I don't know anything specific about the MK2R, but many (most?) ham and computer audio products are built with very WRONG grounding practices. Indeed, most ham transceivers, including the K3, do some or all of this stuff wrong! There's a lot of VERY wrong thinking about hum, buzz, and ground loops, and that has led many folks to some really dumb practices that often CAUSE problems rather than solving them (and that are often a lot more expensive than solving the real problem). To understand what's REALLY going on with so-called "ground loops" (and some VERY low cost solutions), have a look at http://audiosystemsgroup.com/RFI-Ham.pdf and http://audiosystemsgroup.com/HamInterfacing.pdf 73, Jim Brown K9YC _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
