[Elecraft] Microham Microkeyer II, RFI in mike with my K3

[john at kk9a.com]

I own several DigiKeyer II's and a Micro2R and I have never noticed any
RFI issue. I have done nothing special in my installation to avoid RFI,
but I do eventually intend to bond all of my equipment per K9YC's site. I
have not used the Micro2R with an Elecraft on SSB yet (except into a dummy
load), but I have used it with other transceivers. I did use the Micro2R
for K3S headphone audio in last weekends RTTY contest.

Please confine your comments to areas where you are knowledgeable.  The
microHAM cables *DO* use a separate coaxial cable (or shielded twisted
pair) for each signal path.  The shields are connected to the shell of
the respective connector on each end of the cable.  With properly
designed transceivers, this design will minimize RFI issues.  When good
engineering practice is used in the station installation - including
antenna systems - there should be no RFI problems with a properly
implemented microKEYER II, MK2R+ or micro2R system.

Schematics for every microHAM cable are available from the support area
at www.microham.com or www.microHAM-USA.com/support.html.
