In my previous video, I shared my M&P for building a replacement Antenna Coil for the MECK DA-601 TRF receiver using a Ferrite Toroid F50-61 after calculating the required inductance then winding the secondary w/ 28 AWG magnet wire and the primary w/ 26 AWG magnet wire.
Excel formula example for the secondary based on my TRF receiver:
=25330/((437-13)/(((1.7/0.535)^2)-1)*1.7^2)
A great resource:
