I did not post-process anything from the XH
Check your datum. This is likely a GRS80/WGS84 translation issue.
I'm assuming you're running TerraSync? Are you running a real-time correction by chance?

I am saving this quote!
Shift from US Survey Feet to International Feet is small in NJ because the coordinates at the zone origin are small (N=0m and E=150,000m). For contrast, see origin values for Virginia, Utah, Texas, Michigan, Nevada, and Colorado on page 64 of NOAA Manual NOS NGS 5.
For example, see point KV6027 in Trenton, NJ.

(12 inches/foot) / (39.37 inches/meter) = legal definition of US Survey Foot per NGS
0.3048 meter/foot = legal definition of International Foot
501,448.64*(12/39.37-0.3048)=0.31 m

Isn't this because NJ has 1 zone? I had always heard real time anything in Nj was bad because of this.
I think the number of zones is nearly irrelevant.
The difference in coordinates of the two definitions of a foot depends on the distance from your location to the defined 0,0 point, which depends a lot on what they defined for the false northing and easting.
For most states the false northing and easting makes the 0,0 fall a state or two away from the actual zone, so multiplying that by the difference between foot diefinitions is large enough to be obvious in the coordinates.
