Broadcast History - October 23

Postby jon » Thu Oct 22, 2020 8:34 pm

Another quiet day in Western Canadian broadcasting history, so we look elsewhere in the world.

In 1999, Radio St. Helena broadcast to the world for what it thought would be the last time. Its powerful shortwave transmitter was showing its age and becoming impossible to find spare parts for. It was being replaced with a low power transmitter that could only be heard locally.

In fact, there have been special transmissions since then. There was one on December 15, 2007, which was a double anniversary for the station. It marked the 40th anniversary of Radio St. Helena's first broadcast. And the 10th anniversary of the station's first shortwave broadcast.

To contain costs for these broadcasts, a ham transmitter is being used, so the power is limited to 1000 watts. To maximize that power, all broadcasts are in Single Side Band (SSB). The station broadcasts on 11,092.5 KHz using the Upper Side Band (USB).

They suggest the best time for Western North American reception is between 2245 and 2330 UTC.

St. Helena is an island in the South Atlantic a third of the way between Africa and South America.

There are several nice pictures on
