A note here. I bought a set of coils and electrodes from Meyl. I got the 3.5 Mhz coils. Yes, I was able to get higher voltage off the receiver coil than from the transmitter coil, but some of the other results were not as definite. Could be, probably is because I am not using the same signal generator. The one he sells is very expensive and I thought there should not be that much difference. But as it turns out, the cheap ebay DDS signal generators are not up for the task. His prices are just too high to spend any more. It cost me $120 just for shipping and still took just shy of one month to receive the parts. Don't get me wrong, I love what he is doing but just can't afford to get the right equipment.
