Re: [Elecraft] OT: 24 HR stand-alone shack clocks
For decades I used a homebuilt LED shack clock using a GI clock chip AY5-1224. It used the mains frequency for time keeping so the long term accuracy was good. Recently it became faulty and I could not get a replacement chip, so I decided to build something similar but more modern. (I do have a clock that is synchronised to 60KHz MSF but it is local time only, not UTC). I wanted something that would just give me auto setting, choice of UTC or Local time with auto DST. A bit of overkill for a 4 digit shack clock, but I used an Arduino, a GPS module, and an IR controller to switch modes etc. I did try it without the GPS conditioning but the RTC I had was very poor and even with calibration routines was less accurate than my old mains frequency clock, so I went for GPS which gave me auto setting as well. Nobody in their right mind would probably want to duplicate it, but anyway I put the details on: http://sourceforge.net/projects/arduinoledgpsclock/ Still to put it all in a box, but it works great. Full disclosure: I am a time nut! ;-) 73 David Anderson GM4JJJ > On 27 Nov 2014, at 00:25, Bob wrote: > > I built my own 24 hr dual zone station clock.

Re: [Elecraft] OT: Last post on time subject
The best timekeeper in my opinion are the solar powered watches that get their time via GPS (ex: Seiko Astron). You never need to make any adjustments for where you are. But if you like analog displays (hands), the cost is enough to get a really nice radio. And some with 39 time zones around the face. Of course, these may be relatively useless if the satellites are hit with a sufficiently large mass coronal emission.

Re: [Elecraft] OT: Last post on time subject
Actually, the state of Arizona where we live, is ahead of most of the rest of the world in recognizing that no daylight is actually saved by "Daylight Savings Time." Hence, we don't participate in the nonsense. Regrettably, Apple thinks that we should, so turning on the automatic setting also turns on (M)DST and places me in Colorado. Then the error is greater than one hour. If I leave it off, in has me in Phoenix (I'm actually in Tucson). If the phone was really "smart", it would know better.

Re: [Elecraft] OT: Last post on time subject
You folks with your fancy watches! I have an inexpensive Timex Expedition that I have had for about 3 years now - the one before it lasted over 5 years. The only time I have to set it is the changes between standard and daylight saving time. It is quite accurate - I check it against WWV about once a month and it has never been off by more than 2 seconds. I replace it when the battery dies or the plating on the edges of the back wears off. My Seiko sits in the drawer and shows the correct time twice a day:-) . The battery needs to be replaced every 4 to 6 months - it looks nice, but I don't use it because of the battery life. 73, Don W3FPR On 11/27/2014 12:31 PM, Nick Kemp wrote: I have the Casio Waveceptor which sync's with WWV each night as well.

Re: [Elecraft] OT: Last post on time subject
"The battery needs to be replaced every 4 to 6 months - it looks nice, but I don't use it because of the battery life. " That is why I went with the solar watch. I got tired of watch batteries dieing in less than a year. I like analog dials. The rummer is that as analog watches age, the lubricants evap/deteriorate causing greater strain on the "motor" and that is why batteries don't last in older watches compared to newer. Or is it that watch batteries aren't as good as they used to be? I periodically look for a reasonably priced, good, self winding mechanical watch...but do I really need another?

The tones [500 and 600 Hz on alternate minutes] are transmitted at 50% modulation. The second harmonic of the tone on 10 MHz is about 15 to 18 dB below the fundamental tone on my P3 using the dBm scale. There is selective fading visible on the tones. The third harmonic is roughly another 15 dB below the second harmonic, and it fades more. At times, I can discern the fourth harmonic on the waterfall in monochrome mode, but can't see it on the spectrum display. The tone fundamental and each of the harmonics are surrounded by the sidebands of the 100 Hz sub-carrier and the IRIG-H time code. The striking part for me is the difference between 2.5/20 MHz and the other three. 2.5/20 are very clean, no tone harmonics, and the 100 Hz sub-carrier is where it should be and nowhere else. When I've listened to WWV (not often), I hear distortion. They're a Standard for Frequency and Time, not high futility. :) The modulation that is generated at Ft.

Re: [Elecraft] re K3 timekeeping
Because the Elecraft receiver is not designed to sync with those multiple time signals, it is only capable of receiving them, and you can use them to sync the time with the Elecraft RTC. A receiver is not a watch! The main difference is quantity of the precision crystals required to maintain a few seconds per month accuracy that can be purchased. Timex can easily purchase them at a low price based on an order of 10,000 or 100,000 or even 1 million. Elecraft could only swing a deal on a purchase quantity of 100 or 1000. The quantity pricing difference is extreme. The K2, K3, KX3 are known for having fine receivers, that does not mean they are also precision timepieces. The RTC is meant to be an aid to logging when no other means is available. When working in the home shack, use computer time or some "Atomic Clock" to provide you with accurate time. When operating portable, set the Elecraft clock to the correct time before your outing. It will be sufficiently accurate for logging purposes over the weekend event or even the weeklong event. Remember "logging accuracy" rather than precise time to the nanosecond. Alternately, wear your Timex (or whatever) and ignore the Elecraft gear clock. If I want to know the time, I instinctively look at my wrist, it is a habit developed over many years. It is much quicker and more reliable than dialing up the time on any of my radios. 73, Don W3FPR On 11/27/2014 4:58 PM, Barry wrote: Don Wilhelm-4 wrote The K3 RTC depends on the crystal and the associated capacitors.

[Elecraft] LaCrosse Tehcnology UTC Clocks, again.
My experience is that those of the same model number stay in synch. Had a pair of older LaCrosse clocks of identical model number which kept time in synch with each other for years until the POS Ray-O-Vac batteries leaked and messed up things inside both of them. Now have the two latest purchases running and they have been in synch since they got the signal from WWVB. A third one of a different model number (the model that does not "do" UTC also got the synch signal but is about .5 seconds off. Curious. For those of you interested in horology (not the study of streetwalkers, despite the name) Scientific American has issued a magazine-style publication which goes into some of the more esoteric aspects. A decent introduction. If you are of "a certain age" listening to the Chambers Brothers' "Time has Come Today" whilst reading the SA work is satisfying, relatively speaking. Now back to getting the mercury-ion thing cooking...(HI!) 72, Tim Message: 7 Date: Wed, 26 Nov 2014 22:34:06 -0800 From: Eric Norris To: Richard Solomon Cc: elecraft@mailman.qth.net Subject: Re: [Elecraft] LaCrosse Tehcnology UTC Clocks.

But..

Re: [Elecraft] re K3 timekeeping
Don: I think there may be a design error here. First clock crystals of the variety used in the K3 are dollar items in qualities of one. I have bought them in 1000 piece quantities for 50 cents. They are available from many vendors. Second the K3 design places a 33pf capacitor (C60) on the high side of the crystal to ground. However the clock chip manufacturer (see the data sheet at http://www.nxp.com/documents/data_sheet/PCF8563.pdf) suggests a 5 to 25pf NPO variable at this node. They also specify a maximum of 25pf on the node so the 33pf fixed value is actually out of spec. Furthermore if the 33pf cap is not NPO or COG grade it will have a poor temperature coefficient. This could easily explain the wide range of accuracy seen by users. I would hope that Elecraft would offer a 5-25 NPO trimmer upgrade. When, properly trimmed, we should be able to get the same accuracy as that $10 watch. 73, Fred, AE6QL -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Don Wilhelm Sent: Thursday, November 27, 2014 2:33 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] re K3 timekeeping Because the Elecraft receiver is not designed to sync with those multiple time signals, it is only capable of receiving them, and you can use them to sync the time with the Elecraft RTC.
