[time-nuts] Thunderbolt serial port problem UPDATE

[David Bobbett]

Further to this discussion, my fluke.l monitor has never decoded the 
Tbolt oscillator voltage, although all other data is displayed 
successfully.  I contacted fluke.l regarding the problem and he promised 
to look into it - that was over a year ago and I have heard nothing 
since. As a precaution I have retro-fitted the missing components, a la 
Didier, it doesn't address the data display problem of course, but 
otherwise the monitor works OK. Just don't think you'll get any 
after-sales support!
