On the EEVBLOG  (http://www.eevblog.com/forum/index.php)

They mention that the "2014-11-06"version GPSDO that was “most extensively tested, so far (by ke5x and others).

(Has a) known bug, outputfrequency is not exactly 10mhz (9,999,999.999,800 Hz). This translates to ~2hzerror at 100ghz.”

A question is if this bug isjust for this particular model or all other versions suspect?

I realize that in and of itsself it is very small error, but errors tend to multiply or cause incorrectconclusions to testing.

Another question is will the LHdisplay unit they offer work with other Trimble units such as are offered byRDR?

That said, these models seem tobe a very nice turn-key systems.
