Fwd: [aprsisce] Re: Eclipse Umbra Path [1 Attachment]
by Robert Bruninga 24 Aug '17

24 Aug '17

My HT on a rubber duck just north of Georgia picked up 12 APRS balloons during the eclipse . When I got home, I counted 244 APRS Balloons on Eclipse day on FINDU.COM. Subtracting out the 96 from other parts of the world that day left 148 over the USA. But looking at the map, I only could find about 46 along the track? Where were the others? I cant get a plot of all the USA ones since the filters on APRSFI wont work that big. Looking for someone who can plot all the APRS balloons that day on one map? Mark, KE6BB posted a plot of all the "Flight" symbols during the eclipse. Most are balloons, but a few aircraft mixed in as well. But Ill have to post it on a web page to share it with the group.

Upcoming satellite workshop on Saturday, August 26th
by christy hunter 24 Aug '17

24 Aug '17

Ruth, will give it a go from DM14. and thank you for your demo. The exposure can be invaluable to those few that are inspired to chase satellites. Clint's K6LCS demo many years ago did it for me, then Patrick's (WD9EWK) first response to my call during my first demo during a JOTA clenched it. Thank you to all you Elmers out there. 73 Christy KB6LTY >/On 24 Aug 2017, at 11:34 am, Ruth <ruthwillet at att.net <http://www.amsat.org/mailman/listinfo/amsat-bb>> wrote: />//>/Hi all, />//>/I will be giving a satellite workshop this Saturday August 26th for the Amateur Radio Club of Columbia County in Georgia.

SDR# I/Q file of AO85 Telemetry
by Wendy and Terry Osborne 23 Aug '17

23 Aug '17

Does anyone have a SDR# I/Q wav file of AO85 Telemetry? AO85 (Fox-1A) should have a downlink that can be copied with an RTL-SDR Dongle. In this part of the world, you need to trigger the repeater to turn on the Downlink and so far I haven’t been able to do this. The 2 minute timer is a bit like chasing a needle in a haystack. I’ve tried Patrick, WD9EWK’s HDSDR files but can get any decoded data. 73, Terry Osborne ZL2BAC

ISS Repeater Clarification
by Richard Lawn 22 Aug '17

22 Aug '17

Just to clarify, the downlink is 145.800 and uplink is 437.800? Is there a tone. Someone posted the wrong uplink frequency I think and I just monitored a wonderful pass with lots of great signals heard in FN21. I was unable to hear myself and suspect I had the wrong uplink frequency. Thanks for clarification 73 Rick, W2JAZ

ISS Repeater Audio
by Scott 21 Aug '17

21 Aug '17

Hello everyone. For those in the U.S., I hope you had an enjoyable eclipse day. As has been reported, the voice repeater on the ISS was (is?) active today. If anyone has not had an opportunity to hear the audio when that configuration is enabled, here is a short section of this evening’s pass if you are curious about the quality, etc. (I wish my cell phone was this clear!) http://www.qsl.net/k/k4kdr//files/2017-08-21--ISS-repeater.mp3 ... the audio would have actually been even more clear, but my antenna pointing was a compromise between the ISS and some nearby cubesats. 73, -Scott, K4KDR Montpelier, VA USA

Activation of CO80 Whistler BC
by Chris Wilford 21 Aug '17

21 Aug '17

To all AMSAT-NA bird chasers; I am now on a family vacation in Whistler, BC (CO80) from now until Saturday August 26th. It will be a vacation schedule but will try to hit multiple passes a day. The focus will be on FO-29, AO-85 and SO-50, but I may jump on any pass that works. I will post details before passes on my twitter feed (@VE7CEW). You don’t need a twitter account to follow my tweets just go to: https://twitter.com/ve7cew I have no idea yet how low I will be able to work in this mountain surrounded village but will try to find the best possible route to cover as much as I can. Feel free to PM me or email if you want to try a specific pass or just want to let me know to listen for you. 73. Chris VE7CEW CO80 Whistler, BC

Re: [amsat-bb] NO-84
by Richard Ferryman 21 Aug '17

21 Aug '17

I have been firing APRS through NO-84 for the last three days and was logged on almost all passes here in UK. However I notice the downlink signal is a lot weaker than ISS so I assume it is running much lower power. As a result I don't hear all the downlink transmissions. I don't know what the power difference is. Dick G4BBH --- This email has been checked for viruses by AVG. http://www.avg.com

AMSAT NEWS SERVICE ANS-232 The AMSAT News Service bulletins are a free, weekly news and infor- mation service of AMSAT North America, The Radio Amateur Satellite Corporation. ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * Cubesats Deployed During Russian EVA - TOMSK TPU-120 Reported Active * Pat Gowen, G3IOR, Silent Key August 17 * AMSAT Fox-1B Completes P-POD Integration * AMSAT Phase 4 Groundstation Update Report * AMSAT 2017 Symposium Call for Papers * AMSAT Journal Packet Articles Added to Station and Operating Hints Page SB SAT @ AMSAT $ANS-232.01 ANS-232 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 232.01 From AMSAT HQ KENSINGTON, MD. DATE August 20, 2017 To All RADIO AMATEURS BID: $ANS-232.01 Cubesats Deployed During Russian EVA - TOMSK TPU-120 Reported Active News on the AMSAT-UK webf described the hand-deployment plans of three Russian Cubesats during a spacewalk this week: Expedition 52 Commander Fyodor Yurchikhin, RN3FI and Flight Engineer Sergey Ryazanskiy, of the Russian space agency Roscosmos, conducted a planned extravehicular activity from the ISS on Thursday, August 17. Ryazanskiy began the schedule of extravehicular activities with the manual deployment of five nanosatellites from a ladder outside the airlock. The satellites, each of which has a mass of about 11 pounds, have a variety of purposes. [the satellites are thought to include Tanyusha-SWSU 1 & 2 and Tomsk-TPU-120] One of the satellites, with casings made using 3-D printing technology, will test the effect of the low-Earth-orbit environment on the composition of 3-D printed materials. Another satellite contains recorded greetings to the people of Earth in 11 languages. A third satellite commemorates the 60th anniversary of the Sputnik 1 launch and the 160th anniversary of the birth of Russian scientist Konstantin Tsiolkovsky.

Pat was the amateur radio operator who made the discovery on June 21, 2002 that AO-7 was transmitting again. Pat posted a message on the amsat-bb, "I have just come across something most remarkable this Friday 21st June evening. Checking out interlopers in our 145.800 - 146.000 MHz space band with a new vertical now atop my 60' tower and working like magic, at 1728UTC I came across a beacon at S.7 sending slow 8 -10 wpm CW on 145.973.8 MHz. It slowly Dopplered down to 145.970 MHz before going out at 1739 UTC." Pat's original message and follow-up replies can be accessed in the amsat-bb archives: http://www.amsat.org/amsat/archive/amsat-bb/200206/msg00525.html [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- AMSAT Fox-1B Completes P-POD Integration Tuesday, August 15 Jerry Buxton, NØJY, Vice President Engineering, delivered RadFxSat, our AMSAT Fox-1B CubeSat, built in partnership with Vanderbilt University to Cal Poly University. RadFsSat/Fox-1B was successfully integrated into the P-POD cubesat deployment container on August 16 along with her pod-mates Makersat-0 and EagleSat. Launch qualification vibration testing of the integrated P-POD was completed on August 17. The P-POD will next be mounted on the ULA Delta II rocket for launch no earlier than October 12, 2017. At the conclusion of integration and testing Jerry commented, "Many thanks to the Cal Poly, Tyvak, and NASA personnel who we performed the integration with, to the Makersat-0 and EagleSat team members, and to my west coast AMSAT CubeSat wing man Al Vasso for a successful and fun day!" Look for photos and more news to be published in the AMSAT Journal. RadFxSat/Fox-1B Uplink: 435.250 MHz FM (67.0 Hz CTCSS tone for access) Downlink: 145.960 MHz FM (with subaudible slow speed telemetry data) 145.960 MHz 9600 baud FSK data [ANS thanks Jerry Buxton, NØJY, AMSAT Vice President Engineering for the above information] --------------------------------------------------------------------- AMSAT Phase 4 Groundstation Update Report Michelle Thompson, W5NYV has published this week's AMSAT Phase 4 Ground Weekly Report - video here: https://www.youtube.com/watch?v=FZxGfh1Es_I&feature=youtu.be The video provides photos and full discussion of the Team's report. Below is a summary of the highlights, editted for the news format of the e-mailed ANS bulletins. So there's quite the backlog. Let's get caught up. We have a True Position GPS 10 MHz reference with Arduino and display. A very nice system for the money, and we have a session scheduled with the local microwave club to get them up and running for some Phase 4 Ground receiver development. LDPC decode work took some strides forward primarily due to Charles Brain G4GUO and Jan Schiefer AC7TD. Check out the repository in the notes. There will be some more updates there very soon on-line at: https://github.com/phase4ground/DVB-receiver Two B200s compliments of Ettus Research have been delivered to Phase 4 Ground members for R&D. Wally Ritchie WU1Y and Mike Sprenger and Tony Stone W4UOO & W4TAS are the current responsible parties and are learning and doing. This very generous donation is greatly appreciated. If you are in the market for a lab-grade SDR, then go to Ettus and tell them Michelle W5NYV sent you. We're making progress on receivers for DVB-S2 in GNU Radio. We demonstrated the current smoking pile of various blocks at Hamvention, and then Maker Faire, and then DEFCON. We will next bring our work to GNU Radio Conference in September, hopefully that same weekend at TAPR DCC, and then we will bring what will by then be a complete and perfect flow graph to AMSAT Symposium in October. An added bonus? If we can swing it, we'll bring all the wireless challenge exercises from GNU Radio Conference to AMSAT Symposium and be on hand to teach anyone that wants to learn how to use GNU Radio to solve them. Oh, and there's another Maker Faire in there somewhere and I think we should set up a booth. If you're in or around San Diego, Maker Faire will be at Balboa Park on October 7-8. I have a tower trailer for traditional demonstrations but I'm looking to show off satellite, SDR, and digital microwave. We will have Phase 4 Ground members at Microwave Update, IEEE conferences, GNU Radio Conference, TAPR DCC, and AMSAT Sympsosium. Most of these conferences will have papers and/or presentations. If you have never been to any of them, please check them out. These are some of the premier annual events for various overlapping technical communities. We had a very successful Hamvention. Visit https://youtu.be/vHI96TRXchk for a great video of our Hamvention AMSAT engineering booth! Thank you to EC1AME for posting this. We had an extremely successful DEFCON. Phase 4 Ground promoted AMSAT, SDRs, and GNU Radio to one of the largest and most enthusiastic crowds we've ever seen. This was the 25th anniversary of DEFCON, in a new location, and we were invited to be a part of the Wireless Village for all three days as an anchor exhibit and demonstration station. This was a very successful outreach by any measure and we are already planning for next year. If you can help with the GNU Radio DVB-S2 receiver blocks, then do it now because we need more people working on it to make quick progress. Other areas of activity are Phase 4 Ground support of the wireless signal intelligence competition, or CTF, at GNU Radio Conference, and a hackable amateur radio themed badge project. Steve Conklin is coordinating and his first deadline is a February hardware hackers cruise out of San Diego. Next stop after that, Hamvention 2018. If you are interested in badgelife, Bluetooth, integrating VHF/UHF into a hackable wearable badge project, then do we have a challenge for you. Phase 4 Ground will also be at Burning Man. An upcoming video will focus on what we learn from our desert hackathon. The focus will be on getting ahead on DVB-S2 receive and coming up with challenges for the GNU Radio CTF. If you have not got your ticket to GNU Radio Conference, then please do. Link in the notes. www.gnuradio.org Besides producing a radio for AMSAT five and dime, we all want to show how truly fun SDR and GNU Radio and embedded devices and digital communications really are.

It is sad state of affairs when some jerk in the USA decided to exploit my gift to the satellite community Seems there are some vindictive jeulous people out there The IP Address hack came from a comcast business customer in California I was forced to lodge an investigation with comcast business in the USA TCPIP 50.255.43.233 50-255-43-233-static.hfc.comcastbusiness.net When I contacted their online support the clueless individual had no idea what to do. This has made me think twice about helping the satellite community in the future http://59.167.159.165 <http://59.167.159.165/>

Monitoring satellite telemetry during solar eclipse
by David G0MRF 20 Aug '17

Hi all. 1 day to go and I hope your weather forecasts are good! Looking at a few of the available satellites, it seems that the best opportunity for one of them passing through totality is the AO-85 pass that begins over Alaska in the NW at 19.07 UTC and then passes down across the path of the eclipse just off the Coast of GA and FL at 19.22 UTC If you are in the South East USA then you should be able to pick up telemetry as it passes through or very close to totality.. AO-73 + EO-88 both transmit real time telemetry every 5 seconds and they see a partial eclipse. The exact percentage is a little difficult to predict but the graphs produced on their ground station 'dashboard' software should show some 'eclipse effects' The sun sensors on AO-73 produce a graph of log Lux against time. If you happen to get some good results, please get a screen grab of the graph or save the tlm file. It's always good to see the effects of these rare events on the satellites. AO-85 19.07 to 19.27 Best at 19.22 UTC AO-73 16.33 to 16.26 Descending pass via UT AZ CA EO-88 18.12 to 18.24 Descending west coast and for a satellite's eye view... https://apod.nasa.gov/apod/ap990830.html 73 David G0MRF
