The Lack of World Wide Communication for Liberians




As far as things look there are two Short Wave Broadcast stations in Liberia. Radio Veretas and Star radio. These stations broadcast in the Short Wave Band 1 of the short wave band which has the range of 3-10 Mhz.
In this band of frequency, broadcast is just a few hundred miles in the daytime and goes up to a thousand mile the night. World wide communication cannot be realizes since the earth is over 20,000 miles. These stations shut down during periods of maximum sunspot activities like in the afternoon. This is because the signals are absorbed by the D and E layers of the ionosphere. They resume broadcast in the evening when the sunspot activities are at minimium levels and when the D and E layers are virtually cleared out.


There are thousands of Liberian in other Countries of the world who would love to here live news form home. This opportunity is not afforded to them when Short Wave Broadcast in Liberia is still in the 3-10 Mhz band.


Recommedations

The 10-20 Mhz band of the short wave band is an excellent band for long range and world wide communication. Broadcast in this band is not hindered by the D and E layer in the daytime and are reflected by the F layer in the night. Once the angle of radiation is perfectly configured world wide communication can be acheived.
