Tailfeathers hurt? Bill in a Bind?
Trying to get optimized and eliminate noise?
Don't Quack Up! Buy or Rent a Frustration Filter.

How useful is that Trifield EMF meter, and what is the best setting? And how does it compare to a portable AM radio?

(This is my Trifield Air Ion Detector. I know they make good stuff.)

My experience with the AM radio is it can get you in the area, and I located some with it... but the Tri-Field is great for tracking direct to the source... I can walk right up to the device with it... now that depends on where and what the device is, but it's how I know my remaining intermittent noise will take a bomb, arson, rifle or similar to eliminate ...

Settings? I dunno... I first determine if it's Electric, Magnetic, or RF... for Magnetic, I change between the two scales as needed--- whatever... walk around with it, and a few seconds have a line, a few more seconds a general direction, then just a matter of walking that direction, watching the meter indications.

Electric and RF are detected out of the Top of the unit... just point in a direction and "follow the box" watching stronger meter levels... for magnetic more or less depend on 'meter' readings to determine direction and location, takes a bit more walk around, and you follow the 'stronger' readings... really fun when you've got more than one source.

That's about it for 'nearby' stuff.... those 'distant' or different sources,  I guess you'd still have to infer. You probably can do nothing to mitigate a Submarine Comm station, or a Pet fence or Robot Mower, but at least you can determine the source.

The Tri-Field is supposed to be good at tracking GHOSTS also... see it on those weird TV shows all the time...  I can't validate that, however... .

The Little Signal Generator BlitzorDuck shows works well at the preamp side.... just connect a scope probe to it's output, lay it on the antenna, for example and adjust the output freq to "beat down'  or mix with an incoming persistent signal.... you can sometimes nail it's exact freq doing that.... fairly quick and easy, if that's desired. Watch either with oscope, or on the Signals GUI... it works, if anynone's interested.  Suggested you get one that you can vary the freq on directly without stopping, and punching in more numbers, The Duck tells me that one doesn't work that way.  (Gotta Trust The Duck.) He says he copped it at Goose Gaggle Garage Sale while their beaks were turned.

Hi All, The H field amp and a couple of inches a of coax with just the centre connected and 25 metres or so of cat 6 cable makes a very good probe for wandering around the house and close by! Easier if you have someone to watch the screen.

Blitzortung History...
The Untold Story...

Back about 1896, inspired by Hertz, Franklin, Galvani, Marconi, Popov, Volta, and others,
my Great-Great-GranDuck Tesla Drake discovered that when a lightning rod was connected to a frog's bottom,
and lightning was nearby, not only did the legs jerk, but the frog could ring a bell,
thus alerting folks of lightning in the area.
...the very first Blistered Tongue Lightning Detector system...

...and Great-Great-Grandma opened the First Fast Food Fried Frog Leg restaurant.

Later, as the 21st Century arrived,
Dr. Egon Wanke began development of a private, low cost, experimental Lightning Detection System,
and by 2009 some of the first systems began appearing.
[Image: green2009.jpg]
However "Blistered Tongue' was apparently mis-translated into German,
(or perhaps because of the updated Frog Firmware and Controller design)
the system is now called "Blitzortung"...

...In recognition of Tesla Drake's pioneering work,
and the contributions of numerous frogs,
the first Blitzortung system was called "System Green".

And there you have it.

Pretty clever!

"Dr." Egon reminds me, I think several of the developers have doctorates or other higher education.
