I think so :o) Just received a brief e-mail from Ghislain LX2RG, the project manager of the 4M payload. The e-mail just says "It's working !" 73 Jan-Louis F6AGR Le 23/10/2014 18:39, David Jordan a écrit : > > Jean-Louis, > Any word on the launch?

VIBE table available to government agencies
by Robert Bruninga 23 Oct '14

23 Oct '14

Our vibe system is available to other government activities. You do the paperwork… It is only a few years old, is working fine. But we got another one – bigger. We needed one to provide a full 20G vibe on a 3U cubesat. This one can only get to 20 g on a 1U. Here is what it looks like: http://www.labworks-inc.com/general_purpose_systems/lw127_123-500D12.htm I have no idea how things get transferred, but I am certain that our comptroller will only let us transfer it inter-agency. So if you are not somehow able to get a government transfer, please don’t bother asking. And we are still waiting to see if any other department on campus wants it. This thing is big. The image on the above web page has a 19” half-rack for the amp as shown on the left, but the image of the VIBE table itself is at HALF that same scale in that image. SO it is actually twice as big, about 4’ long, 3’ high and 2’ wide and very heavy half inch steel, double the size shown. Bob, WB4aPR

Re: [amsat-bb] Going Digital Someday

How about fldigi? It offers several modes, not too many, but allows for some room for everyone to explore their favorite mode..... Other software programs can run these same modes, but if we promote the one package (fldigi), we hope to limit the mides to a few popular modes rather than a free-for-all....... Just a thought.... Open to anything myself....

Now, can AMSAT official support this mode, maybe help/encourage the developers and start to implement it (testing) on for example FO-29? What about a digital mode for the FM satellites? One of the big frustration I have is to decide which one of the digital modes to pick. What is beautiful about this hobby is the diversification which now also becomes the "curse" with promotion and competition of various commercial and open source modes/codecs. Maybe we can help and focus on one "system" for amateur satellite use and get it used/implemented.

Going Digital Someday
by JoAnne Maenpaa 22 Oct '14

22 Oct '14

During the Symposium in Baltimore last week there was a discussion that I found quite interesting. Billed as a proposal for fairly long-term, future AMSAT HEO possibilities, this blue-sky proposal offers projects that will be fun for myself (and maybe yourself) to learn what's next ... or could be next ... It seems the cubesat form factor is here to stay for practical launch opportunities available to us ... (please don't ask for getting a phase III-B form factor in this thread!) Wiser people than myself have assured me of this. Analog SSB and CW modulation in a 3U to 6U cubesat may not be practical at HEO apogee due to antenna size limits on a cubesat and power generation capability of the cubesat limited number of solar cells. Digital techniques were described as a way to make this work. FreeDV HF Digital Voice for Radio Amateurs was one of the types of technologies mentioned just as an example. I found a demonstration at: http://nicktoday.com/freedv-hf-digital-voice-radio-amateurs/ Interesting, eh? A soundcard interface to your existing radio, sound card in the PC, we're teaching ourselves the first steps into digital radio ... getting ready for the future. I've only had to interface my soundcard interface to my Yaesu 857D just once. The interface remains stable from a hardware point of view. My PC runs the appropriate software for FUNcube telemetry, SSTV from ISS and prior ARISSat-1, PSK31, JT65, RTTY ... and when I get some time in between preparing the next issue of the Journal I'll add the software for the FreeDV codec. Perhaps we'll hear more interesting ideas or a fresh approach! At least we could have a thread with some fun discussion ... -- 73 de JoAnne K9JKM k9jkm(a)amsat.org AMSAT VP User Services

TURN to Page 9, schematic diagram Meters M1 and M2 are analog meters in the Control Box. Potentiometers VR5 and VR6, located INSIDE the outside rotator and geared to motor movement, changes resistance -- which is measured and reported on the meters M1 and M2. Dirty or failing potentiometers are common, and required maintenance with heavily used antenna rotators. w9gb Sent from iPad Air

pics from 1998 Symposium

I'm packing up stuff from the Ocean View property and ran into a packet of photos Bill W0oqc SK had sent me from the 1998 Symposium. What a blast from the past. Pics of W0oqc, W0sat, N8ocx, Ki0ag,N7sfi,W5iu,K5vas,Wd5gqm,Kb1sf,W3xo,Wd5gqm,K5nrk. Such great memories of the morning Breakfast club on the FOO birds, FO20, and FO29 with most of these guys and more. Very fond memories.. 73 Jeff kb2m
