I have received, at work, 12 Spectrcom TPRO-PCI cards. These are the evolutionary successors to the KSI/Odetics TPRO card. I also have the Linux driver for the 2.6 kernel for these cards. Has anyone had any experience using this card as a reference clock? If not, I will attempt to modify refclock_tpro to use this card and driver. Tim Keck
