Hi,<br>
<br>
With a high probability, you are receiving QRM from a switching
power supply. It can be the monitor's one, a plasma TV, the
Internet router, an electronic ballast from a lamp ...<br>
<br>
Begin switching off one at a time and you'll find the culprit. In
some cases it could be in a neighbor premises.<br>

HPSDR PowerSDR show spikes approximately every 60khz <br>
<pre>on my monitor.
This occur on all bands with antenna connected. If the antenna is
disconnected the spikes are gone.
Anyone have any idea what could cause this?
