Net & Band Data

Where to find HF SkipNet traffic on the air, and the digital sub-bands it lives in.

Maintainer's Note

This page needs to be severely updated — most of it is outdated and obsolete. It's a work in progress. Treat the data below as a historical reference, and confirm current frequencies with the net managers listed on the Contact page before relying on it operationally.

Automatic Control — The Regulatory Basis

HF SkipNet stations operate unattended under the FCC's automatic-control provisions for digital traffic:

§97.3(a)(6) defines automatic control as the use of devices for control of a station when it is transmitting, so that compliance with FCC rules is achieved without the control operator being present at a control point.

§97.221(b) permits a station to be automatically controlled while transmitting an RTTY or data emission on the bands at 6 meters and shorter wavelength, and on the coordinated segments listed above.
