UK radio amateur Chris Wilson 2E0ILY made what may be the first 136 kHz (2200m) transatlantic contact with a radio ham in the USA operating under FCC Part 97

Chris Wilson 2E0ILY in Shropshire worked Paul Kelley N1BUG in Maine using the mode DFCW60 which is dual-frequency CW with a 60 second dit length.

This was not a quick contact. It took four nights to complete, using night-by-night sequencing. The two-way exchange included call signs, signal reports, and acknowledgments. They used the TMOR reporting system, borrowed from the moonbounce world.

The contact was finally completed at 0020 GMT on March 28, 2018.
