Live, off-air, recording of a morse code (CW or continuous wave) transmission in English from station SAQ, Grimeton Radio, Sweden, on 16 November 2022 beginning at 16:00 UTC on a very low frequency (VLF) of 17.2 kHz. The signal originates from the historic Alexanderson alternator transmitter at Grimeton near Varberg on the southwest coast of Sweden, running at about 80 kW. The antenna is essentially omnidirectional.

The transmitter was tuned up before the broadcast with many sequences of VVV VVV VVV DE SAQ SAQ SAQ being sent. The message, titled UNESCO 50th Anniversary Telegram, began at 16:00 UTC, lasted about 9 minutes and 30 seconds, and is as follows:

The broadcast was received by the Web-interface wideband software-defined radio at the University of Twente in Enschede, The Netherlands, with a "Mini-Whip" antenna in CW mode with 0.40 kHz RF filtering and real-time noise reduction. The CW tone is about 760 Hz and the message was sent at about 15 words per minute. Reception was fairly good with some occasional atmospheric noise (QRN).

Notes: Radio Taipei International was the old name of Taiwan's internation radio service. Its name changed to Radio Taiwan International on 2003. There are many online services which can transcribe voice to text, but with mistakes. I don't understand Russian, could not correct the mistakes. Shenyang is located near the Russian Far East region. I could clearly hear the Russian language broadcast.

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.
