hello
@ Groungloop

This is my first post although i have always followed the development in this forum.
I will like to ask, did you at any time measure the frequency of oscillation of your circuit? i will appreciate if you can give the frequency of air core design and the ferrite core design.
I thinking the higher the frequency the better the charger abilty to desulphate. Correct me if i am wrong.

@tonyben25,

I do not have the air core version anymore, but I did measure the Ferrite version today.
The oscillator fundamental frequency is in the high audio range but since the pulses
are "spiky" then there is a lot of RF spectrum up to approx. 5MHz. Attached is a spectrum
plot from 0 to 5Mhz. Sorry for the time it took to answer you question. I never did see this
post until today.

GL.

tonyben and Groundloop,
I built mine a few years back with an air core, and was able to get the frequency up to about 20MHz using a potentiometer in place of a resistor. It's been awhile, but I think it was either a 5K or 10K pot. I also swapped out one of the caps - tried a few different ones to get the highest frequency possible.
