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=20 flat' debug errors on SL SR correction. This is all the NEO7M seems willin= g to provide at the moment; connecting the raspi3 to the tiny USB=20 pins on the NEO7M was fun, but otherwise unproductive. I'm hoping it's pos= sible to send commands directly to the neo7m via usb without a special chip= =2E RSNTP is running on the SL pc. 73 Joe > > 73, Markus > > > > -----Urspr=C3=BCngliche Mitteilung----- > Von: Paul Nicholson > An: rsgb_lf_group > Verschickt: Sa, 7.
