Re: [Elecraft] temperature sensors and "convert" -- totally off topic
Hi Willis, Whitworth is not dead yet!!I believe it is still used on cameras for the tripod mount. Want a mess to play with...

At first, everything is translated back to your native language and then to thoughts. Eventually your “knower” translates the words (or morse sounds) directly to thoughts, bypassing the translation to your native language.

Re: [Elecraft] temperature sensors and "convert" -- totally off topic
Since Eric seems to be on vacation or otherwise indisposed ... With full credit to Richmond Johnson, a colleague at work and retired USAF Col, I think the problem with "going metric" is that we all have a "Knower" inside our head, as he said. I "know" what a mile is. I have body parts that help me know what an inch, a foot, or a yard are. On the highway, I can probably tell you when we've gone a mile to within maybe 200-300 ft. I "know" what a pound is, give me a brick and I'll likely hit it within a few ounces. Yes, my Knower knows what an ounce is too. Ham radio as a teen exposed me to metric ... 80 and 40 meters. While in uniform in SE Asia, I learned metric for good. It took awhile for my "knower" to know what a kilometer was without translating to miles, but it did, and now I just "know" what a kilometer is, same for meters, centimeters and millimeters. I "know" how hot my KPA500 is when it says "60C". I have to think to relate that to deg F, and I don't care anyway. At one point a number of years ago, CalTrans began putting both miles and km on road signs. I don't think there are many left. It's probably going to take a generation or two dying off [one might be mine :-))] before the move to metric will accelerate. It's moving very slow now, furlong by furlong, it does seem really slow. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org On 6/22/2014 3:56 PM, Don Wilhelm wrote: Well, that may be more possible than many years ago when a switch to metric was proposed.

If you compare the old centigrade scale to Celsius they differ in terms of the value of freezing point versus triple point of water. The original Celsius scale was actually the reverse of the centigrade scale where 100 was freezing point of water and 0 was boiling point of water. But, after the death of Anders Celsius, the end points were reversed to match the centigrade and the two scales were the same until the 1950s when they received slightly different definitions with the meaning of the 0 measure on the scale. 73, phil, K7PEH* * more of a physicist than an engineer. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com

Re: [Elecraft] Temperature Sensors
I don't see that it matters. If you learn the normal operating temperatures of your K3 in C then knowing those numbers in F doesn't add any information. If the normal PA temp is 55C during a contest and you see it at 60C then you know you should back off a bit. The only time you need to convert is when you calibrate the temp sensors. 73, Brian K0DTJ > On Jun 22, 2014, at 7:30, "Jim Miller" wrote: > > I understand the metric system.

Re: [Elecraft] Temperature Sensors
Knowing the formulas for conversion means that you can do them in your head. The arithmetic is easy. Actually, the arithmetic is trivial if you allow a slight error in your result. Formula for going from F degrees to C degrees is: C = 5/9 * (F - 32) Or, five-ninths of result of subtracting 32 from F degree reading. But, 5/9th is close to 5/10ths for rough, in the head, calculations and 5/10ths is 1/2 or one-half. So, to convert degrees F to degrees C you do the following: subtract 32 then divide the result by 2. Easy to do in your head quickly even while carrying on a QSO with someone in Celsius land. Example, your outdoor temperature is 85 degrees F (meaning, you don't live in the Seattle area) so you subtract 32 to get 53 and divide by 2 which is 27.5 degrees. The actual value is 5/9th instead of 1/2 (5/10ths) so the correct C reading of 85 degrees F is: 29.44 (and, not many of us can feel the difference in temp of just 2 degrees). You can even get used to the idea of adding in a fudge factor due to the error in the calculation that might range from 1 to 3 degrees depending on the range of the F value. The actual error is close 6 percent (that is, result is ~6 percent too small using this trick) so just remember the 6 percent fudge factor). For C to F just do the opposite: double your C temp value and add 32. 73, phil On Jun 22, 2014, at 7:30 AM, Jim Miller wrote: > I understand the metric system. I have to convert everything.

Re: [Elecraft] Temperature Sensors
Thanks for all the helpful suggestions. Yes, I learned all the temperature conversion formulas in high school chemistry. Unfortunately, I don't live in the metric universe, I just visit it. With all the complicated things the K3 firmware does, it seems that Celsius to Fahrenheit would be an easy and convenient feature to have. 73, Ron, K5HM k5hm@gmail.com www.qrz.com/db/k5hm -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Kevin Stover Sent: Sunday, June 22, 2014 8:12 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Temperature Sensors I ditto the use of Convert.

Re: [Elecraft] Temperature Sensors
Ron, Yes, but you have to do a bit of math. There is a simplified formula that does not require one to remember whether to add or subtract 32 degrees. That method has to do with the fact that the two scales coincide at - 40 deg. So add 40 degrees to the reading (whether that be degF or degC), then if converting from degF to degC (you want a lower number), multiply by 5 and divide by 9. If converting from degC to degF (you want a larger number), multiply by 9 and divide by 5. Lastly subtract 40 and you have the result. have fun with it. 73, Don W3FPR On 6/21/2014 10:29 PM, K5HM wrote: Anyway to get the temperature sensors read out in Fahrenheit? 73, Ron, K5HM k5hm@gmail.com www.qrz.com/db/k5hm __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to w3...@embarqmail.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
