RF Seismograph – Can hams really detect earthquakes before they happen?
For many years hams have said when working the HF bands that there is a strange phenomenon which oftentimes occurs prior to an earthquake… the bands go silent and fill up with noise. What’s even more interesting is that the sun is quiet, therefore there is no chance that this is due to solar activity or any sort of solar storm. Alex Schwarz, VE7DXW, a ham in Canada decided to explore this phenomenon by creating an RF Seismograph. It’s simply…
