        Hi, Dave, Great video!
        How is the other from cell tower rubidium oscillator from eBay doing? – the one you did a teardown with before. Could you do a short follow up video to compare its frequency against these two? I’m asking because I thought about buying it and then using as a standard to calibrate other stuff.

          I have one of those too (FE-5680A).
          It would indeed be interesting to see how they compare to Dave’s SRS, FE unit if it works, GPS timming and oven stabilized xtals….
