Well Harvey, the probable reason that you can't hear WWV on 10 MHz this morning is the MUF is just too low. At 1100 this morning the vertical incidence MUF was below 3 MHz. That is about where it has been running recently. The estimated MUF for a 1000 miles (1500 km) is about 8 MHz. That's why WWV isn't heard early in the morning. Kerry
