FWIW, be careful with your measurement process. I got very depressed when I saw that my K3S had harmonics only 20db down on most bands when measured by Tiny SA and its telescoping antenna. It was not being overloaded and in fact I measured similar results when feeding a dummy load. Then I went outside the shack at a distance from the antennas and found that the harmonics were 40dB down or better. Evidently when measuring inside the shack I was getting RF leakage directly through the front panel of the rig. (?).

Someone did a compare of the tinySA to an HP, and it was within a few dB as long as it was overdriven. We are looking for splatter or harmonics, not doing a proof of performance. 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst.
