The optimum solution is a phase lock loop. Whilst building an FLL is instructive/educational, if you want the best GPSDO performance you should really use a PLL. Perhaps it depends on how you define a "good" approach. If you're looking for the very best you can get then it probably isn't, but I don't recall that being claimed in the first place. However, one of the attractions has to be the simplicity of the circuit and the fact that something offering reasonable performance can be knocked up very quickly. Without the divider and buffers, the circuit proposed by Bertrand Zauhar, VE2ZAZ, in his QEX article reduces to just three ICs. It may not be optimum but it must be a strong contender for the best you can get for very little effort.

I'm interested in both WWVB and GPS. WWVB is 60 KHz which is the 500th harmonic of 120 Hz.500 is a big number, so maybe that's not a serious problem. I don't have any WWVB gear right now so this part is just academic curiosity. On the other hand, that fixture is only 6-8 ft from a couple of GPS antennas. This seems to be one of those areas when yer pays yer money and takes yer chance! "Normal" fluorescents can wipe out LF and well into MF, say 3 or 4 MHz at least, that harmonic ratio is no security. In a previous house I had several fittings in a garage 6 or 7 metres from the house, admittedly old and buzzing well, and if I forgot to switch these off the RFI wiped out LF/MF totallyat least it was easy to spot and fix:-) We had fluorescents and CFLs in our recent urban apartment but backround RFI was so bad to start with it was impossible to detect any difference with lights on or off. The more recent house we have now also has a couple of fluorescents in the garage, but in much better condition than those mentioned above. These also generate interference but nowhere near as bad as before. I've also had experience of nearby fluorescents where there didn't seem to be any noticeable RFI at all. I much prefer the light from fluorescents, over incandescent bulbs, for a lab or workshop environment but do try to avoid them if possible. CFLs though are not just "normal" fluorescents wound up small. In place of the iron cored choke they use an electronic ballast. I'm no expert on these but assume they can be considered to have similar characteristics to a switch mode power supply, and they operate at a much higher frequency than 50 or 60 Hz, I've just seen one example quoting 34 KHz. Again, some appear to be better behaved than others but for anyone wanting to receive on LF/MF, and hence WWVB, I would recommend avoiding them like the plague. The RSGB mag RadCom has carried reports on some of these for the EMC page. I don't have these back copies to hand but there may be copies of the articles online somewhere. I'm sure a Google check would provide more info. Another item to avoid, or at least be wary of, is the dimmer switch for incandescent bulbs. These chop the incoming sinewave by varying the switching angle and can again generate severe LF/MF interference. I've heard bad reports of these but have also used LF loops just a few feet above them with no effect, so again mileage varies. Many domestic appliances, TVs etc, now carry switch mode PSUs which are permanently on unless disconnected from the mains. These are becoming increasing sources of LF/MF/HF interference and there's been many reports of severe interference traced to such items. Then there's good ole "Broadband Over Powerline" (BPL), another great source of interference below 30 MHz. So that's the sort of fun you might expect with WWVB:-) Having said all that, I would not expect there to be any problems from either type of fluorescent with GPS equipment operating in L band, providing good RF practice is followed. Fluorescent tubes interfering with low level 10GHz microwave signals is a well perceived phenomena but this is due to the the ionised gasses being in the transmission path. It might be an interesting area for observation but would suggest changing the antenna or checking wiring if a problem were observed. If direct RF interference is unlikely, but there's always the possibility of noise on power feeds with any equipment. Proper screening and grounding should avoid any issues. With GPS timing, the only low level signal is the GPS signal itself, signals out of the receiver module are much higher amplitude so much less liable to the sort of interference being considered. Power line conditioning is worth considering for any lab environment though, just because the amount of mains borne crud is increasing all the time. Perhaps a Faraday screen or three might help too:-) regards Nigel GM8PZR ___ 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.

The following is just one quick example from a google search and came from... http://www.endruntechnologies.com/stratum1.htm What is Stratum 1? In the world of NTP, stratum levels define the distance from the reference clock. A reference clock is a stratum-0 device that is assumed to be accurate and has lttle or no delay associated with it. The reference clock synchronizes to the correct time (UTC) using long wave radio signals, GPS transmissions, CDMA technology or other time signals such as WWV, DCF77, etc. Stratum-0 servers cannot be used on the network, instead, they are directly connected to computers which then operate as stratum-1 servers. A server that is directly linked to a stratum-0 device is called a stratum-1 server. This includes all time servers with built-in stratum-0 devices and those with direct links to stratum-0 devices such as over an RS-232 connection or via an IRIG-B time code. The basic definition of a stratum-1 time server is that it be directly linked (not over a network path) to a reliable source of UTC time such as GPS, WWV, or CDMA transmissions. A stratum-1 time server acts as a primary network time standard. - See what he makes of that :-) regards Nigel GM8PZR ___ 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.

There are intervals between events, that we refer to as "time" or the "passage of time", and we choose to allocate a unit to this, the "second", just as we choose to allocate units to distance and mass. Distance and mass, however, are a bit more user friendly, in that generally there is at least the possibility that a given distance or mass will remain obligingly the same for long enough to enable a repeat measurement, albeit within certain tolerances. This doesn't apply to time, nor to anything else once time becomes involved, which in itself, of course, makes the above statement extremely suspect:-) With time, it's those intervals between events that we seek to measure with ever increasing precision, and great fun it is too:-), but however "repetitive" given events are the "same" event never occurs twice and neither does the same interval. This may all seem boringly obvious but, since "time" depends for it's existence on these patterns of events and the intervals between them, the question as to whether time itself really exists as a quantity may turn out to be not quite so trivial after all. regards Nigel GM8PZR ___ 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.

When the receiver boots it looks at the Option List in the receiver ID to see which options are active. Motorola liked to pretend that the timing and carrier phase receivers were more expensive because of specialized code, but in fact this was not the case. The code was always there, but the receiver would not use it if the option was not present in the receiver ID. --- I take it that means a flash upgrade would just have to modify the receiver ID, or even just the option list? :-) ___ 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] Oncore VP problem
); SAEximRunCond expanded to false Errors-To: [EMAIL PROTECTED] Hi All I'm trying to set up a supposedly NOS GPS development kit, similar to the old Motorola evalution kit, with an Oncore VP mounted on an interface board fitted with a 5 volt regulator and MAX232 interface chip. Running WinOncore12 under WinXP I can talk to the module ok, enter location info and get it to return it's ID etc, but other than that I can't get it to do anything. I've discovered from the VP command set that it goes into idle mode after a self test and needs a "position fix mode" command to put it back into "fix" mode. Unfortunately, although the module acknowledges the command it reports that it's still in idle mode. I'll dig out a DOS PC later, and try an earlier version of the software, but if anyone's come across this before I'd be grateful for any tips as to how I can kick it back into life again. regards Nigel GM8PZR ___ 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.
