); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] RETRY Hi Mitch,
What cable are you using? Units used to ship (when I was selling them ) with the Trimble Bullet II antenna. If your cable is dropping more than 30-35 dB at 1575MHz then you will have problems. You might want to check your cable and connections, especially if the antenna is outside. Let me know how you get on.

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 -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ 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.
