WSPR propagation time/distance

Hi,

With ARQ modes such as AMTOR and PACTOR, it was possible to estimate the propagation distance via the RQ time delay. Would be nice to have a protocol built into WSPR that could negotiate a transaction between stations to give timing info. Perhaps a check box option that allows stations which can hear each other to pair off into this mode. TX/RX delays are an issue here, but at the very least relative timing variations over an epoch would be interesting, and TX/RX delays could be calibrated out for absolute values. I guess the JT modes will do this for back scatter, but would be interesting for WSPR as well. WSPR is a great idea.
