HI John, Yes, you were the first. As listed in order in the previous email. That pass was mostly through the villa for the first half. Apparently the uplink was getting through it but the downlink was blocked. Next pass will be in the clear once it clears the volcano after about 4 minutes or so. The only stations worked were listed in the previous email. Sorry, we are are not going to take time to pass the grid. Just a waste of time in my view. We are in FK86vs, as posted on qrz.com / vp2mkv. We are pleased to give out Montserrat to as many unique calls as possible. We should be able to be on passes as listed on the qrz.com page for at least the next 4 days. We got a late start because our crate of antennas, which we paid to have sent directly to the villa, had to be ransomed out of customs, which took two days and hours and hours of time, two inches of documents, a lot of explaining, along with money. But it's all good now with 6 HF antennas up and a big 6 meter beam. Made a few 6 meter contacts yesterday, nothing today. Our 6 meter beacon board turned out not to be compatible with the keyer so we are not beaconing on 50.102 as previously advertised, but will be listening mostly on 50.125. Hoping for Europe tomorrow morning. HF has been noisy and weak signals until just the past few hours. Jim eOn 6/12/2015 1:26 PM, John Papay wrote: > Tim, > Thanks for getting on FO-29 from VP2M.

VP2MKV first contacts
by Jim White 12 Jun '15

12 Jun '15

First contacts a few minutes ago from VP2MKV. K8YSE AA9LC K3SZH KO4MA KB1PVH Heard KB1RVT at the end of the pass but did not complete. Please do not tune your uplink. Just use 145.925 as your uplink and we will tune for you. When stations slide around it makes it much harder to catch calls and wastes time. We will be on the next pass, which is much better for us with less volcano blockage. See QRZ.COM VP2MKV for details of the operation. Jim WD0E operating W0ETT as the human antenna rotor

VB Audio Cable & Mixers
by Les Rayburn 12 Jun '15

12 Jun '15

With many of us moving towards SDR based receivers, RDS decoders and loggers, etc. there is increased need to route signals using Virtual Audio Cables. Wanted to make everyone aware of a free alternative to the more popular VAC application. VB Cable is "donation-ware" and works great. Their audio mixer is also a wonderful and visual GUI that makes complicated routing simpler for many since you can easily visualize the signal path. Give them a try! -- 73, Les Rayburn, N1LF Maylene, AL EM63 Member NRC, IRCA, & Medium Wave DX Circle Former CPC Chairman for NRC/IRCA ============================== FM DX Sony XDR-F1HD, Sangean HDT-1, Elad FDM-S2, AirSpy.

APRS Satellite in Los Alamitos needs voluntter?
by Robert Bruninga 11 Jun '15

11 Jun '15

Is there any HAM operator near Los Alamitos, Ca that can help test the next APRS Satellite being integrated there? All we need is someone to configure a radio to RX on 144.39 on a good outside antenna, and another radio to TX the audio on 145.825 (low power into a dummy load) near the spacecraft. This will provide some “traffic” on the 144.825 channel (low power) to make sure the spacecraft does not do anything weird when it begins to see user packets. I envision the volunteer to make a trip to the plant to set up this radio, and then come get it later after testing is complete. It will take two 2m radios and GOOD audio response so that packets do not degrade as they are retransmitted on 145.825. The trick will be giving it a high enough receive antenna so that it can hear plenty of source packets, and then to have the other TX on low power and into a dummy load placed near the spacecraft so that the 145.825 repeated packets don’t QRM the satellite channel outside the building. Anyway, it is a challenge, but critical to making sure this APRS satellite is flight ready? Anyone feel up to contributing some time and effort to the next APRS satellite? Bob, WB4aPR

>From Great Bridge High School W4GBH K4AMG Club sponsored amateur radio activities and OSCAR Communications. School class room hours did not align well. We did make several contacts on SO 50 and listened to data from the ISS and using Dash Board copied many frames from AO 73. Our next scheduled OSCAR event will be Field Day. Maybe next year we will find more passes as we will be working 2 electronics classes, and also possibly set up at the Chesapeake Center for Science and Technology - W4FOS. In October we will sponsor the STEM activities at the Heritage and Waterway festival in Chesapeake.

Bill Morine, N2COP, will be the guest on the W5KUB.com video broadcast this Tuesday evening, June 9th at 8pm Central (0100utc Wednesday). Those who chase grids will recognize the callsign as he has been active from FM13, a rare east coast grid, over the past 6 months or so. He operates from Bald Head Island and was the one who gave Doug, KD8CAO, his last grid for the Gridmaster's Award for working all 488 Continental USA grids on Satellite. Hopefully he will be asked about his experience with operating satellites, especially from FM13. More info on W5KUB.com. 73, John K8YSE

PSAT digipeater reception 2015-06-08 1430 UTC
by John Brier 08 Jun '15

08 Jun '15

Hi all, I received PSAT for the first time today. I had just done an SO-50 pass and saw that PSAT would be in range in about 30 minutes so I stuck around to try and receive it. It seemed surprisingly strong considering it is supposed to only be putting out 350 mw. I recorded audio of the pass and just now tried to decode it with UZ7HO's Soundmodem for Windows, which I have used to decode the ISS digipeater. Unfortunately, I am only able to decode two packets out of the numerous transmissions which, to me, seem strong enough to decode. This is a problem I've had with the ISS as well but it never seemed this bad. Are there some special settings I need to change in Soundmodem to decode the packets from PSAT? For example, I only see APRS packets, no satellite beacon data, shouldn't I see that too?

08 Jun '15

Hello all, I tryed out the pass on APRS about 12:50 UTC today. Very very strong satellite 57! Could not digepeat a packet for some reason. I think i was a little confused about the paths, what are the paths for to and via? Im using UISS. Got many frames of Telemetry this pass as well! Also bob you should at PSAT to oscar.dcarr for recepetion reports. I noticed very few people got digpeated... Also bob the frames that have all the numbers in them, what do they mean, are the just noisy tlm frames? Also for all the people out that wanted to know what their frame of telemetry means here you go: PSAT Beacon specification: CALL beacon MODE NOF DET AGC VC IC TMP Where: CALLidentification of the beacon (callsign)beaconkeyword indicating beginning of dataMODEA or B (A – transmitter always on, B – transmitter turns on, if BPSK31 signal is present)NOFnumber of frame (0 … 999)DETpercentage of BPSK31 detection (0 … 99%)AGCpercentage of AGC operation (0 … 99%)VCsupply voltage (10 mVolts)ICpower amplifier current (mAmps)TMPtemperature of PA transistor (deg C) The AGC measured voltage is highly nonlinearly dependent on the input signal, morover the limiting values of measurement vary with temperature of the chip and its supply voltage. Indicative only conversion equation was computed as from 50Ohm generator to input of receiver Pin = 0.472xAGC-113.5 [dBm, %] Example: W3ADO-5 beacon B 044 03 24 540 198 +28 It means mode B active, frame number 044, BPSK31 03 %, AGC acting 24%, supply voltage 5.40V, PA current 198mA ant temperature of the PA transistor of +28°C.

It woiuld be a great science project for kids to plot the doppper and see if they can figure out the position of a station! When authors start upgrading PSK31 programs so that they are fdull duplex and can AFC their own uplink, then none of the satellite user signals will slew, but since we chose the same uplink as normal terrestrial PSK31 users, those signals can plot a nice Doppler curve. The only problem there is that they turn their transmitters on and off, but usually stay on the same 10m frequency, so that means although their signals are disjoint, their emissions should all be on their theoretical Doppler curve and therefore can be located. Actually, on just one pass all you can get is a line of position relative to the satelites track, But on two passes, then you can have two lines of position and where they intersect is the stations position. Good luck! Maybe someone has the time to search for a good reference for the technique. Bob, Wb4APR US Naval Academy

Looking for someone who is Intelligent, Ambitious, Not Too Old, and Dedicated.
by Thomas Doyle 07 Jun '15

Hi, The fact that you opened this message means you are all of the things mentioned in the subject line and probably even good looking. This fellow has come up with what I believe is the first really good portable rotor controller (even better than mine !). He is planning on releasing the plans to the public. Fabrication was done with a 3D printer. It is a work of art. It is not some pie in the sky all talk and no action thing we are all used to hearing about. http://www.mobypicture.com/user/MeltdownCore/view/18165109 Here is a clip from a recent email he sent to me. There are many people out there that have 3d printers in these days. When i >> designed the rotor i wanted to make sure that most parts come out the 3d >> printer so all you have to do is to get some easy to get parts and start >> building. I absolutely hate it when i want to build something and when i >> check the partslist there are exotic parts that you only get from russia or >> korea. >> >> I am sure that most "makers" have every part at home except the big ball >> bearing. >> > Perhaps there is someone or a group out there who would be interested in taking this project on for possible sales that could benefit AMSAT. F.A.Q. Q: Have you seen the rotor article in QST ? A: Yes and I believe this is much better. Q: What about the AMSAT board ? A: It appears that they *might* be open to marketing it as they do with the LVB Tracker and pre-amp. Q: Why don't you just leave us alone and do it yourself ? A: I am old. 73 W9KE Tom Doyle

Couple suggestions.. 1) short USB cable 2) I could not get hrd to control radio correctly for liner inverting sats, check out SatPC32. 3) lots of options for data, look at dire wolf or packet engine pro... one gotcha, 9600 baud packets must go through the data port on rear of radio, USB will not work...

"Bob: You have requested OSCAR numbers for BRICsat and PSAT built by you and your associates at the U.S. Naval Academy. From everything I can determine, these satellites meet all of the requirements for OSCAR designations. Therefore, by the authority vested in me by the AMSAT-NA President, I hereby confer the designation, Naval Academy OSCAR 83 on BRICsat amd Naval Academy OSCAR 84 on PSAT These designations can, of course, for convenience, be shortened to NO-83 and NO-84. I, and the entire amateur satellite community, hope for successful missions for both NO-83 and NO-84 and congratulate you and the rest of the Naval Academy team who designed, built and tested these two OSCAR spacecraft. 73, William A. (Bill) Tynan, W3XO OSCAR Number Administrator" NO-84 PSAT, a student satellite project named in honor of USNA alum Bradford Parkinson, of GPS fame, contains an APRS transponder for relaying remote telemetry, sensor, and user data from remote users and Amateur Radio environmental experiments or other data sources back to Amateur Radio experimenters via a global network of Internet-linked ground stations. PSAT is another APRS satelliite that can digipeat user packets just like the original PCSAT (NO44) and the packet system on the ISS. PSAT also supports the same digipeating alias of ARISS so that users do not have to change any parameters when using any of these three APRS transponders. see http://www.aprs.org/psat.html NO-83 BRICsat-P (Ballistic Reinforced Communication Satellite) is a low cost 1.5U CubeSat built by the US Naval Academy Satellite Lab in collaboration with George Washington University, that will demonstrate on-orbit operation of a Micro-Cathode Arc Thruster (µCAT) electric propulsion system and carries an Amateur communication payload. see http://space.skyrocket.de/doc_sdat/bricsat-p.htm 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 Transponder BRICsat: 437.975 – 9600 baud telemetry evry 20s BRICsat PSK31-6 – same as PSAT but PSK TLM on 375 Hz (PSAT on 315 Hz) [ANS thanks Bill Tynan, W3XO for the above information] --------------------------------------------------------------------- 2015 AMSAT-NA Board of Directors Nominations Notice It is time to submit nominations for the upcoming AMSAT-NA Board of Directors election.

Departure from San Diego will be on Wednesday, June 10 aboard a 49' sailboat. The team plans to be on the air sometime late Wednesday, through sometime on Sunday, June 14, including most of the VHF contest. Unfortunately, they have to leave before the end of the contest because the Navy has scheduled exercises in the area on Monday. Activity includes 6 M, 2 M, probably 432, 1296 and satellites. Phil is responsible for everything other than 6 M. They plan to look for meteor scatter every morning and perhaps the evenings, unless there is Es. Since there is no cell service they 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. The expedition will be running about 500 W and a 3 el yagi (due to constraints from having to mount the antenna on a sailboat). They will use the call K6ZH. Watch for packet spots announcing their transmit frequency.

[ANS thanks ARISS, and Charlie, AJ9N for the above information] --------------------------------------------------------------------- Satellite Shorts From All Over * LightSail Drama Continues as Spacecraft Wakes for Second Time LightSail is back in business, following the second extended outage of the test spacecraft’s mission. The CubeSat checked in at 2:21 p.m. EDT (18:21 UTC) Saturday for the first time since Wednesday afternoon. Over the course of two overflights, 23 beacon telemetry packets were received by the spacecraft's Cal Poly San Luis Obispo ground station. A rapid sail deployment was briefly considered, but with battery levels still unsteady and just one ground pass remaining before an eight-and-a-half hour outage, the team scrapped the idea. When LightSail came around the Earth again, telemetry showed its batteries were charging—the first time since solar panel deployment three days ago. If battery levels continue to trend stably during Sunday’s early morning ground station passes, sail deployment will be scheduled for 2:02 p.m. EDT (18:02 UTC). Engineers have been working to narrow down the reason LightSail’s batteries tripped into a safe mode-like condition following solar panel deployment. Before this afternoon's signal acquisition, the leading theory was that the spacecraft was stuck in a loop where power levels were too low in Earth's shadow, but too high in sunlight. This power ping-pong could have prevented the batteries from reattaching their circuits to the spacecraft and allowing normal operations to resume. The analysis is still ongoing. {ANS thanks the Planetary Society's Jason Davis for the above information] * Goddard Technologist Advances CubeSat Concept for Planetary Exploration Although scientists are increasingly using pint-size satellites sometimes no larger than a loaf of bread to gather data from low-Earth orbit, they have yet to apply the less-expensive small-satellite technology to observe physical phenomena far from terra firma. Jaime Esper, a technologist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, however, is advancing a CubeSat concept that would give scientists that capability. Dubbed the CubeSat Application for Planetary Entry Missions (CAPE), the concept involves the development of two modules: a service module that would propel the spacecraft to its celestial target and a separate planetary entry probe that could survive a rapid dive through the atmosphere of an extraterrestrial planet, all while reliably transmitting scientific and engineering data. Esper and his team are planning to test the stability of a prototype entry vehicle -the Micro-Reentry Capsule (MIRCA) - this summer during a high-altitude balloon mission from Fort Sumner, New Mexico. 'Like No Other CubeSat Mission' "The CAPE/MIRCA concept is like no other CubeSat mission," Esper said. "It goes the extra step in delivering a complete spacecraft for carrying out scientific investigations. We are the only researchers working on a concept like this." Under his concept, the CAPE/MIRCA spacecraft, including the service module and entry probe, would weigh less than 11 pounds (4.9 kilograms) and measure no more than 4 inches (10.1 centimeters) on a side. After being ejected from a canister housed by its mother ship, the tiny spacecraft would unfurl its miniaturized solar panels or operate on internal battery power to begin its journey to another planetary body. Once it reached its destination, the sensor-loaded entry vehicle would separate from its service module and begin its descent through the target's atmosphere. It would communicate atmospheric pressure, temperature, and composition data to the mother ship, which then would transmit the information back to Earth. The beauty of CubeSats is their versatility. Because they are relatively inexpensive to build and deploy, scientists could conceivably launch multiple spacecraft for multi-point sampling - a capability currently not available with single planetary probes that are the NASA norm today. Esper would equip the MIRCA craft with accelerometers, gyros, thermal and pressure sensors, and radiometers, which measure specific gases; however, scientists could tailor the instrument package depending on the targets, Esper said. A Balloon Flight is designed to test stability. The first step in realizing the concept is demonstrating a prototype of the MIRCA design during a balloon mission this summer. According to the plan, the capsule, manufactured at NASA's Wallops Flight Facility on Virginia's Eastern Shore, would be dropped from the balloon gondola at an altitude of about 18.6 miles (30 kilometers) to test the design's aerodynamic stability and operational concept. During its free fall, MIRCA is expected to reach speeds of up to Mach 1, roughly the speed of sound. "If I can demonstrate the entry vehicle, I then could attract potential partners to provide the rest of the vehicle," Esper said, referring to the service module, including propulsion and attitude-control subsystems. He added that the concept might be particularly attractive to universities and researchers with limited resources. In addition to the balloon flight, Esper said he would like to drop the entry vehicle from the International Space Station perhaps as early as 2016 - a test that would expose the capsule to spaceflight and reentry heating conditions and further advance its technology-readiness level. "The balloon drop of MIRCA will in itself mark the first time a CubeSat planetary entry capsule is flight tested, not only at Goddard, but anywhere else in the world," he said. "That in turn enables new opportunities in planetary exploration not available to date, and represents a game-changing opportunity for Goddard." http://www.spacedaily.com/reports/The_CAPEd_Crusader_Goddard_Technologist_ Advances_CubeSat_Concept_for_Planetary_Exploration_999.html [ANS thanks NASA Goddard, and Spacedaily.com for the above information] --------------------------------------------------------------------- /EX In addition to regular membership, AMSAT offers membership in the President's Club.

PSAT downlink
by Mike Sprenger 06 Jun '15

06 Jun '15

So I was able to copy Psat 435 mhz downlink today...nice ! Copying the beacon with digipan was quite easy. Watching the stations move diagonally across the waterfall was an interesting Display of the Doppler on the uplink. Watching the satellite today transmit then cease to transmit then transmit again raises one question. Does someone have to be transmitting to the input of the satellite on 28MHz for the beacon / fm 435 MHz downlink to be active ? Thanks, Mike W4UOO Sent from my iPhone

Steve, It was a full pass, 8 to 9 stations. Was that pass directly overhead for you? I know on a 70 deg + pass, I cannot hear either the first or second half at all, even with a pre-amp on the arrow. I think the whip antenna points right at you on an overhead, or is shielded by the body of the bird, and you sit in the null. Bill W1PA

There is a challenge operating from the deck of a submarine during windy conditions as one tries to keep the gear from ending up in the harbor. The HF operators work from the crew's mess. Info about the Cobia can be found on QRZ.com under NB9QV as well as QSL info. Regards to all, Dave, WN9Q

PSAT Observation
by Roger Kolakowski 05 Jun '15

05 Jun '15

Just had an overhead descending pass in New England and saw PSAT was being pounded by several unattended beacons set for every couple of seconds. One was a 3 and the other a zero. ISS was also in their unproto path. Luckily the SGATEs seem to be down so there is no positive reinforcement for the activity. I can get acks over Canada and over the Atlantic with 10 watts to a vertical but I don't seem to decode noisy signals as well as the old days of ISS Ericksson and PCSAT. I think I'm done for a while until the earth based ops get their stations in order. Nice to have the APRS / UNPROTO activity though! Roger WA1KAT

Getting Started in Satellites Publication--Latest Edition?

When will the next edition of "Getting Started in Satellites" be published by AMSAT? I find it very helpful for me, as my work schedule allows me to get active in satellites again for a few weeks--then long absences (months)---meaning that I frequently have to try to remember what I've forgotten! :-) -- -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296

Re: [amsat-bb] PSAT paths
by Robert Bruninga 05 Jun '15

05 Jun '15

Actually, the best path should be VIA ARISS. There is no need for SGATE, since all APRS IGates automatically send everything they hear to the internet. And if you set VIA PSAT as the path, then you just have to change it again for ISS. So just use via ARISS and both PSAT and/or ISS will digipeat it. PSAT and all other APRS satellite also support the generic space alias of APRSAT, but since the ISS doesn't support that path, then the most generic path is VIA ARISS which will work with all of them. Hope that helps.

1707z PSAT pass
by David W0DHB 05 Jun '15

05 Jun '15

This last pass of PSAT (26deg peak here) I could see packets but never strong enough to decode. I know from APRS.fi that some folks are copying. Also noticed that end of the pass it appeared on the waterfall it was digipeating me, but I couldn't decode. I will try again 1846z pass which is 49 deg here. Dave W0DHB

Best Mast mount PA/LNA?
by Robert Bruninga 04 Jun '15

04 Jun '15

What is the best mast-mount PA / LNA on the market these days. Our old TE Systems amps are now over 15 years old and have only mildly been protected from the weather. Since I am not hearing as well as some other stations, maybe it is time to replace/upgrade? The TE systems had a low noise preamp for receive and 100W amp for TX. We need the amp because we have 150’ of coax to the roof. Do they still make ‘em? So whats out there? Bob, Wb4APR

Re: [amsat-bb] WD9EWK @ Show Low AZ hamfest & weekend grid expedition (6-7 June 2015)
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Jun '15

03 Jun '15

Hi Dave! I'm not going to do much with PSAT this weekend. If there are PSAT passes when I have a break, I might give the 2m digipeater a shot. Otherwise, I'll try PSAT after the weekend. ISS passes, on the other hand, will be attempted if I'm not driving. Please use APRS messages, or insert a ">" before typing a line of text, so that I see more than just your call on my screen. If I only see a call on my screen, even if you were typing at me, I won't log that as a QSO. I was not planning to do much from DM46, but Saturday evening via AO-73 is probably the best chance for that. Maybe Sunday morning, if I get up very early, where I can work an early FO-29 or AO-7 pass before I set out for DM47/57. I won't have the benefit of freeways in my travels up there, so I will need to watch my speeds on the highways across that part of Arizona (and southern Utah). I'm hoping the APRS digipeater on Navajo Mountain has some coverage where I'm going, being several thousand feet higher than the surrounding area. When I was last out this way in 2009, I didn't have anything for APRS with me. 73!

PSAT: Breaking its "squelch"
by Bob KD7YZ 03 Jun '15

03 Jun '15

I noticed on a few passes that during the time I can see/decode/hear the ADO Beacon, that if I transmit on 28.120, I can then see what looks to be my downlinked PSK31 signal. There IS Doppler drift on it, fwiw. If I keep repeating the CQ PSAT, then I still hear the telemetry from PSAT (usually ADO) and I see one or two other stations. But if that downlink stops, then no mater who long i transmit, that PSAT "squelch" is not broken; I never hear or see the ADO beacon. Somehow something else breaks that squelch then my CQ-ing appears on the now-open WF. I am using MIXW 3.1.1, a SignaLink on K3(28.120) and a Signalink on the IC910H. Are my settings bad? 73, -- Bob KD7YZ http://www.qrz.com/db/kd7yz AMSAT LM#901

WD9EWK @ Show Low AZ hamfest & weekend grid expedition (6-7 June 2015)
by Patrick STODDARD (WD9EWK/VA7EWK) 03 Jun '15

03 Jun '15

Hi! I will be on the road this weekend, starting this Friday evening (5 June) with a 3-hour drive to eastern Arizona before a Saturday (6 June) morning hamfest. After the hamfest, I will be driving and operating from grids in northern Arizona and southern Utah before I return home Sunday night. I'm not able to extend my weekend, so this will be a rapid-fire road trip covering over a thousand miles and several grids. My activities will start with the White Mountain Hamfest in Show Low, in eastern Arizona. This hamfest is a half-day event, and I will have an AMSAT table at it, complete with satellite demonstrations during the morning. If you hear WD9EWK on the air Saturday morning, please call and be a part of the demonstrations. I hope to be on some AO-7, SO-50, and AO-73 passes before the hamfest wraps up around midday (1900 UTC). After the hamfest, I will head north up to I-40. If the timing is right, I may be able to make a stop at the DM54/DM55 grid boundary for the AO-7 and FO-29 passes between 2030 and 2100 UTC Saturday afternoon. If the timing isn't right, I will at least try for grid DM54 near the hamfest to get that on the air once, before heading west to Flagstaff. Once I'm done with DM54 or DM54/DM55, it will be a 4-hour drive to Page AZ, at Lake Powell and the Arizona/Utah state line, passing through Flagstaff as I leave I-40 and start on US-89. I may be able to work from grid DM45 on the way to Page - including some ISS passes. Between Flagstaff and Page, I don't plan on making many stops, as US-89 passes through the Navajo Nation reservation. If all goes well, I will wrap up Saturday in Page, in time to work the AO-73 pass around 0353 UTC. Since the Arizona/Utah state line - and the DM46/DM47 grid boundary - are very close to Page, I *may* be able to work from that grid boundary. At this part of the Arizona/Utah state line, the grid boundary is just inside northern Arizona. Sunday (7 June) morning... my plans are to leave Page early, and make it to a spot in southern Utah north of Monument Valley (grids DM47 and DM57) in time for the SO-50 and AO-73 passes in the morning. I am not planning to make stops along the road between Page and the DM47/DM57 grid boundary, as I will need around 2 hours to get to that spot in time for the first SO-50 pass around 1510 UTC. The first AO-73 pass at DM47/DM57, around 1545 UTC, has a maximum elevation of 4 degrees. I should be able to work a few minutes of that very shallow pass out there, if my memory of that area from being out there in 2009 is correct. Depending on how well the morning passes go, and how the weather is on Sunday, I may try to stick around for the first FO-29 pass up there at 2135 UTC. If I work lots of stations on the morning passes, I will move to one of two other locations for the 2135 UTC FO-29 pass: DM56/DM57 grid boundary just inside southern Utah, or the Four Corners Monument (only in grid DM56, about 100 yards/meters south of the DM56/DM57 grid boundary) to work from 4 states during that pass. If the weather goes bad, I may start my drive home early, but still try to work passes as I return to Phoenix. Wherever I end up for the 2135 UTC pass, that will probably be the last pass I work up there before I (quickly) drive home. From that area, I will have a 5- to 6- hour drive to get home. If I can work the 2135 UTC FO-29 pass from the Four Corners Monument, I will probably use only one of my FT-817s and work the pass half-duplex. This would make it easier for me to walk around the marker where the four states come together. Otherwise, I'll work FO-29 with my normal SSB satellite setup wherever I happen to be at that time. Logistics... I will use APRS as I drive, squawking as WD9EWK-9 as I normally do on these trips (visible at http://aprs.fi/WD9EWK-9 among other online places). This should do OK for much of my trip, but coverage could be spotty in northeastern Arizona and southeastern Utah east of Page and Lake Powell. There is a digipeater on a 10000-foot mountain near Page, but I'm not sure how well it will cover across the high deserts up there. I will also use my @WD9EWK Twitter feed to post updates during the weekend. If you do not use Twitter, it is visible online at http://twitter.com/WD9EWK without signing up for Twitter. Depending on how the mobile-phone networks across the Navajo Nation reservation have improved since I was last up there in 2009, I may be limited to using SMS messages to post updates to Twitter. For all of my operating over the weekend, I will upload my QSOs to Logbook of the World after the weekend. I will also prepare QSL cards for each of the locations I work from. Just drop me an e-mail with the QSO details, and I'll send you a card (or cards). No need to send me cards or an SASE for this trip. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

I had been receiving and decoding PSAT telemetry on the 2 m downlink pretty consistently up until the digipeater was turned on. Now, I hear the packets on the radio, but they are not strong enough to be decoded. Has the power been reduced on the 2 m downlink? Steve AI9IN

14:00u 12degree pass of PSAT this AM. Very weak signal as expected, also the satellite doesn't hear well. I heard several weak packets that did not display. None were a digi of my packets. I was able to copy one telemetry packet. 1:Fm PSAT To APRSON Via ARISS <UI pid=F0 Len=34 >[06:58:42] T#209,873,086,131,131,412,00000000 The ISS and PSAT were both in range during part of this pass.

PSAT and BRICsat oscar numbers?
by Robert Bruninga 02 Jun '15

02 Jun '15

To Whom it may concern: We request OSCAR numbers for PSAT and BRICsat. PSAT is fully operational as APRS digipeaer and as PSK31 transponder BRICsat has been heard with Telemetry and its PSK31 transponder has also been heard though weakly. Request NO## and NO## with PSAT getting the first number. If precise ## are negotiable, contact me direct. Bob Bruninga, WB4APR Lastname at usna.edu

PSAT and HDSDR
by Tom Schuessler 02 Jun '15

02 Jun '15

For those interested, the PSAT signal works very well with HDSDR on a FunCube Dongle Pro+. You can control the "Tune" frequency from SatPCC32 or in the case of an FM carrier like PSAT, let the quite decent FM AFC on HDSDR track the frequency of the downlink. I purchased a "Virtual Audio Cable" driver from Eugene Muzychenko Software. http://software.muzychenko.net/eng/vac.htm It is fully functional in trial mode but the watermark will drive you nuts. The nice thing is that you can direct the output for the FCDPP to whatever software you are using and also to redirect it to a secondary soundcard for you to hear. Next weekend I will try WinPSK to see if it works in satellite mode full duplex. This will negate the need to run two instances of digipan to hear myself while transmitting. 73 Tom, N5HYP

Re: [amsat-bb] ISS packet double hop?
by Robert Bruninga 01 Jun '15

01 Jun '15

When PSAT is near ISS, watch for double hop packets! PSAT sends its telemetry packets via ARISS. Best chance of this happening is when ISS is way out far over the ocean and has little QRM on its 145.825 uplink. AND then PSAT, with its 0.3W transmitter will have to be close to ISS too. If you see one, let us know. Bob, WB4APR -----Original Message----- From: AMSAT-BB [mailto:[email protected]] On Behalf Of Cor PDØRKC ... ISS packet system ... was... off.

by Robert Bruninga 01 Jun '15

I just turned on the PSAT digipeater. You will notice that its callsign in this mode is just “PSAT” and not PSAT-1 when it is in SAFE mode. The ALIASes supported are ARISS and APRSAT. The PSK-31 transponder also remains in AUTO mode meaning it will come up whenever there are PSK31 signals on the 28.120 + frequency. Bob, WB4APR

Re: [amsat-bb] PSAT key to success
by Robert Bruninga 01 Jun '15

01 Jun '15

Until we get authors adding Full duplex and AFC to their PSK31, here is a scheme that will work. Focus on the OVERHEAD pass. Horizon to Horizon. Because during these passes, the satellite is coming right at you for the first 5 minutes, and directly away from you for the next 5 minutes. This means the Doppler is nearly constant high during the first 5 minutes and then a rapid shift to a constant LOW for the last 5 minutes. And horribly shifting for the middle 1 minute. Your signal will have very little Doppler on the downlink and most anyone with any kind of PSK31 decoder will decode you fine. Don't do any frequency transmitteirn shift on the uplink or as KO6TZ says, you will cause people to lose lock.. When the satellite crosses overhead, you can then shift your TX frequency UP by 1.15 KHz and people will see you more or less back where you started... maybe.

From me experience on DO-64 and FO-29 using PSK31/63, I found adjusting for Doppler on the SSB up-link is a double edged sword. When the frequency is updated for Doppler, you loose sync for a few characters. If you don't correct the frequency, you will exceed the AFC limit of most programs, except WINPSK. WINPSK doesn't support multi line copy. Also using DigiPan in "munti" mode, there is no AFC. The s/w just creates another line. Pick your poison.....

LightSail identified
by Nico Janssen 01 Jun '15

01 Jun '15

All, Using detailed doppler shift measurements, I find that LightSail is object 90726, ULTRASat 7, without any doubt. This means that LightSail is actually object 40658, 2015-025H in the JSpOC catalog. The preliminary initial assignments in the JSpOC catalog for the objects in this launch will need to be corrected: PSAT = 90720 = ULTRASat 1 = 40652 = 2015-025B LightSail = 90726 = ULTRASat 7 = 40658 = 2015-025H BRICSat = 90729 = ULTRASat 10 = 40661 = 2015-025L 73, Nico PA0DLO

PSAT 2100z 5/31/15 pass CM98
by Greg D 31 May '15

31 May '15

Hi all, Tried listening for PSAT for the first time, and had a really nice pass. I don't have the 10m uplink side configured, and this was all manually tuned. So I still have a bit of work to do, but the results exceeded my expectations. Signal peaked at S6 or so, full quieting. I think the Keps (object 90721 Epoch 150.54728009) were a little ahead of reality, maybe 30 seconds to a minute. There was some QSB, but it could also have been my coarse antenna rotation and manual tuning. Radio was a Yaesu FT-847, 2x16 element beam, and with FLDIGI on my Linux box, using the internal (motherboard) sound card.

I have for sale a Cushcraft 214 two meter beam. This beam covers 144-146mhz and has 15 elements on a 15 foot boom, 15.5 dB forward gain and a 24 DB F/B radio. Good condition it just needs a boom to mast clamp, something you can probably make up yourself. This would make a nice uplink antenna for Mode J, or Mode B receiving antenna. I am asking $60 plus shipping for it. Pickup is also possible in SW Oklahoma area. I can take paypal/check/MO. 73 John AF5CC

4 stacked 70cm yagis for sale
by John Geiger 31 May '15

31 May '15

I have for sale a set of 4 10 element 70cm antennas. These have 6 1/2 foot booms and are end mounted. With these antennas comes the H frame stacking framework with mounting brackets. The stacking distance is 3 feet by 4 feet. It also comes with the power divider for the 4 yagis. Everything you need to get the 4 bay system going is there. The antennas are homebrew but very well made, resembling M2 yagis. This system has been used for 70cm EME with good results. The 4 antennas have a common horizontal cross boom to mount in an elevation rotor if desired. I would prefer a face to face deal but shipping is possible if you are willing to pay shipping. I can meet someone in the OKC area, around the Dallas/Fort Worth area, SW Oklahoma or North Texas. You can come to Lawton, OK and pick them up also. It might be possible to deliver this setup to Central States conference in July as well. I am not sure exactly what these are worth, but will entertain offers. This setup will give you a big signal on mode B, or great reception on Mode J, that is for sure. 73 John AF5CC

PSAT PSK31 downlink
by David W0DHB 31 May '15

31 May '15

I've been observing that with the current keps the Downlink frequency of the PSK31 beacon is about 2Khz low. A good US pass over the US at about 1936. What I have been doing is decoding the entire 3 KHz with DM780's Supersweeper or Fldigi and fixing TX at about 600Hz. That way I catch everybody and there is no need to match frequencies. I've been trying to TX below 1KHz to minimize interfering with folks operating normal 10m PSK. Dave W0DHB

Nick passed away on May 24 from an aneurism of the aorta. Nick was a smart, caring, considerate and helpful person that loved the amateur radio hobby. As the primary amateur radio license trainer for the ISS astronauts, Nick played an integral role in encouraging and training countless astronauts (US, Canada, Japan and Europe) to pursue their amateur radio license and become active on ARISS. He inspired and trained dozens of NASA's aerospace education specialists (who talk to schoolteachers nationwide) to get their ham tickets. He also taught a "Hamster" course to middle schoolers, inspiring them to pursue careers in technology through Amateur Radio and ARISS activities. Personally, I enjoyed working with Nick both as a NASA engineer and an amateur radio operator. I will miss his quick wit and sense of humor. Nick will be deeply missed by many. A Celebration of Life for Nick Lance will be held Sunday, June 14, 2015, 2 p.m. at the Gilruth Center. A map to the public entrance of the Gilruth Recreation Center, Building 207 http://ewh.ieee.org/r5/galveston_bay/events/GilruthCenterMapandDirections.p… A flag will be flown over Mission Control and presented to Renee and the family.

Activity will be on 80-2 meters using CW, SSB and RTTY. They will also participate in the ARRL VHF Contest and some satellite operations (FO-29 only on selected passes). The two primary radios will be Elecraft K3's with 500 watt amplifiers. Antennas include a Mosley Classic 33 on 10/15/20, a folding hexbeam by Folding Antennas (Germany) on 20-10 meters, verticals on 30 and 40 meters, a dipole on 75-80 meters, and an M2 5 element 6 meter beam. They will run 500 watts on 6m SSB/CW and FSK441. A 6 meter beacon is planned and will be on 50.102 MHz when the station is not manned, and the receiver will be active between beacon transmissions to listen for calls. The primary callsign for the operation will be VP2MKV, and VP2MTT will probably be used on 6 meters. Near 24 hour operation is planned. Tentative satellite pass plan for VP2MKV operation: They will attempt to be on the first two FO-29 ascending node passes June 11th through 20th. If time allows they may be on the third ascending node those days. Those passes happen in late morning to mid afternoon Montserrat time. On those passes they will look first for South America when the satellite is south of them, then North America, then Europe during the short mutual window. If there are 2 meter or 6 meter terrestrial openings during the VHF contest June 13th and 14th, they will not be on satellite at those times. Logs will be uploaded to LoTW soon after the group returns to the US. Paper QSLs via N0KV, direct or via the bureau. US addressees send SASE; addressees outside the US send SASE plus 2 USDs for return postage. Use of ClubLog has not been finalized at this time. Additional information will be posted under VP2MKV on QRZ.com.

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 telemetry data is sent on a downlink of 437.435 MHz, AX.25, 9600 bps FSK.

Universities and other scientific research institutions are using portions of the amateur spectrum for their CubeSat’s which has caused the 145 and 435 MHz amateur-satellite band segments to be very crowded, leading to an increasing number of satellite builders to explore alternatives. For many, such as those requiring single-channel bandwidth greater than approximately 12.5 kHz, the best answer will be found in the microwave bands. However, for those who can use it, the International Amateur Radio Union (IARU) satellite frequency coordination process has now opened another alternative: 29 MHz uplinks.

PSAT PSK31 downlink & power requirements
by KO6TZ Bob 31 May '15

31 May '15

For the afternoon pass 21:17u @ 52 Deg, I used Dave's method and NOT try to match up signals. Use a program that decodes all of the signals and try to reply to as many as I could. With some practice, that should work out better. I don't know if Glenn copied me or not. He was the only satellite CQ I saw. As for power: I can barely see my signal using my di-pole. When I used 85 watts 70% ALC into a 1/2 wave vertical, (10m Ringo) I was able to turn on the FM transmitter and saw a good clean, 21 IMD, signal on the down-link. I have no idea what it looked like for the terrestrial users. I did not have to wait for the telemetry to turn on the FM transmitter, and I did not splatter across the waterfall of the down-link. More practice coming. BOB KO6TZ

LightSail-A Reboot
by Gregory Beat 31 May '15

31 May '15

The Cal Poly ground station detected a reboot of the onboard computer. Cause of reboot unknown, but welcomed to resolve communication issue. https://t.co/XphRtq5hD4 The RTC shows 908,125 seconds (roughly 10.5 days). Software patch will be loaded by ground stations (Cal Poly or Georgia Tech), to prevent re-occurrence of this outage. Two-way communications will be attempted tomorrow. http://sail.planetary.org greg, w9gb -- Sent from iPad Air

W1AW/0 MN Medallions
by Rolf Krogstad 30 May '15

30 May '15

Today I got a surprise in the mail. The ARRL sent me two commemorative medallions mounted in a plexiglass display which is engraved "NR0T was W1AW/MN" Very sharp looking addition to the shack. I worked only Satellite QSOs on both of the Minnesota weeks. It is a beautiful commemorative gift and caught me totally by surprised. Thank you ARRL! 73 Rolf NR0T grid = EN34it Memeber of the following organizations: ARRL Life Memeber Minnesota Wireless Association Twin Cities DX Association AMSAT AMSAT-UK

Re: [amsat-bb] PSAT - power requirements

> > > WB4APR recommends no more than 25 watts. > That was the design goal, but until we get more experience, we wont know for sure. But since everyone can see their own downlink just like everyone else can see it, it should be no problem adjusting for minimum uplink power. But with any shared transponder it can also become an arms race. As one person increases power it drives the AGC down and everyone else goes down, so they also increase power and this just keeps going until the AGC is maximally tightened and everyone is transmitting max power and everyone is weak. What we really need (BEFORE this happens) is for everyone to give us feedback as to the minimum power they needed to maintain a minimum signal in the passband and of course, what kind of antenna they are using under those conditions. And this is best early on when there are only 1 or 2 usewrs at a time.. If you don't yet have PSK31, but want to get some data, team up with an HF friend in your area and ask him to just transmit for the next 10 minutes and you can then receie his downlink while commenting on his signal strength throughout the pass. >The prelaunch orbit estimate I saw was a 700 km x 350 km orbit with an expected orbital lifespan of 3 years. I'm not sure how close that is to the final orbit. We don't know yet either, but perigee is nearer the morning passes and apogee is nearer the later passes (THis is for the Northern Hemisphere.). Both apogee and perigee being near the equator. Bob, WB4aPR On family travel and with very spotty Email till next week.
