Putting up VHF and UHF antennas quickly just got a lot easier due to
the Connect Quick boom-to-mast system from Paul K1PJM at Ironworks
Design. He has invented a kind of "quick disconnect" for antennas
that looks like a real time-saver. His Web site
(http://www.connectquick.net) has illustrations and a video showing
how the product works. Ham ingenuity strikes again!
Mike WA8MCQ found a good online resource
(http://www.g3ynh.info/index.html) for technical articles about HF
power transmission. At the top of the page, click on "From
Transmitter to Antenna: HF power transmission theory and practice"
and you'll find an index page with a lot of articles. "Theory and
optimisation of current transformer bridges" is interesting, too.
Alex KR1ST just released (http://www.kr1st.com/freckles.htm) a
Sidebar Gadget for Windows Vista called Freckles. (Vista is required)
Freckles is a small application that will keep you informed of the
current Sunspot Number, Solar Flux, and Interplanetary A and K
indices. These values are continuously updated so you don't have to
go browse the net for the latest numbers or log onto a spotting
network to obtain the latest numbers. It also displays the latest
Extreme Ultraviolet Telescope image of the sun.
