Interesting Phenomenon with DD coil

[pechkata]

There are not any capacitors. I measure the instantaneous current through the coil.
See the diagram.

Detector #1 has never worked above a pulse.

OK, I'll stop.

Hi boilcoil,
Don't be influenced from side noise, please. I will made a second sample at TX-ON time and will add additional resistor in series with TX coil to achieve exponential shape of the TX current according your requirements.

pechkata, please don't add noise to this discussion!

The topic has died down (over-damping). Anything new?
