Build a 10MHz Rubidium Frequency Standard and Signal ...

Aug 07, 2013· Gerry, thanks for the You Tube videos on the Rubidium 10 MHz frequency standard and Video Distribution case. I used your videos to house my FE5860A and everything worked out nicely. I did move one of the 10 MHz outputs to the front panel. Now I need to make a housing for my Thunderbolt GPSDO so that I can compare the two frequencies.
