Hi group,
Has anyone else tried this with their LF/VLF receivers ?
I have put a microphone on my SLM and have been receiving bats. I used a
tiny electret condenser mic capsule on the input of the D2006, with the
usual 1.5V cell and blocking cap to power the capsule. I was able to pick up
bat sounds up to 55kHz. There were some clicks down at 22.5kHz, and some
twitters around 45kHz. I think they are just the common or garden
Pipistrelle bats.
The bats are attracted to our big halogen security lamp, because of the
insects that fly round it.
I haven't fed the signals into Argo yet ...
