Colin would like some information about where, and when, it can be heard or otherwise detected. It appears to be being driven by the French. Forthe record I can hear it here in Shetland. It faded up tonight at approx 1615 UTC and is audible and visible on a waterfall display. I haven't been in a position to DF it, but in the first instance Colin would like to gather some information about where it is being received. I can collate the information for him if anyone who is affected by, or can simply detect, this noise/data signal could give details either direct, or via the LF group. I know a lot of discussion has been had already, but a quick note now could be useful, as there is a meeting soon to discuss this, and other aspects of WRC2012. Cheers, John GM4SLV
