Re: [time-nuts] Looking for a Trimble Lassen SK-8 or SK II 5V GPS receiver
Dear Bob, In case you are looking for replacement, there is clone available for most of the old Trimble modules (Lassen, IQ, LP) : http://www.naelcom.com/ds/gps/ds_lassen_clone_series.pdf Regards, Luc -Message d'origine- De : time-nuts [mailto:time-nuts-boun...@febo.com] De la part de Bob L. Envoyé : lundi 30 mai 2016 03:55 À : time-nuts@febo.com Objet : Re: [time-nuts] Looking for a Trimble Lassen SK-8 or SK II 5V GPS receiver Hi folks, I went with plan “B” and am no longer looking for relatively recent Lassen receivers. The clock using the older Lassen receiver speaks NMEA as well as Trimble protocols. I’m building a simple ExpressPCB board in the Trimble Lassen form factor to interface with a variety of more modern receivers. A few gates and a jumper enabled logic inversion now enable the clock to use most any 5V integrated antenna/receiver speaking NMEA or Trimble protocols at RS-232 or CMOS levels. Also found a pair of Garmin GPS18x LVC 5m on ebay which will be arriving next week about the time the bare boards get here. Problem solved, correct date restored! Many thanks!

Re: [time-nuts] Trimble Thunderbolt error
Hello, The issue was known on the Thunderbold for the older firmware version up to firmware v3.00. The product will not report the correct extended GPS week number after the Feb,13th 2016. After the rollover to week #860, the thunderbolt will not make position for 2 hours, because the Ephemeris data on the GPS receiver being consider incorrect. The module will work fine after this 2 hours.

Re: [time-nuts] WTB: GPS Antenna Splitter
Hello, You could find off the shelves units from www.gpssource.com MS22 or MS24. For standard splitter www.instockwireless.com with the GPS200/201 and GPS400/401 are interesting.

Those on Ebay are rather expensive. I have two GPSDO units, and have both an older timing antenna and a new choke ring antenna (Thanks, Pete L). I already have one 2-port splitter (working well), but my intent is to connect both antennas through the splitters and a couple coaxial relays so that I can, with the twist of a switch, allow me to run each GPS from a different antenna, or both from the same antenna. I would like to gather some data as to the differences between the two antennas. I know I could switch the connections manually, but I like the idea of a switch to sort of automate the connections, and I'd need another splitter anyway. Before I go to the trouble and expense of building upon this idea, are there any comments as to the value of the project? Some questions come to mind: I'm thinking about mounting both antennas on the same mast, at the same elevation, just separated by a couple feet. Any problems that I should be aware of by putting both antennas so close together? Will that small distance have a noticeable effect when switching a receiver from one antenna to the other? Will the GPS notice the difference and want to do another survey? Thanks for your comments.

[time-nuts] SMTP with Trimble Thunderbolt-E
Hello, I need to have remotely access to Trimble Thunderbolt-E to manage it. I first sort out the physical (network) parts to get the Serial port out on the network (unit CSE-H53N from Sollae Systems). For management I am looking to use SNMP. Is there any system capable to convert the serial information from the Trimble Thunderbolt to SNMP ? Some people are talking about proxy agent. Is any can help ?
