Aloha from Maui - the alaska rx is the inspire or was aspire vlf kit with 12ft whip and grounded into pole sunk into lake bed  (prob a tadge too long) cat5 about 300ft with isolation transformers at each end then straight into pc sound card - its not too bad but youll see wb qrm from power metering which modulates the 60hz and produces qrm to to 100khz or more - hate it

Its located on my frozen in dock by the mud hole ie lake

Im actually feeding power up the spare cat 5 pairs just at 5v at the moment as im borrowing stuff to set up rx and tx from here on 475

Cheers
Laurence (actually working not playing for the moment....)

Laurence, thanks for the VLF grabber. Wonder what you're using for the receiver and antenna?
