[time-nuts] TS2100: Upgrading oscillator?

Check out the archives around 3/2011 and 6/2015 for some discussions 
about upgrading the TS2100 to an OCXO.  Gerhard Wittreich's post on 
6/6/2015 describes the process.  Greg Dowd from Symmetricom added quite 
a good bit of info to the discussion in 2011 so be sure to check out 
those messages too.  The intended OCXO is an MTI 240-0530-D (see 
attached pic) but is a custom part.  It was not available when I 
upgraded my unit so I used a different OCXO that I put on a small 
perfboard and wired in. There were some available on eBay last year but 
now they're gone. The EFC range is 0-6V but I believe the onboard DAC 
only drives it from 0.5 to 4.5V.  The OCXO datasheet is available on 
Manuals section of the KO4BB site.
