Signals have been received from the three CubeSats launched April 25 on Soyuz flight VS14 from the Kourou spaceport in South America.
The three CubeSats were developed by student teams under the European Space Agency (ESA) Education Office “Fly Your Satellite!” program, which is aimed at training the next generation of aerospace professionals. The satellites are OUFTI-1, Université of Liège, Belgium; e-st@r-II, Polytechnic of Turin, Italy; AAUSAT-4, University of Aalborg, Denmark.
The signal from the e-st@r satellite 1200 bps beacon is very weak which may indicate an antenna deployment issue or unexpectedly low transmit power. ESA report the e-st@r team is working to consolidate the radio communication link with their satellite.
OUFTI-1 carries the first dedicated amateur D-Star satellite transponder, further information and frequencies of all three CubeSats are at
Daniel Estévez EA4GPZ used a FUNcube Dongle Pro+ and a handheld Arrow Satellite antenna to receive a signal from AAUSAT-4, call sign OZ4CUB.

ESA Fly Your satellite! CubeSats phoned home
The European Space Agency (ESA) Education Office will give a prize to the first three radio amateurs to send a recorded signal from either the AAUSAT4, E-st@r-II or OUFTI-1 CubeSats which are expected to launch Monday, April 25 at 2102 UT.
The launch of the three CubeSats on a Russian Soyuz-STA Fregat-M rocket from Kourou in South America had been planned for Friday but suffered a series of postponements due to bad weather.

Soon after being deployed into their final orbit, the CubeSats will begin transmitting signals to Earth that can be picked up by anyone with common amateur radio equipment. ESA challenges anyone to record the signal and send it to firstname.lastname@example.org, and to the CubeSat team.
For each CubeSat, the first email received for which the signal is confirmed to belong to the CubeSat will be awarded with the following prizes:
• ESA Fly Your Satellite! poster
• ESA Education goodie bag
• Scale 1:1 3D printed model of a CubeSat

The OUFTI-1 D-STAR CubeSat team have released the format of the CW telemetry beacon and a Decoder App. The launch, on a Russian Soyuz-STA Fregat-M from Kourou in South America, is expected to take place at 21:02:13 UT on Saturday, April 23, 2016.
OUFTI-1 is a nano-satellite entirely developed by the students of the University of Liege (ULg), Belgium, along with two other engineering schools. It is the first satellite to carry a dedicated amateur radio D-STAR transponder.
