I want to change the frequency multiplier to 2 in the Holland 11 for my biofeedback scan preset. This will raise all of the frequencies by 2 and then the preset will add the multiplier for the out 2 by 11. Thus bringing me closer to my treatments being in the 1+mhz range?
Yes and no. Doubling the frequency hits from the default scan range of 76 kHz - 152 kHz will raise them to the next octal range of 152 kHz - 304 kHz. The 1 MHz range is still 4 octaves away.
If you were to multiply the hits by 16, this would put your hits in the 1.216 MHz - 2.432 MHz range. The 11th harmonic would just be 11 times whatever range you decide to work with.
However, being that the 11th is just another frequency unless paired with a fundamental, I personally would not focus on the 11th to be in the 1 MHz range if my goal was to target the pathogens using frequencies in the 1 MHz range.
If having the 11th in this range was your goal, then using a frequency multiplier of 2 the 11th harmonic would fall between 1.672 MHZ and 3.344 MHz.
Edit: If you decide to use a multiplier of 16 to hit the 1 MHz range for the fundamental, the 11th would still be well within the generator's capabilities. In order for this to work, you will want to use the Add F1 to F2 method for the 11th vs using Out 2 x 11. Otherwise, you will need to pair the use of a WCM of at least 5 (recommend 6) so that Out 2 does not get re-modified to a frequency below 5 MHz rendering it no longer the 11th harmonic.
If you wanted to use other sets, you may wish to investigate how to set frequency limits. Since the biofeedback session is a predicable single octave range (meaning the end frequency is double the start), I can use a frequency multiplier of 16 to get it into the target range you wanted. With other frequencies, a multiplier of 16 won't work for them all.
Read the following to gain a better understanding of the effect of frequency limits: https://www.spooky2-mall.com/blog/harmonics-explained/
However, as a quick example, you would set the limiters to say < 1000000 and > 2000000 to ensure all frequencies are in between this range using the harmonic type selected.
As for a carrier wave, this is one that others may have different opinions on. From my perspective, a carrier is a larger frequency that another frequency is modulated into. The generator can do this only by use of the Modulate F2 using F1 options. Otherwise, it just frequency addition, which is not much different that say listening to two flutes make two distinct notes. The higher frequency that you may consider to be a carrier wave isn't really carrying anything.
With that said, carrier waves are applicable to contact and plasma methods of application, but are pretty much not necessary for remote application. The value in a true modulated carrier wave via remote application is in the side band frequencies generated.
I would not worry so much about trying to ensure that all sessions are between 1 and say 2 MHz, or if you are using a carrier wave to drive it. I would suggest that you start with a baseline (like the suggested settings) and then once you have your own data to work from, you can try alternatives to compare.
Finally to clarify on the use of 16, I got this by looking at the range of the biofeedback scan and realized that to get the returned hits into the 1 MHz+ range I had to raise them by 4 octaves. This is 2 * 2 * 2 * 2 = 16
The article I linked will help you with what an octal range is if it is still not clear.
