Don's directional loop should significantly reduce my tracking time for most
common switching noise in the neighboring area. I currently use a National RF
loop + preamp with an SDR-IQ receiver strapped with Velcro to a notebook PC.
The SDR-IQ is powered from the PC's USB port.
It's very helpful to watch the signature of a switch-mode noise pattern to
ensure you're not tracking other noise sources when roving on foot. It's
important to stay focused on one noise source before embarking on another. For
this reason, I recommend using an SDR receiver of some type rather than a
conventional portable receiver.
Next, my plan is to acquire an Expert Electronics ColibriNano SDR dongle
together with a Microsoft Surface tablet PC. That will reduce some of the
baggage and weight while roaming.
