Re: [time-nuts] Trimble Thunderbolt NMEA ?
The code is in C and Silabs has small dev kits (Toolsticks) that cost $10 to which you need to add $18 for the programming dongle. A little more expensive than an Arduino, or less, depending on where you buy it... To that you need to add a MAX232 (or two serial-TTL adapters at $4 each or so on ebay) and you are in business. Total cost about the same as a dedicated GPS receiver with antenna and NMEA output. Choose your poison :) Didier KO4BB On March 3, 2015 10:23:56 PM CST, Chris Albertson wrote: >Is the code in C?

Is the code in C? If so I bet it would run on some development board. No need to make custom PCBs.

Navigation receivers that output 1pps and NMEA data are a dime-a-dozen now, under $50. Go look at what is available from the likes of SparkFun or Adafruit. For disciplining the clock in in the computers running your WSPR and OPERA software even the cheapest receivers greatly exceed the required timing accuracy. (NTP across the net is sufficient for these applications.) What I am doing is using a BeagleBone Black and a Jackson Labs LTE-lite receiver as my household stratum-1 NTP server and backup 10MHz and 1pps reference. In the same enclosure I am mounting my Trimble Thunderbolt to use as my primary 10MHz and 1pps reference. Fan-out of these signals is accomplished using the TAPR TADD-1 and TADD-3 distribution modules. All of this is easy to accomplish with a minimum of hardware and software hacking. I am mounting everything in a 2U rack case into which I plan to incorporate a battery backup. By time-nuts standards this is pretty mundane, but still represents a very credible level of performance from a ham-radio and general timing point-of-view. -- Brian Lloyd 706 Flightline Drive Spring Branch, TX 78070 br...@lloyd.aero +1.210.802-8FLY (1.210.802-8359) ___ 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.
Re: [time-nuts] Trimble Thunderbolt NMEA ?
Tim, It shouldn't be too hard to modify the code for my Thunderbolt monitor to make it into a TSIP->NMEA converter. The last version of the kit has a uC with two serial ports. I m out of the kits at the moment but I have a few spare boards left over. Don't have time to write the code at the moment, but I have released the source code for the kit.

Re: [time-nuts] Trimble Thunderbolt NMEA ?
What NMEA sentences does this device accept? It would not be hard to make a small uP device like say an Arduino that would output those NMEA sentences using data it gets from the TB.The data rate is very slow so even the smallest uP would work. None of this NMEA stuff is very time critical either. It's the PPS that does the timing.

Can you elaborate on what you are trying yo do? Hi Didier, I' building a multi frequency beacon based on QRP-labs U3 beacon kit. It has the ability to discipline its oscillator with a PPS input and, using NMEA input, set and maintain time and location for exact control of WSPR and OPERA modes of operation. As it currently only accepts NMEA input I was wondering there was a way to get NMEA out of a thunderbolt. I've lodged an RFE with the developer to add TSIP support to the U3, but I don't think that's going to happen anytime soon. I'd rather use the Thunderbolt as the time and PPS source since its way more accurate than the LEA-M8FGPS module that optionally comes with the kit. I'd like to use the U3 as the basis of beacons all the way to 10GHz and the Thunderbolt is a superior device for locking such things and supplying the base 10Mhz to lock the appropriate LO's. thanks Tim -- VK2XAX :: QF56if23 :: BMARC :: WIA :: AMSATVK ___ 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.
Re: [time-nuts] Trimble Thunderbolt NMEA ?
I'll second that. I had a sailboat a while back with about 1/2 dozen NMEA devices off all kinds (GPS, Water speed sensors, Wd speed and direction, magnetic compass and so on). All feeding the nav system. NMEA was designed for marine navigation networks. Th spec is really poor for timing in that the data is valid "within the current second" That means that it could be up to one second old.

Re: [time-nuts] Trimble Thunderbolt NMEA ?
Tim, NMEA is normally used for navigation. It would seem unlikely that anyone would want to use a Thunderbolt for navigation. Can you elaborate on what you are trying yo do?

Re: [time-nuts] Trimble Thunderbolt NMEA ?
Hi Tim, probably not the answer you are looking for, because it's a piece of software and not a device, and it doesn't output NMEA, but maybe it can still be of some help https://github.com/mpbraendli/trimble-thunderbold Matthias HB9EGM On 26. 02. 15 05:11, Tim wrote: > Hi all, > > Is there a way to get NMEA instead of TSIP out of a Thunderbolt ? > > Failing that, is there some translating device that I can insert between > the Thunderbolt and another device that is expecting NMEA ? > > thanks > > Tim > ___ 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] Trimble Thunderbolt NMEA ?
Hi all, Is there a way to get NMEA instead of TSIP out of a Thunderbolt ? Failing that, is there some translating device that I can insert between the Thunderbolt and another device that is expecting NMEA ? thanks Tim -- VK2XAX :: QF56if23 :: BMARC :: WIA :: AMSATVK ___ 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.
