That's a Garming GPS-18 PC, the version that gets power from a cigarette lighter.

What do you mean by "stratum 0"? I'm assuming you mean for use with ntpd. The telephone industry has a different meaning. There are two quirks in this area. One is that the GPS-18 has been updated to the GPS-18x. It's much more sensitive. The other is to be sure to get a version with a PPS. In particular, the USB version doesn't have it. Lots of people use the GPS-18-LVC with ntpd. Info here: http://support.ntp.org/bin/view/Support/ConfiguringGarminRefclocks You have to provide power. "Some assembly required.", but it's not a big deal if you know how to drive a soldering iron. There are a couple of good links at the bottom of that URL above. > Make a linux box into a master time source...

Lots of people use the GPS-18-LVC without windows. > EBU Timecode in LTC format (audio timecode) The NTP source code package includes a utility to make audio time codes. Look for tg2.c. I don't know what EBU is, but that code might be a good place to start. -- These are my opinions, not necessarily my employer's.
