Hi all,
I'm thinking about building a GPS-disciplined 10 MHz reference oscillator. Of course, I'd like to add some networking features to it :-)
NTP server is the most obvious, and is well documented.
But I'd like to be able to carry 10 MHz reference signal to various locations in the shack over network cabling. My first idea is about using existing converters for TV/SAT : - RF to Ethernet passive couplers (a F connector tied to pins 1-2 of a RJ45 connector, $1 on Chinese warehouses). Will it work at 10 MHz ?
Anyway, I do not have any idea about whether it will work or not while maintaining the reference/stability purpose of the 10 MHz signal.
You need to be lookng at PTP if you're using a high stability clock and distributing it to PTP consumers:

PTP daemons tend to support NTP as a fall-back protocol.
