Band

Comments

000 - 150 kHz

VLF band. Signals on these frequencies cannot propagate well via the ionosphere, but are able to penetrate ocean water well. As a result, several military stations used for submarine communications are found here. Most transmissions are in CW and RTTY. You need a really large antenna - hear much here, and in most locations electrical noise and static will be too high.

135.7 - 137.8 kHz

This band is assigned primarily to fixed services and maritime mobile
Secundary fixed amateur service with a 1W PEP max.
In Region1 amateur assignation is next:
135.7-136.0 : station tests & transatlantic reception windows
