Radio Roundhouse

It's a quiet week in Coastal MS, but here are a few things that have surfaced in the amateur radio world:

• The Mississippi QSO Party this Saturday from 9am – 9pm local.  announcement  
• DoD to Transmit Interoperability Exercise Info via WWV.  These are always interesting.
• Kevlar-reinforced antenna wire.  Incredibly simple, insanely great, and yet blindingly obvious now that someone has invented it.  Why did it take so long?  I don't really need any right now, but I have the feeling I'll be getting some soon anyway.  No wait, just thought of something I need it for.
• And finally, see figure below explaining why AC current can pass through a capacitor, but DC current is blocked.  Found at KB6NU's site.

This is even worse than the worst bad pun.
