https://voca.ro/12vcM8p3ZKBw - for the first time I noticed an interesting event of intentional interference of a transmission by a foreign station. It starts at 1'30" of the recording, achieving the effect of complete attenuation in the 3rd and 4th minute. The interference visible in the waterfall passed and returned by approximately +/- 3khz relative to the channel frequency. About 30 seconds after the end of the telegram, the jammer also turned off.
