Stefan, there must already be some saturation of the >material. When a ferrite core gets warm or hot this does not necessarily mean that it's saturating.It's the losses which heat the core. You can e
Stefan et al, Not being too familiar with LOPTs what inductance are the windings? Are there particular non-encapsulated types that would be more suitable for compact loading coils for lower powered 8
VLF, The LOPT still works, seems to be no problem. Just a FET was sk. Somehow all the previous problems are gone now and i am getting about 2 kV rms from the transformer. So i stopped my LF beacon on
Hi Roger, Well, they are not as suitable as i expected. Just a few kV can be generated and applied to the wire. But that's fine for local tests. I didn't measure the L but rather tried to find a reso
VLF, In the evening i got the idea to make a comparison of the signal level when using the LOPT and another reference signal. The levels were measured and compared in SpecLab. I used an E field probe
