That is the info I was looking for. My T-bolt works very well but all three supplies are regulated. So I have to come up with regulated +12V and -12V.

All three seem to be quite consistent. 10MHz from the NTP server is not as stable as the other 3. The 1pps from the NTP server wanders +/- 50ns from the 1pps from the T-bolt. All are running from the same GPS antenna outdoors with a pretty much unobstructed view of the sky. (I have some trees and the peak of my roof up to about 20 degrees above the horizon to the S.)
