Subject: Spectracom IRIG-B card installed on fb1 

[EDIT: corrected name of installed card]

We just installed a Spectracom TSyc-PCIe timing card on fb1.  The hope is that this will help with the GPS timeing syncronization issues we've been seeing in the new daqd on fb1, hopefully elliminating some of the potential failure channels.

The driver, called "symmetricom" in the advLigoRTS source (name of product from competing vendor), was built/installed (from DCC T1500227):
