EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

Re: [amsat-bb] Free content from six satellites via Outernet (APRS?)
by Robert Bruninga 29 Oct '16

29 Oct '16

Global Ham channel? We should find someone to work with the OUTERNET folks to add an amateur radio channel to their downlink. Their satellites could provide connectivity to 99% of amateur radio operators on earth. In addition, Ham Radio can bring to OUTERNET an uplink capability that they currently don't have. And the uplink can be from the same remote areas where there is no service... How? Like this. They simply take the APRS packet data stream from the global APRS Internet System (APRS-IS) and stream it in their downlink for hams. Then hams anywhere on earth can transmit traffic via HF back into the system. Since the APRS-IS is one of the world's largest HF receiver-diversity receiver networks in the world, then a packet transmitted from almost anywhere on earth has a reasonable chance of being heard at least once at least somewhere and interjected back into the network, where it gets to the OUTERNET and then in the downlink. The only question, is the atrophy of our HF IGates? Years ago, the HF channel on 10,147.2 MHz had receivers all over the world. I have not listened much recently, but maybe there is still a viable network there. And if not, maybe we could re-invigorate it if it meant global APRS connectivity for ham travelers and hams in remote areas. An HF packet transmitter can be as small as a cigar box and solar powered. Has anyone tuned in the OUTERNET downlink? I have heard anyone with OUTERNET's free ORxPi software and a Raspberry Pi can get the OUTERNET content when plugged into a DVB-S tuner. Then there is of course the arm-chair-lawyers concern of rebroadcast of amateur radio content on a non-ham network? Bob, WB4APR -----Original Message----- From: AMSAT-BB [mailto:amsat-bb-bounces@amsat.org] On Behalf Of Thane Richard Sent: Friday, November 13, 2015 1:22 PM To: amsat-bb(a)amsat.org Subject: [amsat-bb] Free content from six satellites via Outernet Hello everyone, My name is Thane and I lead content and business development at Outernet. Some of you may be aware of us but I suspect most are not. I am writing this email to introduce Outernet to AMSAT. Outernet broadcasts a DVB-S signal <https://wiki.outernet.is/wiki/Coverage_and_transponder_settings> from six different satellites covering 99% of humans on Earth. We created this information service to reach the 4.3 billion people who do not have Internet access and designed it to overcome the problems the Internet presents, namely download speed and recurring cost. Our datacast is completely free to receive, our bitrate is 90 Kbps (~1 GB/day of content), and you can even build your own receiver with a Raspberry Pi <http://store.outernet.is/>. Right now, the content we send is curated by us and a group of editors but we are working on a Reddit/Wikipedia/YouTube mashup where the contents of our broadcast can be decided publicly. Currently, we broadcast Wikipedia, 30,000+ ebooks, PLOS One journal articles, Khan Academy, CK12 textbooks, music from SoundCloud, and more. I want to invite this community to be involved in Outernet and help us build this project. Our current focus is on developing channels to get devices into schools and generally into countries/areas where Internet penetration is very low. Our forum <http://discuss.outernet.is> is very active with users and Outernet staff. Please stop by!

DIY Projects
by Gerald Payton 12 Oct '16

12 Oct '16

This may be OLD stuff to many of you experienced ops., but new to me. I was wondering if there had been any individual DIY projects in the past for building an AZ/EL or Pan/Tilt using robotics? Of course, for our purposes weight and wind load would be a factor. I am not interested in "toy size", as many of the Arduino projects are. If anyone knows of a site or PDF, please send it to me; either here or to my personal email: gp_ab5r(a)outlook.com. I am also good via ARRL and AMSAT using AB5R@xxxx Thanks, Jerry

Pratham identified
by Nico Janssen 04 Oct '16

04 Oct '16

All, Detailed doppler measurements show that Pratham is object 41791, 2016-059J. This is based on the most recent TLE sets, that were published by the JSpOC. Unfortunately the collection of TLE sets for the PSLV-C35 launch is not stable yet. The JSpOC continues to cross-tag TLE sets and to make major changes to some of the TLE sets. So some further changes may be expected in the coming days. The JSpOC has not yet identified any of the objects from the PSLV-C35 launch. It seems quite obvious however that ScatSat is object 41790, 2016-059H. 73, Nico PA0DLO

so-50 hint
by John Papay 30 Sep '16

30 Sep '16

Matt KK4FEM just tweeted about something that happens on SO-50 when you start talking before the satellite gets into the repeat mode. SO-50 is a CTCSS Squelch repeater. You need 67Hz tone to make it repeat your signal. The satellite must decode your signal before it will turn on the transitter. If you start talking immediately, the first letter or two of your callsign will not be heard. If you are not known, others may get your callsign wrong. Those that are full duplex have the advantage of hearing what gets transmitted. Those that are not, don't realize what is happening. So just key up and pause a half-second before giving your callsign. You will have much better results. This does not apply to FM satellites like AO-85 which are constantly transmitting once activated. 73, John K8YSE --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

AO-7 Mode A
by Paul Stoetzer 30 Sep '16

30 Sep '16

It appears that AO-7 switched to Mode A between 0400 and 0600 UTC today. That suggests that the satellite is now in constant sunlight and receiving enough power from the solar cells for the 24 hour timer to stay on throughout it's entire orbit. Expect daily mode switches between A and B to occur for the next three months or so. As AO-7's orbit precesses and the periods of constant sunlight become fewer and fewer, there will be less of an opportunity to use Mode A on a yearly basis, so enjoy it while it lasts! If you don't have a 10 meter antenna up to receive the downlink, try whatever you can. I have used my AlexLoop Walkham Portable Magnetic Loop with adequate results. 73, Paul, N8HM
