Has the ability to use the FR24 box as a NTP Stratum-1 time server been implemented? If so how do we access it? and if not are there any plans to enable this feature? as it would make a nice additional feature seeing as it has a precision GPS time source.

NTP time server possible?

Although it sounds easy, it requires some resources available in the hardware (in this case, the FR receiver):
a) We need a dedicated port to output the data frames containing the time stamps (typically a NMEA 0183 in a serial port)
b) A PPS (pulse per second) output, this signal enable the attached device to "know" when is "starting" the actual UTC second. (Only if you want to have your networked PC's linked to a "stratum 1" server
c) And of course, available memory & processing capacity.
For those interested in having their own "atomic clock" running under their home desktops, I would recommend this options:

http://ntpi.openchaos.org/pps_pi/
Unless you are running time critical processes in your LAN, (for example, a networked Lightning radar device as I run ) I would recommend using a NTP client, there is a lot of packages for doing that in Windoze boxes, and the NTP client comes by default in most linux distros.

Originally posted by F-EGLF1 View PostThe radarcape board used in the FR24 box was designed with NTP capability, it should just be a matter of writing the firmware to enable it on a known port over ethernet, this has been done with the Blitzortung lightning detector hardware with a firmware upgrade a few weeks ago, it should be possible to do the same on the FR24 boxes as they have sufficient processing power and speed.

Is it possible or be a way to add a NTP server address to the FR24 box like the DNS settings? I operate a Statrum 1 NTP server via GPS on my network.F-KPNS2
