Hello Marcel, yes it is curious and strange. Don't know why it not works with my configuration.

There was no DRM at 1800, so I left DReaM (1.6.1csv) on and noticed that something was playing around 1814 UTC and at that time I started the log. Looking in History it seems like the transmission had started around 1804 UTC. Max. 27.97 dB SNR and only 51% decoded audio. A mostly unattended log. The audio quality was very good when I listened.

A partially unattended log. The DRM transmission started around 18:04, before that was AM. I do not know what happened after about 20:20, may be the propagation conditions changed and the signal dropped. Max SNR noticed 35.5dB.

Hi John, exactly the same noted here, the signal started to drop and I could see on the waterfall that there was a lot of selective fading on the signal, it started to drop out a lot after 20:20. Apart from the slightly late start it had been very good up until then. This may have been to blame: Strong solar flare and CME After days of suspenseful quiet, huge sunspot AR2665 finally erupted on July 14th (0209 UT), producing a powerful M2-class solar flare. The explosion was underway for more than two hours and hurled a bright coronal mass ejection (CME) toward Earth. Geomagnetic storms and high-latitude auroras are likely when the CME arrives this weekend. Visit Spaceweather.com for images and updates.

Excellent DRM service from Radio Kuwait 15540 kHz, between 18 & 21 UTC (15 Jul 2017). Listening in Brazil: https://youtu.be/OZq8gzwyQSM
Please share videos and Keep this Digital broadcast (if anyone on the radio reads). You can always count on the tuning here from Brazil, at least on weekends! |

The signal is too weak here in Stockholm at 1850 UTC. Too high Kp and too much Aurora. No log.

Radio Kuwait DRM, listening in Brazil
Strong signal. The broadcasting starts at 13h and finished at 21 UTC. Congratulations to Spectrum Manager from Radio Kuwait. There is any e-mail or site's radio?

Regarding the TX site, is Sulaibiyah correct? Somewhere I read Kabd. And in Kabd there is a Sulaibiyah road passing by. I found one TX site at 29.513853 N / 47.674414 E in the sandbox. If anyone has a better location than Sulaibiyah then let me know. But the difference in kilometres may not be too different in any case...
