The site does ship to the US and once the product is available middle June If necessary I will be glad to help. How ever we have time nuts living in Germany and some probably have bought from this site. They can log in and find out what then payment options are.Most likely you will be able to place the order and pay for it and have it shipped to you. Shipping will be E 5.90 from what I can tell. But it will be clear once the product is available. At the time if necessary I will be glad to get on the phone with you and talk you through the process.

We then do a Complex to Mag^2 to effectively get rid of any negative values, before a threshold block essentially converts the signal to a square wave (via a moving average to help with interference and noise, as well as general signal level changes throughout the day] The eventual output is a 1 kHz stream of 1s and 0's, sent via UDP (You will notice the significance of the port numbers selected - 12360 and 12377 in the flowgraph :)]. A separate application (currently using nc and stdin/stdout) looks for the Start of Minute marker, then grabs the rest of the second's data. Once completed it decodes[1] it, and sends it on to NTP via the SHM driver. This code is currently running on the same machine, but could be run on any capable UDP host. I intend to try it on a beaglebone[2], and see what the difference is. Now, I was expecting some pretty awful jitter etc, but have been rather surprised. Here are a few random ntpq outputs taken over a few hours (nothing scientific): ntpq> pe remote refid st t when poll reach delay offset jitter ============================================================================ == SHM(0) .MSF. 0 l 7 64 377 0.000 6.622 0.859 SHM(1) .DCF. 0 l 6 64 377 0.000 -3.321 0.900 *cerberus.local 192.36.143.153 2 u 15 64 377 0.061 -0.265 0.347 ntpq> pe remote refid st t when poll reach delay offset jitter ============================================================================ == SHM(0) .MSF. 0 l 13 64 377 0.000 6.932 0.193 SHM(1) .DCF. 0 l 12 64 277 0.000 -2.913 0.107 *cerberus.local 192.36.143.153 2 u 255 256 377 0.099 0.606 2.365 ntpq> pe remote refid st t when poll reach delay offset jitter ============================================================================ == SHM(0) .MSF. 0 l 10 64 377 0.000 7.062 0.146 SHM(1) .DCF. 0 l 9 64 325 0.000 7.193 3.888 *cerberus.local 192.36.143.153 2 u 174 256 377 0.099 0.606 4.162 Both radio clocks were set to noselect. cerberus was serving as a reference, and was talking to a cesium over the internet, but for this experiment was more than sufficient. The jitter and offset figures are far better than I had been expecting, and more than sufficient for numbering the seconds and Time-Of-Day, before a PPS source takes over (See [2]). They are also far better than I had been getting from one of the available modules For anyone wanting to try this, the hardware was simply my LF Antenna/Preamp [which primarily does LORAN duty, but has a 4 way splitter on the end], plugged into my 192k soundcard. Those in UK/Europe may get by with a long wire (I haven't tried it yet - my own has other duties right now), but I could audibly still detect MSF with it when I did a quick check] If HF ever recovers here, I shall have a go at detecting and decoding the MIKES IRIG station in Finland on 25 MHz. I'm also trying to write a flowgraph for RBU, but that it proving a challenge (it uses 100Hz and 312.5 Hz tones to indicate 0 and 1 in the time code, but even with SDR techniques it's difficult to separate the two, not to mention it's far less powerful and further away than both MSF and DCF from me. Iain [1] At present, this code is a lash up. It doesn't check for leap seconds, will break come the 3rd weekend in October here in Europe, and doesn't check Parity. That said, the decoding is so solid for me, that even when (usually the DCF side) decodes things incorrectly it's so far out, NTP just laughs at it. I'm lazy. The RF code was far more interesting to write than "is this bit set, is that bit set ?" :) [2] Said beaglebone currently has a PPS input from an Austron 2100 locked to Anthorn, but needs an internet host to set the time-of-day ------------------------------ Message: 4 Date: Sun, 18 May 2014 09:50:18 -0500 From: "Jason Rabel" <ja...@extremeoverclocking.com> To: <time-nuts@febo.com> Subject: Re: [time-nuts] iTrax130 Message-ID: <000001cf72a8$7e2e9d10$7a8bd730$@extremeoverclocking.com> Content-Type: text/plain; charset="us-ascii" > Just got this board from a Chinese ebayer, but unable to find any > document about the pin-assignment. One of the ebay sellers had some PDF links, but also said it is the same pinout as a Trimble Resolution T. It seems to fit the same shape and header location... But be cautious...

As your data shows, the jitter is low enough to make it worth doing. We get so used to GPS (that corrects automatically) that we forget about doing it for VLF. I have a couple of local VLF based NTP servers that have issues because they don?t have the delay set right.
