Colleagues, I know it's off topic, but what do you mix the epoxy resin with to make it not transparent? Thanks in advance.

Dear CEBRAIL, thank you for your help and I appreciate that, may you please give us more detail about the configuration ? My admiral works great (First version), but it have a problem of ground potentiometer, when I turn all direction the sound changed from low pitch to high pitch ??? I think it is not working the ground pot ??? Am I right ?

In your Tchaikovsky admiralin trials, first of all, tx own resonance brake coil inductance is well adjusted, ground opamp works very well, Q factor in the coil, then the rx resonance resonance brake between tx and rx is very important. The enameled wire thickness will be used in the coil. There are calculation programs when winding the bobbin, I prefer you to use it.

100n. I`ve seen in other projects less values of this capacitor but I am not sure what what would improve the performance of the chain. In the air there may be no noticeable differences. Possibly on real ground some difference can be found. Only a practical experiment can answer the question...
