I’m asking mainly because a *lot* of this is a “make one thing worse to make another thing better” kind of process. Very accurate time ( = very close to the GNSS timestamp) is directly opposed to clean frequency. A box that is “better” for time likely is “worse” for frequency. ( yes, some are pretty bad at both …). A SRS 740 with the Rb option is one of the alternatives….. Pricing for all the options is on their web site.
