I think that W1VD has detected my signal some years ago. But that was not JT9-1. There have been older versions of JT9, allowing to use longer time periods, up to 30 minutes i think! That was better for LF! I am not so sure about the detection by W1VD. Maybe Jay want's to comment... 73, Stefan Am 17.11.2017 15:29, schrieb Chris Wilson: > 17 November 2017 > > > Has there been a previous trans Atlantic reception of a JT-9 signal > from the UK? > > > >
