Dear VLF enthusiasts,   browsing through saved VLF-grabber screenshots, I noticed some recent changes of VLF MSK-band usage:   2010-06-24 06:00  20.27 kHz (ICV) QRT 2010-06-30 05:00  16.4 kHz (JXN) Q

That's it, Rik! What about the model if we replace the switch by the loss resistance (today measured as 800 Ohm) plus a capacitance that is equivalent to the C between the electrodes? This could be d

Roger, There are many more regulations these days regarding RF exposure, and even the military must pay attention to them, especially when using civilian contractors. Necessary maintenance like tower
