[time-nuts] Shielding a DAC line

[Bob Stewart]

I made some minor hardware changes to my GPSDO today and I see that it's locked to a new DAC voltage about 21mV higher.  So, I was wondering about shielding the short run to the OCXO.  I have immediately available RG-174 and I'm putting that in.  But, should this be some sort of steel shelled semi-rigid coax?  Maybe it's a dumb question, but I thought I'd ask.
