Signals from a VLF transmitter suppress magnetospheric mid‐latitude hiss in a band up to 200 Hz wide located just below the transmitter frequency. These quiet bands take 5 to 25 s to develop and last more than 30 s after the end of transmissions. The modification of the electron velocity distribution function by the transmitter signals is a possible explanation for this new phenomenon.
