May Meeting:
Computer to Radio Interfacing Without
Pain -- presented by Jim K9YC
2nd Wednesday, May 14, 2008
Most hams (including authors of some ARRL publications)
believe that transformers, expensive boxes, or even optical isolators are
needed to connect computers and other gear to transceivers without hum
and buzz. This is sadly (and expensively) wrong, and so are many of the
solutions offered. An unshielded transformer or an improper shield
connection may CAUSE hum, buzz, and RFI!
This presentation shows simple and effective solutions, involving no
more than a few feet of copper braid and properly wired cables that can
connect anything to anything, without transformers, interface boxes, or
optical isolators. Audio connections are addressed first, followed by rig
control, sending CW, PTT, and RTTY.
