Did Rife use radio or audio frequencies for his work?

HI
Is there Anyone who can solve the problem : for example the 1950 machine used carrier frequency around 3 MHz --how can anyone modulate this carrier with : example 400KHz,

Hi Peter,
Let me try
I'm using 3.0 Mhz carrier with Ralph Hartweel's SSQ-2F /last integrated processor-SP4/ This device is capable of being modulated with any frequency
up to 400 Khz in "TTL" mode.
Because I'm using also Hulda Klark's frequencies with Philp Hoyland's math and I give you my solution:
400 000 Hz x 7 = 2 800 000 Hz
400 000 Hz x 8 = 3 200 000 Hz
They both have 200 000 Hz /200 Khz/ difference from 3 000 000 Hz /3.0 Mhz carrier/ so now you can use it as a modulation frequency or go down, divide it by 2 to 10 or more to get lower subharmonics, and every time you will get resonance at 400 Khz.
This is my way.
Best regards !
