  • v1.79 Reboots

    Yep, definitely a bug. v1.80 will go out in a couple of hours, or you can get it now by restarting the server.

    Sorry about that. Getting more difficult to keep this thing afloat. I appreciate everyone's assistance.

  • Worried about time?

    Sure, but be careful. For some people this is a slippery slope into full-blown "time nuttery", e.g. Time-Nuts, LeapSecond.com. Believe me, I know. It starts with PPS-producing GPS modules. But then quickly escalates into buying a GPSDO and/or surplus rubidium OCXODO from that Ebay guy in China. All of a sudden you're building your own GPSDO. Then acquiring an old hp 5370A/B TI counter, or two, or three or ten. Perhaps even adding my CPU upgrade. Then you score your first cesium standard off Ebay. You might even get one with a semi-working beam tube. Pretty soon the Allen deviation/variation plots are flowing and three-corner hat comparisons being made. This list is maybe 2% of what's likely to happen.

    Now things really fall apart. You decide you need a hydrogen maser. So the sports car and/or summer home get sold to raise the cash required..

    Absolutely no cure, except to get distracted by something equally interesting/addictive.

  • KiwiSDR Clock Lags?

    jksjks
    One thing I could do I suppose is have the Kiwi server occasionally check for NTPd running and restart it if necessary.

    Something like that always sounds simple. But when it comes to implementation there are always funny edge cases to consider and the possibility I'll release a version that bricks everyone's Kiwi. I've been lucky about that so far..

  • Using BB Black wireless or BB Green wireless board

    Yes, a WiFi dongle on the end of a USB cable with some type 77 and/or 43 toroid cores as a common mode choke is a great idea. Be sure to use a 5V power supply of at least 2A. The Beagle manual warns about the increased current requirements when using WiFi dongles.

    A long Ethernet cable shouldn't be a problem (the spec is 100m max). Just use toroids as above at the Beagle end. Because Ethernet uses differential signaling it isn't much of a problem except for the EMI from elsewhere that rides down the cable common mode. Be sure not to use shielded Ethernet cable as this may cause a big ground loop depending on your equipment grounding.
