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?

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!

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...). AO-16 telemetry 3 Oct 2010 1838 utc PACSAT MBL Telemetry Decoder Ver. 1.3 (c) Mike Rupprecht, DK3WN =============================================================================== (average values) +10V Battery Bus : 0.00 V Battery Charge Reg : 0.55 mA Base Temp : 9.07 °C PSK RF Out : 1.90 W +5V RX Bus : 4.87 V +8.5V RX Bus : 8.49 V +10V RX Bus : 11.24 V Here is another teaser :) Several months ago I commanded the AO-16 S-band transmitter ON; it too remains functional (albeit weak), and was received by me, Drew KO4MA, and Alan WA4SCA. 73, -- Mark L.

OUFTI 1 identified
by Nico Janssen 05 May '16

05 May '16

All, Detailed doppler measurements show that OUFTI 1 is object 41458, 2016-025C. The separation between AAUSAT 4 and e-st@r-II still is less than 4 km, so it is not possible yet to identify them. It is remarkable how slowly they drift apart. 73, Nico PA0DLO

AMSAT at ARRL Nevada State Convention - "halftime" report
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Apr '16

30 Apr '16

Hi! Things are going well for AMSAT here at the ARRL Nevada State Convention ("NVCON") in Las Vegas. Except for one thing - the weather. It has been raining here all day, sometimes hard. Frank N7ZEV and I have been working at the AMSAT booth, talking about satellites, and showing off different things on my tablets. You can see more about that, including photos, on my @WD9EWK Twitter feed - or visit this link: http://twitter.com/WD9EWK If the weather breaks later this afternoon, we'll look to do some demonstrations outside before the convention closes at 6pm (0100 UTC). The convention continues tomorrow until midday (around 1900 UTC), so there may be some chances to do demonstrations then - assuming it's not raining tomorrow morning. 73!

Upcoming trip - Nevada activations
by Kevin M 30 Apr '16

30 Apr '16

Hello all, Just a heads up that I will be leaving out tomorrow morning (Sunday May 1st) for a three week trip that will hopefully include some satellite operations. I plan on being in Nevada from May 8th through the 15th. Among the places I'd like to operate from are DM16, DM07/08/17/18, DM27, DN00/10 and DN01/11. Also possibly DM28 or DM19. Another op told me that he plans to operate from DM19 on May 7th & 8th. Will check with him afterwards and see how he did, then decide my exact plans. For those that want more details, please see my special webpage on QRZ: https://www.qrz.com/db/N4UFO/P I have a map, pics showing locations and a detailed explanation of my plans on that page. There is a link to a special 'rover' twitter feed where I will send out information as I can (spotty coverage in Nevada) and you can watch for that information by simply saving the link and checking it regularly; no twitter account is required. I also have a special e-mail account while on the road and there are links to follow my travel progress via APRS, provided my signal is getting out to the network. It was suggested that when I announced my plans, I should clearly state my objectives. My operations on this trip are intended to pass out grids to as many people as possible that need them and some of these are rarely heard grids. To that end, I would like to request that if you need the grid, please call me, but please be brief with your calls, be courteous to other callers and try your best to only work me ONCE per grid. And if you already have a grid confirmed, it would be considerate to leave the precious airtime for others that need it. (If I am working a grid line or corner and you need at least one of the grids, by all means call me!) I would like to further ask that folks do not blind call me, do not call me if I temporarily lose the bird and please do not 'tail end' on others working me. I am running 5 watts or less. If someone starts calling me, you will likely be PREVENTING me from getting into the bird. (And when one person calls, others tend to start calling, compounding the problem.) On FM, your signals may cover mine, preventing me from getting in (even if no signal is being heard - two or more signals can clash and nothing gets through). And on the linear birds, a loud signal (anywhere in the transponder) may turn on the AGC limiter and raise the receive threshold, preventing me from being heard despite being heard just a few moments earlier with the same power settings. (Calling on the 'tail end' of another QSO can cause this as well.) I am not traveling alone and satellites are not the primary purpose of this trip, thus, I have other things to consider; so please be understanding if my plans vary a little bit. I will also try to operate from 'the road' from a few grids squares along the way out & possibly the way back as well. That will mostly be on an ad hoc basis, but if I think I might be able to stop somewhere of interest, I will try to give notice of the possibility, ahead of time. Again, best to watch my twitter feed. More details on all this are at the QRZ page linked above. Good luck to us all, happy hunting and I look forward to working everyone "from the high desert!" - 73, N4UFO P.S. For those that asked, no I will not be going to the Area 51 gates. X^D But I WILL try to operate from the Little A'Le'Inn parking lot.
