[time-nuts] NTP REFCLOCK for a Jackson Fury??

[Frank Hughes]

Hi,

What NTP REFCLOCK can be used for a Jackson Fury?

I know that the Jackson Fury docs suggest using:
http://www.realhamradio.com/gpscon-info.htm

But that means I would have to put up a windows server
to replace the FreeBSD ntpd server I built for use w/ the Trimble TB.

Looking for open source options, if possible.

Thanks,
Frank
