Before going too far down the trail about lacking detail, it's important
to realize that resolution is also limited by the FFT parameters used
to process the complex IF signal and convert it to the frequency
display. According to N1AL, here are 468 active FFT bins. I haven't
seen numbers for the frequency and time resolution of the FFT process,
but the upper limit of frequency resolution is (F2-F1)/468.
FWIW, I'm quite happy with the P3 display, and only wish it were smaller
(that is, less depth front to rear) with a swiveling bracket to mount it
to the underside of a shelf above my rig.
