Re: VLF/LF converter?
- Yo Jim, Use an electret mic for an antenna - maybe you'll get a
way-cool "SDBD" (Software Defined Bat Detector). But you may have to
reduce the sound card sample rate though.
Anyway... Why not just receive VLF directly with a Softrock receiver?
Clock the softrock with a multivibrator and swap the passive HF input
filter with a low-noise op-amp VLF active filter.
