VLF loop and up-converter ready for tests

This is a shot of my receiving loop antenna for sub-9kHz local earth-mode and induction comms testing. The loop consists of 30 turns of wire on a wooden frame. This feeds into my SBL1 based VLF-to-HF up-converter (the small blue box on the frame). The output of the converter feeds into the FT817 receiver.
