Shielding, another topic in the series...

[lamoiz]

after measuring the capacitance between the turns and the shielding, I am at 260pf. so if I reason well, that I take into consideration a value of 14.38mh, in parallel with its capacity of 32.2nf, the frequency is 7.28 khz, now, if I calculate the srf, I am at 82.64khz. so sufficiently far away. am I right?

Is this for a TX coil or a resonated RX coil?

This is the RX coil

I like to keep the SRF at least 10x higher than operating frequency, so this should be OK.
