Just reminded this paper from 2016 in JCMNS, after latest article in ECW.
Electromagnetic Emission in the kHz to GHz Range Associated with Heat Production During Electrochemical Loading of Deuterium into Palladium: A Summary and Analysis of Results Obtained by Different Research Groups
Felix Scholkmann ; David Nagel ; Louis F Dechiaro
There is a small literature on the combination of low energy nuclear reactions (LENR) experiments and radiofrequencies (RF). The papers are worth attention in case they can teach anything about the mechanisms behind LENR. Application of RF to LENR electrochemical cells in the mid-1990s clearly showed increases in the production of excess power. More recently, RF have been measured in LENR cells. However, it is still possible that those data are artifacts of the operation of the system, and not indicative of LENR. It has been suggested that the appearance of RF in LENR experiments is the cause of LENR, and not merely a manifestation of such reactions. That possibility has significant implications. In the present paper, we summarize and analyze the results obtained by different research groups concerning the application and emission of RF in the kHz to GHz range associated with heat production during electrochemical loading of deuterium into palladium.
It cites a recent experiment by Vittorio Violante at ENEA that was discussed here
one of the Current science LENR special section article :
Observation of radio frequency emissions from
electrochemical loading experiments D. A. Kidwell, D. D. Dominguez, K. S. Grabowski and L. F. DeChiaro Jrhttp://www.currentscience.ac.in/Volumes/108/04/0578.pdf
Maybe it can give ideas to some experimenters.
