It is often the monitor that causes interference.  It has a switching =
power supply
and a high power line sweep. Harmonics from these can cause bad LF QRM
which goes straight through the "radio transparent" plastic enclosure...
I got rid of a huge interfering signal on the 136kHz band just by =
changing the
screen resolution from 1024x768 to 1152x864 pixels. The change in line =
sweep
frequency moved the interfering harmonic way out of the band. Just a =
thought,
your mileage may vary...
