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

Broadcaster: Radio Prague: 1970 and 1999

Frequency: 7.345 MHz

Reception location: Ancaster and Thamesford, Ontario, Canada

Receiver and antenna: Hallicrafters S-52 and Drake SW-8 using a longwire antenna

Notes:

Here is a brief recording of Radio Prague in Czechoslovakia circa 1970. They are heard with their interval signal and announcement in English. The frequency was 7345 kHz.

The second recording was made June 22, 1999 at 1727 hours UTC on 21745 kHz, with their interval signal and multi-lingual ID's, as the external service of Czech Radio.

In 1970, I received a beautiful cloth bookmark from Radio Prague, and I gave it to my mother as she liked to read, and I felt it would be a way to include her in my newfound hobby of shortwave listening. She used it for the next 46 years, and I recovered it in 2016 after her passing, still in amazingly good condition.
