Flex-5000 "PA Info" Display Bug During Satellite Operation?
by Bill Bordy, NJ1H 29 Sep '13

29 Sep '13

I have been active on the satellites lately with my Flex-5000 using external transverters. PowerSDR version 2.6.4. I have noticed an error in the PA Info display, Ctrl-Shift-I, when I am in mode B and transmit is enabled. The Temp: will read very unusual temperatures, i.e. 572, intermittently for a moment. Values change, but seem to be repetitive. I have seen large negative F values also. The Voltage: also reads 0 briefly sometimes.The radio appears to function normally when this occurs. This occurs even if the TX Drive is set to 0. I am running SatPC32 V.12.8b to control the uplink and downlink frequencies using x10 Speed. The problem seems to only occur when CAT is enabled on SatPC32. This seems like a conflict between variables used by PowerSDR's CAT control and the PA Info routines. Is anyone else using a Flex-5000 seeing this? 73, Bill NJ1H

Re: Falcon 9 Successfully Launched
by Rick Tejera 29 Sep '13

Years ago I was out telescoping with my astronomy club at a spot about 50 miles west of Phoenix. Just about an hour or so after sunset, we saw this iridescent orange pillar rising in the west. A Delta with a full complement of Solid boosters had just launched. We were able to follow it long after the solids cut out as the sun illuminated the exhaust plume from the main engines. Staging was quite obvious. A Spectacular sight, for sure 73 Rick Tejera (K7TEJ) Saguaro Astronomy Club www.saguaroastro.org Thunderbird Amateur Radio Club www.w7tbc.org -----Original Message----- From: amsat-bb-bounces(a)amsat.org [mailto:amsat-bb-bounces@amsat.org] On Behalf Of Jim Jerzycke Sent: Sunday, September 29, 2013 10:43 To: B J Cc: amsat-bb(a)amsat.org Subject: [amsat-bb] Re: Falcon 9 Successfully Launched Naw, not really. Kinda looked like somebody a few blocks away lit off a firework. If you didn't know what it was, you wouldn't have looked twice at it. Now a NIGHT LAUNCH from VAFB is really something to see! Jim

Re: Phase 3

Hi Dan, OSCAR-10 (P3-B) used the same 400N engine as OSCAR-13 (P3-C) and OSCAR-40 (P3-D). For P3-E we have a 200N motor from EADS Astrium, the same one which is used on the European ATV... I was AMSAT P3-A (planned to be OSCAR-9) which used a solid propellant apogee kick-motor. It's under the water near the cost of french Guiana.. RIP You can find an very good article here: http://www.ka9q.net/AMSAT-Tech-Journal-2.pdf See page 8..15 Rest assured, the PFA and propulsion system was qualified according to highest commercial standards by commercial companies. Thus in no way there would be any risk to the launcher or other payloads. This also includes several levels of safety borders in the hardware design and in the software. The launch agencies have there own specialized personal to review all the details... Without that, nobody would have launched any of the P3 satellites !!! What happened to AO-40 later on after orbit injection and after activating the systems is a completely different matter and did not present any risk to the launcher at any time! Michael R. Lengruesser, DD5ER AMSAT-DL e.V. -- International Satellites for Communication, Science and Education -- mlengruesser(a)amsat-dl.org http://www.amsat-dl.org In einer eMail vom 22.09.2013 21:07:08 Westeuropäische Sommerzeit schreibt n8fgv(a)usa.net: >>The apogee motors for OSCAR-10,and OSCAR-13 were solid propellant >>400 Newton trust motors donated to AMSAT-DL by the Messerschmitt Aerospace >>Company in Germany. Only Phase 3A had a solid fuel motor. AO-10 and AO-13 had liquid fuel bi-propellent motors the same as AO-40. No matter how well designed they are, they still have the potential to blow up the entire launch stack if something goes wrong. Since Dick Daniels is no longer with us, the knowledge has been lost and we will not be launching any more of these in the future.

CASSIOPE's Foldable Antennas
by Bryce Salmi 29 Sep '13

29 Sep '13

I was watching the Canadian Space Agencies BROLL video of the CASSIOPE satellite due to launch in a few days and noticed a neat antenna. The video link below starts at the appropriate point in the video (feel free to watch the whole video too). For what looks like it is essentially steel tape measure metal... that's quite an intense antenna and deployment! I'm used to seeing these on cubesats and other small satellites but this is very neat to see too. http://www.youtube.com/watch?feature=player_detailpage&v=WGD4cWnpcto#t=245 Bryce KB1LQC

Dear Friends, The AMSAT Fox-1 satellite project is in need of an analog circuit engineer to work on our power system. If interested in volunteering, please send me an email with your phone number or Skype and some good times to call you. Note that due to ITAR constraints, you must be a US citizen or have a green card to work on our satellite projects. Thank you and 73, Tony AA2TX

Satellite Explorer Pro iOS app
by Rick Walter 28 Sep '13

28 Sep '13

I use the Satellite Explorer Pro iphone/iPad app. It did work very well on both devices. After the ios7 upgrade, it still works on the iPhone 5 but on my ipad2, the height and max el boxes as well as the data they would contain disappeared. When I open the app on the iPad, I briefly see the boxes and data, then they are gone in a blink of the eye. I tried to find out a way to contact the author with no luck. I hope Thomas Doyle is a ham and monitors this reflector. Anyone else notice the same problem? The settings on both devices are the same. I still chuckle when I see the new Windows commercial bashing the Apple iPad. I have all their devices but agree with the commercial. "Do you think I still look pretty?"

ISShamTV
by Robert C. Campbell 28 Sep '13

28 Sep '13

I am having difficulty getting the software drivers and programs set up properly for my Technotrend S2-1600 PCI and High Sierra down converter. Most everything is ready with the exception of the software/hardware playing nice and my lack of ability to figure it all out. This has been a bigger build than I anticipated and honestly...I am over my head. Is there anyone in the continental US who is at this stage or has over come these problems that can provide assistance? I have left a note on the software developers web in Europe but they work a different sift then we do. Please feel free to contact me at: kb3pmr(a)gmail.com. Also there seems to be a call for participation from our friends on the other side of the pond yet no real contact details. Your input requested. I am still looking for the ISShamTV for dummies had book. Bob
