Waterfall appearance versus SNR
I'm feeding a new KiwiSDR with a wire dipole which is resonant at about 3.4 MHz (about 138 ft. total length), about 15 feet above ground, in a rural area of Michigan. At night I'm typically seeing SNR 34:30 values. Replacing the SMPS should improve things, since there is a visible noise pattern it adds, though less obvious at night. The SNR values being reported seem to be higher than many of the online KiwiSDRs that I have looked at....however I need some seasoned KiwiSDR owners/users to take a look at the attached spectrum/waterfall to assess whether SNR 34:30 is a "real" value, i.e. does it actually reflect an above average signal environment?
