Hi Tom,
I've done that inadvertently, using an M12+ with a totally (by several
miles) wrong hold position.
The results are astounding, the 1PPS goes completely nuts. Variations of
1000's of ns from 1PPS to the next. I would have expected the M12+ firmware to
be much smarter than that.
I don't remember if I had to turn off TRAIM to get an output at all.
bye,
Said

A fun experiment would be to set the position manually at different
levels of [in]accuracy (say, +/- 1m, 3m, 10m, 30m, 100m) in
lat, lon, and/or alt to graphically see the effect it makes on both
1PPS time offset and 10 MHz frequency stability.
