MHz signal that excites the CBT, as explained in my FCS paper in the early 90's. I don't understand how you got worse phase noise with a DRO than a VCO, unless you used a narrow loop bandwidth for the DRO and a wide loop bandwidth for the VCO. We try to get the loop bandwidth up around 1 MHz for DRO's.

They did a paper at FCS(?) on the results. Back then being able to actually get very accurate phase data over a 100’s of mile range was a pretty novel thing. Using GPS timing for this actually pre-dates the whole CDMA / GPSDO thing.

I have a set of 10 cables bought off the *bay with such connectors. These cables are 75 ohm, so there will be a mismatch in a 50 ohm system no matter what the connector is. I am not sure what would make those less *true* that anything else.

I was at an IEEE conference a few years ago on high speed interconnects (10 Gbps is slow for those guys), and a bunch of the folks were talking about how too much time is being spent on trying to get impedance controlled connectors, instead of reliable connectors.
