Hello Joe, thanks for the feedback and questions! Some other members asked for more details, I will send out more technical details in the next day or two. You can make an SNTP time server with the FireFly or Fury GPSDO in two ways: 1) The simple way of doing it: Connect a PC running GPSCon to either one of the two units via the serial port. GPSCon is quite inexpensive and works pretty well. It has a built-in SNTP server function among other features. I believe you can get it for less than $50 at realhamradio dot com. All you need is a Null Modem Cable, and PC with the software installed. 2) This way provides tighter timing accuracy, but requires soldering a single wire: For better accuracy, you can run SNTP or NTP server software on a Linux PC, and connect a 1PPS RS-232 level compatible signal to pin 4 of the Fury or FireFly DB-9 connector. The PC will trigger on this signal (usually connected to DCD on the PC side) and provide a high accuracy time server. You can search the Time Nuts archives on how to set up Linux to do this. The Fury and FireFly both support this 1PPS RS-232 level signal on the PCB, but it's not connected to the RS-232 connector by default. The user has to wire it up to the DB-9 connector. Let me know if anyone wants details on how to wire up their RS-232 connector for this. Hope that helps, bye, Said In a message dated 3/25/2008 14:53:28 Pacific Daylight Time, [EMAIL PROTECTED] writes:
Looks very cool! So how do I make, or have my Network Administrator make, a NTP time server from one of these or one of your other products? I am technically inept and am in the market for a time server, Meinberg's are nice but out of my budget. Any help is appreciated.

Wanted to share with you that we have shrunk our Fury GPSDO into a 1 inch x 2.5 inch x 0.5 inch tiny little package, called the FireFly. It's the most inexpensive new GPSDO that we know of at this time. It's less than 1/2 the size of a credit card. The unit has a subset of the Fury SCPI commands, generally it has the same features as the Fury. The performance is pretty good too, and power consumption was reduced to < 1.4W at 12V using a high-stability small OCXO. We are using a highly sensitive mobile GPS receiver now, so it can be used in a moving car etc. The GPS receiver is sensitive down to -151dBm tracking. Some preliminary specs are available at _www.jackson-labs.com_ (http://www.jackson-labs.com) We are sampling the units now. Let me know if anyone is interested in more details, we are presently fully qualifying the unit. Bye, Said **************Create a Home Theater Like the Pros. Watch the video on AOL Home.
