Does this mean a topic like "What Makes 160m Tick" would not be welcome? Couldn't resist. Carl K9LA _________________ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

For a given electron density profile, the amount of refraction incurred by an electromagnetic wave is inversely proportional to the square of the frequency. The result of that is the lower the frequ

For those who are antenna challenged, don't sell a 160m inverted-vee at low height too short. My 160m antenna at the moment is an inverted-vee at an apex of 45 feet. Additionally, the last third of e

Nick VE7DXR, At least they corrected the vertical axis of the 10.7 cm solar flux plot - it used to say sunspot number. What I do for the Ap is download the data from "Table of Recent Solar Indices (P
