    Been aware of ionosondes after reading the excellent "Propagation & Radio Science" by Eric P. Nichols, KL7AJ, ARRL, which introduces a whole world of wonders to us. Quite a lots of ionosondes launched in Brazil. Then there is also that expensive software, which we hardly ever hear of in our forums.

    Using an RTL-SDR dongle you can see these ionosondes move across the screen. Note that the frequency on the HDSDR "VFO" has to be subtracted by -125 mHz. The actual span is from 13.7 - 14.7 mHz.
