Can Spooky2 Scalar biofeedback scan support high end frequencies from 14MHz to 16MHz?

No. The carrier is only about 5.6 MHz, so modulation cannot be too high. If the modulation gets too high, it becomes itself a carrier. So the characteristics of the system change. I found during experiments and tests that 50,000 Hz was a good maximum. This is why it is in the presets. Of course, people are welcome to use higher modulation frequencies. I would say that at the very most, 1.7 MHz should be the maximum. Beyond that, the power to the coils will be markedly reduced.
