[time-nuts] Tbolt altitude error

No,
 
one is reporting in MSL, the other in GPS height.

There is about a 30m difference between the two here in Santa Clara  
county, CA, similar to what you are seeing.

I had a Tbolt and a Z3801 both fed from the same  antenna and they indicated
26 meters differenence in altitude. The 3801  seemed closer to right. If
geoid error were the cause, it seems that both  would indicate about the
same.
