Random signals on the
amateur bands that talk among us...
The Hall of IMD Infamy
A very special baker's dozen collection called "The
Dirty Dozen"
A spectacular S-9 + 40dB signal that stretches out to 22 kHz
in width! It sounded as bad as it looks here!

This beauty is roughly 20 kHz wide!
Those ripples above the transmitted signal extend the
total bandwidth of this signal out to more than 15 kHz total!
This winner is roughly 20 kHz wide.
Yes...this is one signal!!!! It goes on and on and on in
both directions!
This mess is extending out beyond the band edge and
rippling through the RTTY station at 4.005 MHz.
This signal gives new meaning to "reaching out to touch
someone"as it clobbers a station operating 7 kHz up the band.
Yes, this amazing devil-horned shape is one signal...
This curiousity is roughly 10 kHz wide so compared to
many of the others he's looking pretty good!
Another 10 kHz wide splatter mode transmission.
Distortion products are appearing about 15db below the
energy at F-0.
This signal sounded as bad as it looks.
This attempt at a 3.8kHz ESSB signal is a major fail as
the distortion made it nearly unintelligible.
Wouldn't it be nice if everyone kept it clean?
