Babcock DRM, KBS logged for 29 minutes from 1100 UTC. Max. 22.42 dB SNR and 78.83% decoded audio. Very poor propagation today. MUF was about 9 MHz for the distance to Woofferton. And why use AFS? AFS with only one frequency in use upsets the Newstar DR111 which starts searching for alternative frequencies, but there are none, so you loose half the transmission.
