RFI PC Speaker Hum

[Edward R Cole]

Just comment on radio speakers.  I bought the West Mountain speakers
for my wife's desk-top computer to cure RFI from my HF.  Works well.
Note the triband yagi and 80/40m dipoles are hung from a 50-foot
tower directly overhead of her sewing-room/office.

Interestingly, my Harmon/Kardon computer speakers seem immune to RFI
sitting right on the radio desk.  My radio room is next to her office?

For my ham rigs (K3 and FT-847) I am using an old 1950's era National
Radio speaker (10-inch diameter in the 11x11 inch metal speaker
cabinet).  Both radios internal speakers give too harsh a sound for
my ears.  I use a Sony MDR-V600 stereo headset and audio from the
radios sounds fine with it.

Hi Brian,

It's a more costly solution, but I ... and others ... swear
by the COMspkr(s) from West Mountain Radio.  They
work well, and even sound pretty good when listening
internet radio stations.
