First field tests of two SPEC boards running a White Rabbit timing link between them have been made in Siberia. These tests are made by DESY to verify the usability of the board at the Gamma-Ray and Cosmic-Ray experiment HiSCORE-EA at the Tunka site. Full results of the tests will be made available soon. Two kilometres of fibre where outside, while the SPEC boards were nicely warm inside the counting room.
