This would be a great application for JT65A, which could allow many NA
stations to work him.
The traditional way to call someone on JT65A is to zero-beat them on the
waterfall. The better way to call a DX station is to NOT zero beat
them, but rather to spread out like a split pileup. Since the window is
about 2.7 kHz wide, a JT65 signal is about 220 Hz wide, and signals can
be decoded with some overlap, at least a dozen signals can
simultaneously call and be decoded. JT65A activity on 160M is from
about 1838.5 - 1841.2, transmitting by feeding a USB transmitter with a
carrier of 1838 kHz.
The software of choice is JT65-HF. It is freeware, well documented in a
pdf, and very easy to use. A QSO typically takes 5-6 minutes to complete.
