No you missed understood. The only reason i changed the frequency is so that the AM radio could tune to that frequency. So my AM Radio would recieve the signal like a radio station. So with this I could measure exactly how far the signal goes. Regarding the speakers the rating didnt make big diffirence as long as its a north pole speaker. I do not use a frequency generator, i just modified the original zappicator cercuit. ( which i build myself ) i have all the cercuits and vidios. I will gladly work step for step with you. It is really cheap to build. And I found building the machine yourself is 80% of the healing ( in my opinion ) Hilda Clark had all her students or patients build a syncrometer and a zapper, that was part of the treatment. Bob beck also gave all his patents, we should just grab and use it.
