Tropical Radio Telegraph Company (Point To Point): Panama City, Managua, and La Lima

Many thanks to SRAA contributor, Dan Greenal, who shares the following recordings and notes:

Notes: With roots over 100 years old, the Tropical Radio Telegraph Company (a subsidiary of the United Fruit Company) used to operate a few radiotelephone stations in Central America during the years prior to the Internet. They often could be heard on various shortwave frequencies transmitting a repeating test message so the receiving station could tune them in. I managed to pick up 4 of their stations in the early 1970's. These recordings are from La Lima, Honduras; Managua Nicaragua; and Panama City, Panama. I have not been able to find the one from Tegucigalpa, Honduras, but maybe it will surface later.

Broadcaster: Radio Cairo

Notes: This is a recording of Radio Cairo from my personal magnetic tape collection. This being the only recording of Radio Cairo i have, i digitized it and then decided to upload it to The Shortwave Archive. The cassette recorder made a hissing noise in the background of the cassette recording, but the loud buzzing was interference from the original recording.

Radio Christian Voice (Lusaka, Zambia): October 14, 1996

Many thanks to SRAA contributor, Dan Greenall, who shares the following recording and notes:

Frequency: 3.330 MHz

RX location: Thamesford, Ontario, Canada

Notes: Tough to log here in southern Ontario, Canada, Radio Christian Voice from Lusaka, Zambia was operating on the same frequency as time signal station CHU, Ottawa, Canada. Here is what 3330 kHz sounded like on October 14, 1996 around 0400 UTC. A good station ID from Radio Christian Voice can be heard in spite of the time beep interference from CHU.
