If REF-0 is the only one that can output the data that would certainly put
me in a shot myself in the foot position wouldn't it?:-)
However, we do know from Arthur that REF-1 will operate stand alone, so
assuming you haven't got a faulty unit, which I suspect is pretty unlikely,
another option might be that data is only available from the currently
"active" unit, which I believe defaults to REF-0?, although both units would
presumably need to be conditioning all the time to maintain the "redundancy"
Stewart is probably going to be best placed to answer that question, given
his degree of experience in operating the two together, and it would
certainly be interesting to hear his conclusions.

Sorry if these comments are a bit naive, but this is my first exposure to
I've got mine powered on and connected to the antenna. After referring to
Stewart's original post (once again) I've managed to download HP's SATSTAT
and get it running. When I connected to the REF-1 unit (with the
receiver) all I get is comms errors. But when I connect to REF-0, Satstat seems
quite happy. It's reporting the unit as a Z3812A. Is REF-0 the only one you
can connect to, or is REF-1 mute till it's happy with the GPS receiver?
The mode says "Power-Up: GPS Acquisition", so I guess that's OK. I think
things are progressing. It's attempting to survey, but reporting
"Suspended: poor geometry". I suppose with a little more time this will work itself
out? It seems to be slowly tracking more sats, as it's now up to 5.
I wonder if there's a way to shortcut the survey process using Satstat?
I've got a 48 hour survey done on this antenna with the LEA-6T, so I should
be able to input those figures, right? I'll see if I can find anything in
a Satstat manual I found.
