Re: [time-nuts] The future of UTC
Ha, you may well ask. The reason to hate DST is given to us in the southern parts of Australia, by our Queensland cousins: The problems with DST is : 1. The Cows get very confused and the farmers have problems milking them. 2. The chickens don't know anymore when to lay the eggs. it is rumoured, that the shape of the eggs may suffer. However, this has not been proven, since Queensland never had DST. and 3. most importantly, The extra daylight fades the curtains more, and as every housewife will tell you: That will never do On 22/07/2011 17:19, Jim Palfreyman wrote: Mr HeathKid, What is your reason for hating dst.

I've just read so many logical fallacies and government conspiracies I'm embarrassed for this high quality list. Let's inject some facts here. I live at 43 degrees south. At the winter solstice (June 21) the sun rises at 7:41 and sets at 16:43. At the summer solstice (December 21) the sun rises (no DST) at 04:28 and sets at 19:49. Sunrise at 04:28 is ridiculous. Including twilight it starts getting light at 3:30. Switch to DST and sunrise moves to 05:28 and sets at 20:49. Much more reasonable. Nice summer evenings too. We have DST for 6 months of the year and wouldn't swap it for anything. I understand it's different the closer to the equator you are, but for mid latitudes it really works.

For 25 years, candy-makers have wanted to get trick-or-treat covered by Daylight Saving, figuring that if children have an extra hour of daylight, they'll collect more candy. In fact, they went so far during the 1985 hearings on Daylight Saving as to put candy pumpkins on the seat of every senator, hoping to win a little favor. I would say it backfired. At least here in Rhode Island, the extra daylight resulted in the compression of the trick or treating schedule, since all the little goblins and ghouls wanted to go out after dark (to better scare the homeowners and enjoy their glow in the dark costumes), but they also were expected home by 8pm (local). Net result is less candy given out. At least that has been my experience. Proving you shouldn't tamper with time.

Re: [time-nuts] Problems with Garmin - maybe we should cut them alittle slack
Hi, first, a happy and hopefully healthy New Year to all of you. I think, some of you are going slightly overboard, in what you expect a $150 Dollar car navigator should do, I also don't believe some of you you realise what exactly it was designed to do. It is not a device to accurately shoot a missile trough somebodies toilet window and hit a specified turd in the bowl. It is designed to get you relatively easy and close to a specified designation. preferably when used in a motor car This it does perfectly well. It may be a few meters out from an exact house number, but it got you there without you having to look at the map, (or worse get your spouse to read the map and navigate you). It improves the road safety, especially at night time, when you often don't see the street names and have to slow down to a crawl with a lot of cars bunched up behind you. The mind boggles if some of you think because the GPS is not 100% accurate, The Fire brigade gets either lost, or tries to extinguish the house next door to the burning one, just because the GPS is 30m out. What you're actually are saying is: The Fire brigade is full of idiots. To sell an item for 150 or so Bucks, on can not reasonably expect it to be as perfect than another item which sells for 100 grand or more and nobody except a few government institutions can afford it. Not every instrument is mad by Agilent for a cost which is prohibitive to the normal punter. Just get back down to earth, a few years ago you had to learn how to read a map, or follow the often useless instructions somebody else gave you. Now for hardly any money, you get to your destination with least amount of effort and a lot saver than before. Regards, Horst gonzo- A GPS is a precision device. A Navigator is a consumer device. To confuse the two is to fail to understand either. A navigator IS a GPS. Surveying GPSs may use carrier phase tracking or whatever to get about 2mm accuracy. Just because it is optimized for navigation instead of location accuracy and gets about 3m accuracy doesn't mean that a navigator isn't a GPS. Note that map accuracy has nothing to do with GPS receiver accuracy. Also some mapping data has built in errors or incorrect POIs to identify the data in case it is copied.

[time-nuts] Pin connections for Datum 1130 Oscillator
Hi, I have a Datum model 1130 Double oven 10 Mhz Crystal oscillator. It has a 9 Pin D-Connector. The way it looks, it uses an external frequency adjustment. I wonder if it is a potentiometer or an external voltage. according to the specifications I found on the internet, it uses an SC cut crystal and has quite good specs. It has 2 SMA outputs and uses a couple of LH0033 buffers driving a transformer each Does anybody know the pin connections?

Re: [time-nuts] And you thought you were old
I still have an original booklet from raytheon : how to build a 1 transistor radio with a CK722. However, my very first transistor first transistor was an OC70 from Valvo (German Philips). I bought it about 1956 ,I was 13 years old then in Stuttgart Germany. It cost me 10.20 German Marks. A substancial sum then. I soldered the transistor in to a socket , so the leads would not break off. I build many different projects with it then. Now when I see one of the old black Philips glass encapulated transistors, I get quite nostalgic. But this days one hardly looks at a modern transisitor anymore.

In the 1950s, Raytheon was making tiny transistors for hearing aids to replace the pre-WW II subminiature tubes. Aside: Those tubes, developed by Norm Krim, were ruggedized and used in the WW II Proximity Fuzes, one of THE big inventions of WW II. Anyway, Raytheon was making piles of these tiny transistors, but many were not making hearing aid specs. Norm got the idea of packaging them to sell to hams to learn about transistors. If you open up one of the blue ones, there is another tiny case inside which is the real transistor. BTW, Norm is still alive and well in his 90s. -John === Anyone remember the CK722 transistor?
