B = floor(A) Description. … Other MathWorks country sites are not optimized for visits from your location. The WSPR waveform has a noise floor around -31 dB making it an astounding 10 times more sensitive than FT-8. The transmit period is longer at 2 minutes (FT-8 is 15 seconds), less data is sent, and it is one way further reducing the amount of data sent.
