[time-nuts] DIY FE-5680A lobotomy (disable temp compensation)

[EWKehren at aol.com]

Will someone beside us use heat pipe. Would love to have an impendent  
input. What does it take to get a test going. Scott has done a lot of work, how  
about some one else step up to the plate. There are a lot of time nuts out 
there  with the 5680A,many for the first time will have a very good 
reference and some  of our experts with proper equipment can make a big difference.

No. I've only traced back from  the ADC input to the voltage divider.

I have not.

It does sound messy. I don't think I'm willing to dunk one of  my units.
