About Cumiana Observatory

The Cumiana VLF/ELF monitoring station is a remarkable example of citizen science done right. Run by Renato Romero (callsign IK1QFK) from his home observatory near Turin in the Piedmont region, it has been producing some of the cleanest Schumann Resonance data in Europe for over two decades. Its rural location, away from industrial electromagnetic noise, gives it a naturally low noise floor.

Cumiana captures a particularly clear view of the 7.83 Hz fundamental resonance. Renato's receiver design and antenna placement have been refined over years, and the resulting spectrograms show well-defined harmonic bands with minimal interference — making this data especially valuable for detecting subtle shifts that might be masked by noise at other stations.

As one of the few independent, non-institutional monitoring stations contributing to global Schumann Resonance research, Cumiana represents what dedicated amateur radio operators can contribute to geophysics. The station's data is publicly available and referenced in VLF research communities worldwide. Visit vlf.it
