[time-nuts] New NTBW50AA

[Mark C. Stephens]

a) Hit s then s again in LH. (survey)
b) something else caused red light (bad osc?)

Adjust unit to correct UTC and co-ords may speed up.

Where is the screen shot?

Hi

If it's trying to get a position *and* it goes below 4 sats due to antenna location, it will go to the red light mode. Once it's got a position it will hold in there with one sat. The modern nav GPS's are much more sensitive than the older GPSDO's, so you will need a better antenna location for them than for a new hand held.

I've got a screen shot of the startup, after about 15 minutes the green LED went on, indicating lock, but after about a half hour, it went out and the red light went on indicating a fault according to the book I have.  I turned it off after doing a screen shot.  I'll post them later.
