Hi Tom:
Does the unit have a serial port?. If so may want to try and connect it to your pc and use the Lady Heather GPSDO monitoring program. From what you describe by the LED's it is possible it has not locked, or still trying to perform a survey, or maybe a error. Usually a green solid LED somewhere indicates a lock. http://www.ke5fx.com/heather/readme.htm -=Bryan=- ________________________________ From: time-nuts <time-nuts-boun...@febo.com> on behalf of Tom Koza <wb6...@gmail.com> Sent: April 19, 2018 1:47 PM To: time-nuts@febo.com Subject: [time-nuts] Introduction & GPSDO Question Hello Everyone, My name is Tom and my amateur callsign is WB6FYR, I'm a newcomer to this group. I'm mainly interested in creating a reasonable 10mHz standard for my various pieces of test equipment here at home. To that end I've purchased and received an Ebay "Trimble Inside" GPSDO unit, described as model 57963. No instructions or manual were included with the hardware. The unit has now been powered up for the past 18 hours with the GPS antenna connected with a favorable outside view of the southern sky. I am however uncertain if the hardware is GPS locked based on the two external ACT status LEDs, the leftmost LED is solid yellow and the adjacent right LED is rapidly flashing red. The 1pps LED is flashing once per second as expected. Can anyone point me to an online manual or explain the ACT status LEDs and how to interpret those indications. Thanks very much! _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts time-nuts Info Page - American Febo Enterprises<https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts> www.febo.com time-nuts is a low volume, high SNR list for the discussion of precise time and frequency measurement and related topics.
