Pocket-Size VLF Up-Converter: Extremely Low-Cost, Great-Performance

In this video we’re building a compact VLF up-converter, transforming elusive VLF signals into a manageable shortwave frequency ( 10MHz ) for portable reception. This project emphasizes leveraging common, affordable components to unlock the mysteries of natural radio and preparing for the Christmas SAQ transmission, proving that VLF exploration doesn't require expensive, specialized equipment but rather clever, hands-on circuit design.

ORDER THE PCB BOARD OR ASSEMBLED VERSION:
Due to the fact that the NE612, NE602, SA602 or SA612 chips are no longer in stock from major suppliers, the assembled version from PCBWay will be delivered with ought the IC and you will install that one on your own ( not provided by PCB Way ). Instead PCBWay will only install the IC socket so you don't have to do any soldering.

NOTE:
I’m not an engineer, but I build equipment for fun as way to relax, while enjoying the amateur radio hobby. All videos and projects are built with the limited knowledge I had at the time I recorded each video. Some projects may be updated in time and I publish new videos. Always check for the latest versions ( read the blog articles ).
