My first 2X 73kHz DX contact was with G4JNT on 23/8/97 using CW, over a distance of 57km. No one down here came specifically from top band and I had not operated on that band since 1959. On a different subject does anyone know of the correct designations for Litz wire. The wire that came from the Decca coils is 3mm diameter (4mm with insulation) and has around 850 separate .2mm conductors. (the wire count is an estimation). Some other wire I have from the Crawley club is 1.5mm diameter (2.7 mm with insulation) and has approximately 200 .2mm wires. I am sure I have seen designations for Litz but I can't remember where.
