re 'disturbing crackling background noise'
re 9370 kHz R Svoboda 19-20 UT, but fq rather minus 2 Hertz on lower fq flank.
9369.998 kHz tiny S=3 or -108dBm at Perseus SDR in Delhi India subcontinent, (when checked Tashkent signal) at 19.48 UT on March 18.
A string fence seen either sideband some 12 x 100 Hertz buzzy audio strings distance apart seen and heard.
Weak signal also in Finland at Mauno's installation - which favours only mediumwave reception? these days -,
but much stronger S=9+5dB signal noted on central European Russia at Saratov instead.
Stn ID signal heard, then TX OFF exact at 20.00:50 UTC.
