Nothing heard on 12030 here, but the signal on 9680 was very good, about 20db SNR.

I forgot about the transmission and remembered it suddenly around 1820 UTC. Due to much AM splatter on both adjacent channels I had to reduce the IF bandwidth, but some decoding was possible.

Very difficult to receive because of arabic splatter from 9675 kHz. When there is no modulation on the Arabic speaking station, RTI could be heard. Actually, there is AM at 5 kHz. This is impossible when transmitting DRM! And RTI still insists on overdriven audio causing severe distortion. After 1830 UTC 9685 kHz went QRT. Still bad decoding due to splatter from 9675 kHz.
