This is OK2RZ from the Czech Republic as heard here on 6/5/2016 @ 1945 UTC on 20m. He was speaking about a hail storm there. Some of the USA stations he was working could not be copied here. I was using ,y SDR PLAY RSP with my OCF dipole and SDR Console v3 software. I turned on the LNS, (Low Noise Amplifier), which did improve the copy of his station by lowering the noise floor some.
