I'm hearing some audio on about 6221 KHZ here just above the noise floor since 2302 UTC with man announcer at 2304 UTC. Best here in USB....No ID on songs until 2321 UTC with "My Sharona"-The Knack.
Since 2330 UTC some nice peaks during the songs played...."Easy Like Sunday Morning", "All Day and All of the Night"-Kinks, "Rocky Mountain Way"-Joe Walsh, "Cold Turkey"-John Lennon, "Blinded By the Light"-Manfred Mann, "What Becomes of the Broken Hearted". Man announcer with ID's that I can't make out, but I did hear mention of 6221 KHZ at 2352 and 2359 UTC.
{I thought they ID'd as Iceland Radio, but thanks for the proper ID from refmo!}
EDIT- Listened back on the cassette tape this morning and several clear ID's of "Island Radio on 6221 Kilohertz". Also ID'd some more tunes...amazing what you can do with a simple 7 band graphic equalizer...old technology works for me! SDR and Shazam are simply not in the budget for the foreseeable future...
