Dear Patrick,

<div class="">I build a stratum-1 NTP server with a rubidium reference. You can get used one in the market for some few hundred EUR.</div>
<div class="">As spare documentation about my project you can find at my blog <a href="http://blog.mayer.tv/2017/06/11/stratum-0-server.html" class="">http://blog.mayer.tv/2017/06/11/stratum-0-server.html</a></div>

Has anyone tried to create a low-cost stratum 1?<br class="">
Is the minimum cost a chip-scale atomic clock?<br class="">
<br class="">
<br class="">
Thanks!<br class="">
Patrick<br class="">
