UHF/VHF Simplex Wilderness Protocol




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.
