The software will find a subharmonic of the higher frequencies that will work in the Scalar range of < 50 KHz.
Q: Can I put the silver coin on the coil to help the frequencies higher?
A: That will not help. You can alter the upper-frequency limit on Out 1 to something higher than 50 kHz, but maybe keep the frequency at less than 1 MHz, maybe even less than 200 Khz.
