[time-nuts] Jupiter T question

[Richard and Marcia Putz]

Hi All, 
The otherday I asked about the Jupoiter T receivers and Brooke mentioned the results of his experience with it, I was curious what he meant when he spoke of the "clock zero-beat times (TvB calls them "hanging bridges")" .Brooke, can you or Tom direct me to somewhere where I might get a better understanding of this?
Thanks; Rich
