Dr Chris Bridges M6OBC from the Surrey Space Centre has advised that the amateur radio beacon on their STRaND-1 CubeSat became intermittent over the Easter weekend.
Radio amateurs, especially those outside Europe, are asked to listen for STRaND-1 over the next few days and report any positive results to C.P.Bridges at surrey.ac.uk . Listen for a 9k6 signal around 437.568 MHz (+/- Doppler).
