This is a long shot but I am hoping that someone might be able to give
me some Hints as to a problem that I am having with a Used 151-601 XL-DC
Receiver that I recently purchased. When I first fired it up it showed a
date of 1990 so I updated the Date to the current one and then went
through a 24 hour Auto Mode set up. Once the receiver went into Time
mode at the end of set up. I pushed the Location button and noted A good
Lat, Lon and elevation had been established. The LCD was showing 3D for
the most part and 5 or 6 SAT PRN's. Looking at Osc Stats I see Offsets
ranging from the 10 -10 to 10 -12, Drift 10-08 to 10-09, Phase 10-08 to
10-10 and DAC ranging very slowly from 15950 up to 16400 or so. Now the
bad news after days of operation I am still showing GPS Unlocked,
Position,  Time Unknown (Even though a Lat, Lon had been established and
UTC had been added through a Function command), Time Error and
Acquisition Error ; when I do a F73 "Show Faults" . I seem to be
acquirin
 g the satellites but not decoding their full message. I am not sure if
this is due to a mistake I am making or a receiver failure. 
Any suggestions that anyone can give would be ever so greatly
appreciated for I am at a loss and so far my web searches have been
fruitless. Thank you all for your consideration in this.....
