I got one of these: http://www.ebay.com/itm/Trimble-GPS-Receiver-GPSDO-10MHz-1PPS-GPS-Disciplined-Clock-with-rs232-port-/252162780444
but the PPS output is bad. Funny becaue the PPS LED is working just fine. The 10MHz looks okay (the counter says 10MHz with a Fury ext-in). This unit emits a selection of UBX messages which while not impossible to decode is bit harder than just looking for "GGA" and plucking out two fields should you want to continuously monitor the GPS. UCenter works just fine but the GPS, as shipped, is read-only. Like last time you send me a prepaid shipping label (for a US address) suitable for a USPS flat rate medium sized box (~$13.45) and I send the GPSDO (to a US address). Notable points: 0) The seller gave me a refund but said keep the GPSDO. Economics at work. 1) It does not come with a power supply (12V,2A) or antenna. 2) It does come with three SMA to BNC adapters. 3) The 1PPS doesn't work (DB9 or SMA). It will light a random LED. Barely. 4) I have too much of this stuff lying about and trying to fix one is of no value to me. Please contact me OFF list if you're interested. _______________________________________________ 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.
