I found this way of tuning my coils for maximum output. I tuned the pulse rate and pulse width for max. scope voltage. It was adjusted at the diameter of the coil. Just a interesting way of looking at the coil output. Best to all Jim

What
does that post have to do with my pictures? Sorry if they offend you, I thought someone might be interested in the results of some simple test. JimComment

KT, demanding that everyone post perfect pics is like demanding they write in perfect English. It's just not necessary.Comment

if i write bad in english you can correct me in any place. i will be only glad. but i ask to do digestible pics.
that is easely than to write in perfect English for me.

Thank you Carl, now it becomes clear how some people think so highly fo them selves. The interesting part of the test was the Hammerhead board put the maximum output to the basket weave coil, I di the same test with the PI-1 and Surf, PI-1. The test was just for fun, knowing that the voltage on the coil ramps up in a linear fashion and the current is 90 degrees lagging. . Best to all JimComment

Pictures are ok but NO IDEA what Tuning method you are trying to show us. Can you please explain the procedure?Originally posted by James View PostComment

Hi Waltr, I trying to see if the coil output amplitude voltage would increase by tuning the PRF and Pulse width to a search coil. The test is like tuning a HF transmitter for max. output with a field strength meter. I found that the basket weave coils produced more amplitude. The concentric coil were all less amplitude, I tried the Surf PI-1 and PI-1 boards they didn't produce the output the Hammerhead board did. All my coils are wound with Litz wire, 175/46 and 446/46 wire gauge. Just a raining day project. Best to all JimComment
