Re: [perseus_SDR] Laptop Induced Noise
- Have you tried wrapping the input and output cables from the laptop power supply with toroid chokes? I've had good success quieting PC noise that way for many years.

And just to complicate matters further ... I use an HP Pavilion g series
laptop. It is whisper quiet at my primary QTH, where my Wellbrook loop
is mounted 35 feet from the house and everything in the shack is
grounded. At my condo in Chicago, however, the same laptop is noisy,
although I am using a third-party power supply and the Wellbrook loop is
installed only 8-feet away from the building. Fortunately, the noise
disappears when I run the laptop on batteries, so that is how I use the
Perseus when I DX from downtown Chicago.
