Still, we do have one advantage over the commercial guys - most of our payloads are small and lightweight. 73 de VK3JED / VK3IRL http://vkradio.com

Thank you AO-51 for your service. May your cells one day short so that you may come back to life. Until then, RIP. Also, thank you to the AO-51 team for all your extraordinary work from start to end. AO-51 is the bird that got me into satellites. -Reid N0RC

FT-847 For Sale
by Sebastian, W4AS 29 Nov '11

29 Nov '11

First, no I'm not getting out of the hobby, or satellites for that matter, I'm just replacing the old, with the new. I have for sale my Yaesu FT-847 transceiver, it's one of the 'newer' models that works fine with computer assisted control. It also has the CW filter. I have the original box, manual and hand mike. The FIRM price is $925 shipped, CONUS. Contact me directly if you are interested and would like to see pictures. 73 de Sebastian, W4AS

WD9EWK @ Mesa AZ hamfest, Saturday (3 December) morning
by Patrick STODDARD (WD9EWK/VA7EWK) 29 Nov '11

29 Nov '11

Hi! I will have an AMSAT table at the Superstition Amateur Radio Club's annual hamfest on Saturday morning, 3 December 2011. This hamfest is in the southwestern parking lot of Mesa Community College, along the east side of Dobson Road between Southern Avenue and the US-60 freeway's exit 177 in Mesa AZ. More information about the hamfest is available at: http://wb7tjd.org/hamfest/ During the half-day event, WD9EWK will be on satellites for on-air demonstrations. AO-7 should be in mode B, and there will be passes on SO-50 and VO-52 that I should be able to work. If you hear me on those passes, please free free to give me - and the hamfest crowd - a call. For AO-7 and VO-52, I tend to start out about 10 kHz above the center of the passband, +/- for other activity and QRM. If I hear no responses to my CQ calls, I will move around and try to work whoever I hear on the passband. Maybe even in CW. The hamfest officially starts at 0530 local time (1230 UTC), and I hope to be set up to work passes starting around that time. As with my other satellite activities, I will be happy to confirm QSOs made during these demonstrations. I will upload the QSOs to LOTW shortly after the hamfest, and will mail out QSL cards for anyone wishing to receive one. There is no need to first send me a card and SASE - just e-mail me the QSO details. If you are in the log, I will mail a card out to you. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

satellite radios
by Jim White 29 Nov '11

I would appreciate info on what the currently available satellite radios are. We have used the IC-910 and FT-736R for some time and now need to recommend a radio to a couple of groups building cubesats. The 736 is of course long gone but it appears the 910 is also no longer made. We recently helped a group who had bought a TS-2000 and I was not particularly impressed with it as a satellite radio. So what's current and what works well on V and U? Jim jim(a)coloradosatellite.com

Re: satellite durability fm vs. linears
by Andrew Glasbrenner 29 Nov '11

29 Nov '11

I don't think there is much difference when you look at ALL the failed and operational sats. BTW, FO-29 is inoperative, HO-68 was both FM and linear, and you forgot DO-64 in recently failed transponders. AO-27 is 17? years old. Satellites come and go. I still miss SO-35, RS-10/11, RS-12/13, FO-20, UO-14, SO-41, AO-10, and of course AO-40. The point is we have to continue to build and launch new ones, and use what we have at the moment. "Love the one you're with" for those who remember the song. Looking in the near term, we have P3E, Kiwisat, Fox-1 and -2, UKube, FunCube, Turksat-3U, the planned SA-AMSAT cubes, and others that need our support to get to orbit. 73, Drew KO4MA -----Original Message----- >From: zach hillerson <qstick333(a)yahoo.com> >Sent: Nov 29, 2011 10:48 AM >To: "amsat-bb(a)amsat.org" <amsat-bb(a)amsat.org> >Subject: [amsat-bb] satellite durability fm vs. linears > >Serious question regarding satellite durability.

Fw: ARRISat-1/RADIOSKAF-V/KEDR
by Farrell Winder 29 Nov '11

29 Nov '11

Nothing heard from ARISSat-1 this AM 15:04 Z Nov 29.. Did anyone hear signals from 145.930 or 145.950? Pass was very short over Cincinnati this AM and El only 2 deg.. Will try again Wednesday Nov 30 at 13:43 Z but believe eclipse will prohibit sat to be active. From: Farrell Winder Sent: Monday, November 28, 2011 1:16 PM To: AMSAT Subject: Fw: ARRISat-1/RADIOSKAF-V/KEDR No success today Nov 28. Will set up again tomorrow Tuesday Nov 29 for the AOS 15: 04 Z Cincinnati pass. From: Farrell Winder Sent: Sunday, November 27, 2011 7:31 PM To: AMSAT Subject: ARRISat-1/RADIOSKAF-V/KEDR All, With the research and recent "heads up" by Mineo Wakita, JE9PEL, Allan Biddle, WA4SCA and Clint Bradford, KCLCS it appears there may be only a few weeks left to receive and experiment with ARISSat-1/RADIOSKAF-V. On Monday Nov 28 I will be set up to receive voice, CW and SSTV via the transponder on 145.930 MHz +/- doppler. This will be on the AOS starting at 14:47 Z pass over Cincinnati. This pass may be too soon after the eclipse so the sat may not be activated. If it is active, I will try to send a couple of SSTV R36 transmissions. I will be listening and looking for others to send also. Farrell Winder, W8ZCF Cincinnati, Ohio.

Satellite Satire
by K4FEG 29 Nov '11

29 Nov '11

OK I have a suggestion: a new inexpensive satellite, It will be designated: *ReNe-Sat-3, *that will be an abbreviation for: *Red Neck Satellite #3 ( Dale Ernharts Sr. NASCAR #). *We will take 2 Woxun HT's, 2 Larsen Mag-mounts, 2**1/4 wave antennas, a solar panel with charger from Northern Hydraulics and last but not least about 100 feet of NASCAR 200mph duct tape. We take the 2 radios set them up for our frequencies, duct tape them together mount the antennas on the solar panel hook the solar panel up to the HT batteries and last but not least we send two of the south's finest: *Astronaut "Bubba & Cooter"* up with the new bird to deploy it. We will tell Bubba & Cooter that they can have free passes to all the NASCAR races for 2012 when they get this satellite working and in orbit. I promise they will have that thing (or should i say "thang") up and running in HEO and be back before the first race in February 2012. For those that are not sure, YES I AM MAKING A JOKE! /*It is difficult work to keep these satellites working and the control operators deserve a round of applause from us for all that they have done to extend the life of AO51 and all of the other birds. THANK YOU ONE AND ALL! A JOB WELL DONE! */ Frank K4FEG
