Electronics, QRP & Homebuilding Equipment

I just like amateur radio operation with low power (5 W or less: "QRP") - even after more than 30 years in the hobby I am still amazed how far such tiny signals can travel. The following links are not exclusively related to QRP operaton, but I found them interesting, helpful, or both, and thus I would like to share them with you.
