Hi VLF,Here i spent some time to modify the VLF PA used during the field experiments. The old version was on a wooden plate (known from the photos in a few amateur radio magazines and images at qrz.com). Now it even has an EMI filter!! :-) and a switch and fuses and a grounded box which is better due to safety aspects (other people could touch it when the plug is in and i'm not watching). Maybe i can replace the fiber optic cable by a simple optocoupler and isolated BNC jack. So far for today: https://dl.dropboxusercontent.com/u/19882028/VLF/20131219_221825.jpg 73, Stefan/DK7FC |
