[time-nuts] Trimble Mini-T GPSDO

Hi Nigel,
from what I heard from our customers (I have not had a unit to test myself, 
 and do not have any comparative data), many if not most of these units 
have  frequency jumps, and are not nearly as good as the Thunderbolt (which is 
quite  good, and very well documented in the Time Nuts Archives).
If you plan to buy these new, there is apparently also an issue with  
meeting delivery schedules, and having (hand-selected) sample/evaluation units  
perform much better than actual mass-production units. One reason why several 
of  our customers abandoned the Mini-T for our FireFly GPSDO's. Again this 
is  second-hand information though.
Lastly, these unit's are all built using RoHs lead-free solder without the  
option to use the Telecom exemption for leaded solder, so in my  opinion 
reliability is at best reduced compared to Telecom  products still using 
leaded solder due to the nasty tin-whiskering problem with  RoHs solder.
The above opinions are mine and not necessarily those of my employer  :)

Hi  All

I've been looking through the list archives for anything on  the  Trimble 
Mini-T but have found very little, and what little I  have found  didn't 
across as particularly encouraging.

Is  anyone currently using these, or has run tests on them, and able to   
offer any comments on performance and how they might compare, for  example, 
the  Thunderbolt?
