Live, off-air, recording of the broadcast of two special sequential half-hour programs of Radio Prague International celebrating its 85th anniversary. The programs were broadcast via WRMI, Radio Miami International, using a transmitter at Okeechobee, Florida, on 31 August 2021 from 21:00 to 22:00 UTC on a shortwave frequency of 15770 kHz. The listed transmitter power is 100 kW with an antenna beam azimuth of 44°. The recording includes WRMI station identifications.

Czech Radio officially began its international service on 31 August 1936. Eventually, the service became known as Radio Prague, then for a brief time in the 1990s as Radio Czechoslovakia International and most recently as Radio Prague International. Radio Prague International is mostly an on-line service now with its own transmitters having been shut down on 31 January 2011. It continued to broadcast over the single WRMI transmitter in Miami and currently relays its daily programs in English, French, and Spanish using the WRMI transmitter complex in Okeechobee.

The special anniversary programs include archival recordings, interviews, and comments from listeners. The first half-hour program is in English followed by a second half-hour program in French.

The broadcast via WRMI was received outdoors on a Tecsun PL-880 receiver in AM mode with 2.3 kHz filtering and a Tecsun AN-03L 7-metre wire antenna strung to a nearby tree in Hanwell (just outside Fredericton), New Brunswick, Canada. Reception was mostly quite good.
