During the 1520Z pass, one of the cosmonauts came on 145.800 and reported that he was copying everyone fine on the space station. Then there was a pause followed by a steady unmodulated carrier. I guess they haven't figured out what's wrong yet. Glenn AA5PK

Planned SSTV. Testing from ISS ???
by David 18 Jul '15

18 Jul '15

Hello all: This is David EA4SG from Madrid Spain. Just listening on 145.800 for the planned SSTV transmission, just some minutes ago at 10:53 UTC I copied a very strong intermitent signal coming from the ISS direction. I call the ISS telling them that I was listening and offering my help if needed and one of the two russians cosmonauts took the microphone and answered to my call. After the report I asked if they are going to send SSTV and he told me that they will be sending the pictures the whole day. Then he QRT. Very happy for my voice QSO with RS0ISS. 3 minutes later and until LOS a long carrier, strong signal but no modulation at all. Carrier was there until LOS so I could not had the chance to inform them that the expected SSTV modulation was missing. Just for your information. 73s David EA4SG

FUNcube-1 operations
by Graham Shirville 17 Jul '15

17 Jul '15

Good evening, Just to report that FUNcube-1 is now in continuous “transponder on” mode for the weekend. It can be expected that, as usual, she will stay in this mode until Sunday evening (UTC time) A heads up for next weekend – As AMSAT-UK is holding their Collloquium event in Guildford Surrey, it is expected that FUNcube-1 will be switched to continuous transponder mode , exceptionally, from Thursday evening (July 23rd) until either Sunday evening (July 26th) or, more likely, Monday evening (July 27th). This will enable the Colloquium attendees to view or demonstrate and enjoy the transponder operations for the maximum possible time. Thanks for your understanding! best 73 Graham G3VZV

Re: [amsat-bb] PSAT PSK31 experimental software (Op ideas)
by Robert Bruninga 16 Jul '15

16 Jul '15

Full DUX PSK31 Operating ideas: Can I assume the TX uplink software has the usual BRAG text and CQ features, since the expectation is that users will continuously transmit throughtout the entire pass and the operator has plenty to do other than type continuously at the keyboard. So I envision some continuously running brag text including CQ's the call, the HF antenna, the power, the grid, the location in DDN/DDDW whole degrees maybe (for APRS purposes), the downlink antenna, and so forth. And then maybe the looping uplink will stop at the next item separator and allow the operator to inject keyboard text. In other words, the loop just runs. But if the operator begins typing (maybe he sees a buddy in the dowonlink) he just starts typing and the LOOP stops at the next break in loop elements and inserts the typed text. Im thinking that elements in the brag string would be separated by " - " but then when ever the operator types text, then it is inserted in the stream beginning with [ then text goes here and ends with a ] when he hits the enter key? By having a common system of continuous brag items and interjected live text, then we all have consistent expectations as to what the PC is doing versus the operator?

My packet setup gets digipeated instantly on terrestrial APRS networks, and works fine with ARISS, but even with overhead passes on NO-44 and NO-84, when I copy the birds well, I can't manage to get an APRS packet digipeated. Even if I crank the power up to 50 watts, using the M2 LEOpack antennas, those birds simply are deaf to me. I'm sending to CQ via ARISS, as my reading of the online docs seems to indicate that is appropriate. I've also tried CQ via PCSAT-1 and CQ via PSAT (for NO-84) but still no joy. I've also played with TX delay. Nothing works. What am I doing wrong? -- Mark D.

Arizona, except for the portion of the Navajo Nation reservation in the northeastern part of the state, does not change its clocks for daylight time in the summer. It's UTC -7 hours for local time, all the time. We really don't need the extra hour of daylight, when it is so hot in the deserts during the summer. Looking forward to this video presentation, and to hear the ISS as it passes over. W7LB is the ground station for this contact, and Larry Brown is a long-time AMSAT member and supporter.

Tips for posting time-sensitive messages
by Alan 15 Jul '15

15 Jul '15

Hi, People sometimes post time-sensitive messages to AMSAT-BB and SAREX. Examples are last minute grid activations, unexpected satellite mode commands, requests for critical telemetry after a launch, etc. These normally go through promptly, but occasionally get held for two primary reasons: While AMSAT-BB and SAREX are both open lists, that means they are open for membership. In order to post to the list, it normally must be from the same account you originally registered. For instance, if you registered from your home account, and post from your office account, it will normally be held for release by a moderator. Likewise, some people have all their email forwarded to a single account from which they reply. We can easily create a filter to pass the second address, but that is not automatically done on the first posting, and does require moderator action. Both mailing lists receive literally dozens of pieces of spam for each legitimate message. As part of the filtering process, emails larger than 40-50kB are blocked. This usually happens to legitimate email when someone attempts to attach a large file, or replies to a long message without trimming. These also require moderator intervention, and are normally not approved but bounced back to the originator for adjustment. Also, there is a limit to the number of addresses before an email is held as potential spam. I have seen legitimate email sent to 20+ addresses. We have a team of volunteer moderators, but they are not available 24/7. The result is that a message sent in the evening or on a holiday, US time, may well be held for 10-12 hours before being released. So, if it absolutely, positively needs to be distributed promptly: 1. Post from the same account you registered for, or one which from past experience you know has been flagged as acceptable. 2. Post a message less than 40 kB, with no attachments which will always be stopped. (Pictures should be included by a link.) 3. Send it to AMSAT-BB, SAREX, and a few other addresses a most. If you must send to a large distribution list, send to them, and another copy to the AMSAT lists. 4. Consider also posting to the AMSAT Twitter and Facebook accounts. There is overlap in membership, though at present it is far from 100%. 73s, Alan WA4SCA

APRS Satgate Omni Antennas
by Robert Bruninga 15 Jul '15

15 Jul '15

Finally did some PSAT tests with 1/4 wave on car roof and TH-D72 Kenwood radio. * On a 60 deg pass I heard 25 packets decoded one at 5 bars. * On 21 degree pass heard 5 packets but none above 1 bar. * On 40 degree pass heard 37 packets decoded 5 when they hit 5 bars. Also got in with 5W. * on 40 deg pass (in Annapolis) heard a single 5 bar packet and no decode. NOTICE, the first three were at the beach with no real planning as to building obstructions. But apparently the noise open squelch was S0. But in Annapolis, after hearing nothing (1 packet) I opened the squelch to see a full 3 bars of noise. Remember, the radio ALWAYS shows ZERO S units until the squelch actually opens, so the presence of even S9 broadband noise will show nothing and HEAR nothing unless you open the squelch manually! The Baghigawatt area defense radar on 149 MHz in the DC area was operating at the time. Again, shows the value of having any SATGATE OMNI antnenna on the ground well below horizon (and only able to see sky above 30 deg)... P.S. On this 19" magmount whip, the 435.350 PSK31 came in FINE! Remember this is a 3/4 wave vertical on UHF. So to pick up the needed 3dB more on VHF, the next tests should use a 3/4 wave at VHF or about 58 inches... Much more testing needed. de WB4aPR, Bob ------------------------ original message ---------------------- Some EZNEC models: 1/4 wave with radials: -2 at 30 and -6 at 60 ==> Basically a dipole pattern 3/4 wave with radials: +2 at 30 and -1 at 60 ==> 4 to 5 dB better, 2 dBi max 3/4 wave w 3' gndpln: +3 at 30 and +1 at 60 ==> 5 to 7 dB better, 3.3 dBi max 3/4 wave w 6' gndpln: +2 at 30 and +3 at 70 ==> 4 to 9 dB better, 5.5 dBi max 3/4 wave w 9' gndpln: +3 at 30 and +3 at 65 ==> 5 to 9 dB better,5.3 dBi max 3/4 wave perfect gnd: +3 at 30 and +3 at 68 ==> 5 to 9 dB better, 6.9 dBi max Even the 3/4 with just the four 19" radials gives a huge 4 to 5 dB improvement over a classic ground plane for omni satellite SATgate work. Also, this antenna does not need to be high. Just see sky above 30 deg. In fact, is better to be low to reduce terrestrial QRM. Notice too that the Lilenblatt, eggbeaters, and all other "omni"s that try to keep their gain down on the horizon, are equally as poor as the 1/4 wave vertical at these higher elevations. This is OK for strong satellits like the ISS with 5 to 10 watts, but abisimal when all that gain on the horizon is completely wasted when you cannot hear the satellite anyway because it is 6 to 10 dB farther away! The result is these "omni's" give up the 4 to 9 dB at higher elevations where the satellite is much stronger. See the Omni SATGATE page: http://aprs.org/aprs-satellite-igate-antennas.html Summary: The 3/4 wave vertical should make it so you CAN hear weak LEO satellites 5 to 9 dB better when they are closer and does this by giving up on hearing them when they are so far away you can't hear them anyway! Bob, WB4APR -----Original Message----- From: Robert Bruninga [mailto:[email protected]] Subject: RE: [aprssig] APRS Satgate Antenna page > One question,what constitutes a large ground plane? > Is it 12"or 12'? Is it a multiple of the vertical whip? Good question. Most people think that four 1/4 wave radials make a ground plane. But if you model a 1/4 wave vertical over 1/4 wave radials, all you get is the exact pattern of a DIPOLE. The radials are just providing a "groundplane" to complete the electrical part of the antenna and give a good match. They do not affect the pattern at all. I modeled verticals over 6' or larger ground planes and only found that you get the added "reflection" gain when the ground plane starts getting that big or more. I wish I had time to use EZNEC to show the added gain (skyward) versus the size of the ground plane. And how "radials" (above actual ground) have nothing to do with the "pattern". SO, the bigger the better. It should be worth 2 to 3 dB if you could make it very large...

remote sat ops
by kb2m＠arrl.net 14 Jul '15

14 Jul '15

Is anyone using TeamViewer (or any other remote PC control s/w) to control their sat station remotely? I'm able to run SatPC32 remotely to control my Yaesu rotor, LVBTracker, 9100 sat system. Thanks to Erich I can view the actual and target az el position of the rotor with a version of serverSDX. I'm looking for a s/w program to remotely control radio functions like PTT, and also handle rx/tx audio. I will be heading back to Florida for the winter in October so I have plenty of time to set this up. I also have a small shore home that is 60 miles away to test from as I go down there every week for a few days. Any suggestions from experienced remote sat ops before I start looking? 73 Jeff kb2m

Delfi-C3 server migration - setting change for RASCAL client
by wouter weggelaar 14 Jul '15

14 Jul '15

Hi All, Due to security and maintenance reasons we will have to migrate the Delfi-C3 telemetry server to a new environment. Unfortunately the IP address will change, so server settings in RASCAL need to be updated. The transition will take place during the 8th of July. On this day both servers will not be offline for 4 -8 hours to be able to migrate the databases. The local repository of the RASCAL telemetry client frames should be sufficient to avoid data loss for the downtime. Our advice is to add the new server as primary/secondary server before the 8th and remove the old server after the 8th of July. New IP: 131.180.122.144 Port: 1099 In case plans change or things do not go as expected, we will notify you as soon as possible. Delfi-C3 is doing great. We have long exceeded the design lifetime of the satellite and she continues to work great. We appreciate your help in acquiring data of Delfi-C3 and hope that you continue to track our “old” bird in the future as well! Best regards on behalf of the team, Wouter Weggelaar Delfi-C3 ops team

ISS SSTV Project This Weekend
by Clint Bradford 14 Jul '15

14 Jul '15

Capturing these wonderful images can be as simple as using an HT programmed to 145.800, a simple homebrew antenna improvement (like a tape measure beam), and a great $3 iOS app from Black Cat Systems entitled “SSTV Slow Scan TV”. https://itunes.apple.com/gb/app/sstv/id387910013 With this meager setup, receiving SSTV images from the ISS was really simple! I merely held my iPod touch near my HT’s speaker, and obtained clean graphics immediately. This app also works on iPhones and iPads. SO ... ANOTHER aspect of this wonderful hobby that one can get in to without spending a lot of money! Here's an article from AMSAT-UK with more software/hardware suggestions ... http://amsat-uk.org/2015/03/31/iss-sstv/ Clint K6LCS

My problem with rotor control using ver C.
by Douglas Phelps 14 Jul '15

14 Jul '15

I figured out the problem thanks to an Email sent to me by Erich. It had been so many years since I loaded a new version of SatPC 32 that I had forgotten that I had to setup the port in Easycom as well as in StaPC 32. I want to publicly acknowledge the private work Erich does to help SatPC 32 users. It is another reason why I think SatPC 32 is the best choice in satellite software. Thanks Erich. DougK9DLP

ARISS SSTV Images to Commmemorate 40th Anniversary of the Apollo-Soyuz Mission
by Frank Bauer 14 Jul '15

14 Jul '15

40 years ago this week, the historic joint Apollo-Soyuz mission was conducted. Apollo-Soyuz (or Soyuz-Apollo in Russia) represented the first joint USA-Soviet mission and set the stage for follow-on Russia-USA space collaboration on the Space Shuttle, Mir Space Station and the International Space Station. The Soyuz and Apollo vehicles were docked from July 17-19, 1975, during which time joint experiments and activities were accomplished with the 3 USA astronauts and 2 Soviet Cosmonauts on-board. Apollo-Soyuz was the final mission of the Apollo program and the last USA human spaceflight mission until the first space shuttle mission in 1981. To commemorate the 40th anniversary of this historic international event, the ARISS team has developed a series of 12 Slow Scan Television (SSTV) images that will be sent down for reception by schools, educational organizations and ham radio operators, worldwide. The SSTV images are planned to start sometime Saturday morning, July 18 and run through Sunday July 19. These dates are tentative and are subject to change. The SSTV images can be received on 145.80 MHz and displayed using several different SSTV computer programs that are available on the internet. We encourage you to submit your best received SSTV images to: http://spaceflightsoftware.com/ARISS_SSTV/submit.php The ARISS SSTV image gallery will post the best SSTV images received from this event at: http://spaceflightsoftware.com/ARISS_SSTV/index.php Also, as a special treat, on Saturday July 18 the ISS Cosmonauts will take time out to conduct an ARISS contact with students attending the Moon Day/Frontiers of Flight Museum event in Dallas Texas. This Russian Cosmonaut-USA Student contact is planned to start around 16:55 UTC through the W6SRJ ground station located in Santa Rosa, California. ARISS will use the 145.80 MHz voice frequency downlink (same as the SSTV downlink) for the Moon Day contact. For more information on ARISS, please go to our web site: www.ariss.org The ARISS international team would like to thank our ARISS-Russia colleague, Sergey Samburov, RV3DR, for his leadership on this historic commemoration.

Golden Packet gaps at SamsPT NY and Mt Equinox in VT.
by Robert Bruninga 14 Jul '15

14 Jul '15

For Saturday's 6th annual golden packet event from Georgia to Maine we still have 2 gaps. One at Sam's PT NY and the other on Mt Equinox in VT. This is a 4 hour event starting at noon. Sam's point is a walk-up so the ideal radio is a Kenwood TH-D72 HT (it digipeats), but Equinox is a driveup. I ask here on AMSAT, because many portable satellite operators have these radios. See http://aprs.org/at-golden-packet.html If we are unable to close those links, then we will open the channel up to any other mountain topers or APRS hikers anywhere on the east coast to join the channel. Be sure to let us know for planning. Bob, WB4APR

SO-50 timer
by Kevin M 14 Jul '15

14 Jul '15

A question was recently asked in a popular ham forum about resetting the 10 minute timer on SO-50 and the results showed some ignorance concerning exactly how the timer operates. It is not like a terrestrial FM repeater... the timer is not affected by the amount of 'on air' activity. It WILL shut the repeater off ten minutes after it was last reset. It does not matter where over the planet it is at the time. It will shut off in the middle of a busy pass, even in the middle of someone's transmission. The only thing that resets it, is transmitting the proper 74.4 Hz reset tone. And keep in mind, it will not retransmit your signal while sending the 74.4 Hz tone... it will transmit again the next time it receives a signal with the 67 Hz tone. This is important information, even for beginning operators to be aware of, because when the timer needs to be reset, it needs to receive a clear signal. If stations of equal strength keep trying to transmit at the same time as a station trying to reset the timer, signals will collide and the satellite will not receive the reset tone. I suppose it's a crap shoot as to who should or will reset the timer, but if in doubt, err on the side of caution and stop transmitting. Especially if you are have a minimally powered station such as an HT. Unless of course, it's a late night pass and you are the only one on. =^) I just wanted to get this information out there so new satellite operators are educated properly. Proper understanding is key to effectively using a shared resource such as a satellite repeater/transponder. And that goes for new and experienced operators alike... =^) 73, Kevin N4UFO

Sat PC32 version C
by Douglas Phelps 13 Jul '15

13 Jul '15

Does anyone have a fix for this problem, I have used SAT PC32 ver A for years with no problem, I use the ST-1 rotor interface abd the rotor setup is set to SABERTrack. This arrangement works perfectly. For Fieldday, I upgraded to SAT PC32 ver C and the rotor stopped working. I used the same rotor setup as ver A. I loaded SAT PC32 on another computer and it also would not work with the rotor. Basically, Everything worked with version A but not with ver C using the same rotor setting. Any Ideas?

If anyone wants to try AO7 at 2115 UTC, please tweet me (@WD9EWK) or e-mail me soon. I still have 2.5 to 3 hours to drive, but will give AO7 a try - if it is in mode B. 73!

DX on AO-7B
by Bob- W7LRD 13 Jul '15

13 Jul '15

Hello from Seattle, Wa I brought this up before and it had little to no traction. I can very occasionally work into N. Eu. with very little time available. I suggest we unofficially designate a "watering hole" frequency for DX efforts. We had this on AO-40 sobsob) and it worked pretty good. I suggest 145.947 for this effort. Either cw or SSB. Most likely CW as signals are marginal at low elevations. With little time available it will easier to find and make these contacts. I have not heard Mika OH8MBN for awhile or few other N.Eu. stations. So you Gents across the pond at near your LOS try 145.947. You can put a note on this bb for a heads up warning. 73 Bob W7LRD CN87 Seattle Wa.

Satellite Activity LOGs
by Pedro Converso 13 Jul '15

13 Jul '15

Hello, I see many entries on Amsat-bb showing just yourself aboard a satellite. A while ago, we have implemented in South America a web page that helps people get in touch through the birds. It is easy to log a contact and allows other people to see where and when activity is or will be. It also sends email to log reporters of last activity entry, also allows contact each other for a particular log. Although it is in Spanish, think you can see how easy and straightforward it is, just one screen and no previous registering. This function helped since availability to quite increase South America satellite activity. You can see online at http://lu7aa.org.ar/log.html or http://amsat.org.ar?f=z Perhaps an application like this in Amsat-NA could help avoid unpopulated passes in your area. 73, lu7abf, Pedro Converso Buenos Aires, Argentina www.amsat.org.ar

Re: [amsat-bb] EB-144 High SWR going crazy
by Dino Papas 13 Jul '15

13 Jul '15

Lee - did you take the center assembly apart? My original EB-144 had a failed connection at the coax connector center pin inside the antenna center assembly which initially appeared as an intermittent depending on the torque applied when attaching the feed line. That connection is difficult to repair as you have to desolder the short piece of feed line from the balun PCB and then remove the connector from the body; I was able to do it and M2 to their credit replaced mine very quickly as the eggbeater was to be our ARISS contact backup antenna only a few days later (the fault showed up at the ARISS site when setting up). If this is the case with yours send me a note and I’ll forward the pix I took of the inside the body of the center assembly. 73 - Dino KL0S On Jul122015, at 2349 PM, Lee Maisel <maisel(a)lobo.net> wrote: > Hello, > > I have an M2 EB-144 eggbeater, and am going crazy trying to figure out why I get high SWR and it is not working. > > I replaced all cable with LMR-400 (about a 50' run) and new solder on N connectors, and tested them, but no matter what I get horrible high SWR. > > I redid the ends, I took the whole antenna down, took it apart, checked and redid all connections, hooked it up to the radio in the shack, NO high SWR..

EB-144 High SWR going crazy
by Lee Maisel 13 Jul '15

13 Jul '15

Hello, I have an M2 EB-144 eggbeater, and am going crazy trying to figure out why I get high SWR and it is not working. I replaced all cable with LMR-400 (about a 50' run) and new solder on N connectors, and tested them, but no matter what I get horrible high SWR. I redid the ends, I took the whole antenna down, took it apart, checked and redid all connections, hooked it up to the radio in the shack, NO high SWR.. Took it back up installed on the roof, and same old horrible high SWR. Any clue what the problem could be? Thanks!

CM94/CM95 this afternoon
by Patrick STODDARD (WD9EWK/VA7EWK) 12 Jul '15

12 Jul '15

Hi! I will work some passes from the CM94sx/CM95sa grid boundary near Santa Maria CA this afternoon. At 2100 UTC, I will be on SO50, then will try to work passes through the 0035 UTC FO29 pass. I may try for some evening passes, depending on how I feel. I have a 500-mile drive tomorrow, and need to get out of here early (and also reach DM23/DM24 in Arizona for at least a pass or two). I will also try the 2040 UTC ISS pass over the west coast, if anyone out here wants to try for a packet QSO on this line. Still using Twitter to post updates, and photos too. More to come this afternoon. Use this link if you aren't a Twitter user: http://twitter.com/WD9EWK 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/ Twitter: @WD9EWK

The beautiful coin will be a keepsake to treasure. The ARISS program relies on resource support from NASA, ARRL, AMSAT, and individual donors to ensure continuing the day-to-day operations and communications, and to pay for space-flight certification of equipment. Current finances to sustain operations in future years are insufficient. The ARISS program is initiating a fundraising campaign with the goal of securing greater financial stability for the program. According to ARISS International Chair Frank Bauer, KA3HDO, “To assure the future of the program we are looking to individuals and corporate sponsors to provide the resources we will need to sustain operations and to acquire needed equipment upgrades.” Plans are underway to develop a new higher power Amateur Radio station for the ISS Columbus module. The current radio is a lower power unit that sometimes results in weak signals. A new radio system will improve the communications for education groups whose students are scheduled for ARISS contacts and related educational activities. The new system will also allow greater interoperability between the Columbus Module and the Russian Service Module. Integration of the equipment into the ISS infrastructure and required testing and certification require hours of engineering resources that ARISS must pay for and cannot afford. Each ARISS contact offers the opportunity to inspire young people through ARISS’ unique window into space exploration activities, opening the horizon of possibilities of a career in a STEM field. Each contact also introduces students and their communities to Amateur Radio—all positives for Amateur Radio and our country and world. ARISS needs your help to secure these opportunities for the future. Individuals may make donations to ARISS online at www.amsat.org by selecting the “Donate ARISS” button. (AMSAT-NA will provide people resources to handle your gifts to ARISS.) Individuals contributing $100 US or more will receive the brand new ARISS Challenge Coin. Corporate donors may contact Frank Bauer at KA3HDO(a)verizon.net or ARISS(a)arrl.org. [ANS thanks ARISS for the above information] --------------------------------------------------------------------- Delfi-C3 RASCAL Update Necessary for New Server IP Address Wouter Weggelaar, PA3WEG, reported this week that due to security and maintenance reasons the Delfi-C3 team had to migrate the Delfi-C3 telemetry server to a new environment. This change also required that the IP address for uploading data needed to change. This means your server settings in RASCAL need to be updated to: New IP: 131.180.122.144 Port: 1099 On July 9 Wouter reported, "The migration has been completed almost without a problem. We still have some minor issues to sort out. Telemetry submission is operating normally but the database performance seems slow. This makes processing more difficult on our end. New user accounts cannot be created but new users can successfully submit received data via the 'guest' account." The team reports that Delfi-C3 is doing great. They have long exceeded the design lifetime of the satellite and she continues to work well. They appreciate your help in acquiring data of Delfi-C3 and hope that you continue to track their "old" bird in the future as well! [ANS thanks Wouter Weggelaar, PA3WEG and the Delfi-C3 team for the above information] --------------------------------------------------------------------- CAMSAT Launch Postponement A launch postponement has been announced for Beijing’s new CZ-6 rocket which is planned to carry a constellation of amateur radio satellites. Soon to be launched six CAMSAT satellites CAS-3A to F have now been named as XW-2 (Hope-2) amateur satellite system, and correspond to the XW-2A to F. All the satellites have completed environmental testing, currently being burn-in tests, everything is underway. The satellites will be moved to the launch center in mid-August and launch date has been postponed to early September. [ANS thanks Alan, BA1DU, for the above information] /EX In addition to regular membership, AMSAT offers membership in the President's Club. Members of the President's Club, as sustaining donors to AMSAT Project Funds, will be eligible to receive addi- tional benefits. Application forms are available from the AMSAT Office. Primary and secondary school students are eligible for membership at one-half the standard yearly rate. Post-secondary school students enrolled in at least half time status shall be eligible for the stu- dent rate for a maximum of 6 post-secondary years in this status.

DeorbitSat - Warbler vs SoundModem comparison
by Ken Swaggart 11 Jul '15

11 Jul '15

During the 1940Z pass, 7 degrees max elevation over the Pacific, I ran both Warbler and SoundModem ver 0.83b. SoundModem captured slightly more than twice the frames that Warbler captured ( 14 vs 6). I did have to un-tick the non-AX.25 filter option in the SoundModem settings for BPSK AX.25 1200 baud. Thanks to all the responses to my BPSK demodulator query. 73, Ken, W7KKE

Is it possible to us both SatPC32 & Dx Labs-Suite with IC910H ?
by Bob KD7YZ 11 Jul '15

11 Jul '15

Before I give up and sell any Sat gear I have, I thought I'd ask if there is anyone USING an IC910H, SatPC32 and also reading/logging the UpLink and DownLink frequencies with DxLabs Commander. For many. many months I have wasted countless hours trying to get that combination to work together. SatPc32 with flawlessly control the rotors and the IC910H. DxLabs Suite Commander will pretty-well control the IC910H. If I try to use VSP Manager or Virtual Serial Port emulator to allow both controlling programs to use the IC910H, it simply will not function. Thus if I want to work the Sats, after each QSO I have to write down the uplink and downlink QRG , times, and such, so I can later log the QSO by typing it into the computer. It's a bit overwhelming to log when I often get a few calls for a semi-rare State, Kentucky. I seriously could use some help to set these programs to make the IC910H play the game. thanks (hopefully) 73, -- Bob KD7YZ http://www.qrz.com/db/kd7yz AMSAT LM#901

Field Day Submissions
by Bruce 09 Jul '15

09 Jul '15

For those of you that only worked one or two stations on the satellite or if you worked 10, 20, 50 or more stations, please still submit your scores for Field Day. Although the form online at http://www.amsat.org (click on the Events tab and then the Field Day link) is in PDF format, you can copy and paste the submission portion into Word (amazing how they migrate back and forth). Or you can download the DOCX file from me at http://www.amsatnet.com/fd2015.docx Please remember that ARRL submissions are due much later than our submission date. I must have your submission received by 11:59 PM Central Time on July 13, 2015 (Monday). I then have less than a week to tabulate and write the article for the journal. Please include any pictures that will show off your field day site. We have had flamingos, long horn steers, clocks running on lemons, campers, ladder towers and all kinds of neat stuff in the past. I will confirm that I have received your submission, usually sometime that day. If you do not hear from me, please send to my other email address, or send to both at the same time. kk5do(a)arrl.net kk5do(a)amsat.org 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

Sig I saw KC9LU calling CQ via PSAT tonight on the PSK-31 transpodner and also saw a W2EV “robot” probably terrestrial. Thanks for the antenna info. Bob, WB4APR *----- original message ---------* UP-Date, Excited now! Tried Rubber ducky inside,,, Nothing Rubber ducky outside, nothing 1/4 wave 2 meter GP but on the 70 cm freq inside, squelch breaks. 1/4 wave 2 meter GP but on the 70 cm freq outside started hearing it 2 min into the pass, had to use doppler 5 hogh for a while then spot on then later 5 low. heard at least two stations in there and I'm guessing the telemetry? it is a quite low tone in there. but even with that heard it pretty well. I may make a simple antenna that is more or less omni. and add the arr pre amp, got any plans for such an antenna?

The TBAT first term should be -2.57E-6 not -2.5E-6… I crrected it below. They are now on the web page. Bob The first value is battery volts in hundredths. The second is bus power in mA. The third and 4th are +Z and -Z temps using the equation-1.26E-6*X^3 +0.0028 X^2 -2.215X +625. The last one is meaningless when the digi is ON. When the digi is off, then the last one is battery temp -2.57E-6* X^3 +0.0061X^2 -5.149X^+1475. In the 00011X00 value only the X has meaning. It is 0 if the digi is ON and it is 1 if the digi is OFF. Bob, WB4APR I was wondering more about decoding the telemetry values in a line like this that can be received on the two meter downlink: 00:00:18:41 : PSAT]APRSON,ARISS,qAR,W7KKE:T#515,854,075,502,862,410,00011000 In the original paper I found on the internet from 2007, the equations for decoding the values were "TBD".

Re: [amsat-bb] Fox, "Easy Sats" - segway to PSAT PSK31? (X 2)
by Robert Bruninga 08 Jul '15

08 Jul '15

Don't forget we actually launched TWO identical 10m PSK31 uplink and UHF FM downlink transponders (Built by Brno Univ). SO if you go for PSAT, be sure to set up 7 minutes earlier in case BRICSAT comes up too. BRICSAT has the same PSK31 transponder and appears to be 7 minutes ahead of PSAT. I just heard it at 2211z. It is power starved, however and only comes up now and then when its battery accumulates enough juice. And of course, neither comes up unless there are users in the 10m 28.120 MHz passband. -----Original Message----- From: Robert Bruninga [mailto:[email protected]] Subject: Fox, "Easy Sats" - segway to PSAT PSK31? Segway this argument to the 10m uplink now 100% available on PSAT PSK-31 which virtually no one is using. > With OSCAR 6 and 7... ten meter downlinks, it was just a matter of adding two meter transmit capability to an HF station.

Brief NO-84 RX with Omni Antenna
by Scott 08 Jul '15

08 Jul '15

Greetings all. Orbitron showed NO-84 passing directly overhead here in Virginia tonight, so against all odds I stuck the 5/8 mag. mount antenna parallel to the ground and perpendicular to the predicted track. I'm hesitant to bore the group but thought it was noteworthy that even with such a modest setup, I received a couple of packets (one with data; one incomplete). In fact, believe it or not, I had an FT-60 handheld laying on the coffee table that also broke squelch when I saw the two incoming packets on the computer screen via my Icom-28A. I thought that was pretty amazing as well, considering the low-power source. Here are the received packets: (timestamps are UTC on 8-July-2015) ----------------------------------------------------------------------------------------------------- Fm K0KOC-7 To APWW10 Via PSAT,ARISS* <UI pid=F0 Len=45 >[04:31:27] @043126h3923.18N/07724.92WlAPRS-IS for Win32 Fm W9QO To STPX1V Via PSAT,ARISS*,SGATE,WIDE2-2 <UI pid=F0 Len=11 >[04:31:37] 'oIPl -/] ----------------------------------------------------------------------------------------------------- 73, -Scott, K4KDR Montpelier, VA USA

Chinese amateur satellites - Launch delay
by David G0MRF 07 Jul '15

07 Jul '15

Hi all. I see Spaceflightnow.com have announced a delay to the amateur satellites initially due to fly on the 20th July I was searching around for the up and downlink frequencies for the transponder, but instead found this: Long March 6 • Multi-payload Launch time: TBD Launch site: Taiyuan, China A Chinese Long March 6 rocket will launch with a cluster of small Chinese amateur and university research satellites. The flight will mark the first launch of the Long March 6, a new rocket fueled by kerosene and liquid oxygen to replace China’s previous generation of launch vehicles. Delayed from July 20. [July 6] It suggests the new launch date will be in September. 73 David G0MRF

The show can viewed at W5KUB.com (http://w5kub.us10.list-manage.com/track/click?u=0d5cdae05233f79e11025a75d&i…) or heard on shortwave radio station, WTWW on 5085 KHz. Tom Medlin, W5KUB, is joined by co-host Ted Randall, WB8PUM, from the QSO Radio Show. The show covers a wide range of topics for ham radio operators, shortwave listeners, and electronic hobbyists; including balloon launches, Satellite, go-kits, emergency communications, SDR, digital modes, DXing, home brewing, and more. During last week's show, there was a major U.S. internet routing problem and outage which affected our show. Due to this outage we were unable to proceed our show and it has been rescheduled for Tuesday, July 6th. This week’s guest will be Clint Bradford, K6LCS. Clint lives in Southern California, and, by last count, has performed his "How to Work Amateur Radio Satellites With Your HT" presentation almost 80 times at conventions and clubs across the United States. To learn working the "birds" with just a simple HT, tune in Tuesday night's show. Clint will also discuss other tools needed; such as, free tracking software, how to home-brew a simple Yagi antenna for more punch in the signal, and the simple protocol used when making these fun and interesting contacts. In addition to learning about the satellites, the same equipment is used to contact the International Space Station. Clint also coordinated a school contact with the International Space Station - enabling students to interview an astronaut as the International Space Station streaked overhead. Clint's websites are work-sat.com (http://w5kub.us10.list-manage.com/track/click?u=0d5cdae05233f79e11025a75d&i…) and K6LCS.com (http://w5kub.us10.list-manage2.com/track/click?u=0d5cdae05233f79e11025a75d&…) We are adding a segment to the show at allows our viewers and listeners to call in to a phone line and be on the show.
