New: King Cobra 15 Khz VLF Project for 2016 !!
________________________________________
I am just now putting the information together on this cool project, originally from another forum . I do not think the circuit boards are being sold anymore. I am looking for the final schematic and final pcb sprint lay-out file.
The nice pcb boards that were made in 2015 were called Marauder pictured below and below the original king cobra schematic from W. Lahr . I am looking for the large 15 khz DD search coil data also.
