Something is going on up there in the ionosphere... Directional colours on my LF grabber are more variable than usual, indicating that polarisation is being stirred up. And there is strong VLF-to-LF
Now also another strip involving DHO with GQD: 138.83 - (23.4 - 22.1) = 137.53 kHz http://df6nm.bplaced.net/LF/vlf_lf_icm_2013/df6nm_151108_0040.jpg 73, Markus From: [email protected] Markus Veste
