SDR recording catch
0029 Came on with an unshazamable heavy metal song. Maybe over-modulated?
0031 Off
0032 Back on with heavy metal
0033 Significant drop in signal strength, but still there with the music
0034 Off
0037 Back on. Same song?
0039 Off
0047 Back on
0048 Off
Could have been the same station as early as 0009z as well, with a weaker carrier on and off. Someone testing?
