Any hits that are from targets that respond better to a frequency outside the scan range, are hit by octal harmonics.
Any frequency doubled, or a power of 2, shared common properties. They for one, share common nodal points (the area where a frequency crosses 0).
This is like all C notes on a piano, each are double or 1/2 of the previous note. Since 76000 resonates every other nodal point of 152000, something at 152000 will still be targeted by 76000, only it will take more energy to produce similar results.
While some hits may be a result of a frequency outside of the scan range, and would respond better if you used that specific frequency, the fact that it registered as a top 20 out of 3800 frequencies means the resonance was still significant and use of the scanned frequency will still produce good results.
After scanning and applying the default range of 76k to 152k for some time, you may wish to try other octal ranges. For instance, you could scan 800 kHz to 1.6 MHz, using a step size of 200 to try your hand at this range.
If you are using a sine wave to scan, your hits are for the frequency scanned, and only the frequency scanned. You are then free to use any waveform you wish to apply, which will induce other harmonics. You are at least still producing the fundamental frequency your scan indicated did actual work.
If you use a different waveform to scan, you will want to use the same waveform to apply the results, as then you have no idea if the hit was for the frequency scanned, or from a harmonic from the waveform used to scan. Use of another waveform thus may not produce the same frequency that resulted in the hit, and end up wasting your time.
