The TLEs have \nbeen updated on the Cubesat website, www.cubesat.org. There will also be \nupdates from Kosmotras regarding the status of the launch as soon as possible \non the website and the discussion boards. The discussion board at \nhttp://polysat.calpoly.edu/irc/ will be available to allow satellite trackers \nto discuss what's been found.\n\nFour-of-seven CubeSats will be using Amateur Radio frequencies and modes as \nfollows:\n\nCalPoly PolySat CP3\n436.845MHz (1W) 1200bps FM AFSK AX.25 (Part-5 experimental license)\nhttp://polysat.calpoly.edu/\n\nCalPoly PolySat CP4\n437.325MHz (1W) 1200bps FM AFSK AX.25\nhttp://polysat.calpoly.edu/\n\nCP4 will autonomously transmit a sensor snapshot once every two minutes while \nin orbit. This transmission will be on 437.325 MHz, at 1200bps FSK, using \nAX.25 packetized digital data. Please note that it is FSK, not AFSK, which \nwill require you to set your radios to \"single side band\" (SSB) instead \nof \"FM mode\". This sensor snapshot is preceded by a six second CW preamble \nthat can be decoded as the satellite's call sign. CP4's autonomous beacon \ncontains sensor data that can be used to determine satellite's health status. \nA program that can make sense of the binary data encoded in the AX.25 packets \nwill be made available to community soon (probably through the PolySat \nwebsite). The information in this beacon would be useful along with the \nrecorded receive signal strength, should any anomalies occur early in our \nmission.

This problem \nhad gone unsolved since launch until the relationship to the receiver was \nfound. The good news is the problem goes away when that receiver is shut off. \nThe bad news is that particular receiver is the only user receiver the \noperating system allows to access the BBS. A rewrite of the core operating \nsoftware is required to work around this issue, and there is exactly one \nperson who can do this. For the mean time AO-51 will primarily be an analog \nmode satellite, until the fix is coded and tested thoroughly on the ground.\n\nSometime soon there will be a test of the new automatic scheduling software. \nThe command stations will set up a series of about 10 mode changes over a few \nweeks, with the schedule announced in advance. When this happens we'll \nappreciate reports via the amsat-bb and ao51-modes lists. We may also run \nsome power output tests, setting the downlink transmitters to different \nlevels and asking for quantitative reception reports including a detailed \ndescription of the receiving station.\n\nI would like to mention my support and appreciation for the \nhttp://oscar.dcarr.org/ website. It is near real time information, and \nupdates whenever a new report is added. I absolutely LOVE this tool, and \nwould like to thank the creator, and encourage it's continued use. If you \nnoticed last week there were a few reports of AO-51 \"not heard\". In fact the \nsatellite was transmitting, but the auto battery protection had tripped, \nreducing the downlink to 100 mw that morning in lieu of the normal ~500 mw. \nLater that day the auto protection tripped again, shutting TXb off. I noticed \nthe reports and immediately called one of the command stations, who was \nalready aware of the problem. I bring this up because it is a great tool for \nusers that we in Operations also use, and it seems to have several regular \ninternational contributors.\n\n[ANS thanks Drew, KO4MA, for the above information]\n\n/EX\n\nSB SAT @ AMSAT $ANS-105.04\nRAFT and ANDE Update\n\nAMSAT News Service Bulletin 105.04\n From AMSAT HQ SILVER SPRING, MD.\nApril 15, 2007\nTo All RADIO AMATEURS\nBID: $ANS-105.04\n\nRAFT and ANDE are now coming over in the prime eveining hours. \n\nIn fact, if you look at RAFT you will see it is nearly sun synchronous, in \nthat it is coming over nearly the same time every evening. That is about \n7:45, 9:15 and 10:45 PM local sun daylight time at mid (40 deg) N latitudes.\n\nPA3GUO reloaded RAFT settings and the packet-to-voice synthesizer is \nenabled.

Also, RAFT is \nonly useable in the dark, so we don't have many more operating periods to \noperate this unique transponder.\n\nAlso, if anyone has lots of power on 10 meters and will use it to TX CW, we \nwould like to activate the PSK-31 transponder and try again at hearing some \nsignals.\n\n[ANS thanks Bob, WB4APR, for the above information]\n\n/EX\n\n\nSB SAT @ AMSAT $ANS-105.05\nCall for Papers--2007 ARRL/TAPR Digital Communications Conference\n\nAMSAT News Service Bulletin 105.05\n From AMSAT HQ SILVER SPRING, MD.\nApril 15, 2007\nTo All RADIO AMATEURS\nBID: $ANS-105.05\n\nTechnical papers are solicited for presentation at the 26th Annual ARRL and \nTAPR Digital Communications Conference to be held September 28-30, 2007 in \nHartford, Connecticut.

St. Michael’s Primary School Contact Successful\n\nOn Monday, April 2, students from St. Michaels Primary School in Daceyville, \nNew South Wales, Australia participated in an Amateur Radio on the \nInternational Space Station (ARISS) contact. Sixteen students asked Michael \nLopez-Alegria, KE5GTK, one question each as approximately 180 children in \ngrades K-6 looked on. National television and newspapers covered the event.\n\n\n2. Successful Contact with Glenden State School\n\nGlenden State School in Queensland, Australia experienced a successful Amateur \nRadio on the International Space Station (ARISS) contact on Wednesday, April \n4, 2007. Astronaut Sunita Williams, KD5PLB, answered questions from sixteen \nstudents and was answering the seventeenth question as the ISS went over the \nhorizon. Approximately 400 teachers, students and others attended the event. \nA local news crew was there to film the event, and two radio interviews were \nheld, one before the contact and one immediately after. Another local radio \nstation publicized the event during the week prior to the contact. The audio \nfrom this contact was fed into the EchoLink AMSAT (101 377) and JK1ZRW (277 \n208) servers. Among the eight countries that connected (a total of fifteen \nwere made) were Macedonia, India and Ireland. \n\n\n3.
