); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY BTW, I just placed another of the 9390s on line last night, using the same output of the amp/splitter as the one that used to go to the 9390 that died, and, this morning it is locked and showing both the right time and the right day of the year. This one came for less than $100 with shipping from ebay. It was sold as is, had a special connector on the rear for AC and another for DC, so, was sold as is. After finding a connector and wiring it up, it did not work. A little trouble shooting revealed a defective on/off switch. This one also has a Rubidium inside. Date code of most parts is 1994. This one has about 25 or so BNCs on the rear, so, just about every type of output is available. Not a bad investment. Here is the ebay URL for it in case anyone is interested. Regards - Mike

Most with Rubidiums and some with OCXOs. I had 3 of them running simultaneously with a Z3801A. They were on an HP antenna running through a 4 way splitter that is widely available on ebay. Two of the three locked properly and showed the proper time, however, they had the wrong, but same, day of year. I could live with that. The other one showed the correct day of year and time. About a month ago the one that showed the correct day of year totally quit lock, and I believe it also shows a low signal level, as the system check was OK. Too many other projects to play with it yet. Regards - Mike Mike B.

I have a Datum 9390-6000 with the Rubidium frequency standard inside that has been working fine for the past year or so. It requires a high gain antenna and I'm using a Symmetricom 58532A L1 antenna. With this antenna I get a "System Check OK" message on the screen. With any other of my GPS antennas I get a "low signal level" message. I have six other GPS units operating with various antennas that all work fine. While I don't get any error messages on the 9390, the unit no longer locks onto the GPS. If I look at the satellites, the display shows zero for the signal strengths for each satellite that is trying to track. I'm wondering if this is an antenna problem vs. a problem with the 9390 and is there someway to tell. I don't see anyway to do advanced diagnostics on this unit, and since the GPS receiver is a propriety unit, I can't substitute it for another model. Is there a recommended antenna that works best with this unit? Since the repair on the 9390 is quite expensive, I'm wondering if there is another way around this, possibly trying a better antenna. Thanks for your help. Mitch. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
