I've been receiving a steady tone on the upper side band (USB) of this frequency. I had hoped to receive this broadcast fairly well during the summer since REE changed their adjacent frequency away from 15120 kHz. I'm not entirely sure about the source of this steady tone as it doesn't appear to be co-channel interference from another broadcast.

This partial log just shows the better part of the broadcast.

Tone is shown in lower right window slightly highlighted by black circle. This tone is present from 15120 kHz through 15122 kHz.

DR111 with external, active antenna

100% CDA tonight in this unattended log. Even the Doppler stayed within the plot area!

DR111 with external, active antenna

Perfect decoding, 100% CDA. The 5.7 Hz max. Doppler value around 1827 UTC seems to be a spook caused by the DR111.

Otherwise the max. Doppler would have been 1.71 Hz at 1954 UTC.
