At http://www.amsat.org/amsat/ftp/keps/current/nasa.all the file does not contain orbital data of ARISSat-1 at any name. On http://www.amsat.org/amsat-new/satellites/satInfo.php?satID=136&retURL=/sat… <http://www.amsat.org/amsat-new/satellites/satInfo.php?satID=136&retURL=/sat…> there can be found three different names:RadioSkaf-V, KEDR and ARISSat-1. Beside these on http://www.celestrak.com/NORAD/elements/amateur.txt you can find RADIOSCAF-B at the very end. (Wrtten with capital C, not small k or capital K...) Can anyone or any organization agree in a common name, please? As for me I would prefer AO n+1 or anything you like but for God's sake give it a common name asap! Time passes and ARISSat-1 slowly approaches the Karman border and it will dissolve finally! gl de ha6nn Andras

Only if you had your station, or parts of it, on the boundary or intersection. Again, the complete VUCC rules can be found at the following link: http://www.arrl.org/files/file/Awards/VUCC%20Rules%202011_Rev%2020110512.pdf Please read through sections 4(e) regarding stations located at grid boundaries and intersections and 4(f) regarding GPS receivers and their requirements. That should answer questions about locating the stations *on* the line/intersection and not just *near* those spots. If you have more questions about these rules, ARRL now has a new e-mail address for VUCC-related matters: VUCCaward @ arrl.org If the VUCC rules were as liberal as you mentioned about county hunting, I'm sure many more grid boundaries and intersections could be on the air. It would be so much easier, and that may have been some of the motivation in the rule changes a couple of years ago. I know of several different places I could put on the air where I could see the intersection of 4 grids, but can't actually put my station on the spot due to property ownership (DM32/DM33/DM42/DM43 is in a farmer's field south of Phoenix - I usually work from DM32/DM42 just south of this spot along a road) or safety (DM35/DM36/DM45/DM46 is just inside the Grand Canyon, north of its South Rim and east of Grand Canyon Village) - among other places. 73!

Just wanted to say thank you to everyone for the satellite contacts during the ARRL Rocky Mtn. Convention in Taos. We had hundreds of people stop by during the event with tons of interest in AMSAT and satellite operating. Special thanks to Rodney, KC0ZHF, for his help during the passes. Early on we had rotor control problems due to a bad USB<>serial interface driver. Having Rodney there to make the contacts while I adjusted the AZ/EL was a lifesaver. He also helped answer many of the questions coming our way about working the birds. I put some pictures online of the station setup on my QRZ page. 73, Ollie AJ1O > > > Date: Fri, 5 Aug 2011 20:10:44 -0700 (PDT) > From: Rodney Waln <kc0zhf(a)yahoo.com> > Subject: [amsat-bb] W1AW/5 Taos, NM > To: "amsat-bb(a)amsat.org" <amsat-bb(a)amsat.org> > Message-ID: > <1312600244.45256.YahooMailNeo(a)web46105.mail.sp1.yahoo.com> > Content-Type: text/plain; charset=iso-8859-1 > > http://www.2011convention.org/w1aw.html > ? > aj1o?and kc0zhf will be operating and demoing from the 1973 pinzgauer > and tripod trailer as w1aw/5 on numerous satellite passes from dm76 please follow instructions > for qsl on the above link, Fri, sat and Sunday morning from the convention, > hope to work you, > >

Diamond A430S15 Antenna Dimensions

Hi Group, First of all, sorry for the bandwidth. I am trying to model a new satellite system for the V/U/L/S bands and wonder if anyone happen to have the element spacing for the Diamond A430S15 yagi. Unfortunately, the manual provides only the individual element lengths, but not the spacing between elements. I have tried searching on the net but unfortunately failed to find any positive results. Any pointers to this are truely appreciated. Thank you. 73, Sion Chow Q. C., 9M2CQC, Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

gps accuracy
by jerry keeton 08 Aug '11

In regaurds to gps accuracy , You must remember to give the unit sufficient time to update the correct coordinates . Usually takes one minute of stationery movement to get the correctly display . While searching for survey corners , I was actually walking "past" or "over" monuments because the gps unit was not keeping up with My steps . If You are trying to confirm four courners , It's going to take You several minutes to correctly confirm 4 different coordinates . Just a thought . Jerry WB5LHD

iss beacon receive and vhf preamp
by N. Mahdinejad 08 Aug '11

08 Aug '11

Dear amsat members. I have some question about receiving beacon signal from ISS. Could you please help me? 1. What is the difference between ISS, ARISS and ZARYA? Is these different satellites or 1 satellite with 3 name? 2. Which of them is easier to receive beacon from them? 3. Frequency of beacon signal of ISS is in VHF band. Is it available without preamp? I use 2 preamp. One for VHF and 1 for UHF band. But the preamp in vhf band isn’t on. I mean that icom receiver could not supply it. I activate preamp in vhf band in set menu of icom radio. The uhf band preamp on and I use it. But for vhf when I push the preamp button in front panel of icom the preamp writing is visible for 2 seconds and then turned off and isn’t visible. Any help would be gratefully appreciated. Beat Regards. N.Mahdinejad

WORK-AROUND FOUND! RE: ARISSat TLM soundcard selection

OK ! So there is no way to select between either the soundcard (read output from HDSDR) or the FCD (which is in the system also a soundcard. BUT: here is the work around; step 1: disconnect the FCD step 2: start ARISSatTLM (only th normal sound card is present, which it selects) (not: in the Tuning indicator no signal is seen) step 3: plug in the FCD (into the USB port of the PC) step 4: start HDSDR >>> and now ARISSatTLM shows the output of HDSDR Voila (the French would say) Henk -----Oorspronkelijk bericht----- Van: Sion Chow Q.

Mirage kpc1 problems
by Richard Lawn 07 Aug '11

07 Aug '11

I suspect that one primary reason I'm not hearing the birds as I try several home brew stationary antennas is the used 440 preamp I bought on eBay. It seems like the internal TS-2000 internal is better and that shouldn't be. And just when I'm getting results with these home brewed antennas! Is there any way I can verify failure in the mirage kpc1/440? I too got tired of mistakenly putting too much rf in an old ARR preamp I had and fried it, suggesting that I switch to the mirage amps like those I use at the home qth with good results. Rick W2JAZ

WTB: 70cm all mode radio
by John Geiger 07 Aug '11

07 Aug '11

I am looking for a 70cm all mode radio to use on VO52, AO7, and FO29. I have 2m already covered with an Icom 706 original, so just need something for the UHF side of things. Something like the FT780, FT790, FT790RII, TS811, TR851A, TR9500, TM455A, IC 451, IC 471, IC490.or FT726 with UHF module. I would also be interested in a yaesu FT100D or FT857D for the right price. It needs the mic and power cord. Any other accessories aren't really needed. Let me know if you have one for sale. 73s John AA5JG

MacBook running MacDoppler interface to radio
by James Luhn 07 Aug '11

07 Aug '11

I have both PC and Mac computers. I enjoy using both and have each computer doing things that they seem to do the best. I am looking for some suggestions on what interface I should be using to have MacDoppler running on a MacBook Pro control an IC-910. I have the CT-17 level converter for the IC-910. When running from a PC(for this and mobile I use a Panasonic CF-29 Toughbook. It has a serial port!) I simply connect the serial port to the CT-17 and all works fine. I do have a USB to Serial converter (U232-P9) that has Mac drivers. I cannot seem to make the Macbook, usb-serial adapter, and CT-17 work. For those running MacDoppler, how are you interfacing to the IC-910 or other radios using a serial port? Thanks, 73, James W5AOO

Reception of FSK signal by TS 2000x
by Kumar Kshitiz 07 Aug '11

07 Aug '11

Hi , I have to transmit FSK modulated data from a transmitter chip towards Transceiver(TS2000x) so that I can receive the data in computer. I am able to control the internal TNC of TS2000x through a software called Pacterm. Even if the signal power is being displayed on display panel, no data is being received in computer. I have an option of using the UNPROTO mode in internal TNC. I am sending AX.25 UI frames to the transceiver. Even then, nothing appears on computer screen. The parameter RXERROR count also does not increment (which could have stated otherwise that the packets are rejected). Can you just tell me what can be the possible cause? and solution too.. I can also use KISS MODE (found in transceiver datasheet) but there is no data display in that also though it says it does not do any packet operation on this mode and directly forward the data to computer..

Activating EM04, DM94 and EL39 this week
by Clayton W5PFG 07 Aug '11

07 Aug '11

On Monday 8-Aug and Tuesday 9-Aug, I will be traveling the EM03-04/DM94 corridor between Dallas and Amarillo,Texas and plan to make at least one AO-51 pass. On Thursday 11-Aug, I will be operating late afternoon passes of AO-51 from EL39, just a few miles south of EM30. I may work passes of SO-50 or AO-27 depending on my schedule but I'll focus on AO-51. I'll be running APRS as W5PFG-9. Through past experience I have discovered the coverage of "Smart" Digipeaters in the EM04-DM94 area is "limited." Please reply privately to this email if these are grids you need so that I might accommodate the passes in my business travel. 73, Clayton W5PFG

Re: ARISSat TLM soundcard selection (and submission listings)
by PA3GUO 07 Aug '11

07 Aug '11

Hi Sion, Great suggestion. Another suggestion: Not for us experimenters, but for schools / teachers / others / .. : ARISSatTLM setup under Win7 worked fine, the assumed directory for the TLM storage was indeed used. For Win XP this did not work: I got an error message when starting ARISSatTLM, it looked for the directory on the wrong place (it was created somewhere else). So I moved that directory to the place it was looking for it, and it works. I know there is a heads up on this issue during the install process, but still. For those many new people we try to interest (those 1+ million AMSAT reached with the press release), it would be good to fix this. Just my 2 cents. Henk (btw: the SW overall looks good & quite appealing (also important in this case), it seems to incorporate the best ideas of recent other space programs, including Delfi-C3, RAX, ..) Another idea (maybe this is already in place and I missed it) It would be nice to have on the ARISSat telemtry website (latest values) an overview of which stations submitted the data (they entered their callsign under 'tools'). That would highly motivate new people to contribute. Imagine you are a student, and build a receive set-up, and can show your teacher your name/call is listed on the official ARISSat website !

Hi Henk, I seem to have the same problem as you do, and how I overcame it is to ensure that the sound card that you want ARISSatTLM to use is the default system sound card.

Hi Glenn, I haven't made a QSO yet either. The biggest problem, I think, is the satellite's tumbling, which results in frequent obstruction of the little uplink antenna by the main body of the spacecraft. On this pass, when I could see the uplink antenna, you couldn't, and vice versa. The rapid Doppler, due to the low altitude, doesn't help either. I'll try again tomorrow morning. 73 Ray In a message dated 8/7/2011 2:42:54 P.M. GMT Standard Time, aa5pk(a)suddenlink.net writes: I wish I'd heard you calling, Ray.

Orbital lifetime of ARRISat-1
by DeYoung James 07 Aug '11

07 Aug '11

Greetings, If you were a member of AMSAT-NA you would receive the AMSAT Journal and could have read the article I wrote for the last issue concerning the predicted lifetime of ARRISat-1. The paper presented predictions for up to a maximum release height of 370-km and there is enough information to extrapole to the higher release height as realized. The recent reboosts put the release height somewhat higher but I would guess a lifetime of about one year. The actual Sun-state influences the atmospheric densities of the future that ARRISat-1 passes through will control the actual lifetime. Even tho I am all packed up to move to my retirement home I will write a short update to that paper using the actual release height and submit it to the Journal. I would encourage everyone (if you aren't a member already) to join AMSAT-NA and read the journal there is a lot of good stuff there. Jim, N8OQ

August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.03 ARISSat-1/KEDR was deployed from the ISS during EVA-29 on Wednesday, August 3 by Cosmonaut/Flight Engineers Sergei Volkov and Alexander Samokutyaev. First reported signals were received by JR8LWY with copy of the telemetry beacon as the satellite passed over Japan. Full operational capability of ARISSat-1/KEDR was quickly confirmed after initial concern of a missing or damaged 70cm receiver antenna on the satellite. 145.950 MHz FM Downlink - OPERATIONAL ------------------------------------- FM transmissions will cycle between a voice ID as RS01S, select tele- metry values, 24 international greeting messages in 15 languages and SSTV images. One of the messages will be a conversation between Yuri Gagarin and ground control.

It is an 16 KHz wide inverting passband and the convention will be to TX LSB on the 435 MHz uplink and RX USB on the 145 MHz downlink. The full status of the 70cm antenna is unknown however reports of contacts and full uplink-downlink operation are being received: + Drew, KO4MA reported on August 4, "I was able to hear myself with as little as 1 watt on the 0425Z pass". This equates to an EIRP of as little as 26 watts which can be easily produced by even modest satellite stations. Audio with a picture were posted at: http://www.youtube.com/watch?v=0AFyZNAbOeA + John, K8YSE reported completing an unscheduled contact with KD8CAO on August 5 at 1125z.

August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.05 ARISSat-1 was deployed from the ISS on August 3. It has a composite VHF downlink that will easily fit into the FUNcube Dongle (FCD) re- ceive spectrum. The 145.920 MHz telemetry is 1000 bps BPSK and can, of course, also be received with a normal SSB 2 metre receiver. The signal levels from ARISSat-1 should be similar to those we expect from the AMSAT-UK FUNcube-1 satellite (and also eventually from UKube-1) and the AMSAT-UK team are keen to discover what will be the minimum and best type of antennas for schools to use with a FUNcube Dongle (FCD) Software Defined Radio (SDR). Therefore user experience with the ARISSat-1 signals will be very valuable in making this determination. To encourage everyone to receive the 145.920 MHz BPSK ARISSat-1 tele- metry signal AMSAT-UK are offering a FUN reward for listeners! There are a number of categories for this challenge -they include: + The first FCD user, from each continent, who can post a spectrum recording of the received signal together with evidence of decoding the data using the ARISSatTLM software and of sending it to the ARISSat data warehouse. + The first non-FCD user, from each continent, who can provide evidence of having decoded the signals and of sending it to the ARISSat data warehouse. + The listener, using a FCD or not, who can demonstrate satisfactory reception of the telemetry in the same ways as described above, using the "smallest" possible receive antenna. The actual closing date for this part of the challenge will be announced later. + All other entrants who can demonstrate that they have been having FUN!

August 7, 2011 To All RADIO AMATEURS BID: $ANS-219.06 July 24 marked the 40th anniversary of AMSAT's original SYNCART proposal to NASA, in 1971, to fly a Synchronous Amateur Radio Transponder on NASA's Applications Technology Satellite ATS-G. NASA's response to our proposal appeared to be favorable, but unfortunately NASA cancelled the ATS-G mission. The SYNCART proposal is on AMSAT-DL's web site at for those who would like to read it. It gives the justification why NASA should fly it for free, listing a number of amateur experiments and applications, most of which would still apply today. The 1971 WARC on Space Technology was held around the same time (June 7 - July 17, 1971, in Geneva). That's the ITU conference that established the amateur-satellite service and allocated frequencies to it. Several satellite manufacturers are now advertising that they host pay- loads aboard their satellite platforms. Think how it would transform amateur radio if we could get SYNCART packages aboard one or more of them!

Successful ARISS Contact with United Space School On Saturday, July 30 a successful Amateur Radio on the International Space Station (ARISS) contact was held between students at United Space School in Seabrook, Texas and Mike Fossum, KF5AQG on the ISS. Station W6SRJ in California provided the connection. The United Space School is a once a year session of high school students that meets in the NASA/Clear Lake Area. Students come from around the world for a two week session, during which they stay with local host families while being mentored by astronauts, engineers, and scientists to design a mission to Mars as their team project. Class sessions are held at the University of Houston at Clear Lake. Students are given lessons on amateur radio and through the ARISS contact they learn firsthand what spaceflight is like. They will use this knowledge in their team project, which they will present to the Houston space community at the end of their session. 2.

ARISSat-1 over West Malaysia 07 Aug 0202 UTC
by Sion Chow Q. C. (9W2QC) 06 Aug '11

06 Aug '11

Dear All, Had a 20 degree elevation pass in sunlight of ARISSat-1 over West Malaysia at 0202 UTC, 07 August 2011. Managed to copy and forward 21 telemetry and kursk frames to the ARISSatTLM server, and this time I had SATPC32 adjust the doppler in 10 Hz steps. Although the doppler correction seems to be a bit too frequent, but it made the CW signal stay on the yellow marker fairly accurately. However, due to fading only 21 frames were copied. I guess the copying would be better if the fading rate is reduced. Still experimenting with this mode, and hope that the above will be useful to someone. Also noticed from previous observations that it is difficult to get a lock when the satellite is in low power eclipse mode, as the TX gets turned off too quickly. Have a great weekend to all. 73, Sion Chow Q. C., 9M2CQC, Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

While we are about it, although I don't wish to add to the names - RS01S, Skafandr-B, Arissat-1 - shouldn't she have an Oscar designator?

ARR Preamp Help
by Zachary Beougher 06 Aug '11

06 Aug '11

Hi All, I was monitoring some passes while mobile today, and amidst all of the confusion of messing with coax and frequencies, I accidently transmitted on 440, through the preamp, with 35w (the relay is rated at 25w). I thought I had switched the VFO back to 2m, but I guess not. It was only for a split second, but since that every time I turn the preamp on it automatically knocks out all received signal. Does anyone have any idea on what I need to do/check to see what I did to it? I have heard of this happening, I just need to know what path to take now to get it fixed. It is worth mentioning that I can receive fine with the preamp in-line, but the minute I throw the power switch it knocks out all receive (just static, no received audio). I have not changed any of the connections, so having a coax hooked up backwards is not the issue. Thanks, Zack KD8KSN

Anyone using an FT-847 and SignaLink USB to copy ARISSat-1 BPSK telemetry?
by Alan P. Biddle 06 Aug '11

06 Aug '11

Hi, Has anyone used an FT-847 and SignaLink USB to copy, or attempt to copy, the BPSK telemetry? Reports of success or failure equally useful. In either case, it would be helpful to know approximately when the rig was made/purchased, due to the numerous running production mods. There have been a few reports of people being unable to "print" the BPSK telemetry, even though the signal is good, and the CW decodes well. Please reply off list. Alan WA4SCA

I'm having trouble getting telemetry. ARISSatTLM will see the signal on the Tuning Indicator and I have tuned the CW signal everywhere from the yellow mark to the top and bottom of the blue range. It decodes the CW fine in the Morse Code Decoder window but nothing ever shows up in the Telemetry As Text or ARISSatTLM main window. The orange indicator is following something, usually hanging around the middle of the orange line range when there is a signal. Any thoughts?

On the ARISSat-1 pass just ended here (23 degrees max elevation), results were about the same as yesterday. I heard my CW downlink for about a minute, peaking 559. Several other CW signals were in there, but I couldn't get their calls due to the deep fades. Bruce appears to be right that the transponder's performance depends largely on the spacecraft's orientation. 73 Ray W2RS

Tried to work the 1201Z 06AUG2011 pass of ARRISSat-1 from FM26 this morning without much luck. I have been successfully working the FM birds for a while but this is my first attempt with a linear bird. I was wandering if someone with a similar setup could verify my settings? Equipment as follows: Icom IC-910H Gulf Alpha 2M/70cm dual band yagi. 2M->6 element 70cm->8 element antenna LVB tracker box connected to a Yaesu G-5500 Az/El Rotator controlled by Ham Radio Deluxe. In HRD I set the following: Rx - Center of 145.930 USB Tx - Center of 435.750 LSB I set it to control doppler on *both* freqs. I am pulling the keps from Celestrak now. This morning's pass was to North->South and to the West of my location(FM26au). I noticed that the Rx was always being set lower than the center freq, and the Tx was lower before max elev and higher after Max elev. I had about a 9min window. About a 1/3 of the way into the pass I thought I heard some garbled voice. In the last 1/4 of the pass I definitely was hearing some CW. I can post the recorded .wav file if necessary. Would greatly appreciate any help. 73, Bill - W4RVN

RADIOSCAF-B Lemonade

This was a maximum 6 degree elevation pass for me. Six degrees. This, and reading Bruce's description of WB4SON's success with QRP leads me to ask, are we SURE there's not a 70cm antenna attached? Antenna or no, RADIOSCAF-B or whatever you wish to name it, I think this is a raging success of the platform. Congratulations to all involved. N8UX.

KP4WES voice as heard on Arissat-1
by (KP4TR)Ramon Gonzalez 06 Aug '11

06 Aug '11

Hello, Last night I was caught by surprise while listening to Arissat-1 over Puerto Rico the voice of a boy called Wesley (KP4WES). It was in Spanish, and now I found out he's the son of WP4T (Walter) who I know personally and have worked him on AO51. KP4WES is only 9 years old! Here's a video of what I captured last night while Arissat-1 was over Puerto Rico: http://www.youtube.com/watch?v=NKaAMw3yJz0

ARISSat-1 in Arizona @ 1332 UTC
by Patrick STODDARD 06 Aug '11

06 Aug '11

Hi! This was my first attempt on this satellite. CW telemetry at 145.920 was easy to copy, and I hear CW and SSB through the transponder. It wasn't hatd to hear the transponder after the satellite was up a few degrees from the horizon, and I heard my own CW near mid-pass. Maximum elevation here was 33 degrees. Above 20 or so degrees elevation, I could hear my CW. Near the midpoint, I briefly heard myself in SSB. Fading is there, but having to adjust my VFO more often than working VO52 makes this bird more of a challenge. Although I didn't complete a QSO, I think I heard KN6ZA in CW. I know I clearly heard AA5PK in SSB starting around 1337-1338 UTC. I will try again on the next pass at 1508-1517 UTC. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

ARISSat-1 over West Malaysia
by Sion Chow Q. C. (9W2QC) 06 Aug '11

06 Aug '11

Dear All, It was great to receive ARISSsat-1 over West Malaysia during 5th August 2011, 0223 UTC pass. Maximum elevation was 89 degrees. The downlink of both 145.919 MHz USB and 145.950 MHz FM was 59+60db, very strong but with huge QSB observed. A total of 3 SSTV pictures were forwarded to the ARISS SSTV gallery and some telemetry/Kursk data were forwarded by ARISSatTLM. Congratulations to all those involved with ARISSsat-1 and we look forward to trying out the transponder on the next pass. A few questions I have if someone could please help me clarify them: 1. Is it possible to have the callsign and forwarding telemetry option always set in ARISSsatTLM? This way, we do not have to manually enter the callsign and enable telemetry forwarding each time the program starts up. 2. Does the CW beacon needs to be really +/- 100 Hz of the yellow line? The reason for this is that I would like to see how much offset should I apply to doppler control, for possible automated reception. 3. In low power (eclipse) mode, how often does the BPSK1000 telemetry transmits? Thank you. 73, Sion Chow Q. C., 9M2CQC, Also: WQ2C /HL1, 9V1QC, JG1XHM ex: 9W2QC, AB3IO

ARISSat1/RADIOSCAF-B doppler in SatPC32 problem
by Richard Ferryman 06 Aug '11

06 Aug '11

I set up an entry in Doppler.sqf, originally as ISS and now as RADIOSCAF-B for the ARISSat1 CW and telemetry frequencies. SSB receive only so TX set to 0 MHz, step 20Hz. Unfortunately the doppler correction is not following the received frequency correctly. The rate of change is wrong so I lose lock on the telemetry decode after less than 1 minute. Any ideas as to what I have missed? Dick G4BBH

Simple preamp improvement
by andy thomas 05 Aug '11

05 Aug '11

I found that a homebrew single transistor untuned preamp (page 4.42 of the RSGB's VHF/UHF handbook) was sufficient to lift pictures out of the noise - thought the funcube developers might reflect on this , looks like it's an essential feature for the ground station. 73 de andy g0sfj

transponder at 4:00Z
by Bruce Robertson 05 Aug '11

05 Aug '11

I, and many others were able to get into the transponder at 4:00Z on August 6th. I used about 40w into a Lindenblad on TX and another omni on receive. One 'window' seemed much better for all of us than did the others, probably having something to do with the orientation of the RX antenna. I say this because the BPSK and FM signals were not very low in the other windows, whereas at the same time the linear band seemed quite less powerful. It's an amazing thrill to work our AMSAT SDX for the first time, and my sense is that any VO-52 class station should be able to hear its downlink. 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com

Wisat32 Question
by Sion Chow Q. C. 05 Aug '11

05 Aug '11

Dear All, I am trying to use Wisat32 for unattended automated satellite tracking and have some questions if anyone could help me clarify: 1. Is it possible for Wisat32 to run a normal .bat batch file say 20 seconds before AOS and 20 seconds after LOS? This is used for power on and off to the satellite equipment. Previously WISP used to be able to do this, but I do not see the settings in Wisat32. 2. Is there any setting to ignore passes below a predefined elevation, for example below 5 degrees. Thank you. 73, Sion Chow Q. C., 9M2CQC, Also: WQ2C /HL1, 9V1QC, JG1XHM, ex: 9W2QC, AB3IO

ARISSat-1 over Vietnam
by Vu Trong Thu 05 Aug '11

05 Aug '11

Hello everybody, I've just had my first try with ARISSat-1 this morning (max elevation 22 degrees), the CW2 signal is audible from AOS till LOS though the Morse Code Decoder had some trouble decoding the audio. Here's what I've got "ARIISATQ RS 1S NSPSI OET 327 M IH~30C CP +~3 C B~ 35N~TA IUHIS IEISSATL RST50E~VIET I5TS~UE+RT Q K", the rest is probably garbage as I tried to vary the LOCUT and HICUT of the SSB filter. I have a Kenwood TS-2000 transceiver, could anybody suggest optimal values for these settings? No BPSK frame was decoded, will try again! 73, Thu XV9AA

report of QRP ARISSAT-1 transponder operation
by Bruce Robertson 05 Aug '11

05 Aug '11

I thought the members of the list would be glad to read the following from Bob, WB4SON, written on the funcube list: "Guys I keep reading false rumors here about big-guns or high power needed to access ARISSAT. That is NOT correct. I had no issue hearing my signal on the downlink. I'm using omnidirectional low gain antennas (egg beaters) and 5 watts produced a S8 signal that was at least 5 S units above the noise. I have NO doubt 1 watt will produce a fine downlink signal What did or did not happen during the launch makes no difference now as it is working fantastically well Try it. Enjoy it. No worries!!!" 73, Bruce VE9QRP -- http://ve9qrp.blogspot.com

Arissat-1 Commanding?
by Burns Fisher 05 Aug '11

05 Aug '11

I saw on one of the NASA announcements that the snarffled 70cm antenna would mean no commanding of the bird. (This was probably before it was realized that that receive actually seems to work). But the question I have is whether there IS some commanding of the bird possible. I guess you have to be able to turn it off to satisfy the FCC (true?) but can other things be done? I assume/home that the command channel is encrypted, so disclosing its existance is not compromising the bird. 73, Burns W2BFJ

ARRISSat-1 Report and Thanks
by Nitin Muttin 05 Aug '11

05 Aug '11

It was a great pleasure to watch the deployment of the ARRISSat-1 from the ISS on NASA TV. On behalf of AMSAT INDIA I would like to thank all at AMSAT , ARRISSat project team for enabling this capability for the Amateur Radio fraternity. I was able to hear the signals on 145.950 during the 03:57 UTC on 08/5/2011 over India and decoded a SSTV image and heard the CW on 145.919 but was unable to decode the telemetry using ARISSATLM application. Will try again to decode the telemetry and also the linear transponder. Many Radio Hams in Bangalore have reported hearing the signals on 145.950. The image can be found at http://vu3tyg.addr.com/ARRISSAT/Arissat.jpg The recording of the voice message, SSTV and CW can be heard at http://vu3tyg.addr.com/ARRISSAT/rec0805-092348.mp3 73's Nitin [VU3TYG] Secretary, AMSAT INDIA

NASA Accepting CubeSat Proposals
by Clint Bradford 05 Aug '11

05 Aug '11

August 05, 2011 Joshua Buck Headquarters, Washington 202-358-1100 jbuck(a)nasa.gov RELEASE: 11-256 NASA ANNOUNCES NEXT OPPORTUNITY FOR CUBESAT SPACE MISSIONS WASHINGTON -- NASA is seeking proposals for small satellite payloads to fly on rockets planned to launch between 2012 and 2014. These miniature spacecraft, known as CubeSats, could be auxiliary payload on previously planned missions. CubeSats are a class of research spacecraft called nanosatellites. The cube-shaped satellites are approximately four inches long, have a volume of about one quart and weigh less than three pounds. Proposed CubeSat investigations must be consistent with NASA's Strategic Plan and the Education Strategic Coordination Framework. The research should address aspects of science, exploration, technology development, education or operations. Applicants must submit proposals electronically by 4:30 p.m. EST on Nov. 14. NASA will select the payloads by Jan. 30, 2012. Selection does not guarantee a launch opportunity. The selected spacecraft will be eligible for flight after final negotiations when a launch opportunity arises. NASA will not provide funding for the development of the small satellites. NASA recently announced the results from the second round of the CubeSat Launch Initiative. From the first two launch initiatives, 32 payloads made the short-list for launch opportunities in 2011 and 2012. They are eligible for launch pending an appropriate opportunity and final negotiations. The satellites come from 18 states: Alabama, Alaska, California, Colorado, Hawaii, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Missouri, Montana, New Hampshire, New Mexico, New York, Pennsylvania, Utah and Virginia.

ARISSat-1 WAV file
by Edwin M. "EMike" McCardel, KC8YLD 05 Aug '11

05 Aug '11

I made this recording this morning from EN80um beginning Approx. 1124 UTC http://www.kc8yld.com/arissat.wav Recording was made on an Olympus handheld digital recorder. My equipment was Wouxan handheld and Arrow Antenna. I had my Yaesu VX-8R equiped with a rubber duck antenna laying on the ground. Near the closest approach I could also hear the transmission through it. Load enough at times I turned down its volume so not to interfere with my recording. >From the recording I was able to decode the SSTV transmissions using the SSTV app on my iPad (I didn't think of trying this direct in the field) these images are at http://www.kc8yld.com/5Aug2011-1126.png http://www.kc8yld.com/5Aug2011-1128.png<http://www.kc8yld.com/5Aug2011-1126.png> http://www.kc8yld.com/5Aug2011-1130.png<http://www.kc8yld.com/5Aug2011-1126.png> EMike, KC8YLD E.
