[TenTec] Re: EMI (was Argonaut 505 - The Answer)

[JAMES T HANLON]

Alan,

For now I will take the easy way out and keep the transceiver away from AC fields.  I'll bring a piece of steel down from the attic next time I'm up there and lay it on top of the transceiver between it and the power supply to see if that makes any difference.  Perhaps a steel bottom plate on the power supply might be helpful too.  At least I know what to avoid now.

73,

Jim

  Electromagnetic Interference:
  Without belaboring the point it was noted that the interference in the case of the 505 was magnetic related and not RFI. I did some GOOGLE searching on the topic (shielding magnetic interference) and discovered it is rather involved in shielding the problem and that removing (separating) the source is cheaper and simpler way to go. If you have the inclination you may want to check out the various sites for yourself with your own search. Very informative. Thanks Jim for pointing that out.

  Merry Xmas to all
