Stratospheric experiment – we invite you to cooperation!
Last year’s stratospheric experiment with an inductive device operating at a frequency of 14.2 kHz with an airborne antenna with an electrical length of 400 m, conducted under a balloon up to the altitude of 29164 m above sea level, provided – albeit with some issues – a lot of new data. Despite the very low emitted power, caused by both the low efficiency of the antenna and the requirement of the inductive device, we received a very large number of positive reports – almost 23% of the total amount of all reports (the best results were obtained with the use of a longwire antenna and kiwiSDR). The processing […]
