The swishing (sweeping) noise peaks at 14.085 & 14.095, 14,185 & 14.196 on the 20 meter band. more than just those freqs but those are of interest to me. Similar situations all across the spectrum every 100 + kc. 7196 & 7202, 7297 and 7302, 3852, 3956 as examples. About S-7 on those freqs. Thanks Larry W0OGH
