The Wilderness protocol (see page 101, August 1995 QST) calls for wilderness hams to announce their presence on, and to monitor, the national
calling frequencies for five minutes beginning at the top of the hour, every three hours from 7 AM to 7 PM while in the back country. A ham in a
remote location may be able to relay emergency information through another wilderness ham who has better access to a repeater. Calling
Frequencies: 52.525, 146.52, 223.50, 446.00, 1294.50 MHz.
Some scaled down version of this may work after the Pole Shift. Say include HF Calling frequencies and call only during mid day.
