I saw a few pictures online about the DIY bowtie antenna and I was curious. Could it be possible to construct an antenna that would pull in the digital channels on the cheap? I found some excellent information on how to build an HDTV bowtie antenna. Will the coat hanger antenna work at all? At first I […]
There are groups out there that want to save this, expose that, and rescue the human race out of destruction. It is often the most simple things that are overlooked and that are the most important.

In my quest of learning electronics, I try to understand radio propagation. All of the numbers, terminology, and charts can be somewhat overwhelming. Is there a simple, quick reference to better understand the HF progation numbers? 1. K-Index — 0-9. Overall, low is better. Some VHF operators like to see an increasing K Index, because aurora […]

The ten meter band (28000 to 29700 kHz) tends to be at its best near the spring or fall equinox. In fact, the equinoxes are when geomagnetic storms are the strongest. These strong geomagnetic storms can actually be very disruptive to the […]

The August 31, 2012 Full Moon is a Blue Moon, Maybe… “Once in a blue moon” is another colloquial expression used in America to mean “a rare event.” In reality, the moon isn’t depressed or shaded blue, it’s the second full moon in one month as we perceive it to be, and originally it was the third […]
Another conspiracy buff (intelligent person) says that he has been investigating even further, and you may be surprised about his investigation. He claims that the US State Department, headed by Secretary of State Hillary Clinton, is spending US taxpayer dollars to repair and rebuild mosques in the Middle East. Fact or fiction?
