... The additional visual features of the WiNRADiO showed the dynamics of the activity on each channel along with the relative signal strengths, plus the ability to simply click and drag the cursor to any frequency on the display for instant access to transmissions ("Visi-tune"). These are distinct advantages when time is an important consideration while looking at brief transmissions.
... WiNRADiO also has a clever "waterfall display" function, downloadable from their web site, which provides a 3D look at a chosen spectrum and displays active frequencies over time.
... The WiNRADiO has highly flexible database management; load your most desirable search ranges into memory, then call them up when you are ready to do a spectrum search.
... For spectrum profiling, as the scenes continued to change during the course of the trip, nothing could outperform the spectrum display function of the [WiNRADiO] 3150.
