SWL & Ham Antenna Options For Tight Spaces
Shortwave radios typically have a tele-scoping whip antenna to do the job. With that, be second only to the historic solar cycle maxi-mum of 1958. Veteran radio hobbyists remember that cycle, when solar activity was so strong that ... Return Document

Radio Wave Propagation - IOSR Journals
Radio Propagation has a strong connection to space weather. A sudden ionospheric disturbance or shortwave fadeout is observed when the X-ray associated with a solar flare ionize the ionospheric d-region. Enhanced ionization in that region increases the absorption of radio signals passing through it. During the ... View Full Source

Shortwave fadeout (SWF) is one of the well-known radio wave anomalies that occur in the upper atmosphere. During a solar flare, the sun emits soft and hard X-rays in the order of ≤1 nm, which penetrate through the ionosphere and reach the D-layer, resulted in a sudden increase in plasma density. ...

Optimum Frequencies For Outer Space Communication
Within the solar system there is evidence of ap­ preciable densities of electrons out to great distances from the sun. Transmission time delay will become substantial in outer space communications, e.g., 2.6 sec are required for a round trip radio signal to the moon. This time delay is essentially independent of operat­ ing frequency. ... Access Doc
