Sub 9kHz amateur radio

Although far from perfect, I try to keep up with the latest news about amateur radio below 9kHz. Quite a lot is happening.

Surprisingly, large antennas are not needed for receive and all the software you need is free.

This is one of the true frontiers in our hobby and access is easier and far less expensive than you might think. A perfectly fine RX setup can be made for a few cups of coffee in a café.

Most activity is just below 8.3kHz, which remains unallocated in many countries.
