[time-nuts] Red Box T'bolt (was: Trimble T'Bolt)

Thanks Ian
 
Sounds like my original comments were somewhat over pessimistic  then!
 
I was under the impression that the crossover between oscillators was  
around 2002 but obviously it must have been quite a bit earlier.

Hi  Ian

That sounds encouraging, what's the date code on yours?

I  seem to recall previous discussions here regarding the possibility of   
firmware upgrades and am pretty sure the answer was "No".

My  current Tbolts have firmware 3.xx but I have had some in the past with  
 
version 2.xx and don't recall any obvious  differences.

Hi  All,
I purchased one of these "red box"  t'bolt from this Israeli seller and  it 
arrived a couple of days  ago.
I can confirm it has the Trimble labeled  OXCO and firmware  FW2.12.
Also interesting is that it seems to run happily  with the  supply backed 
off to 17V.

I've taken some pics with the  boards  spread out and uploaded them to 
Didiers site.
The file is  called  RedBoxThunderbolt.pdf and should be available shortly.

As  with many  things found on fleabay, a gamble is involved. In this case  
it seems to have  paid off.

Is it possible (and is there any  benefit) in updating the  firmware?

cheers,
ian
