Write LOCATION to Cabrillo, and give CQ WW M/2 eight band changes an hour

CQ WW lists LOCATION as required, and the export never wrote it. It now
carries the ARRL section, state or province, or DX.

CQ WW M/2 has no stay on a band: it may make eight band changes in a clock
hour. It was getting the ten-minute stay that M/S has.
