Radio Frequencies

After a pole shift radio could be the only method of communication. Knowing what frequencies to use becomes vital. If one listens or calls on a frequency that other are not using then no contact will result. It becomes desirable to predict what frequencies to use after a PS. The frequencies in most use today could be the best to use after a Pole Shift. So the question becomes what are the emergency and most commonly used calling frequencies today? This report details the primary frequencies on all bands that could be usefully after a Pole Shift.

Some of these frequencies will be more valuable before a Pole Shift and would be dead after a Pole Shift. Some you might listen to but not want to transmit on. The lower the frequency the longer the distance it can be herd. Use whatever frequencies your radio equipment is capable of. A low cost, low-power radio-scanner can be programmed with these frequencies to do the monitoring. It also may be prudent to scan other frequencies once on knows what the locals are using. Program a scanner, test, and get familiar with your equipment before the Pole Shift. Before the Pole Shift once the call is established, a good operating practice is to move off keeping the calling channel clear. After the Pole Shift with very scarce contacts one my wish to stay on the calling frequency so that others have the possibility of hearing and joining in. One other suggestion for an emergency frequency is to have the person monitoring key the mic and say so every 10 minutes - "This is station XXX listening".
