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

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...).

CAPE-2 heard in France
by Jean-Pierre Godet 25 Sep '15

25 Sep '15

Dear friends from University of loisiana in Lafayette, Your bird was heard in the North of France when flying over Oran (Algeria), orbit number 204, especially the CW beacon (on 145.823 MHz +- Doppler) between 12:12:52 and 12:13:06 UTC, content was "EUL CAPE 2 OR UF231". The signal was somewhat chirpy, but it's exactly the sound which the real lover of CW like above all. Really ! :-) http://f5yg.pagesperso-orange.fr/forum/CAPE-2_orb204_03dec2013.mp3 The signal to noise ratio is not too good because I'm using an old AM/FM scanner from the 80s heterodyned by my medium wave homebrew transmitter fitted with a 456.9 Xtal. The antenna was a vertical half-wave inside the attic. The next orbit, number 205, was heard too, with the CW beacon affected at that time by a hoarse voice and suffering from a strong fadding. So I'm not absolutly sure, poor lonesome telegraphist, of my human decoding, "M5UL CAPE 2 ÜR 5045", something like that. It was over the East coast of Spain, between 12:12:52 and 12:13:06 : http://f5yg.pagesperso-orange.fr/forum/CAPE-2_orb205_03dec2013.mp3 Congratulation to the Cajun Advanced Picosat Experiment team from France !

Good evening, I can report that FUNcube-1 was switched back to autonomous mode at around 21:19 UTC this evening. A reminder for next weekend – As AMSAT-UK is holding their Collloquium event in Guildford Surrey, it is expected that FUNcube-1 will be switched to continuous transponder mode , exceptionally, from Thursday evening (July 23rd) until either Sunday evening (July 26th) or, more likely, Monday evening (July 27th). This will enable the Colloquium attendees to view or demonstrate and enjoy the transponder operations for the maximum possible time. Thanks for your understanding! best 73 Graham G3VZV

Re: [amsat-bb] SATPC32 registration

The program stores the registration code in the file UserDaten.txt in the DATA folder "SatPC32". The path to that folder is shown in the foot line of menu "Satellites". The folder "AppData" in the path is hidden by default. Therefore make first hidden folders and files visible (Windows Explorer - Tools - Folder Options - View).

SDRplay RSP as downlink receiver
by Patrick STODDARD (WD9EWK/VA7EWK) 30 Aug '15

30 Aug '15

Hi! In July, I ordered an SDRplay RSP SDR receiver from the SDRplay web site: http://www.sdrplay.com/ This is an SDR receiver that covers from 100 kHz to 2 GHz without gaps, at bandwidths from 200 kHz up to 8 MHz. There is front-end filtering across the entire range this radio covers - something that caught my eye for use as a satellite downlink receiver with an FT-817ND. At US$ 149 plus shipping from the UK, it is a good value. It is a small box, larger than the FUNcube Dongle Pro+ I have been using for some time. After some issues getting this device working on Windows 8.1 and 10 tablets, resolved with a new API installer, I have been testing my SDRplay on my 8- and 10-inch tablets - now running Windows 10, after being upgraded earlier this month. Over this weekend, after installing the new API and ExtIO drivers needed for HDSDR to see the SDRplay receiver, I wanted to try it to work satellites. I made an attempt on Friday evening, during an AO-73 pass. Although I could hear the satellite, I could not hear myself with the SDRplay and HDSDR. I went back to the documentation and the different interfaces in HDSDR that control the SDRplay, and I figured out the issue. SDRplay's ExtIO driver assumes the user will want to reduce the amount of gain in the receiver, where I want as much as I can get for working satellites. After making some changes, I successfully worked another AO-73 pass this morning. I made two QSOs, with Leo W7JPI in southern Arizona and Brad KG7NXH a few miles/km southeast of me in the Phoenix area. Other than the normal delay I hear from the SDR receiver and software (I hear the same sort of delay when I use my FUNcube Dongle Pro+), the SDRplay receiver did a good job. As I have done when using my FUNcube dongle, I made an RF recording of this pass in HDSDR. That WAV file is big - for an 8:35 recording, it was about 450 MB in size. I also made an audio recording, in the same way I would if I used my second FT-817ND as the downlink receiver - audio splitter plugged into the tablet, feeding audio to both my headset/mic and Sony digital audio recorder. With these tablets, I find that the performance of HDSDR is very poor when it is trying to write both AF and RF recordings. Since I can make an AF recording away from the tablet, I let HDSDR do the RF recording. The default bandwidth used by the SDRplay receiver is 1.536 MHz. It can go up to 8 MHz, but my tablets have issues when the bandwidth is more than the 1.536 MHz default value. When I work our satellites, whether using my tablets or a laptop, I'll probably go with the 200 kHz bandwidth. This is all I really need, and this will help keep the RF recordings from taking over the drives in the tablets and laptop. :-) I have been posting more details about how I have been using the SDRplay to work satellites in a QRZ.com satellite forum thread. That thread is at: https://forums.qrz.com/index.php?threads/sdrplay-as-satellite-downlink-rece… My HDSDR RF recording, along with screenshots and photos of my station, I have put them in my Dropbox space, accessible at: https://www.dropbox.com/sh/6nl39qjkfyw5y5h/AADynnchNPayKAnU0XYwl3TCa?lst I am not planning on selling my FUNcube Dongle Pro+. It is still a good SDR receiver for working our satellites. It is smaller than the SDRplay, it works with the FUNcube Dashboard software, and sales of the dongle support the FUNcube project. It is nice that there is another SDR device that is showing promise as a downlink receiver for our satellites, and at a reasonable price. 73!

Dave explained, "This was not a scheduled contact, I simply answered Christophe's CQ call. I knew it was a good contact at the time, but as I was portable up on Arkansas' Shinnall Mountain, I did not have the resources available to calculate distances. After returning to my office I began to log the contacts I had made, and noticed the estimated distance between EM34 and JN17 was in excess of 7500km. About the same time I came to this realization, my email chirped with a message from Christophe, who had came to the same conclusion." After some quick exchanges, and verifying 10 digit locators, Dave and Christophe have settled on an official distance of 7599.959km between Dave's grid of EM34ST11TL and Christophe's grid of JN17EA22OT. The http://no.nonsense.ee/qth/map.html website was used for distance calculations. Dave concluded, "To the best of our knowledge, referencing data found on Amsat-UK's website (at http://amsat-uk.org/2015/05/06/uk-texas-extreme-dx-contact/) this breaks the previous distance records of 7537.799km between W5CBF and G4DOL, and the 7538.685km contact between K4FEG and DK1TB. Dave had a camera setup to record the pass as well, and you can view a raw clip of the contact here: https://youtu.be/orY0Re0IY30 If anyone has any questions about the contact, Dave will be happy to answer them.

The IARU has informed CAMSAT CEO Alan Kung, BA1DU, that it was only able to coordinate uplink and downlink frequencies for two of the nine spacecraft (CAS-3/XW-2D and E), but it has not made that letter public. CAMSAT has said it plans to launch the nine satellites, all carrying Amateur Radio payloads, on September 7 or 8. "The IARU Satellite Adviser, Hans van de Groenendaal, ZS6AKV, and his advisory panel are mandated to coordinate frequencies within the IARU band plans for amateur satellites," said a public statement released on August 20 by IARU Secretary Rod Stafford, W6ROD. "Coordinated frequencies must comply with band plans that are common to all three IARU regions. Satellites coordinated outside these plans could cause interference to terrestrial amateur operations in other regions." The IARU statement suggested that the popularity and high occupancy of 2 meters "led to a request by satellite builders for coordination outside the spectrum reserved for satellites in the IARU band plans (145.800-146.000 MHz), as not enough channels are available to satisfy their requirements." The IARU said that, in theory, satellites could be programmed only to operate while orbiting above their countries of origin, but "because satellite orbits make it difficult to pinpoint operations, spillover to other regions may occur during parts of the orbit. Accordingly, IARU will not coordinate frequencies for satellites which are planned to operate outside the internationally aligned IARU band plans for amateur satellites." The IARU statement noted that its frequency coordination service aims to "maximize spectrum utilization and avoid possible interference to other satellites and ground stations." The IARU recommended that satellite groups "work on a sharing plan or use other parts of the Amateur Service spectrum designated for satellite operation," and it suggested resurrecting 10 meters - once popular as a satellite band, but largely unused today - as one possibility for uplink channels. "The band segment 29,300-29,510 MHz has been used for Amateur-Satellite downlinks for more than 40 years, beginning with Australis-OSCAR 5 in 1970 and AMSAT-OSCAR 6, AMSAT's first communication satellite, in 1972," the IARU statement noted. Just one amateur satellite actively uses a 29 MHz downlink - AMSAT-OSCAR 7, launched in 1974. Conceding that 29 MHz downlink frequencies "would not be practical for today's very small satellites" due to antenna size considerations, the IARU said the band could be used for uplinks, even with small receiving antennas, because Earth stations can run sufficient transmit power to overcome the disadvantage. "The IARU Satellite Adviser and his panel believe that the 10 meter band offers a good alternative to 2 meter uplinks," the IARU said. AMSAT President Barry Baines, WD4ASW, said his organization's Advanced Satellite Communications and Exploration of New Technology (ASCENT) initiative is exploring alternatives to address the proliferation of CubeSats and the resulting pressure on 2 meters and 70 centimeters. He pointed out that the 200 kHz IARU allocation on 2 meters "is not very wide" given the number of satellites being launched, but the use of 10 meters is impractical in this era of CubeSats. "It is incumbent upon the Amateur-Satellite community to develop new ways of 'keeping Amateur Radio in space' that take advantage of other bands and provide enhanced services through appropriate technologies, given the need to find suitable bandwidth for an increasing number of satellites," Baines told ARRL. He said using digital technology could provide multi-channel capability, and design work is already under way. Transitioning to "underutilized amateur spectrum on bands such as 5 GHz and 10 GHz is also a possibility, Baines added, although he was quick to point out that AMSAT does not intend to abandon use of 2 meters and 70 centimeters for its own satellite projects. The IARU said that when a large group of satellite sharing the same band is launched, "they will soon drift apart which enhances the opportunity to share the same frequencies. For example, during the initial phase, just after launch, a time-sharing system could be used to monitor the payloads before initializing transponders and other systems." "Currently the IARU team also coordinates frequencies for satellites built by universities and educational groups in an effort to maximize spectrum utilization and mitigate any possible interference to Amateur Radio operations," the IARU statement concluded. "The IARU is committed to work with these groups and with the ITU to find other spectrum for these satellites."

TshepisoSat, ZACube-2 is the second instalment in the Cape Peninsula University of Technology (CPUT) F’SATI mission series. The satellite will serve as technology demonstrator for essential subsystems and form the basis on which an innovative Software Defined Radio (SDR) platform will be developed as primary payload. The SDR is highly flexible to address a wide range of communication needs and will be a test bed to validate vessel detection. Additionally, the satellite will feature a medium resolution imager as secondary payload to demonstrate the feasibility of future remote sensing applications such as ocean colour monitoring and large fire tracking. This paper details the conceptual design and highlights the choices made around the proposed development http://www.amsatsa.org.za/ZACube-2%20%20The%20successor%20to%20Africa%E2%80… %20first%20nanosatellite.pdf Read the recent article by Hans van de Groenendaal ZS6AKV in EngineerIT magazine at http://www.ee.co.za/article/cput-planning-successor-africas-first-nanosatel… .html Southern African Amateur Radio Satellite Association (SA AMSAT) http://www.amsatsa.org.za/ [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- ASU Chosen to Lead Lunar CubeSat Mission A spacecraft the size of a shoebox with Arizona origins will soon be orbiting our nearest neighbor to create a map of water-ice on the moon. The NASA-selected CubeSat will be designed, built and operated at Arizona State University and is one piece of the agency's larger mission to fully characterize the water content at the lunar South Pole in preparation for exploration, resource utilization and improved understanding of the moon's geologic history. The spacecraft, called the Lunar Polar Hydrogen Mapper, or "LunaH-Map" for short, will produce the most detailed map to date of the moon's water deposits, unveiling new details about the depth and distribution of the ice that has been tentatively identified from previous missions. Confirming and mapping those deposits in detail will help NASA understand how much water might be available and will help inform NASA's strategy for sending humans farther into the solar system. The ability to search for useful assets, such as hydrogen, can potentially enable astronauts to manufacture fuel and other provisions needed to sustain a crew for a journey to Mars, reducing the amount of fuel and weight that NASA would need to transport from Earth. This is the third major space project for which NASA has selected ASU in the past year, and it is the first planetary science spacecraft mission that will be led by ASU. It represents a major achievement for planetary geologist Craig Hardgrove, the School of Earth and Space Exploration postdoctoral research associate who proposed the mission and will be overseeing it as principal investigator. "All of our previous NASA mission involvement has consisted of us having instruments on other people's missions. This is ASU's first interplanetary mission - this is our mission, our chance to trail blaze," said Jim Bell, professor in ASU's School of Earth and Space Exploration and mission deputy principal investigator. "It's a privilege to be leading this fantastic team, and I want to make sure we do it right and deliver on our promise to NASA," Hardgrove said. CubeSats are part of a growing movement that is revolutionizing space exploration because of their small size and low cost of construction and operation, effectively opening the door to early-career scientists, providing them an opportunity to operate missions of their own. "How much good science can we do with these small missions? We don't know the answer, but we will be one of the first groups to try to answer the question," Bell said. Although this is one of NASA's first forays into deep-space science experiments with CubeSats, the technology isn't new to NASA and universities, which have recognized their value and have been building them for years. "CubeSats are a model for a new way to gain access to space, but they are also a model for how to teach students how to design, build, operate and troubleshoot a real space mission," said Bell, who also directs ASU's NewSpace Initiative. "Students want to know how a spacecraft works, but not just from a PowerPoint presentation. This is their opportunity to build something. Break it. Fix it. Test it again. Launch it. Operate it. And that is the beauty of CubeSats; they provide students with the experience of going through the complete mission process." LunaH-Map will be designed, built and tested on ASU's Tempe campus, in partnership with NASA's Jet Propulsion Laboratory and several other partners supplying space-qualified hardware and services. LunaH-Map leverages technology from at least six small commercial space companies with expert knowledge and experience in building spacecraft hardware: Radiation Monitoring Devices, Busek, KinetX, NASA's Ames Research Center, Catholic University of America, and Planetary Resources. Overseeing all aspects of the spacecraft engineering is the mission's chief engineer and co-investigator, Jekan Thanga, an assistant professor in ASU's School of Earth and Space Exploration. Much of the design and development of LunaH-Map will be done in his Space and Terrestrial Robotic Exploration (SpaceTREx) Laboratory and clean rooms in ASU's state-of-the-art Interdisciplinary Science and Technology Building 4, which with their glass windows offer an opportunity for visitors to watch the spacecraft being built, tested and operated. In total, there will be 15 to 20 ASU professionals, including students, working on all aspects of the design, development, testing and delivery of the spacecraft. "Within the United States there only about seven institutions that are doing interplanetary CubeSat missions," Thanga said. "ASU brings together scientists and engineers to work on radical new concepts together, from the start. This innovative collaboration strategy leads to greater science return, and more creativity and capability." Other co-investigators from ASU include Professor Mark Robinson and Associate Research Professor Paul Scowen from the School of Earth and Space Exploration. LunaH-Map, along with a number of other deep-space CubeSats, is a candidate to fly to lunar orbit on Exploration Mission-1, the first flight of NASA's Space Launch System (SLS), which will be the most powerful rocket ever built and will enable astronauts in the Orion spacecraft to travel deeper into the solar system. NASA will provide several CubeSat missions spots on the maiden SLS mission. LunaH-Map is a 6U ("6 unit") CubeSat. One "unit" is a cube measuring 4.7 inches on a side; LunaH-Map strings six of these CubeSat building blocks together and weighs as much as a small child (about 30 pounds). But just because it is small, doesn't mean it is less sophisticated - in this case, as with our smartphones, size doesn't compromise capabilities. LunaH- Map's design allows for all the necessary sensors and instruments to be securely packaged inside. A jack-in-the-box-like deployer releases the spacecraft and panels pop out like little wings. Once it arrives at the moon, the tiny spacecraft will embark on a 60-day science mission, consisting of 141 science orbits, using a suite of science instruments. Its main instrument is a neutron detector designed to sense the presence of hydrogen by measuring the energies of neutrons that have interacted with and subsequently leaked back out of the material in the top meter of the lunar surface. "We know from previous missions there is an increased abundance of hydrogen at the lunar poles. But we don't know how much or exactly where," Hardgrove said. "NASA has funded three different CubeSats to learn more: Lunar IceCube, Lunar FLASHLIGHT and LunaH-Map. They all look for water in different ways and provide different types of information." As LunaH-Map flies over the lunar South Pole at a very low altitude, it counts the energies of neutrons that have leaked out of the lunar surface. The energy distribution of the neutrons that hit the detectors tells us about the amount of hydrogen that's buried in the top meter of lunar soil. LunaH-Map will map the hydrogen content of the entire South Pole of the moon, including within permanently shadowed regions at high resolution. LunaH-Map will measure the bulk hydrogen content, up to a meter beneath the lunar surface, while the instruments on both Lunar IceCube and FLASHLIGHT will tell us about the very top few microns. LunaH-Map will create the highest-resolution maps of regional near-surface (top-meter) water-ice distribution across the entire South Pole of the moon. "Science is a human endeavor, and part of that is knowing each other and trusting each other. And when it comes to a NASA mission and taxpayer dollars to do exploration, you got to have the credentials. You have to be trusted, you need to have proven yourself, you need to show that you can make it happen and you won't fail. And we've got a history now where that's the case," said Linda Elkins-Tanton, director of ASU's School of Earth and Space Exploration. http://www.moondaily.com/reports/ASU_chosen_to_lead_lunar_CubeSat_mission_ 999.html [ANS thanks SpaceDaily.com for the above information] --------------------------------------------------------------------- AMSAT Events Information about AMSAT activities at other important events around the country.

Extreme DX FO29 Contact
by Dave Swanson 29 Aug '15

29 Aug '15

Satellite friends and colleagues, I'm happy to announce that at 1732UTC on August 27th, 2015, A QSO was made between myself, KG5CCI, and F4CQA on Satellite FO-29. This was not a scheduled contact, I simply answered Christophe's CQ call. I knew it was a good contact at the time, but as I was portable up on Arkansas' Shinnall Mountain, I did not have the resources available to calculate distances. After returning to my office I began to log the contacts I had made, and noticed the "general" distance between EM34 and JN17 was in excess of 7500km. About the same time I came to this realization, my email chirped with a message from Christophe, who had came to the same conclusion. After some quick exchanges, and verifying 10 digit locators, we have settled on an official distance of 7599.959km between my grid of EM34ST11TL and Christophe's grid of JN17EA22OT, using the http://no.nonsense.ee/qth/map.html website for calculations. To the best of our knowledge, referencing data found on Amsat-UK's website ( at http://amsat-uk.org/2015/05/06/uk-texas-extreme-dx-contact/ ) this breaks the previous distance records of 7537.799km between W5CBF and G4DOL, and the 7538.685km contact between K4FEG and DK1TB. I had my camera setup to record the pass as well, and you can view a raw clip of the contact here: https://youtu.be/orY0Re0IY30 If anyone has any questions about the contact, I'll be happy to answer them. Special thanks and a solid *GOOD-DX* to Christophe for the contact, and here's to many more. 73! -Dave, KG5CCI

N4HF - SO-50, 1659UTC (east coast) pass, Friday
by Philip Jenkins 29 Aug '15

29 Aug '15

Thanks to the 3 stations I worked today on SO-50. It was quite a different experience for me.... ...because I I was using a Kenwood D72A with headset/microphone and "manually controlled" Arrow antenna. I couldn't believe the audio quality difference this time.... ...because the last time I made SO-50 QSOs (March 2013, I think), I was just two different HTs, same Arrow antenna, and a speaker mic (but just for transmit). The receive radio was using the HT speaker, and hanging out of my pants' pocket :-) So, yeah, there's a lot I DIDN'T hear the last time I was on the bird. If anyone has a recording of todays' (Friday) pass, I'd appreciate hearing it. My intent today was to listen, to re-familiarize myself with the protocol, but the satellite was so loud (61 deg pass) and the audio so great, that when a lull occurred, I thought I'd try it anyway. So I didn't have a splitter going to an audio recorder (which I need to do soon, as I plan to (try to) demo SO-50 on loudspeaker at a special event - N4F/ham radio demo at a 10-day Fair in a couple of weeks; see Sept 2015 QST, pgs 65 and 94 for details). So my apologies if my QSOs weren't valid, if my protocol wasn't right; I was a bit nervous that the set-up worked as well as it did. I am AMAZED at the difference in using a headset! The only station I remember working is KI4RO, but don't know his gridsquare, so no valid QSO's on my end. So I'll be back on, but may be after the Fair ends around Sept 20 - and I plan to use the N4F call from the Fair; does anyone need EM85? :-) 73 de Philip N4HF (P.S. I have the equipment for linear sats - even HEOs - but let me get comfortable with SO-50 first, okay?)

Going to ARRL SW Division Convention next month?
by Patrick STODDARD (WD9EWK/VA7EWK) 28 Aug '15

28 Aug '15

Hi! The 2015 ARRL Southwest Division Convention is coming up, on 11-13 September in Torrance CA. I had asked this question on Twitter, and I'll widen the question to -BB readers. Is anyone planning to go to this convention? I'm thinking about heading out there for at least Saturday of that weekend (12 September). I won't have a booth there, but hope to meet up with other satellite operators out there, and maybe get a lunch or dinner. I will probably head back to Phoenix late that evening, since I am not able to spend all of that weekend in southern California. Please e-mail me directly - or send me a tweet, if you are on Twitter - if you're going to be there. Thanks in advance, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

1.2 GHz and 2.4 GHz Birds
by WILLIAMS MICHAEL 28 Aug '15

28 Aug '15

Bob, Sat Name: DTUsat-2, Beacon is 200mW, Object 40030, 2401.842 MHz. Signalsare very strong, and do not fade. Easily copied with a single helix. It's a good signal to test tracking on 2.4 GHz. Battery power has failed. Downlink only during ellipse using power from solar panels. DTUsat-2 appears at all locations either once or twice at about 11 AM local time and again about midnight. It is sun synchronous. The CW beacons can be every 30 seconds apart or one minute apart depending if the on board computer (OBC) is running. If the OBC is running, the first three bits following the CW I.D. will be "dash-dot-dot" or 100. If the three bits following the I.D is "dot-dot-dot" or 000, the OBC is powered but not running. When the OBC is running, CW beacons may be 1 minute apart with a tone sounding mid way between beacon intervals. Downlink may be a full CW beacon, partial CW beacon, a tone, or a missingsignal for that interval. The beacon CW coded message following the I.D ( OZ2DTU) is broken into five segmentswhich is STATUS, Radio Temp, Battery Temp, Battery Voltage, and Beacon Count. Beacon count, the last segment, is the "number of beacons since the last full system reboot". This number can be a "dot" which is zero up to a large number, for Example: "Dash Dash Dot Dot Dash" which is 25. To me, a good condition would be a Status of 100 with a Beacon Count 30.Doppler is 100 KHz over the entire pass. Current Keps and accurate computer clock is necessary for good tracking.I've been recording audio for about 3 months for DT University. It's a good signal to track. Google DTUsat-2. 73, Mike (K9QHO)

FS: Icom 451 UHF all mode radio
by John Geiger 27 Aug '15

27 Aug '15

I have for sale an Icom 451 all mode 70cm transceiver in very good condition. Looks really good for a radio of this age, and works fine also. I have been using it on the satellites with good results, and also in the UHF contest earlier this month. This will get you on both the linear and the FM satellites. I have had good luck with it so far on AO7, FO29, AO73, and SO50. It has a built in power supply, and does 10 watts out. Comes with a power cord and hand mic. The only "issue" with it is that the level to turn the VOX off and on is missing. It is in the VOX on position, but I just turned the VOX gain all the way down and it functions in PTT mode only. You can turn up the VOX gain if you want to use it in VOX mode. This transceiver covers the 430-440 mhz range of 70cm and doesn't have a tone encoder with it. One could be added, though. Here is a great chance to get on 70cm SSB/CW for not a lot of money. I am asking $160 for it plus shipping, and can take paypal/check/MO. Pickup is also possible in Lawton, OK or can meet close by for an in-person deal. 73 John AF5CC

Thanks John for the report. And thanks for reminding everyone to not attempt to make a contact before a scheduled ARISS contact. The ISS crew will only be listening for one specific callsign; that of the school or telebridge station. Once a contact is over, then it is fair game but just know they are probably back to work as soon as the contact is over. 73, Charlie AJ9N One of the ARISS mentors In a message dated 8/27/2015 1:33:34 P.M.

Had excellent reception (RS 59) horizon to horizon of the astronaut's side of the QSO between the ISS and Bunker Hill School, Indiana. I am located at Ivy Tech Community College in Batesville, IN (southeast corner of state, Grid EM79jg). Thank you very much to the astronauts, the folks in Bunker Hill School, and everyone who supports ARISS for making this possible. I did record it, but haven't checked my recording yet. Steve AI9IN

Hello amsat-bb, Have updated my CNCTRK site with information on the Raspberry Pi version of the system -- these data are new since the article was published in the May/June issue of the Journal. Am still planning to build a short run of APS units in Q4 (if our travel expenses son't break the bank, that is). Have fun and keep up the good work. Bob KI4SBL

Question about AMSAT BB
by Rick Walter 25 Aug '15

25 Aug '15

I know most of the AMSAT operation is done by volunteers. I also have wondered why some posts for satellite passes seem to be very close or even after the pass occurred. What is the average time between someone sending a post and when it actually appears on the BB? I sent a congratulatory message to the AMSAT team who produce the Journal as well as commenting on the content. I also mentioned getting my AMSAT Journal in the mail today to allow members to know it will be arriving soon. That post was sent at 2:46 PM EDT today.I BCC it to myself. It showed up in 5 seconds. Five hours later, I still do not see it listed on the AMSAT BB. I can see why some posts seem to be at the last minute before something happens that may be of interest to most of us. I'm not complaining, I just wonder if we need to post about 12 hours before something will actually happen. Thanks, Rick WB3CSY -- Sent from Rick's gmail account

Re: [amsat-bb] Question about AMSAT BB

I receive a daily digest, but other than checking the archives, is there any real-time or near-real-time way to see new bb messages? Rob, KA2CZU ------------------------------ Rick mentioned: >* I BCC it to myself. It showed up in 5 seconds. Five hours *>* later, I still do not see it listed on the AMSAT BB. * OK, EMike rang a bell :-) The list won't duplicate messages. The settings assumed you already received the message with your BCC. Try it without the BCC on your next message and you should see your messages shortly afterward. There is a Mailman setting for NODUP for all subscribers. The timing of the message actually appearing for you also depends on local settings. I use MS-Office Outlook for my primary e-mail. My Outlook settings are to check for new mail every 300 seconds (5 minutes). So a message actually arriving would be sometime in that 5 minute window depending on the time in the receive window when I sent the message. I use Gmail on my Android tablet and it usually receives messages sooner mostly because it is not likely waiting for the 5 minute receive window as in my Outlook settings. -- 73 de JoAnne K9JKMk9jkm at amsat.org <http://www.amsat.org/mailman/listinfo/amsat-bb> AMSAT VP User Services

PSAT PSK31 experimental software
by aflowers＠frontiernet.net 25 Aug '15

25 Aug '15

I put together an experimental program called DopplerPSK to compensate for the Doppler shift on the NO-84 (or NO-83) PSK31 uplink. In essence, its a PSK31 transmitter that is merged with an orbital propagator to cause your transmitted signal to drift exactly opposite to uplink Doppler effect. It does this in a phase-continuous correction so that you don't get errors due to discontinuous frequency adjustments from controlling a radio in discrete steps. In the case of PSAT and BricSat, it should cause your signal to stay at constant frequency in the satellite's uplink receiver, and thus you should get a stable frequency on the FM downlink as well. In turn, this means you should be able to use your favorite PSK31 demodulating software to copy the downlink since the frequency drift should stay well within the AFC tolerance of the software. Anyway, if there are any adventurous people who are set up to give this a go, I would be interested in seeing if it actually works. You can find a rough quick-start guide (which contains an explanation of how it works and what you need to get started) and the application package on the rather minimalist page here: http://www.frontiernet.net/~aflowers/dopplerpsk/dopplerpsk.html It's an experiment, so be prepared for disappointment. I am :-) Andy K0SM/2

Notification of passes
by Skyler Fennell 25 Aug '15

25 Aug '15

I have been very bad at making satellite contacts recently. The main reason is because they aren't at a specific time every day/week and I don't look for passes very often. When I do search for passes, I am busy during the pass or don't have enough time to prep for a pass in 10 minutes. In addition, I can only work FM, so there aren't many sats (like one) Has anybody ever found something to get notified when a pass is coming up (maybe in the next few hours or so) via text message or email or something else? Thanks, Skyler KD0WHB

It wont be a satellite road trip, but.....
by Tom Schuessler 25 Aug '15

25 Aug '15

Hello all, My wife and I will be taking 5 days to drive a rental truck from DFW, North Texas to Boston to move daughter and new husband's stuff to their new home and law school. The type of truck and the logistics of the trip will not really work with casual satellite ops. Maybe someday. However, I would love to make terrestrial QSOs with some of you folks along the way as I will have a dual bander and a small antenna mounted to the truck. Would love to say hi on local repeaters along the way. Here is the route and rough projected time table. Friday, August 28th, Afternoon-evening. Dallas, Texarkana, Little Rock. Saturday, August 29th, Little Rock, Memphis, Nashville, Elizabethtown, KY, Springfield KY. Sunday, August 30th, Springfield, KY, Lexington, KY, Cincinnati, Columbus, Cleveland. Monday, August 31st, Erie, Buffalo, Rochester, Syracuse, Schenectady. Tuesday, September 1st Albany Springfield, Boston. There might be some schedule flex, especially the last two days but that should be close. Contact me off list via my n5hyp(a)yahoo.com email with Callsign, city, repeater/s PL and other pertinent information. Perhaps we can exchange more than just a Grid Square. What a concept. 73 de N5HYP Tom Schuessler n5hyp(a)yahoo.com

SO-50 Yesterday at 1738Z
by James Lea - WX4TV 25 Aug '15

25 Aug '15

Did anyone record this pass? Hope worked a few stations from the beach in EL98 and there was an XE1 station that she worked at the end of the pass. The recording is covered up by someone on the beach coming up and asking what she was doing. I can’t make out the callsign. Thanks for everyone who bears with all of the kids as they learn how to be good operators! This pass was a great learning experience to explain how some people are lids and that it is illegal to key up your mic and whistle on the radio. The youngest wonders why someone would spend so much money and time to make a satellite station and then just try to jam people. She is very observant. 73, James - WX4TV
