Paul,
How far from the equator are you? The farther you are, the more trouble
GPS has measuring your latitude due to worsening geometry.
By the way, does anyone know what the timing effects of that will be?
Is it documented anywhere? I noticed that the GLONASS satellites have a
higher orbital inclination than GPS. Would a GLONASS Disciplined
Oscillator perform better at higher latitudes than a GPSDO?

I just tried sending various TMODE and TMODE2 configuration messages to the

surprisingly, it replied with negative acknowledgements each time so they
presumably aren't supported in this receiver.
Right, those are typically T version only commands. It should be in
the documents as a note. The earlier list of timing attributes left
out a critical one, being able to set your position to the accuracy of
the receiver. While it's probably my poor anttenna siting the various
self-surveys (Tbolt, Res-T, LEA-6T) I've done are all pretty poor.
