NEIL SPOKES' AMATEUR RADIO ACTIVITIES

G. NEIL SPOKES, AB4YK

In the picture above I was sitting at a Skyline Drive, VA, overlook participating in the annual 10 GHz contest August 2009. One possible goal is to get operational on 411 GHz one day. I have summarized some “above-300 GHz” material at the following web location:

I hold an Extra class license from the FCC. My amateur call letters are AB4YK. I am active in amateur radio, and I participate in the local Fauquier Amateur Radio Association’s club activities.

I am particularly interested in VHF propagation under Sporadic-E conditions. Sporadic-E is a mode of propagation via the ionosphere that like its name implies is sporadic in nature. Normally the E-layer of the ionosphere only permits fairly low frequency operation. But when sporadic-E conditions prevail VHF communications can be made by single hops of 700 - 1500 miles even though this part of the ionosphere is normally unable to sustain such high frequency communication. Through interpretation of data in the findings of amateur experimenters, I have hypotheisized that the sporadic-E mode of propagation owes its existence directly to clouds of micrometeoritic particles that are orbiting the sun, basically following the same paths as comets. The meteoritic hypothesis has not been successfully challenged. But neither has it been universally acclaimed.
