The ADEV of this cheap VC-TCXO with Vtune at 1/2 Vcc is not bad: 0.1 s | 2e-10 1 s | 1.5e-10 10 s | 0.9e-10 100 s | 2e-10 With the Vtune at GND the ADEV is even much better so there is still some more investigating to do.

Nevertheless, for a single bench setup like mine, the distribution amplifier will probably serve adequately well to distribute 10 MHz from a T-bolt to the counters, divider board, and a signal generator -- all on the same bench. As the R, G, & B DA inputs can be looped, the ADA3 80 can provide up to nine 10 MHz outputs via BNC connectors.

Hi Everyone, I just finished my report from the BBC Pelagic trip out of Hyannis, Mass on November 10. The trip started in Hyannis and went to Monomoy Shoals to just north of Nantucket Shoals from 7:00 am to 3:00 pm. Ckick here: http://coastalbirds2.blogspot.com/ The report with many images is three pages on my blog.
