Having just considered the different options, for pretty much the same reasons, I ended up with plans for Garmin's GPS15L, an external antenna, and making a short cable to the main board of the server that is supposed to run the sync service. Although it doesn't (as such) has pps, but given that my OEM mainboard (AsRock) has a connector for "IR Header", I can create a connector that powers the chip from the mainboard, and connects the TX/RX wires there. Using standard NMEA protocol, and knowing the latency of the port itself, it can give me a fairly good, and simple to maintain, clock. It won't be perfect, but it won't perfectly break my bank account eighter. //Svein -- Svein Skogen | [EMAIL PROTECTED] Solberg Østli 9 | PGP Key: 0xE5E76831 2020 Skedsmokorset | [EMAIL PROTECTED] Norway | PGP Key: 0xCE96CE13 ------------------------+----------------------------- msn messenger: | Mobile Phone: +47 907 03 575 [EMAIL PROTECTED] | RIPE handle: SS16503-RIPE
