Hello! Can you post some video or audio to check the audio quality? By the description seems to be Vatican Radio. Thank you!

Wow! It is the Kuwait radio itself that broadcasts in AM on the same frequency! Great audio quality, similar to RNZI. I hope you get it here in Brazil. Grateful!

I observed in the sdr of Holland the signal bursting. Here in Brazil I could not capture. Should not be 500 kW, will it?

It was very good tonight, 3 solid hours and it sounded very good throughout. The SNR varied between 21.0 and 25.7db. They gave an address for reports at 1924 UTC, though this wasn't specifically for the DRM, and it seemed to be the same programme that was going out on 963 kHz and other frequencies as well. Now QRT for the night as 2100 UTC is midnight Kuwait time.

Broadcast in "normal" DRM tonight with 17 kbps AAC+ and P-Stereo in English. Quite good audio quality and "real" stereo and even some quite good English pop music in between the topics. The propagation conditions went sour after 2030 UTC and no more audio.

@John: Most probably they transmit xHE-AAC DRM last night, that was the reason DReaM would not decode anything.

Max. 28.67 dB SNR and about 73% decoded audio.

Impressive signal here.30 dB SNR
Frequency seems too low by 300 Hz
No audio decoding with dream 1.13
OK with sodira 0.092 quite good quality
Total loss of decoding around 1900 UTC perfect before.
It came back about 20 min later

At 1820-1830 UTC Saturday 15/7/17, I am receiving the Kuwait "DRM Service A" on 15540 here in Newfoundland.

I have both the MR27024 (with eight-metre outdoor wire) and the Avion DR-1401 (with Sony AN-LP1 active antenna attached) and neither one is getting as much as 10% decoding. They are both silent as I type and have been for two or three minutes. When the signal peaks, I hear (very good fidelity) sound for as much as ten seconds before it slips down again.

The Avion is showing MER levels ranging from 3dB to about 12 dB (audio decoding starts above that). The loop picks up the best signal when facing just east of North.

Here today very good signal with ~25 dB SNR.

No audio decoding with my dream version but sodira works fine.
