It is interesting. Since I only really listen for a few minutes at weekends (leaving automated monitoring to capture screenshots, WSPR records etc.) I am not sure how frequent it is. I wonder what equipment would be used to facilitate out-of-band (presumably illegal) HF transmission such as this? Ed
