Howdy, Folks... I just joined today and I have a question... Namely, how do I determine the proton precession frequency for my area? I checked the NOAA...
... Bear, What you're looking for is the gyromagnetic ratio for protons which is 4.258kHz/G(auss). Now if I could only figure out what the units of your Total...

Joseph, Thanks for the reply. The total intensity at my location is 35,209.35 nanoTeslas. Sorry not to have included the units. 73, 'Bear' NH7SR ... is...
... Bear, Okey-dokey. Since we're talking about a low permeability world, that is, mu = 1, there are 10^4G per T(esla) and with 4.258KHz/T you should be seeing...

Joseph, Ah, so... at least now I know where to look! Thank you very much! 73, 'Bear' NH7SR ... 35,209.35 ... that is, mu = 1, there are 10^4G per T(esla) and...
With the current seismic activity going on re Mt. St. Helens... Have any of you noticed anything out of the ordinary showing up on your magnetometers? 73, ...
I have noticed something but not in the magnetometer area of things. However what I did get I think may just be a fuke reading trend but funny how at the time ...
It's a gieger counter with a large detector tube so I see all the back ground stuff coming in from space and so on. Just before it flipped it's lid my normal ...
Nevertheless it does make for an interesting coincidence... assuming that it is coincidental. I'm planning to run both a ULF receiver and a magnetometer into...
I found it interesting to that the one time something big happens that at the same time and the timing of event seem to match up. If it is just a billion to...

Lloyd, What might work is to load that disk in as a "raw" file in Cool Edit. It's an audio editor but in "raw" mode it can read just about anything as if it...
Lloyd, That old VLF radio was probably configured to use a whip antenna about 20' long for the higher ranges and a long-wire up to 200' long or so for the...
This radio was over 100 pounds I remember that very clearly! It was built to work with a transmitter of about 5 Kw as I found out later, and some of the heavy ...
At 1.5 KHz you could use an audio FFT to watch it when tuning up etc. A good one (generally useful and free) at : http://www1.ocn.ne.jp/~tuner/tuner_e.html ...
Jack, Looks like a nice program. I have a variety of programs that I can use for the same purpose with resolution down to 0.01 Hz. For finding a periodic...
Thanks "Bear" I particularly like T3. Boy, that would have been useful 35+ years ago when I was using DSB to measure the Q of acoustic cavities. (put one...
Hello and thanx for accepting me to this group so quickly! A little background on me, im currently in college in my last year of electronics, and for our final...
As far as using a HMC102x series part, it needs a lot of Set/Reset current as compared to the HMC105x parts. How accurate of magnetic heading are you trying to...
We are looking for a precision to the degree, on a 360 degree scale obviously. It would only need to be on 2 axis, provided that that it can give us that 360...
Dear Friends, next weekend (on October 29th & 30th) there will be to Trento (Italy) the 2th Italian Amateur Radio Astronomy Meeting. This event is hosted by...
The only difference between the HMC105x and the HMC102x is the Set rest current is higher in the 102x series and the 102x series is a little more senstive, 8.5...
John James: I would be pleased to receive an electronic copy of your Excel worksheets relative to Honeywell HMC1002. I am using a couple of HMC1001, where I...
i'm a university and handling a project of magnetometer. i hope to built a full feature magnetometer which measures magnetic field and directly shows the...
... For data storage look at Secure Digital or MMC memory flash cards. They use an SPI interface which is much easier to use than Compact Flash and other...
