>- Back in 1970

My first was 1967. The Ham Radio operators club was on PBS. My dad and one uncle were radio operators. During the 1960's, I went to HamFests and swap meets at least a couple of times a year.

>- It is nice that you have 17 years experience.

Yes, that is with zappers. My first CPU experience was with a Heathkit back in 1977. My first experience with the 555 was in 1975 using a circuit almost identical to the Clark zapper but for different purposes.

Graduate studies in biomedical engineering in the late 1970's. Later worked with a company that manufactured cardiac monitoring equipment. Following that, I designed laboratory test equipment.

Sure, theoretically, skin effect is a consideration but skin resistance can be an offsetting factor with proper signal application.

>- that simple "zappers" can have limited beneficial effects, in limited circumstances.

Yes, and advanced products like ParaZapper have have far better effects and results. ParaZapper is genuinely effective in killing many microbes and has the ability to penetrate better than many other zappers.
