Hello VLF! Interesting screenshots on my VLF grabber http://rn3aus.narod.ru/VLF/index.html. Selective fadings are varies from night to night: 05-06 August: http://rn3aus.narod.ru/VLF/vlf-wide-capt85-selfad.bmp http://rn3aus.narod.ru/VLF/vlf-wide-capt86-selfad-rise.bmp We can see 3 beams with delay abt 0.17 ms, 0.5 ms and 3 ms. 3 ms = 900 km! 06-07 August: http://rn3aus.narod.ru/VLF/vlf-wide-capt92-selfad.bmp http://rn3aus.narod.ru/VLF/vlf-wide-capt93-selfad-rise.bmp 3 beams 0.33 ms, 1 ms and 2 ms... Doppler shift also can be explained as result of reflection from moving terminator (the grey line). -- Alex RN3AUS |
