Happy Birthday FUNcube-1 (AO73) Thursday, November 21, 2019, saw the sixth birthday of the launch of the amateur radio CubeSat, FUNcube-1 (AO73) A very short time after the launch from Yasny in Russia and within a few minutes from deployment, the very first frame of data from the low power transmitter on board, was detected and decoded by ZS1LS in South Africa. He was able to relay the data over the internet from his Dashboard to the Data Warehouse and the numbers, appeared, as if by magic, at the launch party being held at the RSGB National Radio Centre at Bletchley Park. After a very brief check out, the FUNcube team were able to switch the transmitter to full power, again at the very first attempt, and were quite amazed at the strength of the signal from the 300mW transmitter on 145.935 MHz. The transponder was then switched on and successfully tested. The team finished the day with a request to AMSAT-NA for an Oscar number and were delighted to receive the AO73 Oscar 73 designation!

In excess of 32000 orbits, 750 million miles travelled, and with more than 7 million data packets downloaded and stored in the Data Warehouse. The spacecraft is presently in continuous sunlight and to convert as much of the sun’s thermal energy into RF (to help keep it cool), it remains in continuous high power telemetry mode. We anticipate this situation will continue until early May next after which we expect to have 3 months with some eclipse periods. Of course, EO88 – Nayif 1 continues to operate autonomously with the transponder active when in eclipse and JO99 – JY1Sat, which includes image downloads, and which was launched just under a year ago, also remain active on a 24/7 basis. The FUNcube team still receive many requests for Fitter message uploads for school events…please contact them by email to operations@funcube.org.uk giving at least two weeks notice. The FUNcube team continue to be very grateful to all the many stations around the world that continue to upload the telemetry that they receive to our Data Warehouse. We really need this data to provide a continuous resource for educational outreach. With that in mind, here is a link to a previous update which shows the correct current Data Warehouse address and the Dashboard software that can be used for each spacecraft https://funcube.org.uk/2019/01/21/funcube-dashboard-summary-update/ FUNcube email group https://groups.io/g/FUNcube FUNcube Forum http://forum.funcube.org.uk/ FUNcube Website http://www.funcube.org.uk/ http://www.southgatearc.org/news/2019/november/happy-birthday-funcube-1.htm
