The original effort to try this was done by Dave Lang in CT USA. He was the first to move his antenna to that area for experiments. Mentions of this possibility was discussed with me by others over the last year. So with the invaluable help of Frank Kooiman the author of the LR program a new mode was added to the program to conduct experiments. The link below in red, on page 104 gives the reason and hope of improvement of this mode. In short, a 2dB per 1000 km improvement in signals from a lightning strike in the 3-6 kHz area. These were measured results, not theory ones it seems. This is early in the experiments but results so far are encouraging to say the least. More stations are needed to allow better results when connected to another 5 kHz station.
