Re: [TenTec] Induction Field [WAS - PS grounding] (score: 1): Author: David McClafferty <ve1adh@yahoo.ca>; Date: Thu, 11 Dec 2003 19:29:53 -0500 (EST); "The magnets in use today in MRI are in the 0.5-tesla to 2.0-tesla range, or 5,000 to 20,000 gauss." And it doesn't change at all, some MRI's even use permanent magnets. Above is from: http://www.ho; /archives//html/TenTec/2003-12/msg00416.html (8,108 bytes)

Did some more reading and found there is a smaller magnetic field that is pulsed. I was wondering what the RF freq; /archives//html/TenTec/2003-12/msg00432.html (10,720 bytes)

The transistors are less efficient on some frequencies.

You would need "mu metal" for a magnetic shield. The "clamshell" type cases that Tentec used often act as a shorted turn; /archives//html/TenTec/2003-12/msg00730.html (9,809 bytes)

Re: [TenTec] Roofing filters (score: 1): Author: David McClafferty <ve1adh@yahoo.ca>; Date: Thu, 25 Dec 2003 10:09:03 -0500 (EST); I think of low pass roofing filters as shed roofs, where the rain runs all off one side and bandpass roofing filters as peaked roofs where the rain runs off both sides.
