Alberto I2PHD, Alberto, first of all thanks for providing ARGO, I have played around with it and found it very useful. About the coils on 9 kHz: I am using a u-shaped core with a closing bar on top
Alberto I2PHD, As a matter of fact, at 137 kHz the inductance values aren't so big to make it impractical to wind them. At 9 kHz things are a bit different...< Alberto, first of all thanks for provid
Hi Alberto Stokes original article was re-printed in the old LF Experimenters Source Book, together with another explaining the theory. I built the original circuit. It is very simple and lacks most

Has anybody experience with gyrators ? A friend pointed me at this page : http://www.aavso.org/committees/solar/gyrator.stm which contains the schematic of a VLF receiver where the inductances have b
