Klaus, It would appear that you are still acquiring sats.
I would not reach any conclusions about function until the survey is 'complete'. Currently, it is suspended. I suspect it all goes back to a poor set of signals from your GPS antenna. I don't know anything about how these units 'should operate', only how they do operate when given a good GPS signal. It would appear that your units worked normally when using the outdoor antenna. Good luck.

They tracked 8 satellites with an outdoor antenna... all fine. Repowered both units, but now using an indoor GPS antenna with bad reception. REF1 is in "Locked to Ext: stabilizing frequency" mode with TFOM=3, FFOM=1 and "1PPS TI +40.0 ns relative to Ext", but it is in StandBy. REF0 is ON and in "Power-up: GPS acquisition" mode with TFOM=9, FFOM=3. Why isn't REF1 providing the 15Mhz/1PPS signal?
