[QUOTE="Ronk, post: 105790, member: 3914"] well the only thing i am basically settled on is PI , and it seems to me i would need to vary the frequency or at least have it switchable to about 3 different frequencies , I can do all this the old fashioned way but i guess now you can do it with computers too . I have had a little experience on arduino and nothing at all on pic When i first learn about electronics it was all valves lol the next problem i can see is figuring out how to negate ground effect , I dont know if this can be done with computers , and lastly gain vs noise it seems when we try to get really high gain we get lots of noise so it would need some research into that . the trend these days seems to be going digital so only process signals that are on or off but i think we would need some analog preamps before we go digital any way just putting my thoughts down on paper ps i work in electronics on a daily basis and i can make pcb so if you have design you need to get a pcb for i could help pps i am hireing a sdc2300 in a couple of weeks, love the vids on youtube about them, makes my old sd2100 look like junk (looking for possible mods for the 2100) Ron [/QUOTE]
