Hi Joe, VLF,
Same problem at RC4HAA. They put their grabber online at
http://136.su/grabber/ and granted remote acces to their PC. The PPS
looks like in the attachment. Looks like a C is shorting the pulse.
However there should be no C in the circuit.
Has someone an idea? Does it happen on some soundcard types? Maybe a
large C like 1000uF would help?

Yes, pps and NMEA to SpecLab but evidently no discipline yet. The pps
pulse looks strange on the SL scope and there are 'PPS zero-crossing
too flat' debug errors on SL SR correction. This is all the NEO7M
seems willing to provide at the moment; connecting the raspi3 to the
tiny USB pins on the NEO7M was fun, but otherwise unproductive. I'm
hoping it's possible to send commands directly to the neo7m via usb
without a special chip.
