My subj Nortel Trimble GPSTM had been working well for about two years. Changed QTH by about 20 miles, reconnected with same power supply, coax and antenna. Cannot see any GPS satellites or 10 mHz output (9.8MHz on 8X Chip is present and front panel LEDs show the unit responding to software commands as before).
Lady Heather and tboltmon both report ROM, RAM, OSC, POWER, EEPROM and ANTENNA OK thru RS-232 interface. Replaced bullet antenna anyway - no change. 5VDC present at antenna and it draws about 33 mA. Other local GPS devices (two vehicles and one EarthMate) achieve 3D fixes from ground level antennas. Performed warm, cold and hard resets (erasing former GPS position), min elevation set at 15 degrees. Survey starts, but doesn't proceed. All eight satellite status lines show yellow and zero's across. Undisciplined, No GPS time, no Posn. Start date is reported as 07 April 2019 week 2048. The unit performed flawlessly at previous QTH frequently showing good signals from 7-8 GPS satellites. What happened? Do I have a broken box that cannot be detected by software control/reporting programs? Thanks in advance for any ideas. 73, Mike - W7GW _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
