Default Re: Regarding home made TRF

The commercially available coils I am aware of mean I would have to redesign the circuit of the detector.
Presently I have re-wound the coil for the electron-coupled detector with but one 65 turn winding for the detector. Aerial coupling is two turns of wire as a loose coupler arranged around the coil form. The presence of the 100 turn winding still exerted a loading effect even as it was completely disconnected.
The detector works much better now.
