Keep up the good work -- it is inspiring and appreciated. So far, my best VLF DX is 4.7 km with QRSS and 2 km on CW and 1 km with a portable home brew CW RX and PA0RDT miniwhip. 73 Joe VO1NA On Mon, 20 Apr 2015, Roger Lapthorn wrote: > As many of you will recall I had a cerebellum brain bleed in September > 2013.
