Hi,
yes... but you provide data for coil... but not the other stuff...
Don't understand why you post coil data and then nothing else... so the thing you posted is just an oscillator !?
So... why ?
Ok, your choice... but that's not easy belive it can be used with success in real, working LRL... it's really low power... and not "state of the art" about stability.
I think people will belive in LRLs if a REAL and COMPLETE schematic will be posted... and anyone could replicate and check if works or not.
Don't need 30 meters or 5 meters range... also 50cm for a coin could be enough to show people if device works or not... but that needs you post something complete... not pieces.
Kind regards,
Max
