So on 80m, my favorite parts of the band are at the low end (CW and Digi modes around 3580 kHz) and the very top end with PHONE nets around 3990 kHz. Of course, hams do not operate on a single frequency, but QSY on a band. My 9th grade understanding of SWR and Smith Charts tells me that everyone can "see" the Bull's Eye on a target as the goal in darts, and in antenna matching, the goal is a perfect match to a 50-ohm feed line at some frequency. RETURN LOSS (as a positive number, in dB) was not a term I was familiar with before playing with this Nano VNA. The larger the radius (centered on 1.0 as 50 ohms) the higher the absolute value of reflection coefficient and the higher the SWR. I was hoping to get some feedback on is this portrayal of |reflection coefficient| or rho as the radius of a circle on a Smith Chart.
