QRP Frequencies

Center of Activity

These are not Calling Frequencies, they are Centers Of Activity - places where QRPers are likely to be found.

Of course, you may operate QRP anywhere that your license allows. If you have a VFO, then use it - but check around the QRP Frequencies on a regular basis.
