said, "if you don't vote, you don't have a right to complain". 73, Dan Schultz N8FGV

Any 2.4 GHz satellite beacons over US?
by k.swaggart＠charter.net 12 Jul '20

12 Jul '20

Looking at JE9PEL's SatsList at http://www.ne.jp/asahi/hamradio/je9pel/satslist.htm I see there are seven satellites listed as active with at least one of their beacons near 2.4 GHz: 14781 UO-11 2401.5 (steady carrier) 43804 Suomi-100 2410.0 43786 ITASAT-1 2400.15 43743 Reaktor Hello World 2410.0 43669 Tiayni-4 2409.0 43155 Tiayni-2 2403.0 42775 AALTO-1 2402.0 Are any of these routinely active over the western US? And, any sat beacons in the 10 GHz band? 73, Ken, W7KKE

Proposal for new list
by Zach Metzinger 12 Jul '20

Hello all, I propose that a new list be created, separate from amsat-bb, for discussion of administrative issues regarding AMSAT. This would improve the SNR of amsat-bb for those of us who just want to play radio and work satellites. Thanks, --- Zach N0ZGO

Jerry, Very nice to hear a update on HO-107. We appreciate you and the engineering teams hard work on the LTM module projects. Do we know why HO-107 got to 80c other then the full illumination period? Would there be a way to mitigate that in the future or is it just something that has to be dealt with? I know AO-85 suffered a similar fate of heat stroke but lasted many years. Looking foward to seeing AMSAT partner with many others to get the LTM module into orbit. Regardless of it only working 3 months, it is still a rousing sucess that will lead to many more launches with other partners. Thanks, Nick KE8AKW

Modeling the AA2TX Parasitic Lindenblad
by Zach Metzinger 12 Jul '20

12 Jul '20

Hello folks, I've been intrigued by Tony's Parasitic Lindenblad ever since I first read about it. I have a center section in CAD, suitable for 3D printing in PET-G, which eliminates the messy gluing, etc. and gives me a chance to use my printer. :-) However, I'd like to eliminate the requirement for the 0.750" OD aluminum mast and replace it with 0.650" OD (name: 1/2") copper water pipe, which can be readily found in any hardware store. Given the appropriate paint coating, copper pipe has held up well over many years at my QTH when exposed to the elements. I am using Xnec2c on FreeBSD, but any NEC program should be able to use the deck, to model the antenna. However, my dimensions don't seem to match what Tony came up with. Are there any NEC gurus in the audience? Here's my sophomore stab at the antenna deck: CM --- NEC2 Input File created or edited by xnec2c 3.4 --- CM AA2TX Parasitic Lindenblad -- All distances in meters CM Goal is to use 1/2" copper water pipe for dipole element (0.650" OD) instead of 3/4" OD aluminum pole CE --- End Comments --- GW 1 15 0.00000E+00 0.00000E+00 -1.39000E-01 0.00000E+00 0.00000E+00 1.39000E-01 1.58750E-02 GW 2 15 2.58000E-01 8.50000E-02 1.49000E-01 -2.58000E-01 8.50000E-02 -1.49000E-01 1.50000E-03 GW 3 15 -2.58000E-01 -8.50000E-02 1.49000E-01 2.58000E-01 -8.50000E-02 -1.49000E-01 1.50000E-03 GW 4 15 8.50000E-02 2.58000E-01 -1.49000E-01 8.50000E-02 -2.58000E-01 1.49000E-01 1.50000E-03 GW 5 15 -8.50000E-02 2.58000E-01 1.49000E-01 -8.50000E-02 -2.58000E-01 -1.49000E-01 1.50000E-03 GE 0 0 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 EX 0 1 8 0 1.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 FR 0 20 0 0 4.30000E+02 1.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 NH 0 0 0 0 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 NE 0 10 1 10 -1.35000E+00 0.00000E+00 -1.35000E+00 3.00000E-01 0.00000E+00 3.00000E-01 RP 0 19 37 1000 0.00000E+00 0.00000E+00 1.00000E+01 1.00000E+01 0.00000E+00 0.00000E+00 EN 0 0 0 0 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 0.00000E+00 Questions that arise from an afternoon of fiddling with this: 1) Should I model the driven element as two wires with the 1/4" gap between them?

Any and all comments, especially from NEC gurus, appreciated! --- Zach N0ZGO

Elect New, Honorable, Board Members
by Brad Smith 11 Jul '20

11 Jul '20

<Amen. Let's get this off the list and back to playing with radio.> We need a board that we can trust and this board is not trustworthy to led,nor spend the finances in aan ethical manor. I have received emails from members, on both sides of the issue. One asked me how I know the moneys spent were donations. So, I now ask the Board, where did the funds ($18 k) come from that you spent to bury Patrick and Michelle? 73 Brad KC9UQR

Spending the funds to address the issue for which these funds were expended, to develop policies and procedures to help handle and prevent such problems like this from ever happening again in the future is money well spent. You and Patrick are the ones that need to reimburse the membership for the expenses. KB7ADL

The Explanition Has Come
by Brad Smith 11 Jul '20

11 Jul '20

The email, "AMSAT Leadership Explains 2018-2020 Legal Expenses," which I assume all members received, made me think of the words of an oldie song that has the words, "I wish that i could be the president, so I could show you how your money's spent." In this case, it appears that the money was spent to, at the advice of hired layers, keep two duly elected directors from assuming their rightful role. So, the legal answer must have been to segregate them, into a second class status. Is this really legal, and in keeping with the bylaws of AMSAT? Why would the board do this? What are they hiding and from whom? I may be just a dumb, retired, Midwestern engineer, but even I can see thru this one. Talk about smoke and mirrors. I am going to assume that it was legal for the board to select a new president, and that the membership has nothing to do with that. This whole situation has the appearance of a game where people have been trying to find a way to legally block other people from assuming their duties. Sounds like Washington politics to me. Some members have resigned their membership over this. I am here to say that I do not condone this form of reaction. In my humble opinion, (and some of you know how humble I am) if you are on the birds, you should financially support the organization. Exception would be if one couldn't afford it, of course. Respectfully,Brad KC9UQR

How does one change one's yearly membership to Life Membership? I cannot find any method to do so on the launch.amsat.org web pages. And I cannot rejoin as such either. Bob W7OTJ
