Default Re: Off Air Frequency Standards....

Coming to this thread late. I use a Trimble Thunderbolt GPS unit. That has outputs at 10MHz and 1pps. The 10MHz is the external standard for my HP 5328A counter.

It is fed from a Trimble bullet antenna on a pole on the end of the house with a good view of the sky.

The Trimble has an RS232 output, which is fed via an RS232-USB convertor from Maplin.
