InfraSonic Technical Topics

Here you will find information on equipment, techniques, hardware and software related to InfraSonic Experimentation.

My main interest is in DSP techniques especially ultra-narrowband modes. InfraSonic allows the use of these narrowband modes because of the easier frequency accuracy/stability requirements.
