The Wilderness Protocol is simply a recommendation that those outside of repeater range monitor standard simplex channels at specific times in case others have priority or emergency calls.
"FM & Repeaters", June 1996 QST, p. 85.
Simplex frequencies: 146.52 <-- primary 446.0 223.5 52.525 1294.5 Monitor at least 07:00 - 07:05 10:00 - 10:05 13:00 - 13:05 16:00 - 16:05 etc.; if possible, monitor every hour. Priority/Emergency transmission: begin with 10 seconds of DTMF "0" (this is called LiTZ, "Long Tone Zero", and is a good idea for repeaters as well). Routine transmission: wait until four minutes after the hour.
