upcoming DM02 grid expedition, including satellites
by Patrick STODDARD (WD9EWK/VA7EWK) 30 May '15

30 May '15

Hi! I received this e-mail on the mail reflector for my local DX club, announcing an expedition to the waters near San Clemente Island off southern California in grid DM02. I just tweeted the text of the e-mail, but will also post it here for those not on Twitter: ********** Along with Jim, K6ZH and Phil, N0KE, I am going on a boat trip to activate the FFMA #1 most needed grid - DM02. We are leaving from San Diego on Wednesday, June 10 aboard a 49' sailboat and will be on the air sometime late Wednesday, through sometime on Sunday, June 14, including most of the VHF contest. Unfortunately, we have to leave before the end of the contest because the Navy has scheduled exercises in the area on Monday. We will be active on 6 M, 2 M, probably 432, 1296 and satellites. Phil is responsible for everything other than 6 M. The easiest way to work us from AZ is via meteor scatter and we will be on that mode every morning and perhaps the evenings, unless there is Es. We understand there is no cell service (even though we will be close to San Clemente Island), so we will be in contact with pilot stations on 2 M FM in order to announce ourselves on Ping Jockey. If you don't use meteor scatter, it's not too late to learn! Otherwise you will have to listen for a very short (distance) Es opening or backscatter or some other nearly impossible propagation mode. We will be running about 500 W and a 3 el yagi (due to constraints from having to mount the antenna on a sailboat). We will use the call K6ZH. Watch for packet spots announcing our transmit frequency. Good luck. 73, Bud N7CW ********** I have e-mailed N7CW, asking for details on which satellites they are looking to work during this grid expedition. Since K1N was able to have success working FO-29 recently, maybe these guys can follow K1N's lead and make a bunch of satellite operators (along with the 6m ops and those on the other bands) very happy. Good luck, and 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

PSAT PSK31 telemetry
by Daniel Estévez 30 May '15

30 May '15

Hi everybody! More PSAT telemetry reports. Time 11:40 UTC, 30/5/2015, locator IN80do. Handheld arrow antenna and Funcube Pro + dongle. PSAT's signal was sometimes quite strong S5, despite the very bad urban receiving location with some buildings on the way of this low elevation pass. I also saw OE1KYA ending a QSO and then calling CQ, probably on terrestrial PSK31. I also saw some very short "blips" quickly raising in frequency (before FM demod). I have the SDR recording if anyone is interested. 73 de EA4GPZ. ------- 3A5`eacon B u 31 23 875 2jauŸr t W3ADO-óbeacon B 046 15 238G3 5»1utu9 +12ttQ eo eeo-Ox\ OiC © *on B 04 e e3 O21 251 +11 — W3ADO-5 beacon B 0h 0 18 30 826 249 +1I eo o WenADO-5 neacon B 051 6ó2öw 252 +15 eE HIA„ QŒ asie. e ykA ¡-ta ®acon eae h h h W3ADO-C beacon B 057 96 23 8ei2 250 +15 s o nW3ADO-5 beacon B 05ie 68 28 819 251 +1D eem t W3ADO-5 acon B 059booo0e1 81" 252 +18 n e # ooe 60 99 42 818 251 +19 iV W3ADO-5 beadon B 061 87 29 816 51 +19 o o i W3,DO-5 beacon B 062 9F 32 815 251 +20 eIa W3ADO-5 beacon¾ 063 71 23 815 25C +ƒ2eml¾ W3ADO- l beacon B 000 31 37 6 246 +16 nsVo W3ADO-5 beacon B 00G 75 35 813 252 +19 8s W3ADO-5 ceacon È002 34 41 81- 251 +20 snr WIADO-5 beacon B 0 ik 23 813 250 +n)U - u bO-5 beacon B 00o6 33 814 2 l1 +21 ´ W3A:O-5 beacon B 005 99 [1 811 251 +22 3o e W3ADO-5 beacon 006 99 4! 810 25Ë+22 v eEaÎol W3ADO-5 beacon B 0ae- Ž7 3( 830 24V l tieu

PSAT and BRICSat identified
by Nico Janssen 29 May '15

29 May '15

All, Using detailed doppler shift measurements, I find that PSAT is object 90720, ULTRASat 1, and BRICSat is object 90729, ULTRASat 10. Up-to-date TLE sets for these satellites can be found here: http://mstl.atl.calpoly.edu/~ops/ultrasat/ultrasat_jspoc.txt http://mstl.atl.calpoly.edu/~ops/keps/kepler.txt https://docs.google.com/document/d/1o48dswYcTHb-op9ygaKhrizrelMGV9pYcUm0SFm… This means that PSAT is actually object 40652, 2015-025B, and BRICSat is actually object 40661, 2015-025L, in the JSpOC catalog. But Space-Track does not publish TLE sets for these objects. Meanwhile, The Planetary Society suggests that the TLE set for object 90721, ULTRASat 2, gives the best match for LightSail. If that is correct, then LightSail is actually object 40653, 2015-025C, in the JSpOC catalog. 73, Nico PA0DLO

Re: [amsat-bb] PSAT- transmission sequence
by Tom Schuessler 28 May '15

28 May '15

The original email from David, reprinted below noted the "Stopping of the 435 downlink carrier and Bob WB4APR came back and said that the transponder is in an "Auto" mode which waits for a PSK signal and then turns on. My experience the other morning was that this was true, but as David says below, he was surprised by it turning off periodically. My surprise was that I was able to repeatedly turn it on when I started transmitting on 28.120 +1Khz, but before my CQ ended, the carier would quit. I repeatedly brought it up and also saw other not so copyable psk carriers on the waterfall but the transponder seemed not to stay on long enough to keep a full QSO going. I know for a fact because I duplicated at least three times turning on the FM carrier about 2-3 seconds after I started to uplink. I personally have yet in my several feeble efforts, been able to make a full QSO although I have been emailed by several to say that they did indeed hear me. This morning, 5-27 1207Z pass I was bad and had my RX radio to the wrong frequency but will give another shot at the 114xZ pass on 5-28 to see if I can make progress on making a Q.

9600 baud and IC-9100

Ok, so I'm hearing something I cannot verify. I have be trying to capture 9600 baud packets from BRICSat. Now I discover on the IC-9100 yahoo group someone is saying the IC-9100 does not handle 9600 baud packets over the USB port. I find this hard to believe but can any confirm or deny this claim? I have had issues catching anything with the IC-9100 and 9600 baud packets so was wondering if it was the setup or the radio. All feedback welcome please.. David, KK4QOE

PSAT Status (day 4)
by Robert Bruninga 27 May '15

27 May '15

PSAT PSK31 435.350 MHz FM downlink is full quieting with 6 bars using a decent UHF Yagi. But we have not seen any users other than those using the 28.120 PSK channel on HF normally. We welcome people to experiment with it. Everyone within the 28.120 to 28.123 MHz ten meter passband will be uplinked and heard on the 435.350 MHz downlink. The Naval Academy's PSAT seems healthy with plenty of power (we are keeping the APRS digipeater off to allow max power for PSK31). PSAT 's radio and packet system are a simple $250 APRS tracker http://www.byonics.com/mtt4b sent to space. The PSK31 transponder is a single 3.4" square circuit board made by Brno Universtiy in the Czech Republic. The CPU for controlling bulletins and timing is a simple Parallax Basic Stamp. PSAT is actually only about a 1U cubesat but in a 1.5U package since the flight was available and it gave us more power for our NON-SPACE solar cells. We are using standard silicon that are only half as efficient as multi-junction cells, but only cost 1% as much. PSAT has a single 21" VHF and 72" long HF whip. It has two UHF 6" orthogonal monopoles, all of very thin Nitinol wire. More details will eventually follow as the page will be updated over the coming weeks. http://aprs.org/psat.html * PSAT packet telemetry is OK, Digipeater will be off (secondary mission) * PSAT PSK31 transponder is ON with 28.120 MHz uplink! (primary mission) * WOD data fixed. Spin data now available. Right now it is at 3 RPM with +Z pointing 45 deg off Sun * Launch TLE elements (below) are still very good * http://PCSAT.APRS.ORG web page is now capturing PSAT telelmetry that users inject into the APRS-IS * BRICSAT telemetry has been heard but is cycling OFF due to low power * BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON) * USS Langley not heard FREQUENCIES: PSAT: 145.825 - 1200 baud AX.25 telemetry - digi off PSAT PSK31-5: 435.350 FM down, 28.120 SSB PK31 uplink - Brno University Xponder BRICsat: 437.975 - 9600 baud telemetry evry 20s BRICsat PSK31-6 - same as PSAT but PSK TLM on 375 Hz (PSAT on 315 Hz) USS Langley - 437.475 9600 baud telemetry <== CORRECTION ULTRASat3 <these are still tracking well> 1 99993U 15140.67013889 .00040043 00000-0 10235-2 0 00009 2 99993 055.0004 339.9238 0251027 182.3314 074.3075 15.12517086000014 Bob, WB4APR

Listen for LightSail - transmissions stopped
by JoAnne Maenpaa 27 May '15

27 May '15

Just read on-line at http://planet.ly/0gVop (Planetary Society) that the LightSail satellite stopped transmitting. The team is attempting a reboot. The telemetry data is sent on a downlink of 437.435 MHz, AX.25, 9600 bps FSK. Excerpt from their page ... As of late Friday afternoon, LightSail was continuing to operate normally. The spacecraft's ground stations at Cal Poly San Luis Obispo and Georgia Tech were receiving data on each pass. Power and temperature readings were trending stably, and the spacecraft was in good health. But inside the spacecraft's Linux-based flight software, a problem was brewing. Every 15 seconds, LightSail transmits a telemetry beacon packet. The software controlling the main system board writes corresponding information to a file called beacon.csv. If you're not familiar with CSV files, you can think of them as simplified spreadsheets-in fact, most can be opened with Microsoft Excel. As more beacons are transmitted, the file grows in size. When it reaches 32 megabytes-roughly the size of ten compressed music files-it can crash the flight system. The manufacturer of the avionics board corrected this glitch in later software revisions. But alas, LightSail's software version doesn't include the update. Late Friday, the LightSail team received a heads-up warning them of the vulnerability. A fix was quickly devised to prevent the spacecraft from crashing, and it was scheduled to be uploaded during the next ground station pass. But before that happened, LightSail's automated chirps fell silent. The last data packet received from the spacecraft was May 22 at 21:31 UTC (5:31 p.m. EDT). A LightSail map tracking application is at: http://sail.planetary.org/missioncontrol -- 73 de JoAnne K9JKM k9jkm(a)amsat.org AMSAT VP User Services

PSAT - BRICsat data?
by Robert Bruninga 27 May '15

27 May '15

PSAT – BRICsat: > Do you still want folks to send them in or are you getting want you want from the aprs.org site? We need people (who have time) to concentrate on capturing data from BRICsat on 437.975 9600 baud. PSAT seems stable and telemetry from volunteers is coming into the pcsat.aprs.org site OK. I am torn between using my UHF receiver for montoring PSAT PSK31, or concentrating on BRICsat.. But we need to figure out what is going on with BRICsat and try to rescue it. The PSK transponder on BRICsat is newer and better. I had been commanding PSK on PSAT to ON on every pass. But realized that would be masking the weak PSK31 beacons from BRICsat. SO I have stopped doing that. Now PSAT PSK is in auto – meaning it will come on if there is a user, but otherwise it will only come on once every 5m with a beacon. I will be going on travel for a week starting tonight, and so PSAT is on its own. The BRICsat command team will be returning to the Academy on Wed and may begin command efforts then. Hence the value of capturing any data to point them in the right direction. Bob, WB4APR

W5PFG/VE2 - FN35 & FN26
by Clayton Coleman 25 May '15

25 May '15

I'll be visiting Montreal, QC, Canada again in a couple of weeks. Several individuals have asked me about operating satellites from grid FN26. With those requests in mind, I will travel to FN26 for two orbits of FO-29. I do not know the specific passes at this time. There are a few others who are looking to have FN35 confirmed. I will post about those operations on Twitter @w5pfg shortly before and during the US Memorial Day Weekend Holiday. Please email me off-BB if you are interested in the FN26 operation. Thank you, 73 Clayton W5PFG

Re: [amsat-bb] PSAT and Bricsat FM PSK on same frequencies
by Tom Schuessler 25 May '15

25 May '15

Bob, Your explanation to my questions make much more sense now that I worked another pass of the satellites. Today the two were sufficiently separated that I could see one lagging behind and thus higher up in frequency because of Doppler shift. Your explanation on why the same frequencies for the two birds is quite nice. Also the frequency offset difference for the PSK beacons as well as the different IDs work as well. Bricsat was quite a bit weaker but that was probably because I was trying to track PSAT with my Arrow on a tripod. It was also a couple of Khz higher up. I also saw the difference in the two beacons so now I know how to tell which from which. I did try transmitting PSK31 USB on 28.120 + 1Khz or so and listening through HDSDR on 435.350. I heard faint signals of other PSK signals but believe they were just some other terrestrial QSOs and not directed through the satellite. They were slipping down the DIgipan waterfall as they would be without correction. I was not doing correction either on 28Mhz but I was hoping, even on playback of the HDSDR I/Q recording, to find me but I never did. Going to try a different software configuration next weekend to try and hear myself live. The best time to test PSK through these satellite transponders will be overnight passes when possible so as to avoid terrestrial stations from calling other terrestrials and confusing things. Will have to wait for times to shift for that. 73, Tom, N5HYP ____________________________ Message: 11 Date: Sun, 24 May 2015 10:56:55 -0400 From: Robert Bruninga <bruninga(a)usna.edu> To: amsat-bb(a)amsat.org Subject: Re: [amsat-bb] PSAT and Bricsat FM PSK on same frequencies Message-ID: <835f099c08a7be546571f9704a1ed498(a)mail.gmail.com> Content-Type: text/plain; charset=UTF-8 > ... how will this work with two FM satellites on the same frequency? The idea is to serve users no matter which spacecraft is in view. And to not have the users have to always change frequencies and track different objects. Imagine a camper in the field. Just point your beam towards AOS generally and set +5 KHz tuing and when a satellite comes into view, you can use it. Many things separate them: 1) Distance 2) Time 3) Doppler 4) Users antenna beamwidth When they are 5 minutes apart, the beam headings will be over 90 degrees apart (10 to 15 dB separation), the Doppler will be typically 10 KHz (10-15 dB separation) for a total of 20-30 dB or more to prevent capture effect. Since an orbit is 95 minutes long, and the satellites will drift, then 95% of the time, this condition of at least 5 minute separation, will be met. PSAT PSK (W3ADO-5) was built over 3 years ago and is hardwired to power up by default (maximum chance it will work despite spacecraft packet link or other failures) BRIC PSK (W3ADO-6) was built just last year and has independent control by Brno designers (can be off while sats are adjacent) It also powers up by default (again, for maximum availability in case of bus failure). So I think the choice pretty much meets the goals of maximum availability to users and as independent of spacecraft failures as we could make them. Hope that Helps. Bob, WB4aPR

Bob, Yes, it was. The time stamp is UT, which is 20:46 local time (dark now, almost winter). None of my steerable antennas are up yet, following a move into the city. I copied PSAT on a ground plane with a short length (5 metres maybe) of thin coax to a FT857D. PSAT must have a good signal.

Hi to the list, this morning i had a pass of the PSAT. I could hear it on 435.350 MHz, with the Funcube Dongle Pro Plus, but couldn't understand how to decode it. I've tried in USB and could hear a sound that could not understand it Also tried in FM but could hear just the background noise. Please anybody can tell me where to listen? Frequency and mode and also which program to use to decode it? Any help will be really appreciated. 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

PSAT and Bricsat FM PSK on same frequencies
by Tom schuessler 24 May '15

24 May '15

Okay so I am a bit confused about how this will work with two satellites both using FM modulation on the same frequency. FM has the capture ratio effect which basically means that if one signal is about twice as strong as the other that signal will capture the receiver and the other one may make a little background noise but won't be properly demodulates. If both of them are received at the same power level pretty much you just get noise a.k.a. SO-50 on a crowded day. So if these two satellites are transmitting simultaneously whichever one happens to be stronger at the moment will capture the receiver. Regardless of whether one of them has a audio frequency modulated on the carrier at 315 hertz while the other ones at 375 you're most likely going to not here both of them simultaneously Heard or displayed on a PSK waterfall. This may not be an issue in the future as the satellites drift apart from each other but right now as it seems to me they are pretty darn close so if they were both on they would be in the beam width of any directional antenna. Aside from the frequency of the PSK carrier itself as modulated on the FM, I would also have to assume that the call sign of the PSK data beacon is hopefully different. The PSK I decoded this morning had a beacon call sign of W3ADO-5. I would have to assume there is a different beacon call sign for both. In my reading I have not seen what the difference between the two would be. Looking forward to soon trying to test an uplink on 28.120 and see if I can hear myself. This looks like a good challenge. 73. Tom. N5HYP

AMSAT (and ARRL) at the IEEE International Microwave Symposium 2015 - report
by Patrick STODDARD (WD9EWK/VA7EWK) 24 May '15

24 May '15

Hi! On Thursday, 21 May 2015, I represented AMSAT and the ARRL at the IEEE International Microwave Symposium 2015 that was at the Phoenix Convention Center in downtown Phoenix. The ARRL had a booth in the symposium's University Pavilion in the exhibit hall, manned by Ward Silver N0AX during this week. Other hams helped Ward earlier in the week, and I was able to take a day off and spend Thursday at the booth. Along with Ward, Hermann Schumacher DF2DR, a professor from the University of Ulm in Germany, was also there with me. Although this was not an amateur radio event, there were lots of hams from around the world in the exhibit hall, and many students - high school and university students. The high school students were from different schools around the Phoenix area, and the university students were from universities in the USA and other countries. In addition to talking about the ARRL and amateur radio generally, Thursday was promoted at the ARRL booth as the satellite day, complete with on-air demonstrations in the afternoon. I brought my satellite equipment. I brought some AMSAT Getting Started with Amateur Satellites books, frequency guides, and Fox flyers to go with the ARRL literature. During the morning, I learned that Hermann had worked AO-6 in the 1970s, but had moved away from satellite operating. He enjoys SOTA operating on HF, and I think he's looking to give the satellites another try when he returns home. I had 3 demonstrations during the afternoon, starting with an SO-50 pass just after 1930 UTC (12.30pm local time). I was able to work Dave W0DHB in Colorado from outside the convention center, and then listen to the remainder of the pass. Although I only logged one QSO, being able to hear the pileups on SO-50 impressed the crowd. The FO-29 pass around 2124 UTC was the most fruitful pass of the day. Not only was it busy, I had my largest crowd of the 3 demonstrations. We walked across the street from the convention center to a pedestrian bridge over Washington Street, and had a good view of the sky from over the street. I used one FT-817ND and my Elk log periodic antenna, and this was the first time I had worked FO-29 half-duplex. I have heard others do this, and I remember reading an AMSAT Journal article in 2005 by Drew KO4MA detailing how to do this. It worked! I logged 6 QSOs with stations across the continental USA, and the crowd enjoyed hearing the locations of those stations. Thanks to K8YSE, AA5PK, N8HM, K0MDJ, KE4KOL, and N5AFV for calling and being a part of this demonstration! This was a great way to show off the coverage of our satellites, and how they could be used with a very simple station like my FT-817ND and Elk antenna. In the crowd for this FO-29 pass were a pair of university students from Turkey, who are working on CubeSats at their university. They were not familiar with amateur radio, and I have since e-mailed them information about amateur radio, amateur radio organizations in Turkey, and more information about AMSAT. I had taken a couple of pictures of them, and I also included the pictures with my e-mail. The later FO-29 pass, around 2310 UTC, yielded only one QSO, with Wyatt AC0RA. I was standing on the same pedestrian bridge outside the convention center, pointing my antenna to the west over downtown Phoenix on a 40-degree pass. For those keeping score, or logs, this symposium was in grid DM33xk. I have uploaded my QSOs to Logbook of the World, and a few have turned into QSLs. I will also send special QSL cards to everyone I worked during these satellite demonstrations. Hermann DF2DR assembled a short video that includes parts of the first two demonstrations I gave, and some photos from the symposium. You can see this video at: https://www.youtube.com/watch?v=EYzzgkPrmuw This symposium is a great example of a non-ham event where an amateur radio presence can reach many who have never heard of the hobby. Simply hanging a poster, or laying out flyers, with references to web sites would not have had the same effect as a booth with hams ready and able to talk about the hobby in general, and our satellites specifically. Thanks to Ward and Sean Kutzko KX9X at the ARRL for inviting me to be a part of the ARRL's booth at the symposium. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

Each year the American Radio Relay League (ARRL) sponsors Field Day as a "picnic, a campout, practice for emergencies, an informal contest and, most of all, FUN!" The event takes place during a 24-hour period on the fourth weekend of June. For 2015, the event takes place during a 27-hour period from 1800 UTC on Saturday June 27, through 2100 UTC on Sunday June 28, Those who set up prior to 1800 UTC on June 27 can operate only 24 hours. The Radio Amateur Satellite Corporation (AMSAT) promotes its own version of Field Day for operation via the amateur satellites, held concurrently with the ARRL event. If you are considering ONLY the FM voice satellite SO-50 for your AMSAT Field Day focus - don't - unless you are simply hoping to make one contact for the ARRL rules bonus points. The congestion on FM LEO satellites was so intense in prior years that we must continue to limit their use to one-QSO-per-FM-satellite. This includes the International Space Station. You will be allowed one QSO if the ISS is operating voice. You will also be allowed one digital QSO with the ISS or any other digital, non-store-and-forward, packet satellite (if operational). Many good contacts can be made on the linear transponder satellites including AO-73, FO-29, and AO-7. During Field Day the transponders come alive like 20 meters on a weekend. The transponders on these satellites will support multiple simultaneous SSB or CW contacts. The 2015 AMSAT Field Day event is open to all Amateur Radio operators. Amateurs are to use the exchange as specified in ARRL rules for Field Day. The AMSAT competition is to encourage the use of all amateur satellites, both analog and digital.

President Barack Obama appointed Newman last October, and the US Senate confirmed her appointment on April 27. The swearing-in took place on May 15 in her MIT office in Cambridge. Newman is Apollo Professor of Astronautics and Engineering Systems and the director of the Technology and Policy Program at MIT. She started her official duties as NASA's new deputy administrator on May 18 at the agency's headquarters in Washington, DC. "I'm very excited to be at NASA," said Newman. "I'm looking forward to being a part of the agency's work to expand humanity's reach into space, advance our journey to Mars and strengthen America's leadership here at home." NASA Administrator Charles Bolden, ex-KE4IQB, said he's long admired Newman. "Her talents and skills as an educator and technological innovator will bring a new energy to our NASA leadership team, and I'm ecstatic to have her on board," he said. Newman had been on the MIT faculty since 1993. Her research has included modeling human performance in low and microgravity conditions, examining the dynamics and control of astronaut motion, and the development of assisted walking devices for the physically handicapped. Possibly her most prominent project has been the development of the BioSuit, a skintight spacesuit that would give astronauts unprecedented comfort and freedom in exploration of planetary surfaces and extra-vehicular activity.

At 22:30 GMT on May 21, 2015 Bob Bruninga WB4APR posted the following update on the AMSAT Bulletin Board about the three USNA CubeSats PSAT, BRICSAT and USS Langley along with a guide on how to use the PSK31 transponder. We now have heard 4 of 5 transmitters from our 3 spacecraft all still in a close cluster: * PSAT packet is OK but WOD not working (no digipeating for users yet) * PSAT PSK31 downlink is ok [remember, it is FM!] * BRICSAT telemetry has been heard but is cycling OFF due to low power * BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON) * USS Langley not heard PSAT CPU shows the 4 day-fail-safe backup reset circuit is not counting down, so we have lost this (1 of 3) fail safe backup RESET capabilities. Bad line of code already found. But cannot change it. PSAT is not properly reporting WOD data and S#… STATUS packets are being bundled until 255 byte packet length is reached and then it all comes down at once. Noone has captured any of these long packets. Please try with PASSALL ON so that you can receive partial packets. Awaiting permission from BRNO University to authorize HF user uplinks on PSAT PSK31. BRICSAT PSK31 transponder is on identical frequencies as PSAT’s. You can tell them apart because one has PSK Telemetry on 315 Hz and the other is on 365 Hz. Both on the UHF FM downlink 435.350 MHz We’d LOVE to hear from USS Langley, and we’d love to capture one of those long WOD packets from PSAT. Our ground station is only getting a few packets compared to some submissions from others. Keep it up. SUMMARY: 145.825 1.5U cubesat – PSAT 1200 baud AX.25 435.350 same cubesat – PSAT PSK31 FM – Brno University transponder 437.975 1.5U cubesat – BRICsat 9600 baud 435.350 same cubesat – BRICsat PSK31 FM – Brno University transponder 437.975 3.0U cubesat – USS Langley 9600 bd ULTRASat3 1 99993U 15140.67013889 .00040043 00000-0 10235-2 0 00009 2 99993 055.0004 339.9238 0251027 182.3314 074.3075 15.12517086000014 Receiving the PSAT PSK31 FM downlink Receiving the PSAT (and BRICsat) 435.350 MHz FM downlink is as simple as placing your PSK31 laptop microphone next to the speaker on your FM satellite UHF receiver and just watching the waterfall. What you see is exactly what everyone else sees (its FM). There is no Doppler added to the tones due to your station’s position relative to the satellite. But you DO have to retune your FM radio at least 3 times during the pass (+5 kHz, 0, -5 kHz) to stay in the FM passband. [Note: UK users should remember to selected the wide FM (5 kHz deviation/25 kHz channel spacing) setting on their rigs] User uplinks, however, will shift in the waterfall according to each user’s position relative to the satellite. The shift can be as low as 1 Hz per second to as high as 6 Hz per second. This is because the uplink is on 10 meters where the Doppler rate is only 1/15th of what it would be on UHF. The TELEMETRY channel at 315 Hz (PSAT) or 375 Hz (BRICsat) is FIXED with no Doppler since it is generated onboard into the FM downlink WHAT TO DO: 1) We will need PSK31 authors to open the PSK31 frequency tracking to accommodate more than 1 Hz per second Doppler tracking. Current implementations can do 1 Hz/s but completely fail at 3 Hz/s. 2 Hz/s might work a little… 2) Until then, ANY uplink user that is in line with a direct overhead pass will have minimum Doppler at the start and end of his pass (1 Hz/sec) when the satellite is going right at him and directly away from him. (Though it will be MAX (6 Hz/sec) when it passes over her/his station). 3) Just turn on MULTI CHANNEL window and let the PSK31 decode everyone.The ones with the least Doppler at any instant may be decoded for a while! USERS can transmit later when BRNO University says it has completed its tests. Brno provided the transponders for use in the PSAT and BRICsat satellites. So start preparing your station to TX PSK31 on 10 meters SSB and to receive the audio from an FM UHF rig on 435.350 +/- 5 kHz steps of Doppler. DOWNLINK Limitations: The UHF downlink signal is only 300 mW and so a UHF beam is needed on the downlink. UPLINK RESTRICTIONS: *NOTHING MORE THAN* a Vertical 1/4 wave or Dipole is authorized on the 10m uplink and no more than 25 Watts (for now). Remember a 1/4 wave vertical is the ideal antenna because it maximizes the signal at lower angles and tapers the signal as the satellite gets closer. This keeps user uplinks about the same during a pass. Strong stations just drive down the AGC and ruin it for everyone. Use minimum power!! Remember, this is crossband FULL DUPLEX so you can see yourself in the downlink just like everyone else can see you. Act accordingly. And of course DO NOT TRANSMIT if you cannot see the waterfall … Duh! Enjoy!

NEVERMIND! End of SUBJECT Thread... The original TLE is good! ***I must have made a typo entering TLE into Instantrack and had to retard time by now 8.5 minutes to get it to work. But with same TLE in SATPC32 (copy pasted instead of manually enered) then predictions ARE CORRECT. So FORGET this THREAD. TLE's from launch day *are* OK. Back under my rock. Besides PSAT's PSK ID's as W3ADO-5 on 315 Hz and BRICsat's as W3ADO-6 on 375 Hz. Should be flying very very close to each other. Separation spring between them was only 1mm long.

FW: PSAT Telemetry
by Tom Schuessler 23 May '15

23 May '15

-----Original Message----- From: Tom Schuessler [mailto:[email protected]] Sent: Saturday, May 23, 2015 11:37 AM To: 'bruninga(a)usna.edu' Subject: FW: PSAT Telemetry Bob, Got a chance to listen to the PSAT PSK beacon this morning on what was to be the 1246Z pass. I used HDSDR controlled by SATPC32 to get the passband. HDSDR ot Digipan through a virtual audio cable to decode. The Doppler was off which makes sense with the Keps that are off from what was posted. Saw some initial short transmissions with gaps in between and then a rather long run of transmissions. I never saw any other PSK31 activity besides the data beacon. Someday soon I will give transmissions a shot. Attached is a file with the data I decoded this morning. Approximate time stamp of first beacon is at the head of the file. I know you have made some reference in BB emails as to what some of the parameters generally mean. Will there be more details or a telemetry decoder soon? I love the PSK transponder idea the University has created and look forward to giving it a try. 73, Tom, N5HYP

UT1FG/MM update
by John Papay 23 May '15

23 May '15

Yuri has left Norfolk and is on his way to Mariel Cuba. You may have seen him at anchor out in the bay after he left the berth. A fuel barge was next to him filling up his tanks! Yuri has sent mail to the following stations: KD8CAO W5PFG W5CBF N5UXT KJ4MCZ KO4MA WA4NVM K4FEG N2PPL K9HF K8II W1PA WN9Q. If you don't receive something in two weeks, please let me know. As you can imagine, it is no easy job to confirm so many contacts with so many different stations. He does what he can considering the time he can spare. It is a never ending job for him. You may have heard that WX4TV and his family were able to visit the ship yesterday just before it sailed. Yuri was very busy with his agents and last minute paperwork but one of the crew gave them a tour of the ship. I expect that Jim will be sharing some photos/video of that visit. We are very fortunate to have someone like Yuri take an interest in operating the satellites in hundreds of water grids. It's fun to make all of those contacts, but it is also a lot of work to get confirmations out when you are not at home. Yuri is an amazing operator and ambassador for ham radio. His callsign is recognized by vhf'ers around the world. Good luck to everyone trying to work him. The route down to Cuba should be new for many operators. 73, John K8YSE

PSAT PSK31 transponder
by David W0DHB 22 May '15

22 May '15

This last pass of PSAT I was able to successfully decode myself and others (KI4ENY, K0RJV) using DM780 and MixW. Couple of observations: 1) MixW is the only PSK31 program I could find which can do full duplex, 2 running copies of DM780 and fldigi work also. 2) Using SATPC32 Doppler Shifting Uplnk and Downlink, set to 10 Hz interval with "times 10" selected kept the downlink signals fairly stable frequency wise. 3) Probably due to TLE's, Uplink signal downlinks about 400 Hz High. A recording of the pass can be found here: https://www.dropbox.com/s/825x9wxwteh2273/FM%20435.358633MHz%20%5B12k%5D%205 -22-2015%2021%2020%2004.wav?dl=0 55 MB Dave W0DHB

PSAT PSK31 Telemetry over Washington, DC 2130Z
by Paul Stoetzer 22 May '15

22 May '15

Good evening, Nice strong signals from PSAT over southwest Washington, DC (FM18lv) around 2130Z. I decoded several frames of telemetry from the beacon and saw a couple of PSK31 signals in the passband, but from what I could decode, they appear to have been terrestrial QSOs in progress. I did not see the BRICSAT beacon at all. I was not setup to transmit on this pass. Maybe tomorrow. Thanks to the U. S. Naval Academy, WB4APR, and Brno University for something different to try out. Hopefully I'll be able to make a QSO soon! The decoded telemetry is below. Receive setup was a Yaesu FT-817, Arrow II, and HSM LNAA432 preamp. I had the levels screwed up when live, so this is decoded off my recording with fldigi.

Re: [amsat-bb] Receiving PSAT PSK31 FM downlink (Users Welcome)
by Robert Bruninga 22 May '15

22 May '15

The Brno University builders of the PSK31 transponder on PSAT have now authorized user uplinks on 28.120 MHz PSK31 SSB. Downlink FM on 435.350 +/- 5 KHz doppler. Here is the announcement from Brno University: "We can uplink open to all users. Please, do it." - Mirek OK2AQ Do NOT operate if PSAT telemetry is below 7.20 volts. Cease operations. The voltage parameter is the second data field. For example, this morning the telemetry packet is showing 8.99 volts in the second data field: T#658,899,072,583,875,854,00011100. The third field is current (here showing 72 mA so Transponder is off. When PSK is on, then current goes to over 300 mA) We'd like to get some packets in the DARK showing battery voltage while not charging? Enjoy Bob Bruninga, WB4APR -----Original Message----- Sent: Thursday, May 21, 2015 7:20 PM Subject: Receiving PSAT PSK31 FM downlink Receiving the PSAT (and BRICsat) 435.350 MHz FM downlink is as simple as placing your PSK31 laptop microphone next to the speaker on your FM satellite UHF receiver and just watching the waterfall. What you see is exactly what everyone else sees (its FM). There is no Doppler added to the tones due to your station's position relative to the satellite. But you DO have to retune your FM radio at least 3 times during the pass (+5 KHz, 0, -5 KHz) to stay in the FM passband. User uplinks, however, will shift in the waterfall according to each user's position relative to the satellite. The shift can be as low as 1 Hz per second to as high as 6 Hz per second. This is because the uplink is on 10 meters where the Doppler rate is only 1/15th of what it would be on UHF. The TELEMETRY channel at 315 Hz (PSAT) or 375 Hz (BRICsat) is FIXED with no Doppler since it is generated onboard into the FM downlink WHAT TO DO: 1) We will need PSK31 authors to open the PSK31 frequency tracking to accommodate more than 1 Hz per second Doppler tracking. Current implementations can do 1 Hz/s but completely fail at 3 Hz/s. 2 Hz/s might work a little... 2) Until then, ANY uplink user that is in line with a direct overhead pass will have minimum Doppler at the start and end of his pass (1 Hz/sec) when the satellite is going right at him and directly away from him. (Though it will be MAX (6Hz/sec) when it passes over his station). 3) Just turn on MULTI CHANNEL window and let the PSK31 decode everyone. The ones with the least Doppler at any instant may be decoded for a while! USERS can transmit later when BRNO University says it has completed its tests. Brno provided the transponders for use in the PSAT and BRICsat satellites. So start preparing your station to TX PSK31 on 10 meters SSB and to receive the audio from an FM UHF rig on 435.350 +/- 5 KHz steps of Doppler. DOWNLINK Limitations: The UHF downlink signal is only 300 mW and so a UHF beam is needed on the downlink. UPLINK RESTRICTIONS: *NOTHING MORE THAN* a Vertical 1/4 wave or Dipole is authorized on the 10m uplink and no more than 25 Watts (for now). Remember a 1/4 wave vertical is the ideal antenna because it maximizes the signal at lower angles and tapers the signal as the satellite gets closer. This keeps user uplinks about the same during a pass. Strong stations just drive down the AGC and ruin it for everyone. Use minimum power!! Remember, this is crossband FULL DUPLEX so you can see yourself in the downlink just like everyone else can see you. Act accordingly. And of course DO NOT TRANSMIT if you cannot see the waterfall ... Duh! Enjoy! Bob, WB4APR

PSK-31 Author ideas
by Robert Bruninga 22 May '15

22 May '15

PSK31 authors: Peter Martinez G3PLX, original author of PSK31 reminds me that the ideal Satellite PSK31 decoder would take advantage of the full-duplex links and simply have the user click on his own signal in the downlink and then his own softwar would AFC his uplink based on his downlink. Thus everyone remains locked in place in the waterfall! Bob, WB4APR -----Original Message----- From: Peter Martinez [mailto:[email protected]] Subject: Re: Receiving PSAT PSK31 FM downlink (Users Welcome) Bob: In addition (or instead of?) urging PSK31 software authors to widen-out the AFC on receive, it would be far better in the long term to get these authors to include the ability to AFC the users uplink transmit frequency to null the Doppler drift on the user's reception of his own signal in the downlink baseband. This will eliminate the risk of multiple uplink signals from different directions drifting across each other, and opens up the possibilities for many new techniques such as unattended reception (in the same way that unattended reception of the tepemetry is possble now). ModernPSK31 programs should have no difficulty letting the user spot his own signal in the waterfall with a special mouse-click and applying the AFC to the transmit audio tone while the program is running full duplex. The multiple-receive features on these moderm programs can then be used to work full duplex QSOs, with the user leaving his transmit signal keyed-on during the whole pass. Similarly, modern PSK31 programs should be able to measure the mean received SNR of one's-own downlink signal and adjust the transmit tone amplitude to keep the SNR to a reasonable level, say 14dB. I have these two features working on my own software today but this program is not sufficiently well written that I am prepared to make it available on a wide distribution, although program developers are welcome to have a copy to play with, including the source code. 73 Peter ----- Original Message ----- From: "Robert Bruninga" <bruninga(a)usna.edu> To: "Miroslav Kasal" <kasal(a)feec.vutbr.cz>; "Peter Martinez" <peter.martinez(a)btinternet.com>; "Urbanec Tomáš" <urbanec(a)feec.vutbr.cz>; "Petr Vagner" <petrv81(a)gmail.com> Cc: <bruninga(a)usna.edu> Sent: Friday, May 22, 2015 3:55 PM Subject: FW: Receiving PSAT PSK31 FM downlink (Users Welcome) > PSK31 team.

It has worked flawlessly for many years on my laptops running XP and Windows 7. Starting this week, I get an error on all three computers. The program downloads the master lists fine but when I click the button to parse them out and check for errors, I immediately get "Unhandled exception has occurred in your application Spacetrak .... Index and length must refer to a location within the string parameter name length. I am using version 3.0.1.3 (2013Jul17) and even upgraded on one computer to version 3.0.1.5 (2014 Dec18).

We now have heard 4 of 5 transmitters from our 3 spacecraft all still in a close cluster: * PSAT packet is OK but WOD not working (no digipeating for users yet) * PSAT PSK31 downlink is ok [remember, it is FM!] * BRICSAT telemetry has been heard but is cycling OFF due to low power * BRICSAT PSK31 downlink (also FM) has also been heard barely (when ON) * USS Langley not heard PSAT CPU shows the 4 day-fail-safe backup reset circuit is not counting down, so we have lost this (1 of 3) fail safe backup RESET capabilities. Bad line of code already found. But cannot change it. PSAT is not properly reporting WOD data and S#...

Receiving PSAT PSK31 FM downlink
by Robert Bruninga 21 May '15

21 May '15

Receiving the PSAT (and BRICsat) 435.350 MHz FM downlink is as simple as placing your PSK31 laptop microphone next to the speaker on your FM satellite UHF receiver and just watching the waterfall. What you see is exactly what everyone else sees (its FM). There is no Doppler added to the tones due to your station's position relative to the satellite. But you DO have to retune your FM radio at least 3 times during the pass (+5 KHz, 0, -5 KHz) to stay in the FM passband. User uplinks, however, will shift in the waterfall according to each user's position relative to the satellite. The shift can be as low as 1 Hz per second to as high as 6 Hz per second. This is because the uplink is on 10 meters where the Doppler rate is only 1/15th of what it would be on UHF. The TELEMETRY channel at 315 Hz (PSAT) or 375 Hz (BRICsat) is FIXED with no Doppler since it is generated onboard into the FM downlink WHAT TO DO: 1) We will need PSK31 authors to open the PSK31 frequency tracking to accommodate more than 1 Hz per second Doppler tracking. Current implementations can do 1 Hz/s but completely fail at 3 Hz/s. 2 Hz/s might work a little... 2) Until then, ANY uplink user that is in line with a direct overhead pass will have minimum Doppler at the start and end of his pass (1 Hz/sec) when the satellite is going right at him and directly away from him. (Though it will be MAX (6Hz/sec) when it passes over his station). 3) Just turn on MULTI CHANNEL window and let the PSK31 decode everyone. The ones with the least Doppler at any instant may be decoded for a while! USERS can transmit later when BRNO University says it has completed its tests. Brno provided the transponders for use in the PSAT and BRICsat satellites. So start preparing your station to TX PSK31 on 10 meters SSB and to receive the audio from an FM UHF rig on 435.350 +/- 5 KHz steps of Doppler. DOWNLINK Limitations: The UHF downlink signal is only 300 mW and so a UHF beam is needed on the downlink. UPLINK RESTRICTIONS: *NOTHING MORE THAN* a Vertical 1/4 wave or Dipole is authorized on the 10m uplink and no more than 25 Watts (for now). Remember a 1/4 wave vertical is the ideal antenna because it maximizes the signal at lower angles and tapers the signal as the satellite gets closer. This keeps user uplinks about the same during a pass. Strong stations just drive down the AGC and ruin it for everyone. Use minimum power!! Remember, this is crossband FULL DUPLEX so you can see yourself in the downlink just like everyone else can see you. Act accordingly. And of course DO NOT TRANSMIT if you cannot see the waterfall ... Duh! Enjoy! Bob, WB4APR

PCSAT-1 - Report
by GW1FKY＠aol.com 21 May '15

21 May '15

Hi, I was monitoring the Funcube-1 Dashboard Data this morning (Thursday 21st May) and after its pass I tuned around 145.825 Mhz. I appear to have heard CW from PSAT-1 at a late stage of a pass before it got to low. The frequency was around 145.824 Mhz and the time 1142 gmt. Sorry I perhaps missed an opportunity to monitor and give a full report. Please note also that UO-11 is "off" at the moment but I was getting data bursts from NO-44 during an earlier pass.

DUCHIFAT1 - first 'Compressed APRS' tests
by Herzliya Science Center 20 May '15

20 May '15

Hi all, DUCHIFAT1, the Israeli high school students 1U Cubesat is ready for first public tests. People with the ability to send Compressed APRS location packets are invited to join the tests. The satellite will collect these packets worldwide along its flight at 620km high orbit, and will downlink them from time to time over our ground station in Herzliya/Israel. Participants are kindly requested to register in advance in order to get their packet identified on the map. The packets successfully received will be displayed on a map in our Internet site and QSL cards will be sent via Bureau to the stations registered and recognized. (unfortunately, there is no way we can recognize packets from unregistered stations because the packet is limited to 14 character at the satellite, so we assign two unique characters to every registered station to enable us to identify them). Registration can be done at www.h-space-lab.org Also available in that site are operational information about the satellite, and the following documents: *Configuring TT4 Explanation.doc* - how to use the Byonics TinyTrak4 for generating Compressed APRS packets *Terms Of Use.doc* - terms and techniques for making the best use of the satellite There is also Ground station software available for download, written by our students around ISIS space Demodulator software. We hope many people will find it interesting and enjoyable, good luck! 73 from the Herzliya Science Center students and teachers

PSAT Telemetry
by Robert Bruninga 20 May '15

20 May '15

When PSAT is in SAFE mode, the callsign is PSAT-1 and TOCALL is APOFF. The decode of PSAT-1 telemetry is as follows: T#038,886,079,625,744,788,00011100 038 Means 38th (1 minute) packet. 886 means 8.86 volts (8.4V is full charge) 079 means 79 mA system current 625 is +Z temp 744 is -Z temp 788 is Battery temp Decreasing Temperature counts mean warmer temps. Calibration for +Z/-Z are same, but for Battery is different. T#041,875,075,619,718,785,00011100 3 minutes later +Z/-Z are still warming and at greater rate than internal battery. For +/- Z, Count of 600 is about 30C. Count of 800 is about 0C. For Battery, count 700 is about 30C. Count of 840 is about 0C. Again, this second count-down to BURN is a second attempt to burn in case the first one failed. But since we hear it, then the antenna burn was successful and we need no more burn attempts.

Did not listen for PSK31 yet on 435.350 (both other UHF’s were listening for other spacecraft). T#039 and T#040 were the two telemetry’s received. So spacecraft had been operational for 39 minutes. That places activation at about 13:57 EDT over New Zealand (about 2 hours before sunup there). Bob, Wb4APR
