ANS publishes news related to Amateur Radio in Space including reports on the activities of a worldwide group of Amateur Radio operators who share an active interest in designing, building, launching and communicating through analog and digital Amateur Radio satellites. The news feed on http://www.amsat.org publishes news of Amateur Radio in Space as soon as our volunteers can post it. Please send any amateur satellite news or reports to: ans-editor at amsat.org. In this edition: * Fox-1A Mated to the Centaur for Launch * AMSAT 2015 Symposium Papers * PCSAT Default Beacon Transmissions on 144.390 MHz * 2015 AMSAT-UK Colloquim Videos Aavilable Online * FUNcube Certificate of Achievement and QSL Card * Upcoming ARISS Contact Schedule SB SAT @ AMSAT $ANS-214.01 ANS-214 AMSAT News Service Weekly Bulletins AMSAT News Service Bulletin 214.01 From AMSAT HQ Kensington, MD. August 2, 2015 To All RADIO AMATEURS BID: $ANS-214.01 Fox-1A Mated to the Centaur for Launch AMSAT-NA's Fox-1A satellite which will launch on a NASA ELaNa flight from Vandenburg AFB has been mated to the Centaur upper stage which will carry it to orbit. A photo of the NPSCuL mated to the Centaur with the P-POD containing Fox-1A, BisonSat, ARC1 and 7 other P-PODs can be seen on the AMSAT website. http://www.amsat.org/?cat=21 [ANS thanks Jerry, N0JY, for the above information] --------------------------------------------------------------------- AMSAT 2015 Symposium Papers The 2015 AMSAT-NA Annual Meeting and Space Symposium to be held on the weekend of October 16-18, 2015. Proposals for papers, symposium presentations and poster presentations are invited on any topic of interest to the amateur satellite community. We request a tentative title of your presentation as soon as possible. The final copy must be submitted by September 15 for inclusion in the printed proceedings. Abstracts and papers should be sent to Dan Schultz at n8fgv at amsat.org The 2015 AMSAT Space Symposium and Annual Meeting will be held October 16, 17, 18, 2015 at the Crowne Plaza Hotel, 33 East 5th Street, in Downtown, Dayton, Ohio. [ANS thanks the 2015 Symposium Committee for the above information] --------------------------------------------------------------------- PCSAT Default Beacon Transmissions on 144.390 MHz An FM APRS signal has been received in England causing interference to the MGM frequency and weak-signal Meteor Scatter (MS) operation which is just below 144.390 MHz. A MS DXpedition was disrupted by such activity earlier in the month and interference has been occurring at various times since. Bob Bruninga, WB4APR, explains that the beacon was planned over 15 years ago for operation only when PCSAT is over North America based on published band plans at that time. Now, after 14 years on orbit, the ability to turn that backup beacon off has been lost. PCSAT (now 14 years old) had a backup fail-safe beacon on 144.39 that would activate after any unknown spacecraft reset to give a backup comm link in case the primary 145.825 channel died. Being on the North American APRS frequency with hundreds of IGates there would always be at least one that would hear this "emergency call home" from PCSAT even though the channel is generally saturated. It worked. The problem is, that now PCSAT resets on every orbit due to negative power budget and so, on every orbit that beacon comes back on. Even if we did get a command up to reset it, that setting would last only 15 minutes to the next eclipse. We learned our lesson! That was our FIRST amateur satellite and we sure learned NOT to use a "connected-packet-command link" that needs ACKS and Retries and logon passwords just to LOGON before you can even send a SHUTUP command. All our satellites since, operate without the multiple Send, connect, ACK, retry, ACK, command, ACK overhead.... just to get one command understood. Now, only the receiver on the spacecraft has to be functional to command it to silence in a single packet. But too late for PCSAT. We are sorry that we have no good answers. But we hope we can mitigate this instance of "friendly fire" collateral damage so that we don't cause an overall black-eye to amateur radio overall friendly operations? What you may hear will be 2 one-second packets per minute, one at 1200 baud and one at 9600 baud, trying to "call home". [ANS thanks Bob, WB4APR, for the above information] --------------------------------------------------------------------- 2015 AMSAT-UK Colloquim Videos Aavilable Online Thanks to the cooperation between the BATC and AMSAT-UK, this years colloquium footage is becoming available online already. The BATC and AMSAT-UK teams are working to upload all video material on to the AMSAT-UK YouTube account.

CW heard
by Richard Lawn 01 Aug '15

In FN21, the northern Pocono area of PA near Scranton, I copied "MOVE1" every 60" around 145.975 +- Doppler. The time was 14:25 UTC give or take. Anyone know what I heard? At it's peak the signal was 59 here while I was waiting for one of our ham sats around that same freq. Rick, W2JAZ

Decoding UO-11 (UOSAT-2)
by Bob KD7YZ 01 Aug '15

01 Aug '15

Once I got the correct Mode-Setting for UO-11, I had no trouble getting what I think are good decode sets. Others here had said UO-11 gives garbage decodes. The last couple days I have gotten true garbage, a snippet here: -------------------------------------------------------- 0pA}4VRX 4CKIp(zhp#W13 z R<#`{M|4C 2Gr%xa5,RtCX`Xa\:#X{ <("!"i(TpB?B$B7(4="BzF<("ai)5H)0L$0\C/~HPT, $"b}EE=0"lw` L`V A-.7Pq\E54,xX|/ab(+F! ^88 (a`h"i!B @, #%\95!!_C$[P`dD &4 XhQHV3& )FPj( rPA4-`}BH!}0PF!/B-.H9)GP0jSDd rI"-<er HbP 9fQyMb3\@`1_`TEBfS(!YhyC&a@9Dt%|&8N5U0A.N7TX"@k82!|`FF@PtT!ed@dLtr12^I $#xP"VvIBJ$ -------------------------------------------------------------- So this morning I started fiddling around with the Mode-Settings Charset as-well-as Invert. I walked thru the available Charsets in UISS. Then I toggled Invert for each. Finally when I got back to Ascii-7 and inverted, it all worked/decoded. ------------------------------------------------------------------------------- 000000010001020002030003040004050005060006070007080008090009 100001110000120003130002140005150004160007170006180009190008 20000221000322000023000124000625000726000427000528000A29000B 30000331000232000133000034000735000636000537000438000B39000A 40000441000542000643000744000045000146000247000348000C49000D 50000551000452000753000654000155000056000357000258000D59000C 60800E615FC1620105633341644402651E0C66200267000168000E69000F UOSAT-2 1408060015554 000000010001020002030003040004050005060006070007080008090009 100001110000120003130002140005150004160007170006180009190008 20000221000322000023000124000625000726000427000528000A29000B 30000331000232000133000034000735000636000537000438000B39000A 40000441000542000643000744000045000146000247000348000C49000D 50000551000452000753000654000155000056000357000258000D59000C 60800E615FC1620105633341644402651E0C66200267000168000E69000F UOSAT-2 1408060015559 -------------------------------------------------------------------------------- I am certain the Mode-Settings were the same from begin with garbage decodes to end when I returned them to original settings. go figure. 73, -- Bob KD7YZ http://www.qrz.com/db/kd7yz AMSAT LM#901

LVB Tracker Question
by Greg 31 Jul '15

31 Jul '15

Hi all, Been about 4 weeks since I went and turned my sat radio on and rotor. The rotor is a G5500 with and LVB Tracker. I noticed that the azimuth reading on the LVD Tracker display is not stable and jumps around to 350-370 degree’s when the antenna is parked at 360 degrees. Playing with the voltage quickly in the back can change the Tracker display from 350-800 degree’s. Not sure if this is a wiring issue to the rotor as I had some landscape done and we had heavy rains this summer. The rotor turns on command when using Nova or PCsat and if I follow a satellite the needle on the Yaesu box is close to indicated satellite azimuth on the program. Howver, the Tracker will still jump around 10 degrees from that needle heading. Ideas welcomed? Greg N3MVF
